I Think I May have found the cause of the otherwise apparently 'random' freezes/hangs and total lack of touch sensitivity.
Basically, In my case at least, It Is the G-sensor/accelerometer.
I have been noticing increasing numbers of these freezes on Mattc 1.5 Froyo, Mainly in Landscape, Mainly in games.
TEST:
I installed 'Iron Sight' Game. (If theory is right then you should be able to use any landscape game, but please try Iron sight if possible.)
I Ran the game and it switched to landscape,
SO I PHYSICALLY TURNED MY HD2 TO LANDSCAPE.
THIS IS WHERE THE FREEZING AND LAGGING BEGAN!
On the Main menu found it difficult to press any options.
When I did manage to start a Game The control buttons were hard to press and the game was unplayable because screen sensitivity was just not there most of the game.
I Then Physically turned the HD2 around and Back to Portrait orientation, AND ALTHOUGH THE SCREEN ORIENTATION STAYED IN LANDSCAPE I DID NOT EXPERIENCE ONE SINGLE LAG OR FREEZE.
BUTTON PRESSES WERE RESPONSIVE TO TOUCH AT ALL TIMES FOR AT LEAST 15 MINUTES!
HERES WHERE IT GETS MORE INTERESTING....
I Then Turned the HD2 back around to landscape again and the Problems IMMEDIATELY RETURNED.
I THEN HELD THE PHONE VERY STILL IN LANDSCAPE AND AFTER A FEW SECONDS THE PROBLEMS/LAG/FREEZES DISSAPEARED AGAIN!!!
TESTED REPEATEDLY!
IN LANDSCAPE AS SOON AS THERE IS ANY PHYSICAL MOVEMENT, THE GAME FREEZES, BUT IF I KEEP IT STILL THE GAME RESPONDS PERFECTLY WITHOUT HESITATION.
Can some of you please test this theory?
A cradle/Dock would be handy for testing but it is possible to keep the phone still enough in-hand in my tests.
Use the game "Iron Sight" where possible, but use other games/apps too if you have time or inclination
Post the results below ( with logs where possible ?) Please.
Note:
After discovering the above, I did a search on XDA and found that a member called 'Hinky' and touched on this but I think I have narrowed it down.... I think
Please test and confirm (or debunk lol).
Thanks.

Yes this is something that the devs have been discussing. It does seem that the freeze issue is in fact related to the g sensor. I don't know if anyone is working on it at this time but I believe Cotulla will try to sort it out for his September release

Lol keep with the testing though I didn't figure that much out
Hmmm this is def the prob for my touch screen issues. I tested a bit using the latest mattc Leo + Froyo w/Sense 1.5 version, with latest FULLRAM. I found that while on the sense home screen if I hold the phone out in front of me either landscape and portrait it's ok, and I can do whatever I want at full speed no lag at all. THEN if I lay the phone flat, It freezes. I did this like 20+ times and every time It would freeze whether I was playing a game or reading an email.
This also happen to me. Using Mattc 1.5 Froyo, it happens when using internet browser. The screen will freeze or not response right after i turn from Portrait to Landscape or sometimes have to wait for few seconds. I have to turn my device from Landscape to Portrait, and back to Landscape again, then the screen responses back to normal. This also happens in Copilot app when using in Landscape mode.
I turned off the screen rotation
What I did since i installed my ROM with 380mb ram is to turn off all screen rotation settings, so far so good, I haven't notice any freeze or lag so far in any application or while waking the device up, I used to have it and I hate it, I almost went back to Winmo!!.

This was the first thing i tried but strangely it made no difference.
anyone know how to totally disable the g-sensor?
doesnt have any of the mentioned problems...
iron sight lite runs the same for me when i hold the phone portrait or LS...
have no bad screen sens while holding LS...
running mattc 1.5 with the default zimage...

Please tell me....
Did you fresh install 1.5 or upgrade 1.4>1.5?
I had quite a few freezes on 1.4.
Then I upgraded to 1.5 and kept my apps etc from 1.4.
I HARDLY HAD ANY FREEZES AT ALL
Then I did a fresh install of 1.5 and started getting LOTS of freezes.
i did a fresh install.
i deleted all android files on my sd card and extracted the new build to a new made "Android" folder...
i use xanny roms, and i still have the robovoice problem, so i can´t use android daily...
i noticed on all android builds ive tried sofar, that the polling interval of the gsensor is very bad/small. U can see it when u go to calibrate the gsensor, the bubbles move very slowly...
this is not a big thing when u only use the gsenor to turn screen to LS, but it is essential to play games using the sensor...

