2GB of RAM unnecessary?! LOL

This is the 4th time I've opened my task manager today and realized I was using over a gig. It easy to use over a gig when its there

a phone OS using more ram than Vista??? not a good sign. God where are the AOSP roms already :crying:

Kernel knows it has more memory available so apps are more likely to stay in their suspended state, rather than removed from memory.
But I enjoy the 2GB of ram for sure.

Using RAM is not bad; needing RAM is bad. Android 4.0 can easily run with less than 400 MB, but some things can be a little faster when they don't have to constantly reload.

This. Everything switches back instantly!!
One of the most frustrating parts of the HTC OneX for me was when i was reading a long page of comments on sites like the verge or typing up a forum post. If i left the browser to reply to a text or facebook notification, and then returned to the browser it would always reload a page, and at the top.
Even the (heavy) Sense 4 launcher would have to load up every now and then.

i wasn't making fun of android, i was making fun of touchwiz. too much bloat.

If the RAM will mean Nova Launcher wont reload itself as much as it currently does on my Incredible, then that's reason enough for me.

Having had the 1X for a month the 2 gb ram was one of the reasons I switched.

The 2GB of ram (and LTE) has been excessively downplayed by the International crowd because..well..they don't have it. The fact is the 2GB of ram should allow a stock phone to reload things much less. If you want to look forward 6 months to a year, I think the difference will be potentially much larger when we start to see creative devs tweaking their kernels to really use this extra ram. This is a ground breaking hardware move. We haven't even really begun to see what is possible. Judging any of these based on stock software at release is pointless. Think about how much better other phones have gotten after a few OTA updates....this device, especially with the extra ram is really well equipped for a long time.

By the time any phone will actually use 2gb of ram, im sure most of us will have moved on to a new phone already. Of course having the extra ram is good for bragging rights, but does it actually mean anything? I'll say no, but im sure some will argue that.

they already make use of 1.1-1.2GB of ram out of the box running all stock software.......imagine if custom roms/kernels were available that make use of it....it's not far off....."by the time any phone will use" is closer than you think

This is good in theory but everyone on here is talking like we have been missing two gigs all this time in our phones. If you are coming to the S3 from a single core phone of course this is night and day. My SGSII has NEVER.....I repeat NEVER run out of memory lost track multitasking or had to close out multiple apps to make room for more.....how many apps does one need sitting in a suspended state?.....I have 5 or 6 apps open at any given time with PLENTY of room for more...sure the extra ram is nice to have, but its completely unnecessary ....dual cores with a gig of ram have NO problem doing heavy multitasking .....ask anyone running as SGSII or Gnex.
The extra ram in the S3 is there to offset the loss of quadcore....its a nice helping hand to the Krait chip but not necessary for everyday multitasking that the average person does.....I don't know what phones alot of you guys are coming from but from the sounds of these posts they were serious under achievers.

i think the reason you never saw your device running out of room is likely because the system knew how much memory it had to work with and was always adjusting things to accommodate as much memory....if the system had more memory available to it it can behave differently....it's not about "how many apps one needs in a suspended state", it's about "the more apps you can keep in a suspended state the quicker the apps will run for the user"
i know this isn't x86 and it's not windows, but the analogy still stands, consider Windows 7
if you build a pc using it with 2Gb of ram it will run just fine, it will use somewhere around 1Gb of ram sitting idle, using it for the prefetch cache to be ready to launch your most used apps while maintaining a safe amount of memory for sudden useage/overhead
if you upgrade that same pc to 4Gb of ram, it will use close to 2Gb at idle.....it's not quite linear as that but you can see a direct correlation between available memory and memory utilization
the Linux kernel behind android appears to work very similarly, it will keep the most called upon code in local memory so that it launches faster when next called upon. the more memory available to the kernel, the less time it can spend killing apps in order to maintain that same level of free memory for the unexpected execution of a new app
the more memory it has, if it is written/compiled to take advantage of it, the more potential for performance is there.
I would say the 2Gb of memory is more easily utilized than the additional redundant cores in the Exynos kit. I have been looking for some real data on Android and SMP but I know recently Intel made a rare public statement about how it is not ready for even dual core utilization. I don't think Intel would make such a specific claim without data. I don't think the Exynos users are really getting much good at all from the four cores other than synthetic benchmark scores and I think they could see more benefits down the road from more memory than redundant A9 older technology additional cores.
disclaimer: I am still learning about all this so if some smart guy comes along and sees something above that is not quite right....it's not because I am making this up....it's what I understand to be true based on reading.

