smooth scrolling? - Nexus One General

what's the reason that our phones don't have smooth scrolling across the home screens like the iPhone does? even the way the scrolling is in the weather /news app would be perfect

I think you might want to send your phone away to be replaced

uhm... looks pretty smooth to me are you using the stock rom? maybe try a factory reset?

This is a documented thing. It is smoother than the droid, but compared to the iPhone it is choppy, hopefully it is a software thing that can be fixed.

Try helixlauncher

I know what you mean. The iPhone is smooth and Nexus is occationally choppy & sometimes stutters - its simply not as smooth.
The best way I can describe this to persons not familiar with iPhone is screen scrolling on the iphone looks like an animation with about 25~30fps, the nexus one looks like an animation with about 5~15fps. While not the end of the world, it certainly annoys me (and others)!
I have noticed also that the appearance of this less than smooth side scolling is further visible with live backgrounds & lighter wallpapers (where as a pretty much black wallpaper seems to reduce the visible stuttering).
Does the iPhone use OPENGL thoughout its OS - I seem to remember reading something like this. Perhaps if launcher was redone for OPENGL...?

This annoys the hell out of me. what annoys me more is that our phones are capable of silky smooth scrolling. It seems that the gpu downclocks itself most of the time and just refuses to display more than 5-10 fps. it's certainly not a limitation of the hardware since reducing the graphics load by using a stationary wallpaper (one that doesn't even slide side to side like the stock picture wallpaper does) or just black still results in the horrid framerates.
i've found a workaround however. using a live wallpaper which demands a high framerate such as silhouette or my current favorite: unixseb's bootanimation: http://forum.xda-developers.com/showpost.php?p=5697670&postcount=28. with either of these wallpapers running our phones seem to kick it up a notch and give >30fps silkyness :-D
this is all with helixlauncher2 btw

it drives me daft as well everytime it happens i think to myself this never happened on the iphone ,it just stutters before it moves and when imputting phone numbers in ,there just seams just a slight delay and considering this has a faster processer it should be lightning fast no stutter ,and if you cant see it your lying to yourself ,or you have never had an iphone, slower processer but the ui is just much quicker, but dont get me wrong i wouldnt go back to the the 3gs from my n1 but i will probably move to the iphone 4g

Because the iPhone is a nasty black screen with nothing but icons but the Nexus One has Live Wallpapers / normal wallpapers, interactive & updating Widgets, and a screen with 2.5 times the resolution?

That is no excuse, Sense has this and more; and the scrolling is quite silky. It obviously just isn't a smooth, Launcher2 I mean.
Notice that Helix Launcher2 is the Nexus Launcher2 but it is 10x more smooth as that standard unchanged home. Obviously Google just didn't do something right, the scrolling is down right pitiful on the Home screen - where it could have been easily as smooth as the iPhone.
I get what you mean though, the iPhone doesn't have much to slow it down. Therefore no reason to be not smooth.

Basically, this. The resolution thing in particular is a huge factor. We aren't just talking about merely double the resolution, here.
Try something, guys. Dig up your oldest, ****tiest laptop/PC. Increase resolution to the highest it will support and see if your performance suffers. Or try this with a game, for that matter, and compare the framerate of 800*600 with 1920*1200.

from what I've read, apple uses a different physics engine than android.
I have to say that indeed the iphone has such a better swiping/scrolling experience than my N1 (even w/ an overclocked desire ROM). The N1, despite it's less powerful GPU as compared to the iphone's is supposed to compensate with its snapdragon cpu. It would be interesting to see how the samsung with the a better cpu and gpu will perform.
from: http://androidandme.com/2010/03/new...bird-chip-to-have-3x-gpu-power-of-snapdragon/
Here is a GPU comparison for some of the leading smartphones:
Motorola Droid: TI OMAP3430 with PowerVR SGX530 = 7-14 million(?) triangles/sec
Nexus One: Qualcomm QSD8×50 with Adreno 200 = 22 million triangles/sec
iPhone 3G S: 600 MHz Cortex-A8 with PowerVR SGX535 = 28 million triangles/sec
Samsung Galaxy S: S5PC110 with PowerVR SGX540 = 90 million triangles/sec
And for comparison a few consoles:
PS3: 250 million triangles/sec
Xbox 360: 500 million triangles/sec

has nothing really to do with resolution in this case it have everything to do with the launcher. If resolution was the factor then home replacements like pandahome would not but insanely smooth on my N1.