Lol, no worries I'm glad that you pointed it out. This was actually one of those really useful threads and the kind of thing that the developers are looking for. I am not a dev but I speak with them pretty regularly when the same issue are pointed out time and time again by those who do not read the threads. This was something that has not been talk about here so I appreciate your well thought post and the information that you provided
I was just a step before creating a new thread about it when I saw this one.
This is definitely one of the things that are really pissing me off using Android.
Furthermore, I did tests on this issue for quite long to doubt that it's an autorotation related issue. Maybe it has something to do with the g-sensor, but it still would happen randomly even trying not to move the phone at all. I noticed that the problem wouldnt appear that often when decreasing the polling interval of set cpu and same time increasing the min. freq. to 380, but still, it DOES happen.
I'd really appreciate any statement on this, developer side of course.
I have the occasional screen freeze on landscape, but not very often using froyostone.

Cheers for that ^
+1 for the Gsensor polling intervals seeming very slow.
THIS CAN BE SEEN VERY CLEARLY USING THE 'VR TUNNEL' LIVE WALLPAPER.
Here the cubes move smoothly at a good fps while the tunnel moves around at what appears to be 4/5 fps.

For a moment there, before I found out it was a known issue... I thought I had discovered the Androids very own penicilin or something equally as important... but as usual I was behind the times lol.

Possibly not related to autorotation per-se, but...
With Autorotation disabled... If I turn my phone on its side (with volume buttons pointing towards floor) I still experience freezes on my home screen or anywhere else for that matter.
Plus I have found that holding the phone VERY still in any position seems to eliminate 'ALL' freezing and lagging problems.
Do the G-sensor and the Dgital compass 'interlink' or communicate in any way? Is it possible that the screwed up compass output is screwing with the g-sensor output?
I ask this because the game 'hungry shark' thought that my phone was flat whent the usb port was pointed down towards the floor.
Dont know if that makes sense but for me it seems like the g-sensor is fubar as well as the digital compass.

Well ofc, it wouldn't freeze when it's COMPLETELY hold still, but I guess that shouldn't be the point of daily usage.
Now when it comes to spontaneous outside actions, you are trying to pick up a call using touchscreen cuz ur used to it or trying to shoot out a text in hurry, and your device will just go sleep for some time. I mean, how'd you hold still if you're moving (fast)?
If you ask me thats pretty much a major bug, not to forget the 3g data thing. I'm not moaning around, just want to attain more focus on this. I notice people losing themselves in some benchmark trolling - just time waste.
There is already a thread for that (walking dead)
Just found a possible solution, please repport if it is better for you too :
- boot windows mobile, calibrate the g-sensor in settings (i did it 2 or 3 times, but i don't think its important)
- do a proper shutdown of wm
- restart wm + android

After disabling "Auto-rotate screen" I haven't had a freeze yet, so good so far.
Has anyone run into issues w/touch on this device periodically?
I've been having problems with mine from time to time where a touch is registered in the wrong location... like very wrong, I notice this most often when looking through menus in the system settings.
I fight with scrolling properly in a few diff apps. One in particular is pocket informant. Some times I also have trouble switching home screens and the transition starts to twitch when it hits about half screen then ultimately returns to the screen I'm trying to move away from.
If you would like a video I can try to capture it
Is this common or should I start an RMA and get a fresh new A7 on the way?
I've had this problem sometimes. I think it's because the screen is probably low quality or something is.
Ive also noticed that if I bring it too close to my face to see the side buttons in the dark, my breath on the screen makes things jump around spastically.