You are pretty spot on for the most part....but the difference here lies in the amount of ram needed to cache applications and perform extended tasks.....the reason my GSII never runs out of memory is because it has plenty for any array of tasks. While caching 8 applications I use all day...and still have anywhere from 325 to 400 megs available for any other array tasks .....I just can't see where I would need more.
As for your earlier mention of custom roms.....this becomes even less necessary ....right now a stock GS3 is using over a gig.....that's because its loaded chock full O'carrier BS on top of all samsungs layers of bloat and BS "features"....you strip all that crap out and you have a 275mb OS and more ram than you will know what to do with.
Bloat is the only thing requiring this extra ram because its running at system level which is also why Sense stuffed a dagger in the H1X.
Performance for launching is helped greatly by the processor for anything not in ram and the threshold for my phone is 64mb....which means my phone will not start killing of apps until that's met.....I could not seem to hit it just messing around.

right on, yeah i agree it's overkill right now. I just think within the next two years, we will easily see multiple areas where having more is better than having less. I am thinking way outside the box but I am seeing visions of custom kernels that are doing some extreme caching, even running a VM type environment.....actually I am thinking of running Android and perhaps there will be an opportunity to run Windows RT or some desktop version of Linux simultaneously......something a device with even four cores and 1GB of ram would have a hard time doing.....and that's not to say it would run well on the S4 US version either, but it is certainly more suited for it

You are partially right. My sensation xl and my friends galaxy note works multitask pretty well with just 768mb and 1GB ram. But that was on Gingerbread. Once we upgraded to ICS multitasking suffers tremendously. He even blamed me for persuading him to do the update. For GB 1GB is enough. For ICS 1GB is not enough if you want the best multitasking experience.

Bigger Internal Memory vs Higher Processor

Heya folks....i read from many sources on the web saying that internal memory on android device will give better performance versus the external one. Some say that even the best class 10 micro sd will perform not as good as built in memory especially when loading HD games.
So I'm planning to buy android phone which has large built in memory, in this case i pick sony xperia TX, but now sony has launched a new device which is xperia SP. It has the qualcomm S4 pro and adreno 320 which is better compared to TX's S4 plus and adreno 225. But the problem is it has a small ammount of built in memory (about 5gb user available). Which one should i take?

Xperia TX!

In my view you should take the Xperia TX with the higher amount of builtin memory.
I'm shure that you won't need a high-end processor for your daily usage. It has also enough power for the most games available in google play.
And I can say that you don't hav a much fun if the internal memory is to low, especially if you're planning to play hd-games wich will probably need about one or two gig of memory
So in my view you really don't need the SXSp...
I hope this helpes you a bit,
icebeanpie
And sorry for my bad english - I'm from germany

You could also just get a HTC One or a Samsung GS4 wich hav both, big storage and a nice processor...

Bigger internal memory ruless...
I usually put huge data game on internal memory, it reduce lag n rendering time (trust me, I done compared it)... But I still have 32gb class 10sdcard to keep media like video,music n stored picture..
It suck to have generated 10 post just to tell how happy n thankfull iam for using a rom they make.