Have a Touch and a N1 and can't really tell any real difference between scrolling on both
Sometimes I wonder in N1 users are just more anal that most

has nothing to do with being anal but some people just notice smaller details than others. fact is that the scrolling has a low framerate like what everyone else on here is saying. if ur on cyanogen mod try scrolling from one home screen to the other as slow as possible and see how it stutters its way across and if you do it on an iphone it will go across perfectly smooth

Sense on htc desire is very fast and smooth for why on nexus no ???? for why im perturbed

this is one of the worst things about android for me as well - just a small thing like this has so much of an effect on the user experience, and it's why people always will say the touch screen is 'better' on an iphone than an android phone (especially stock) when they're side to side.
i think it's basically to do with the fact the gpu isn't used. there's a link here about it where people with a lot more knowledge than me shed some light on the subject as well.
also i seem to remember it having something to do with obtaining licences from the cpu manufacturers or something to get access to the gpu code or something or other. although i cant find the link to where i read that and i dont fully understand what i said lol so take it with a pinch of salt.
://code.google.com/p/android/issues/detail?id=6914
(add http in front of the link above btw)
either way i think this is definitely something google needs to address.

but I was just comparing this to an iPhone 3g yesterday and they both seemed the same to me. scrolling between homescreens was equally choppy (or lack there of, imo). or is the iPhone 3gs improved over the 3g? either way I think its a rather small complaint.

well the 3gs is almost twice as fast as the 3g (if im not mistaken). so there is a difference between the two. i used to compare my 3gs to my moms 3g and would tell her she needs to upgrade. LOL
and the 3gs is smoother than both n1 and 3g scrolling wise. Im sure itll be a software fix down the line.

My nexus takes a beating by Incredible at verizon!

Not exactly....
But had 30 minutes to compare.
Cleared cache and rebooted my nexus...had full signal in the store.
Well on good....screen Res seemed richer on the nexus. Close-up revealed finer contrast than incredible.
Incredible just flew...app to app and thru menu items tho... significantly faster than nexus.
(I'm on Desire remix rom btw).
Browser to browser: interesting: speedtests: nexus consistantly 2500kbps...incredible: 1200.
But on graphic heavy sites incredible was marginally faster most of the time. Nexus has initial lag connecting then was faster.....Incredible seemed to have none of that initial lag. Don't know what that means. (I have under 25 Apps installed).
Camera shots were actually fairly similar....incredible was better by a bit.
I like the feel of the incredible better much more secure due to that 'race car' back.
The gallery and music apps are really nice.
So ...I think we're oneupped out of the box a bit....
We'll see if folks mod it to any degree.
You can really compare a ported rom to a rom built specifically for a device.

Honestly dude after reading your post it sounded like the Nexus One came out on top by hair...
Yeah....not really a valid comparison.
Apples to oranges. Different network, one is a near virgin unit and your N1 is loaded up with apps & data, you can clear all the cache you want but there are still background tasks.
but even given all of that it still sounded to me like the Nexus wONE

Isn't Incredible on Verizon and N1 on TMo/ATT? It's the provider.
I didnt see where or if you mentioned whether or not you were using stock with the pathetic ram or a custom with appropriate ram use. But not only does the incredible have more ram, it probably actually uses a lot of it unlike the nexus. maybe after an update the nexus will be just as quick.
I was at first going to call the OP retarded for this horrible comparison. Instead though, I will just say - flash Cyanogen, and you will see which one is fastest.
And then say more.
These Desire ROMs are just horrible on the Nexus, and offer a very noticeable speed difference from stock or any other non-Desire ROM. That's why when Froyo is released, I will stay off of them for a while. Not to mention your using Manup's.. its based from one of Paul's old builds, Alpha 10 I believe.. can't remember.
I'm positive though regardless, the Nexus on its native Android version or updates in the future are up to par or faster than the Incredible. Don't spread a bad name please, it really urks me when people inform people of false information. Or non valid and a long stretch from the truth accusations.

The 2 phones have the same amount of ram..
compare a stock nexus one with a stock incredible.