My screen has been touchy as well
I have tried to install racing games on my Adam lately, but there is a major problem. The screen is in landscape, but the steering (g-sensor) is acting like the device is in portrait mode.
Have anyone else experienced this problem and maybe found a solution?
No configuration in the settings for the game?
Nope, unfortunately enough
It's a known issue.
A known issue with certain games, not the Adam itself. This would also affect most other tablets including the Xoom and Transformer.
Some games are hardcoded with phones in mind, and their default setup is portrait, not landscape. As time goes on, Android game devs will likely correct these issues (and in many cases they have, in the last few months). But it will probably be a long time before it's 100%.
Has anyone had any issues with the gyroscope? Is there anyway to recalibrate it?
When playing games I notice it veers to the left, for example temple run on a flat surface, character is running along left wall. I guess this could be an app issue.
Anyone else experience this?
Thanks
Does it use the accelerometer at all? If so, completely close the app, hold the tablet in the perfect "Centered" position, and re-launch. This will re-calibrate the app to the accelerometer.
I get an issue in Modern Combat 3 were within about a minute of play the character ends up looking at the ceiling very annoying. Tried recalibrating in app etc. but to no avail. Anybody else experiencing this?
Similar issue, I have to hold my device completely straight up before the screen rotates. Problem with the gyroscope maybe? But when I play games like Rip Tide GP, it works perfectly, senses every single movement, no matter how slight. I'd hate to have to return it, since this unit has no other issues .

I'm having the same issue!
Everything works fine except the screen rotation, which I have to hold the device completely vertical (or toward me) to make it rotates.
In games, it seems to work fine though.
I have no other issues, and would hate to return it back too.
Is there anything we can do to calibrate this?

Ditto here.
My case with stand sits at angle of 15-20 and when a new app is launched it fails to detect that it should be in Landscape mode?
Here's a demo of the issue:
http://www.youtube.com/watch?v=IIYzn54uN9Y
I had to recalibrate my compass to make it work right. There are instructions on youtube -- open an app that uses compass, etc. and spin it three times around on three different axes.
Don't know why, but some apps seem to have compass issues when others do not.

But it's not a compass issue. I downloaded a compass app for my N7, it works perfectly. Just can't get the screen to rotate unless it's held at a perfectly vertical angle.
I don't know if this is just me, but I'm so used to just kinda giving the device a little shake to point the gyro in the right direction (for landscape or portrait), so I haven't noticed anything weird.

I also have this. I've gotten used to the fact that I need to just quickly hold ot vertical. On a positive, I find my phone is too sensitive, and when I lay it flat on the table it sometimes switches orientation when I don't want it to, but obviously my Nexus 7 does not have this 'issue'.
I'd say mine rotates automatically at anything beyond say 30-40' from horizontal and while very slowly tilting it to that angle. I definitely do not have to bring it to anything near 90' for this to happen. I am not sure that I'd call it not rotating at 15-20' an issue other than one of sensitivity, and if it becomes overly sensitive it has a tendency to flip at the smallest movement/vibration, which occurs in a number of phones on different roms.
if anyone else is still having this problem I figured out how to fix it. Close the app/ game, then restart with tablet flat on a table or surface. That should reset it at center.
I have been having this problem since day 1. In temple run if i hold my nexus straight he runs down the right wall, i have to hold it about 25-30 degrees to the left to center it. Other games and apps exhibit the same problem. I have yet to find a solution. I have tried all the tips suggested here and even flashed back to stock. No luck yet.
I had an issue where the gyroscope endlessly turns towards one direction. Going to erase the tablet and see if that fixes the issue. Will report soon.
--update
erase and reset resolved the issue for me
I got my new one today (already have one with bad screen) and it has this problem.
Have to hold the tab directly facing me to rotate, games veering off to the right etc.
Calibrating with compass makes everything work until I remove it, then all screwed up again.
Been on to Google for a replacement
i'm developing a 3d augmented reality app and i tried it on my nexus 7 and after a few other apps that i tried that use the gyro it looks like google swapped the x and y axis or something. so it's not really a hardware error, but more on the software side...
edit: or maybe not. but there's definitely something going on with the gyro.
edit2: on further research it seems that the timestamp of the gyroscope sensor is broken, somehow i end up always getting the same timestamp. on my other android devices (galaxy nexus and galaxy s 2) this is not the case. if this is true (and my findings are correct) then this is definitely a bug that needs to be filed to google. can some other developer confirm this?
Hi,
I just started having this problem :crying: :crying: very sad with it.
It worked perfect since I received it a few days ago, then I locked (on the top bar) to use in an app and after I unlocked it it stopped working.
The behavior/test goes as follows:
- on the home screen, click on Chrome (or any other app that is supposed to rotate freely)
- turn landscape CCW, the app turns
- turn it back to portrait, the app does not turn
- back to home screen, open the app again
- opens in portrait
- turn landscape CW, the app goes landscape but upside-down (to be viewed as if it was turned CCW)
- tries rotating the app, it doesn't ever rotate again.
I would hate having to return it, but if it stays like that, I don't have other option.
------
edit:
I've just checked for games that uses the gyro:
Temple Run: the character is always on the right-hand side of the screen.
Highway Rider: although it's possible to turn the moto left, if I center the screen it will go to the right hand side
that's it,
just gave back to Carphone Warehouse (UK) and now I have to patiently wait for them to receive a new one so I can go pick it up.
I installed this https://play.google.com/store/apps/details?id=imoblife.androidsensorbox app that left me without any questions that the accelerometer was not working horizontally on the screen (if you holding in portrait) :crying:
let's just hope that the replacement doesn't have any of the faults that we've been reading around the forum.
I found a "workaround". I installed the "Compass" application from Google Play and use the "Calibrate" option... and it solved the problem.
However, I need to re-do the same steps when I shut down and start my tablet again.
That's the best I found so far...
There is an app called GPS Status & Toolbox https://play.google.com/store/apps/details?id=com.eclipsim.gpsstatus2&feature=search_result
It has a calibration tool and I had to run it a few times but once it got things working, it did stay that way even after shutting down the Nexus 7.
It even stayed that way after removing the app altogether but after altering the DPI to try tablet mode, it knocked the gyro off again so had to reinstall the app.
Such things really are just workarounds though and I certainly wouldn't consider keeping the device and having to keep messing like that.
Fortunately, my replacement has a perfectly working gyro.
OK, so here's my problem. I recently returned my nexus 7 for a newer production date build because I had a horrible touch screen. I updated the new one and had missed touches/sticky keys but when I unlocked it to apply sfhub's fix it wiped everything and the problem is gone (maybe a bad upgrade install?) Every once in awhile it feels like it's still missing a touch. Like once every couple hours. I've noticed that the touch screen is very sensitive and if I move my finger a little bit while touching it registers as a swipe I guess. Is there a way to see if it's really not seeing the touch or registering as something different? There are no sticky keys whatsoever and multi-touch seems to work fine in a case or out. Does anyone else see this with theirs?