The most annoying problems with G3 explained

Firstly, let me apologize for my English and the lack of technical terminology in my vocabulary.
Secondly, a disclaimer: I do not own any Samsung phone. I think that my wife's LG G2 is the greatest phone in the world.
Let's get to the point...
Polish site PCLab has just published a detailed review of G3 (European model) with some astounding tests' results that might shed some light on all disturbing reports about problems with LG's new flagship device. And while Polish journalist praise the phone for its incredible design, great UI, decent camera, they are at the same time very disappointed with some serious software and hardware problems that G3 is suffering from. I have read tons of different reviews, but it's the first one that explains why this phone "lags", overheats etc.
Problem: POOR BENCHMARKS' RESULTS, LAGS
Some reasons:
1. It seems that RAM sticks (is that the correct word?) in G3 are worse in terms of quality than the ones from G2.
2. CPU management is set to deliberately lower clock rate and restrict maximum clock rate to one core only in most of the cases. And when all four cores are in use, CPU management does not allow them to work at maximum rate at all. It has some serious impact on UI operations as well and makes better chpset in G3 perform worse than Snapdragon 800 in G2.
3. The temperature. G3 has some serious problems with heat distribution. When the CPU is working for longer period of time, the clock rate is lowered to 1.5 GHz and (what's worse) GPU clock is being seriously restrained. For example, after several minutes GPU clock rate is slowered by 40% (from, say, 20 fps to 12 fps)! It's the worse throttling among all new flagships.
4. There's no trimming in system's internal memory. That's one of the most important causes of "lags".
5. The new UI has some problems with memory management. Sometimes while using few apps there is only 174 MB of 2 GB of memory avaible! And the only way to free memory is to restart the device.
And yes, this review also confirms problems with oversharpening of the text on G2 dispay. The reviewer says that it's the software issue (or rather: "LG's conscious marketing decision").
You can see all the screenshots from various tests here:
http://pclab.pl/art58419.html
I have no idea if these problems might be fixed with some software updates, but I really do hope so!

I've only read a little of it but one of the things that caught my eye is that they are complaining about having only small amount of free RAM. Another poster on here asked about this, RAM is used differently in Android as it is in Windows for example. Free RAM in Android is bad not to mention that the kernel is using around 25% of RAM as ZRAM which I believe is standard in 4.4 kernels! So the article in that point is wrong. I've also looked at the CPU usage on my phone and measured it against temperature. During normal use the temp is around 45-60degC and the CPU is not throttling its sitting at it max 2.5Ghz. I posted a screen shot of this on another thread. They may have a pre production model with early OS version.

OK, CPU V temp graphs of normal usage. CPU is spiking to 2.5Ghz, no throttling and temps are normal. RAM usage shows around 400MB free always. Totally normal for Android as I said it fills the RAM then kills apps as needed.

Are you sure about that?
Whenever I have less than 200MB RAM left, my homescreen redraws, opening/closing apps and browsing through the menus is slow.
Whenever I have more than 500MB left my phone is as snappy as the nexus 5.

Android fills RAM up as you open apps up and leaves the apps in the RAM so you can multitask. As soon as it needs more RAM for other apps it automatically kills the apps sitting in the RAM. Launchers have a big RAM footprint, you're better using a lightweight launcher such as Nova and using the "aggressive" setting which means it never gets killed and sits in the RAM permanently. If you look at your RAM usage whether you have 2gb or 3gb it will always be mostly full as that's how the kernel us handling its usage, its filling it up for multitasking. The article in the op states that the RAM is always mostly full, yes that's good as that's what its supposed to be doing.

This is because LG is trying to run a QHD display on the Snapdragon 801 chipset. The Snapdragon 805 is required to run a QHD to achieve the same performance level as the Snapdragon 800 running on a 1080p display
You can read about it here - http://www.anandtech.com/show/8035/qualcomm-snapdragon-805-performance-preview/3
Manhattan continues to be a very stressful test but the onscreen results are pretty interesting. Adreno 420 can drive a 2560 x 1440 display at the same frame rate that Adreno 330 could drive a 1080p display.

Trim is built in, yeah. The G3 does have issues and the S801is at its limit pushing the QHD display but with ROM and kernel optimization there's still more performance in the phone.

That is exactly what the reviewers says: when there was only 174 MB of free RAM the phone started to redraw homescreen and freeze. There was no way to get rid of this. Uninstalling apps and closing them did not help. One could only restart the device. The journalist claims that this software issue can be fixed with an update (if LG decides to release one).