It's not a fair comparison because the Incredible is running Sense UI written for the Incredible.
The N1's ROM is a hack job.
And the Desire's kernel hasn't been released yet, which is the reason for the any lag you might experience on the N1.
As it's been said, there are a number of different factors that will influence a comparison like this, probably most notably the difference between a beta ROM and one built and polished for one specific phone.
But who cares? Same team guys. It's all Android and that's what counts.

Indeed. I'll gladly let the Incredible be the #1 phone if it sales 1 million+ phones fast and gets the market growing even faster like the original droid did

Could you elaborate more on this? I'm interested in seeing how the 8MP camera is compared to the 5MP on the Nexus One...
The only reason the Incredible "seems" faster loading apps and such is because SenseUI doesn't have the animated window transitions. Turn them off in spare parts (like I have) and it's just as responsive, if not more.

Looking at a 8MP at normal 100% and a 5MP 100% they will look the same I believe. If you zoom in or look at one at its full resolution, you will see the difference. Since both phones are using the same screen size and resolution, any difference will be unnoticeable I believe.
I have photos from my girlfriends 12MP camera and had added them to my Nexus One SDcard. Since they get sized to fit my N1 screen, I never noticed a difference in detail unless I zoomed in.

Ah, I see. I just thought that the Incredible's photos would be more crisp and detailed, considering the higher resolution. But I love the camera on the N1 and I use it a lot, so I can't complain.

Galaxy S (Epic, Captivate etc) VS EVO Comparison and thoughts.

I just got back from the ATT store and did a head to head with the Captivate and my EVO. I had briefly looked at the Vibrant earlier this week but didn't have time to really put it through it's paces. I have a couple more weeks before I have to decide if I keep my EVO and I have been on the fence about keeping it or bringing it back to wait for the Epic.
I figured that I may not be the only one on the fence so here are some of my observations.
For reference, I am fully rooted, running Fresh 1.0.1 and Netarchy's over clocking, under volt, 55 FPS kernel 3.6.4. I was overclocked at 1.152 ghz (on demand 128mhz min) for the duration of the comparison.
SIZE:
I was surprised that the EVO and the Captivate (Galaxy S) were about the same size width and height. I thought the Galaxy S would feel much smaller. Even though the Galaxy was a couple mils thinner and and a couple oz lighter. The way the EVO is tapered at the edges makes me feel that the actual volume of these devices were similar. I would say they are in the same ballpark size wise. The larger screen of the EVO was very obvious. The Evo's screen has 15% larger surface on a device that was about the same size and I liked that.
PERFORMANCE:
1. MENU NAVIGATION: scrolling fluidity appeared to be more or less on par. There were a few times the Galaxy was perhaps slightly smoother with scrolling through menus, but both seemed to stutter occasionally. DRAW
2. BENCHMARKS: Linpack scores were about 7.9 on the EVO and 8.3 on the Galaxy. Obviously the Hummingbird is faster and with Netarchy's custom kernel you can assume that the Snapdragon is optimized for the best possible performance and battery consumption. I imagine once custom kernels come out for the Galaxy, the performance gap will widen. For now, they are pretty close.
Quadrant scores on the EVO was about 560 and the Galaxy was 850. I have gotten higher scores on quadrant with previous kernels. My EVO's previous scores were about 610 on 3.5.1. Netarchy might have dialed back the performance a bit or I might have been on "performance" in Set CPU. Obviously 3D rendering was vastly superior on the Galaxy S, no surprises here.
4. BATTERY LIFE: I ran parallel applications on both devices, running benchmarks, playing games, surfing the web and watching online videos etc etc. I would constitute this as heavy usage. Both displays were set to auto brightness and I would say that the brightness on the screen looked equal to me. Durring this time, the battery on the Galaxy S decreased by 10% and the EVO by 12%. This is not exactly scientific but leads me to believe that the Galaxy has a 20% advantage in power effiency over the EVO. This is despite the fact that the Galaxy is not running an under volted custom kernel. However I was overclocking the EVO. I am not sure if they would be closer if I was running at stock speeds.
I can't wait for the day where I can watch video's and surf for 10-12 hours nonstop so I don't have to think about conserving power.
SCREEN
1. Resolution: The Galaxy was clearly inferior. I discussed this in a previous post. Pentile screen technology deployed n the Galaxy means that true addressable resolution is actually 392x653 not 480x800. This was very noticeable to me in graphics, photos, video and especially text. I hate to say it but Steve Jobs was on to something with his choice of a high resolution TFT. EVO really wins for readability.
2. Saturation and contrast: The Galaxy is superior. It is a matter of preference if you think it looks natural or not but benifits of S-AMOLED were very obvious. Everything was clearly more saturated on the Galaxy.
3. Viewing angle: Galaxy wins again. Deviations from face on viewing produced lower contrast ratios on the EVO's TFT and a kind of greying effect. Viewing angles on the Galaxy were almost 180 degrees with no loss of saturation. Amazing.
4. Brightness: The Maximum brighness setting on the EVO was brighter and more vibrant than the Galaxy S. On minimum brightness the Galaxy was far brighter. I am not sure how these settings relate to power consumption but on Max I prefer the EVO. On minimum the galaxy was still useable in the brightly lit store, the EVO's min setting looked washed out and I wanted to turn it up.
5. White balance: EVO's whites look much better. The Galaxy S' whites look grey or blue this made it feel dirty or dingy to me.
Watching you tube on standard (not HQ) was much more watchable on the EVO than on the Galaxy. This might be a network thing, but resolution, size and even colors looked better on the EVO. I was surprised. HQ on the EVO blew the Galaxy away.
Anyway those are my impressions. I am surprisingly no closer to making a decision. With all the buzz surrounding the S-AMOLED screens I was expecting to be blown away by the Galaxy's display but in reality it was more of a draw. In many ways I felt the EVO's display was superior. If power consumption and processing power were equal I would say EVO. I guess what remains to be seen is how the developer community will embrace these Galaxy S devices and what kinds of perfomance/power enhancements can be applied to the Hummingbird with 45nm. Clearly the EVO has been embraced my the developer community and if Gingerbread can be shoehorned on to the EVO, it will, regardless of HTC's support (Cyanogen for example). I don't want to be left in the cold when Gingerbread arrives.
I will say one thing. The iphone 4's display looks amazing. I have no intrest in owning an iphone because of the limitations of the platform but they really nailed it. I want a device with a 4.3 inch screen, 330 pixel density, TFT white balance and S-AMOLED viewing angles and contrast running android please.
good write-up - seems neutral as far as opinion and also like you took your time. Was looking for a writeup like this, thanks.