Enable developer options and see the touches
You can test/verify the touches by enabling the developer options on the Nexus.
To do this, go to settings, go down to "About tablet", and then down again to the build number. Tap the build number information ca. 5 times (5 to 10? after a few taps you will see an info sign about how many times you still have to tap), this enables the developer mode.
In the settings menu there should be now a new item, Developer options (just before the About tablet). In the developer options check the box named "Pointer location".
Now when you touch the screen, with one or more fingers, you can see a screen overlay with coordinates and axles showing where the device sees your touches.
I have the touchscreen problem with missing and sticky touches and pinch and twist problems, the whole menu. For example, using google maps or writing emails is a pain in the ass because of these touchscreen issues.
On my device once I enable the "show the pointer location" -feature, I can clearly see that the device registers the touches right, but it behaves differently from the touches.
According to this I see, at least on my device, this more as a software than a hardware problem, and it looks that the problem is maybe even on a higher API level, which is IMO a good thing, because it _might_ be fixed with a firmware update. The question is, why Google hasn't done this yet, as the issue has been there around the world for a while, and there have already been a couple of updates (Q & R, or even more?) which haven't fixed the problems.
It would be interesting to hear reports of other devices. Test and report!

Yeah i feel the same too. I think the problem is software/drivers related than hardware and i dunno if there is a "perfect" device out there at all. I feel many casual users are simply not experiencing it. What i find odd is that, it always feels better after a reboot and things start to deteriorate from there. Almost like memory is not being released properly and there's some stucked process being stacked etc etc. Personally i find that eliminating the use of Chrome entirely has worked better for me. Am using only Dolphin now and it's been going very well so far.
The latest touchmark results shows there is a high latency in the Nexus 7 2013 model. It also indicates that it could be due to frequency of CPU polling for touches with a combination of other things in GPU too. IMO i think the high DPI on the screen and the handling of the quadcore processor might require some tweaking to get it perfect. There seems to be too much latencies and perhaps the missed touches / stuck touches are due to a combination of problems in the code with regards to touch events handling. Oh well, regardless i think they need a taskforce behind it to resolve it.