Well, the reviewer also says that trimming at fixed moments (or while deleting files) is standard for Android, YET the test revealed that in system's memory of G3 there is no trimming. He is also surprised and says that the quality of this emmory (eMMC) is good, but no trim makes it laggy. (I hope I understood it correctly).

I also hope that it will be fixed. But so far there is no serious update. And it's been 5 (6?) weeks since Korean release. And, as far as I know, no other flagship device had such a serious problems. Can you imagine Z2 or S5 perform worse than Z1 or S4? And yet G3 with 801 (in some tests) performs worse than G2 with 800.

Use Xposed App Settings to set your Launcher as 'Resident'. Got rid of this issue for me.

The CPU almost always staying at 300mhz is the largest issue I have with the phone - its not a huge issue, more of an annoyance. I am guessing its been done to maximise battery life and reduce heat.
I don't think this is due to thermal throttling, but if I am wrong please correct me - has anyone had success with turning the throttling off?

It looks like as an author of this article (I completely did not expect to find this link here ) I need to clarify few things.

I've only read a little of it but one of the things that caught my eye is that they are complaining about having only small amount of free RAM. Another poster on here asked about this, RAM is used differently in Android as it is in Windows for example. Free RAM in Android is bad not to mention that the kernel is using around 25% of RAM as ZRAM which I believe is standard in 4.4 kernels! So the article in that point is wrong. I've also looked at the CPU usage on my phone and measured it against temperature. During normal use the temp is around 45-60degC and the CPU is not throttling its sitting at it max 2.5Ghz. I posted a screen shot of this on another thread. They may have a pre production model with early OS version.

I'm well aware that "RAM not in use is wasted RAM" and that Android keeps a lot of things in memory to make everything faster, not slower. When my G3 has ~300-400 MB of free memory, everything works fine, but after some time it fills up and there is no room form launcher, more than 1 tab in Chrome and so on. It clearly is some problem with memory management and as an long-time Nexus user I'd rather say it's a bug, not a feature

Claim that every smartphone with Android 4.3 or newer allways has TRIM because it is "built-in" is not entirely true. There are different ways of supporting TRIM. Most common one is ext4 filesystem with discard flag active (ext4 without discard does not TRIM automatically), which was used even before ANdroid 4.3. Motorola has F2FS filesystem, which is optimized for NAND storage and has garbage collector allways active. There is also "Nexus way" TRIM with garbage collection demon running in background. In G3 data partition is ext4 without discard flag and in system logs there are no signs of any TRIM commands running in background, so AFAIK there is no TRIM support in G3 at the moment, or I have strange preproduction sample. The best way of checking that would be rooting G3 and running fstrim() manualy, but i can't do that with my review sample.

That's not the whole storry. Yes, highier ressolution is part of it, but it looks like G3 has very small thermal headroom and during longer heavy GPU load it's clocks get cut by ~40%. (unfortunately i can't paste links in my posts yet). During 30 minutes long GFXBench loop, after ~15 minutes GPU throtling kicks in and this Snapdragon 801 gets much slower, than Snapdragon. Yes, allmost every new smartphone with S800/S801 throttles in such situations, but G3's case is most extreme one I've ever seen.

All these reviews are annoying. The device just came out. A lot of this can be fixed via an update.

And selling beta hardware with beta software for full price isn't annoying?
I'll try to figure out with Polish LG representatives if these problems are typical only for this specific sample, or it's something more common. At the moment my opinion is that G3 is very cool phone if your typical usage scenarios do not hit the "heat wall", but if they do this phone gets pretty annoying (backlight dimming, heavy GPU throttling and I've even managed to overheat camera so it stopped recording 4K video after 2 minutes 15 seconds).a
Unfortunately my english is not as good as I'd like it to be, but I hope I explained few things a bit.

Thank you, bedlamite!
Could you tell us if any of these issues might be fixed with some software updates?

Thanks for the clarification.
Everytime I open my multitasking I have a look at my RAM bar and its always between 350-400mb so I don't think I have the problem you're having.
I have rooted and FSTRIM runs fine on my G3...
I do agree with you though, there is issues.

