[Q] Nexus 7 Capabilities - Nexus 7 Q&A, Help & Troubleshooting

I've been searching in vain for some hard facts about what the Nexus can/can't do. I can't see, for example:
1) what the multitouch is like. Does it do proper independent tracking of 2 fingers? 10?
ie android.hardware.touchscreen.multitouch/.distinct/jazzhand
2) usb - does it support usb storage or not (via otg).
I can read plenty of answers, but I'm sort of fussy in that I'd like the correct answers, not just the guesses of some user. Do any developers have Nexus 7s yet?

I'd be terribly surprised if it didn't support 10 point multi touch. Even my Samsung Galaxy Tab, the very first Android tablet, supports 10 points. The USB OTG question has already been answered in the general section (the answer is yes with root and an app).

Not complaining, but why do tablets/phones have up to 10 multitouch points?
I mean, when will you use, at most, more than 3 fingers?

Onscreen pianos would need up to 10. Two pinch/stretches would need 4. Multiplayer games might need a couple of fingers for each player and on larger screens you could have 4 simultaneous players.
I want to know because I started to write and then abandoned a game on my HTC Desire because it could only track a single finger reliably.

It supports 10 fingers "a responsive 10-finger multi-touch screen": http://www.asus.com/Tablet/Nexus/Nexus_7/

porting!!!!!

Theoretically if i knew specific specs of an iphone could i somehow port win mo to an iphone? One of the main reasons i would even bring this up is the ability of the multi-touch and the larger processor (i wanna say 720mHz)

Well, theoretically you could build your own phone that's 50 times faster than an iPhone, with 10 times the resolution and 100 times the storage. And ran WinMacOSXubuntuDos, all with neural interfacing - no touch required.
Anything's possible theoretically.

Seriously now, guys are having a hard ass time writing drivers for the video issues on the MSM7200 chipset devices. How do you realistically think porting the entire WM OS to a foreign device that you will have no device reference info to is possible. Theoretically yeah I guess, but realistically, well you know the rest of the sentence....
glad everyone is on the same page hahaha....... i must say though when i heard phones would be coming out with gHz chipsets now..... does anyone know exactly how the multi touch works, is it software or hardware that makes the difference. because the whole "finger only sensitive screen" isn't really that..... it responds to anything that is thicker as an input, so it probably has something to do with a lock on a certain range of size..... since all programs are input output and touch flow is now modifyable is there a way to write software or a driver for the multitouch?????
sorry to seem iintreged by the iphone, really i hate it and personally think the only real "new" thing it produced with the multi touch on a handheld devise. I mostly just don't like apple because they Ruin everything they create by being overprotective of there stuff..... thats my two cents for the day though......
Food for thought, is there an exchange rate on your thoughts or something cause people say a penny for your thoughts but i've always given my 2 cents

I have been told that multitouch requires a whole different type of screen.
I have aslo been told that there is a possibility that WM7 once released will be able to support multitouch; however, you will not be able to just put WM7 on any phone and have multitouch because our current screens cannot support it. There will have to be completely new devices.
I wonder if the HTC Touch HD will be able to support it though.
i imagine one day our ppc will replace a p4 desktop able to output xvid video quality to tv
able to dl large gb files over the air at t1 speed and watch local tv anywhere around the world.

good refrence hambola
i understands how the touch screens differ now, but if there is a way to program "actions" such as swiping a finger is there not also a way the write a piece of software that could then some how measure the size of the objet pressing on it? can we better control the "smartness" of our screens?
i no the type of screen our htc phone can only register one point because of the way it litterallly registers though the contact of two plates and just gets confused by a large object, but is there a way to assign an object to that confusion?
I think this should be off-topic....
yeah probably but i really have no idea how to move it... and itskinda development and hacking or atleast about it

Update to windows mobile 6.5 and 7

Hello Xda
i am wondering are we can able to upgrade to windows mobile 6.5 in the future and windows mobile 7 too.
also can we will be able to use multi touch function on hd device?
Well on past models HTC have released new ROMs with newer version of WM, so you would think they would release new updated ROMs for the HD.
Unless they have another new phone on the horizon! You would think they would wanna sell 1 or 2 HD's first though before they release another 'high end' handset.