Thanks for that detailed comparison post, you'll have to be patient for those specs but no doubt better devices are coming..
The iPhone 4's display is indeed amazing but personally left me wanting a bigger screen (even more so than on the 3gs) & then you would have to accept its platform-network..
I still would like to check out the upcoming Samsung Beam (although I wish it had a faster processor & larger screen, I'm quite curious to see its built-in projector in person).
If you can wait until the end of the year you'll likely have a better idea of the best near-future devices otherwise the EVO with 2.2 is the most appealing to me at present.
BTW, anyone still think official Froyo 2.2 on EVO is going to happen in July?

Well, they did release the source fairly quickly (about a month or two after launch, idk exactly since I got my evo a week before the launch), and both sprint and htc said we should have it in july. I guess I'll wait until the 31st to make any solid predictions, but to me the release date is still up in the air.
btw- Great review. Was interested in the galaxy because of its performance but i'd rather have better looking movies than games so the evo's still on top...for now lol.

I agree about the iphone's screen size. It is just a little too small for 2010. The clarity however is really compelling. It is the first time I have been able to read text on web pages without zooming. Browsing and reading text is probably what I do the most on my phone, even more than making calls.
The Beam looks cool! I haven't seen that yet. The projector could be really useful for business presentations and also movie watching. No need for a TV or HDMI out when you can just project Avatar on the wall! Contrast and brightness seems a bit low.
I don't now about official Froyo in July. HTC has said before the end of the year. Sense integration will take some time since it permeates Andoid extensively. I have this feeling that the Epic might be released with Froyo in late August early September. Samsung's Touch Wiz seems less pervasive than Sense and Samung seems hellbent on taking down HTC. Samsung has said Froyo will be available on Galaxy S phones in Korea in early August. I will be happy with Cyanogen 6 which should be any day now.