Guys, the 801 is more than capable of handling QHD, the problem is heating, when the phone gets hot there's aggressive cpu throttling by LG software. The 805 is more powerful with less heat so that's why it more suitable for QHD devices. Same goes to the screen not so bright too much heat.

*OFFTOPIC*
Guys please put those high-res pictures in spoilers! They are totally overloading this thread.

Thank you.

No TRIMM??
Is this serious?
I've always feared that most manufacturers don't include TRIMM or take it away from their phones because that way the phone slows down and forces the consumers to upgrade to a newer one.

[Q] Gaming performance

hey guys
I was planing to buy this phone so I have a question from those who are already using it
how is the gaming performance on this phone in comparison with Xperia z5 compact?!
---
I mean, I know there is huge difference between adreno 430 and 510 which is midrange but how is it in real life gaming!
if anyone have tested some games like asphalt 8 or dead trigger 2 please review here
btw I just want to know the performance because this screen size is not for gaming anyway...
thank you

Adreno 510 is better than the 430..dont see only gigaflops,...the snapdragon 810 is hot and throttling..a lot

http://www.androidauthority.com/snapdragon-652-vs-802-whats-difference-686684/
430 got double faster but it will throttling down bcoz of hot at the end the speed would be about the same.

so it means 510 aint that good it's just that 430 becomes the same after some minutes, so whats the conclusion? does Xperia X compact perform good in real life gaming or not?
and by good I mean no lag on high quality!

Overall XC must be faster with 3GB ram. I'm stick with Z5c bcoz I want more developments.

@op the xperia xc will play the titles you mentioned, it will play all new games fine including real racing 3. and it will do it very energy efficient too ie. less battery use and more play. =) the cpu cores cortex A72 over A57 (although there are only 2xA72+4xA53 they are on par with 4xA57+4x53) are also a step up since they again are much more efficient per energy used which is a factor many forgets, it might score the same benchmark but if the cpu/gpu only uses half the energy its a big improvement in my eyes. the 5xx is also the first chipset to officially support Vulcan (next opengl) although the 430 in theory should be able to support it too. I own both phones, love the z5c but the XC is imho a step up and better phone overall. everything; if it is games or everyday use is just more fluent which probably is contributed by the extra GB ram and the added efficiency and scaling of the SoC. the camera, and fingerprint reader are insanely fast too.
edit: you can see some game performance in this review, he also talks abit about it, which is the same as my experience; the game might load a little slower but once loaded it runs great.

Disable Ram Expansion for a boost in performance

Since android 13 upgrade (wasn't amazing before but certainly was much worse since 13) i've been getting really inconsistent gaming performance.
But not in a way that dipped the FPS -- as system status in games was showing good fps but the game felt jittery / laggy and overall very inconsistent.
Been driving me nuts to the point where i'd almost stopped gaming on it because it was so disappointing. Was going to send my phone into Oppo for warranty claim it was that bad.
Decided to try and be a little more analytical about it and look at the individual element scores on antutu and i saw my RAM performance was pretty bad.
Played with a few settings but nothing seemed to do much until i remember about Ram expansion (using storage as back-fill ram) and tried turning that off (reboot after).
Well, my antutu score has gone from 720k to 806k in normal mode and ~830k in performance mode (since antutu isn't recognised as a game to automatically do that)
Games are now totally smooth again, no lag. It's almost like a new phone.
My thoughts are that the android implementation of this either doesn't properly keep active high-demand stuff from swapping into this expanded ram or that android just doesn't handle the scheduling of this properly.
Either way -- for me its way more valuable turned off for overall performance and stability.

Did the same already some time ago, can not understand why in the first place. that a phone with this huge amount of ram already factory installed, would need another 3 GB of ram.

Technically it doesn't i guess... maybe for a ram constrained phone ... but then if it's costing performance cos of a bad implementation then it's a lose-lose position.
My phone is noticeably more consistent on performance with this feature disabled.