Yer was very close, I heard mixed reviews of the Diamond/Pro so held of upgrading, then the HD popped up on the HTC website so waited for the HD instead!
winmo 7 is said to have hardware requirement of 256MB ROM for the OS. so should be fine.
WinMo 6.5 will probably be less than 256MB ROM too so all go there too.
TOUCH HD should be well future-proofed for WinMo updates (official or otherwise), and then there's the possibility of Android too......
I think and hope that they will release at least an update to winmo 6.5 But I also think you shouldn't hope for Multitouch! If i'm not totally wrong the HD use a resisitiv Touchscreen and they are all not cabable of Multitouch, doesn't matter which Firmware is running
There is supposed to be a pre-WM7 release, not sure what else is included but supposedly it will have a better version of the IE browser.
I imagine this may depends on how much WM7 will be a change and needs adjustment from HTC. Like... what will be the touch 3D layer then ?
My bet is, the more we are expecting from WM7 as a breaktthrough in the series the less me may use it on this version of the Touch HD.

Actually, correct me if I'm wrong here, but resistive technology is able to detect multiple touches - and even laptop trackpads can too, it's just that there's never been any software developed for it, and the operating system has just been hard coded to ignore multiple touch points and averaged them out to somewhere in the middle of where touched.It's pretty much a case of trackpad and touchscreen designers going "hmm what about if someone touches with two points at the same time? Ah well, there's no reason for doing that, let's just average it out"
Now, more realistically speaking, what exactly is the benefit of multi-touch on a mobile operating system? Pinch zooming? The zoom bar on Opera seems pretty simple and actually easier to use to me! Anything else? New Macbooks use gestures for Expose (no use for that on a mobile), two finger scrolling (about the only day-to-day useful feature, but again useless on a mobile device with finger scrolling anyway!) Two finger rotating maybe (um, accelerometer does that for you!) so anybody got any more suggestions for making this gimmick actually useable on a portable device that can't do it better already?
How can you play an instrument like a keyboard without multi touch!
While such a functionality might be an intesting one, it also seems like a step backwards in certain aspects.
Single handed operation is one of the essential aspects of mobile phones.

No correction needed, this is 100% true. Touchscreens do not register clicks, or anything similar, the screen itself is nothing but a sensor. The screen sensor layer on the HD screen registers any surface part of the screen on which the pressure exceeds a given threshold and the output is translated by a driver into anything the OS uses for manipulation. Thus, theoretically, ANY touchscreen device can be multitouch.

Many of the more objective iPhone users have indicated that multitouch should not be overrated. It is nice for picture viewing, but in practical terms such as with a browser, it can be frustrating to see people zooming in to 100% with a swift doubletap while the iPhone users themselves are having to place two fingers on the screen, prevent accidentally using your nails, and having to squeeze/pinch until the page looks right.
BUT... I for one believe that more natural forms of input, i.e. a Keyboard, REQUIRES multitouch to function 100% intuitively. You simply do not need to release your finger from one key in order to press another, and a singletouch screen does require this. This causes lots of mistakes when typing too fast, you have to be over-articulate while typing.
Then again, I see most iPhone users typing with one thumb even when sitting down and holding the phone with both hands, because it's their first smartphone Not fair... WinMo pro's should have received this years ago
Oops I am straying from objectivity here...

from the youtube video info:

Skin name: Windows Mobile 7 i3
(i3 = 3 interface)
Skin version: QVGA
was it really that hard to read? the info was RIGHT THERE.
where to find
Out of curiosity where do we find this skin? all I can find is that youtube video. At the moment I'm getting a little bored with my current ROM and right now am looking for a new replacement look on my vogue.

Just another confirmation of this. Synaptics, the maker of most touchpads for laptops, released driver updates for laptops to include multi-touch pinching, gestures, zooming, and Chiral(circular) scrolling - These were for touchpads that could previous only do what WinMo does with multiple touches.
So, as everyone said, you're right. If the manufacturers wanted to, they *could* give us multi-touch, but WinMo doesn't have an implementation of that anyway so it's useless.

specially for hd which has almost no hardware buttons multitouch would be a nice feature videogame-wise... like shooting while running or steering while accelerating...