I have this feeling that the Epic might be released with Froyo in late August early September. Samsung's Touch Wiz seems less pervasive than Sense and Samung seems hellbent on taking down HTC. Samsung has said Froyo will be available on Galaxy S phones in Korea in early August. I will be happy with Cyanogen 6 which should be any day now.

Yeah I hope the iPhone 4 screen will motivate competitors to raise their bar but its awesome text clarity still seems tiny sans zooming regardless of its legibility so I'm hoping for larger screens. I was also disappointed with how weak the iPhone 4 speaker seemed. Didn't seem to compare to the EVO's speaker. The Samsung Beam apparently has "65 decibel" stereo speakers..
Here is a much longer (11 min) Samsung Beam video & I've seen other videos showing off annotated powerpoint slideshows & projection capabilities. Here is the Samsung link for its Beam model. Again I wish they put in a faster processor & larger screen but they claim up to 50" projected (a viewing size of five to 50 [email protected] meters) !
I prefer Launcher Pro or even stock 2.2. to Sense or Touchwiz & I hope Cyanogen 6 delivers (EVO has all that inspired dev support that new Samsung devices have yet to materialize which is a significant selling point ATM)

If I was aware of the Captivate, I would have waited for it instead of switching to spring. It's too late now.
Captivate
+faster cpu and gpu
+better battery life
+much lighter
+thinner
+screen is better in some ways
+16gb internal storage
+AT&T network (what I came from) is better around here
+Might end up selling more Galaxy S phones and hence have better all around support
+bluetooth 3.0
Evo
+4g (although 3g on other carriers is often just as fast)
+kickstand
+better front and rear cameras (but probably not by much)
+great user support community
+larger screen for the real estate
I'd like to see some solid reviews but I would call the Captivate a winner. I mainly bought the evo because it was the first android phone with supposedly a quality camera. Unfortunately, that hasn't proven true. If the camera isn't going to be all that good, I would prefer to have something that is better in most other ways.

Please show me a carrier that gets 4 Mbps on 3G.
Even so, that won't be a plus once the Epic is out.... but then that phone alone has its own set of pros and cons.

I've pulled 4-4.4 Mbps on AT&T 3G on a 3GS (Wilkes-Barre/Scranton area in PA). T-Mobile's 3G can also pull those speeds in certain areas (ones upgraded to 21Mbps).
These Galaxy S phones look like great devices. But I keep saying, I'm gonna have to wait for the next Galaxy S generation to see if Samsung actually starts supporting their devices (and see how big the community for their devices grows) before I jump from an HTC android device.
I'm gonna head to T-Mobile tomorrow just to play around with a Vibrant though. I'm really looking forward to it! The new TouchWiz (though kind of an eyesore) has some really cool features that I wish HTC would come stock on Android (or be added into Sense).
The lower resolution is a bit of a bummer but does the S-AMOLED screen make up for it even the slightest? After playing with my cousin's iPhone 4, I noticed that even though the screen is very sharp and crisp, it's only noticeable when it's up close right in your face. When held at regular viewing length, the screen really looks no different than my EVO. In fact, my cousin even admitted that he preferred the EVO at regular viewing length because the screen was bigger and easier to read.
Hopefully other companies do what Apple decided not to do and put that high resolution to good use on a large 4 inch+ screen.

T-Mobile: 6.10 down / 1.29 up using Speedtest.net's Android app on the Samsung Vibrant yesterday (7/26) in Brooklyn, NY.
4.82 and 5.00 down speeds achieved within the same 5 minutes in the same spot (in case the 6.10 was a fluke).
A few things:
The screens on the different galaxy s models look different when compared side by side so you will have to wait for the epic too actually see what it will look like.
Nand on the other devices is partitioned in a ****ty way so speed can be an issue with the s in some ways. The epic should not have those issues with only 1gb.
The evo, hacked, is at their peak of its power so comparing it to a stock unit isn't fair.

not trying to threadjack, but the beam... the projector is niche, but it kinda makes me feel funny in my pants. not for sprint though, so we'll have to wait for at least a year for something like that in the u.s.
I really only want a powervgx gpu because those phones are going to have the best gaming experience. Adreno's hardware is nothing to turn your nose up at, and they can draw like 22M triangles/second but their fillrate leaves something to be desired.
The bottom line is to get games to run optimally on any gpu, they have to be configured to run with your gpu. The fact that the iphone has a powervgx, means that the droidx, samsung galaxy, and any other phone with a powervgx will by default have a smoother, more compatible gaming experience out of the box.
That and qualcomm won't give us any decent drivers for the adreno. I wish they would just OS their userland drivers and let the community show off the muscle of the adreno.