Thanks lomonic, an interesting link.
I had the former/original Nexus 7 (until my oldest daughter accidentally dropped it in May), and it had no touchscreen issues, at least nothing as bad compared to my new Nexus 7 (2013 model). Yes, it lagged sometimes, as does also my Nexus 4 (mostly noticeable when you slide down the notification menu or open the open applications list), but it had no similar problems with the precision of the touchscreen of the new Nexus 7.
I just tried to reboot the device and also noticed the touchscreen performing a bit better. Though, the problem came back in no time, and after a couple of minutes using Google Maps was the same mess as before. Twisting/rotating the map with two fingers results to pinching/zooming and the map centers somewhere else you want it to. Also in Chrome zooming and scrolling doesn't work as expected, and selecting text is also problematic. Using the keyboard might get you a sticky backspace, which is somewhat annoying. I can only imagine how it would be to try to play touchscreen intensive games, which demand fast and precise touches.
On my Nexus 4 I've also noticed that Chrome seems to slow the whole device, and for this reason I've also been using Dolphin for a while now (but I've yet not deleted Chrome, I just don't use it). Maybe I should dump the whole app from my phone. Also using Clean Master to clean up the memory from apps/processes helps for a while, but only for a while.
Google (or Asus) could verify if there's a sw patch on the way. I'm not a gamer, I mostly use the tablet for surfing and reading, but also these task are not a pleasure with the touchscreen issue. If this problem still persist after a month or so, I really think about returning the device (I bought it just a week ago).
Chrome is super slow.
I don't know why but the stock Android Browser is super fast and awesome. I've been using Next Browser since it is based on Stock Android Browser but the past 2 recent updates have really screwed it up where it is beyond usable. Once it gets resolved, Next is really awesome. It is like Stock on Steroids.
However, regarding touchscreen issues, DON'T GO LOOKING FOR PROBLEMS. If you aren't having issues, then just relax and enjoy your tablet. If your tablet was plagued with a quirky touchscreen driver, then you would notice it. If you can't notice any issues, then you don't have any issues.
Sure there are tests you can run but why bother? It is a software problem and will be fixed eventually. This is not the first Nexus with quirky touchscreen drivers. In fact almost all of my Nexus devices had quirky touchscreen issues out of the box. All were corrected within a few updates. Even the Nexus One had a physical hardware problem with crossing axis that was alleviated using some Google Magic.
May,
I have the exact same issue--but my missed touches are once every 5 minutes--quite annoying when typing an email or typing a password. I haven't unlocked the tablet yet to apply sfhub's fixes--will let you know how it goes.

Stock android is fast but how do you get it with stock rom? chrome replaces it in 4.3 isnt it? OR are you on a custom?
I think the reality is that many are having problems but do not know about it. They may just dismiss it as not being accurate with their own touches. Also for some users, it could likely be their first touch devices and have no prior experiences to compare with. When i've gotten this device, it was working well and all, but it just feels like typing aint that smooth and slowly over time, the problems starts to be more frequent.
There was an incident i had when after a few days of usage, i tried using it with it lying on the bed and it was going crazy - which never happened before. I picked it up (attempt to earth it) and lay it back down again but the results are the same. So i did a reboot with the system on the bed, and all the problems went away. So i'm not sure it has to do with the earthing factor which many are citing.
I think it is a combination of GPU/CPU/memory and touch related event handling factors that causes the problems to occur more frequently after extensive usage. There should be no reason for hardware to perform perfectly after a reboot only to fail over time.
Oh well, only time will tell when these problems would eventually be addressed.

I guess you mean the stock android browser. It may not be available as an app but it's still there as a WebView component available to developers. I guess Dolphin and many other 3rd party browsers are based on the WebView component or on the source code of it.
The problem with the so called stock browser and WebView is that is uses some legacy HTML and JS engine that has not been updated since 2010 or so. That is another crappy developer "feature" from Google that for 3rd party developers there's no "web browser" component that is based on some up to date rendering engine like Chrome's.
In the Themes and Apps thread, there is a method to allow you to install the stock Browser on a stock rom without being rooted.
Also using Sfhub ts10 gave me a 90% fix but it would still spaz out occasionally and would miss touches or click weird stuff. ts20 really fixed me up right. I can play games now and type with no errors.
ts10 is a really good fix, but ts20 really hit it home.