The hardware is there. There's just no software capable of it yet. I'd be suprised if we don't get full multi-touch recognition apps at some point. (For people that don't understand what that last sentance actually means, please note that when I say full multi-touch I do not mean more than 1. I mean as many as you want.)

scilor.com/hd2-leo-real-multitouch.html
found this, but i can't get it to actually respond to multiple fingers
You might have to soft reset to get it to work. It won't recognize more than two fingers as documented elsewhere on here or on his site, guess he never got around to doing a lower-level hook.
Or is there a way to upgrade hd2 clearpad 2000 to 3000?
According to the Visual Multitouch Test App from the Android market, I can only use up to two points. I don't know if this is a restriction caused by the Android port, or if the HD2's digitizer/screen can only support two points at once.

Atrix 4G- just two fingers multi touch?

I just tested the multitouch capabilities of the Atrix. It only registered two fingers? wow I have expected that it will recognize at least 4.....I don't play games on my phone so I don't worry too much but still it leaves a bitter taste...
You can't really use more than 2 fingers on a 4" screen anyway unless you have tiny hands.
Why would you ever need 4 point multitouch on the atrix to begin with... I mean of all the things to complain about this is the lame...

First of all. I wasn't complaining. I just wanted to test how accurate the multitouch is because I am a former N1 user and the multitouch sucked. It was more by curiosity that I tried 3 fingers. I had also a Nexus S and a MT4G and they could register several fingers. I thought that all newer touch sensors were multi finger enabled...
BTW I like my Atrix very much and the screen responsiveness is better than on my HTC devices that I had.
from the build.prop file, it says 2 max touches.
I tried to change the value to 4 but it still would only register 2.
wierd my Nexus S allowed 5
and htc desire HD allowed 4
i think newer screens would allow more, not that it matters
just curious
Is by brand is not HTC so don't expect the same I guess it does suck tho , oh well
I looked at the fixit site and they say it is the same sensor as in the Nexus S: Atmel mXT224. But this beast should have unlimited touch according to the manufacturer. Interesting maybe it is disabled software wise.
As a former N1 user, this touch issue is not important. What is important is it registers two independent touches and never confuses them.
Why is this important? Virtual game joystick and buttons. You will never use more than two touches for that.
Yes there are a few games or apps that can do more than two touches and it is disappointing to not have that enabled. But we will almost never notice this.

This has already been proven for the Atrix (that it treats multitouch correctly); read about it a few days ago on this very forum.
http://forum.xda-developers.com/showpost.php?p=11540136&postcount=56
The Atrix has the same ATMEL multitouch sensor as the Nexus S, EVO, etc. So we know it can register at least 5 screen inputs at once. The apps you are using to test the multitouch input simply does not support the device (yet), and will need to be updated in order to for this phone to register multiple inputs beyond 2. This is simply a case of outdated software on new hardware.

The EVO would not register more than two touch points while operating on the stock kernel - and it was shown after rooting and unlocking the bootloader that there were two different touch panels - one that could do three points and one that could do 5.
So hopefully the OE kernel enables the use of the max number of touch points supported by the screen and it is just a matter of outdated software.

http://www.tgdaily.com/business-and...-back-at-motorola-with-multitouch-patent-suit
Apple, Google and device makers have been embroiled in patent lawsuits since the first Android devices were being made. It still continues. If folks recall, there was huge controversy when I think the original Droid (or was it even earlier, the G1 maybe?) came out and didn't have multitouch in the US, but the international version did. This is why and it continues to be an issue.
What are you talking about... The ATT captivate with the froyo ROM does 5 fingers...
Galaxy s has 5 touch

multitouch screen

I just did a test on the Thrive screen. It can only sense 4 simultaneous touch while other tablets like the galaxy can do up to 10 touches. So I was wondering if the number of simultaneous touch on the thrive is hardware limited or it is possible to increase the number of touches in future kernal hacks?
Thx
i have up to five multitouch on my thrive, and confirmed into playing fruit ninja and see up to five swipes at a time. And to answer your question, a hack won't change the multitouch capabilities of the device.
thanks for the quick reply.
Now how come you can get 5 touches while I m only getting 4? Are there different hardware variations in production? I hv the 16Gb version. What numbers is everyone else getting?

This actually isn't always true. Take the Droid Incredible for example. By default, its multitouch is limited to two points. But with a modified kernel you can get up to 10. It all depends on if it's a software or hardware limitation.
Sent from my ADR6300 using XDA App
Also receiving only 4 touches, tried this on Fruit Ninja, stock keyboard, Hacker's keyboard and Better Keyboard.