T-Mo really can get those speeds.
To the person who said 4mbps on AT&T, you're either reading (holding? ) it wrong, or you're a troll. Unless you're in Chicago (their only 7.2 market so far) you physically can't get above 3.2mbps. The best I ever got on AT&T is 2.8mbps

[DISCUSSION] Scrolling and touch screen issues compared to iphone 4

I don't think it's a problem specific to me, but to all Android phones.
I find there are three scrolling/touch screen issues compared to iphone 4.
1) I'm now using Desire Z at 1.4ghz, but if I compare scrolling smoothness e.g. in Gallery or in Internet web page to scrolling on the iphone 4, iphone 4 is a lot smoother and easy on the eye.
2) Also, there is always a like a split second delay when trying to scroll. e.g. you flick the finger, then a split second later it starts to scroll. It's a minor thing yes but it's a bit annoying. You don't get anything like this in iphone 4. However, in the developer app "Multitouch Vis Test" it shows the touchscreen actually reacts straight away... so that seems to be a software issue within Android
3) Another thing, the phone doesn't respond to very fast flicks.
A test on the Multitouch Vis Test confirmed this. If I flick fast, only one point of the screen is registered, but no more - meaning that screen will not scroll.
On the iphone 4 there are no such issues like these.
Do you all agree?

Well, it is Apple, all their devices have little lag. Until the new device comes out and they cripple it with an update.
I think Android wasn't designed as much for style (till Gingerbread) or speed. But for usability. Froyo made it faster.
Any phone with an OS designed for it and it alone will be faster than a "Here, have this, put it on a phone" OS. The G1, N1 and NS will probably be a bit faster than a Desire Z because the OS updates were designed for them. Or whatever, I'm just rambling on...
I would have to completely agree that things just aren't as fluid and quick as iPhone, however Android is not yet polished and was never meant to be all about beauty. I'm sure it will come in time but for now it's about the endless functionality.
Apple is more about a pretty, but sterile environment. They'll always look pretty and run smoothly, but you'll have them restricting you in every way possible. Which can be a good thing for a lot of people (especially those who are not techy). I would never trade my Android for an iPhone, but I do wish that it ran as fluid.
I have always been pretty happy with the scroll speed, haven't used an Iphone much though.
.... But have you tried Launcher pro with the elastic scrolling on and min scroll speed set to max? Give it a try.
I thinks it's more the smoothness and consistency than the speed that is the issue. There is a stutter in most programs and it can seem quite jerky on menus with images that load as you scroll.
At least we don't get dumb gray checker board patterns when scrolling fast

Dont agree sorry. Scrolling seems fine to me, and as mentioned above i would trade slightly worse scrolling/touch input for actually being able to use the hardware i paid for how i want to. Only used my flatmates iphone 4 for a short period of time though (then got bored haha) so may not have used it long enuf to notice.

That's weird when I used my iPhone 4 I got checkers when zooming in or scrolling. It was so annoying made me miss Android

I had some of the 'lag' that you mention while using the stock ROM that my device shipped with (HTC Sense 2.0 over Froyo) The stock ROM seemed to be built around beauty rather than function. It looked great but consequently slowed my device.
Since flashing CM 6.1, the device is much more responsive and I have no lag. That is without overclocking. When overclocked, the device is that much more amazing.
I have not played around with the new Iphone 4 much but when comparing my device to my girlfriends Iphone 3GS, the Desire Z blows it out of the water.
well you can't really compare them. iOS 4 is designed to run a more simple os overall. For the longest time iphone didn't have multitasking which made android appear to be "sluggish" but if you dissect an iphone's hardware with an android phone, you will see that specs today are similar and on some androids even better. Hypothetically I believe that if you were able to port ios 4 to a desire z or g2, you'd probably see better performance that the iphone itself.
I completely agree. That's one thing I miss from the iPhone, the smoothness of the scrolling and ui polish.

I use LauncherPro at 1.4GHz on Stock ROM.
The reason there isn't very smooth scrolling on android is because android doesn't have gpu accelaration.

This. The g1 only supported one instance of opengl at a time, so the ui is mostly cpu based. I really wish they would revamp this

Your thoughts on the unsmooth graphics?

Why is the GUI interface and overall graphics on the Atrix so unsmooth? I'm assuming the cause is the large resolution, and maybe a crappy LCD screen? I'm thinking its more the LCD screen. Since my iPhone 4 has a resolution close to if not the same as the Atrix, and has a PowerVR GPU one model lower than my Samsung Captivate, and its 10x smother than my Atrix. Just don't understand why you would build a phone with so much power and screw it up with an under par LCD screen. What are your thoughts?
Sent from my MB860 using XDA Premium App
I believe it's because atrix lacks proper software optimizations which motorola is too lazy to provide.
Meh.... If you look at quadrant advance - lets assume its accurate and not argue for a sec
The tegra 2 doesnt have the greatest 2D performance - in fact quite low...
...what are you talking about? I've never seen any unsmoothness on my Atrix, except in the Gallery app when zooming in on high res photos. Everywhere else, its far smoother than my 3rd gen iPod touch, which itself was no slouch.
That said, I use launcher pro instead of Motoblur, so maybe that has something to do with it.

I noticed choppyness with live wallpapers. Also, when i first open the keyboard to type, the first couple of letters don't register so i have to retype that all again.
I think... WHYWHYWHYWHYWHY?!
I mean single core phones run smoother wtf =/
the lwp lag really gets me =/
Motoblur...
Froyo doesn't have gpu acceleration for the ui, or so I've been told. It's far worse on other phones. When gingerbread comes out you'll see a significant difference.

I'm coming from Windows Mobile, so everything on Atrix looks smooth to me
But seriously, I think it may be a combination of the GUI not being hardware accelerated and whatever software/widgets you've got running in the background.
It's definitely not butter smooth, but it isn't that bad either.
Use a third party launcher, and freeze out the Motoblur stuff. I was also really disappointed when I first saw general navigation around the GUI and saw how choppy it was. Try Launcher Pro, or Go Launcher Ex and get rid of all the preinstalled crapware. It makes all the difference and you'll be much happier with performance.
Android 2.3 and below do not have any hardware acceleration. Your iPhone has tons of hardware acceleration to make it feel faster (when it's not)
My Atrix feels fast.
I'm also coming from a Samsung Captivate which is crap tons smoother. Its not cause of the launcher, nor the lack of hardware acceleration in froyo. It does it with all the launchers. I'm probably just spoiled with my Captivate.

live wallpaper lag.. really annoys me but then it reminds me how much battery I waste with it enabled and it makes me turn it off again ASAP
Its because the Tegra 2 sucks at everything but playing douchy Tegra Zone games. In other words your SOC was built by a graphics company. So 3d rendering is great but 2d and everything else sucks. Great GPU, very sad and not optimized CPU. I doubt gingerbread will help that much. Sorry guys
Edit: I'm no fanboy but my thunderbolt runs buttery smooth at everything and I run multi pic live wallpaper with 7, count it 7 different wallpapers and the 3d cube transition effect. This is with sense and at least one widget on every screen, most have two.

The thunderturd is an evo with lipstick.
The graphics are not even potentially shown...
Tegra 2 uses a different processing post. Therefor showing a weaker performance on 3D and 2D processing...
Just chill and relax. Enjoy the phone a bit more. Don't expect it to make you breakfast either.

Its funny yall start dissing on the thunderbolt when I didn't bash the Atrix at all. Everything I said was aimed at the Tegra 2. Then I gave an example of a single core phone that runs way smoother than the Tegra 2 and most likely why that is. I just posted an explanation referring to the topic of this thread. Honeycomb uses some better hardware acceleration so the Tegra does do better on HC but it won't come close to the TI, snapdragon, or hummingbird dual core processors.
But clearly I'm talking to some serious fanboys here so there is no point in trying to state facts.
Edit: As far as the evo with lipstick comment goes I dont see what sense that makes considering the thunderbolt has more RAM and the msm8655 which is a huge leap in speed and efficiency from the processor in the evo.

Nexus 4 Input Lag

Hey Guys,
ever since i use Android im kind of annoyed by the responsiveness of the tochscreen. Even with state of the art smartphones like the S3 (ICS version) there is substantial lag. (compared for instance to an iphone)
I was really excited when JellyBean was announced because as it seems, it addresses the issue.
However when i tried an S3 with JellyBean i still felt the lag.
My question is whether the Nexus 4 actually matches the Iphone in responsiveness.
(I do not mean the stuttering when opening for instance the app drawer, i mean the pure relation of the finger touching the device and the quickness of the response of the device.)

It uses the same new technology as the iPhone 5 which brings the touchpanel closer to the front glass meaning responsiveness should be significantly better. It's called In-Cell Touch display if you want to Google it.
You'll get a real answer when the phone comes out. Or check video reviews. We know as much as you do at this point.
Thanks for the answers enviii and ralexand!
The thing is, this input lag issue is very rarely adressed. It seems to me as if most poeple dont even notice it. It may be that im kinda picky there but its definitely a very important feature for me...
As the device has been released I would appreciate someone talking about the mentioned issue, who actually posseses the phone.

Well for me the scale is definitely the iphone. (even still the 3G when scrolling homescreens) Also top notch Windows Phones offer very good responsiveness.

I guess it would be better for you to stay with iPhone.
EDIT: Deleted
iPhone relies on a system that basically delivers all or much of the available resources to the graphical interface when scrolling, which slows down or stops whatever else the phone is doing at the time (ie stops loading a web page when you start scrolling or momentarily pauses a download). This, along with a very strong GPU, is much of the reason for the smooth interface. (note: this info was taken from an interview with a Google employee, probably about a year or less ago. Could be outdated, but I believe it's still true...)
4.1 ramped up graphics rendering FPS to 60fps. This, a long with a strong GPU, S4 Pro processor and (mainly) 2 gigs of ram should result in an incredibly smooth UI. Also, the curved glass on the edges of the screen have been noted to give a much smoother feel to scrolling, whether it's a placebo effect or not will just have to be determined over time.
Long story short...yeah, this thing should be smooth as butter (pun intended)
Also iOS is more optimized since its on for few devices.

actually the big main reason for smoothness of ios vs android is that...every single application (basically everything) runs on virtual machines on the android unlike ios.. so it is true that the beefier the hardware the smoother the device..and thats y ios is able to run smooth even with lesser hardware..

Thanks for this in-depth information. I have already known some of this from posts by google employees on their google+ pages.
I hope the changes introduced in JellyBean and the sheer performance of the Nexus 4 can overcome the innate performance issues of Android.
When someone has made first real life experiences with the device please let me know

I have a Nexus S (awaiting a 16GB N4) and I can tell you that Jellybean offered a tremendous improvement in smoothness.
As for the lack of improvement with the S3 and Jelly Bean, do keep in mind that is not "stock" Jellybean, Samsung may have avoided using any of the "project butter" code for their own GPU rendering.. Only Nexus devices are guaranteed the advertised improvements listed by Google, once an OEM touches there's no guarantee.
Only the framerate is high. There is MASSIVE input lag of 100-200ms on every Android device. As evidenced in every video of the Nexus 4 the screen lags behind your finger by 1 inch or more when swiping. This makes it feel extremely sluggish and unresponsive in apps like Facebook and games like Canabalt are unplayable.
I noticed this too when I first started messing around with my N4.
A test I like to do is use the calculator, and see how many numbers I could hit before they would be highlighted (which I assume means the device starts registering the command). For some reason I was getting 2 (almost 3) punches before the device would see it. On my Wildfire S and my iPod Touch the input lag was never this bad.
Amazingly, I actually found a solution. I don't remember if I turned it on myself or if it came on by default, but my phone had the "Magnification gestures" on. You can find them in the "Accessibility" settings. I turned it off, and BAM! The input lag has practically disappeared. I don't know why it was doing that or how it's related, but this has effectively fixed it for me. There may still be a slight input lag, but it's small enough that I can ignore it. Before it was easily over 500 ms.
Hope this helps.
I've made sure that's off on every Android device I've tested. The input lag is still considerably worse than the iPhone.
