After using the new SGTab 2 7" I have experiencing the touchscreen is unresponsive in some occasions.
For example closing the tabs in the brrowser on the X mark is very hard, both in the stock browser and Chrome.
When I try to clear my mssage in the bottom right corner, it also doesn't recognize my touch on various occasions.
It seems to me that along the edges of the screen, the touches are harder to recognize. Have any of you recognized this problem aswell?
After reading a review on Techradar.com, this passage stood out for me:
''Disappointingly, we found the touchscreen experience to be a little sub-par. The sensitivity of the display was lower than we expected, and we found it hard to register presses on small parts of the browser, such as links, and the close tab button.''

I encountered the same fault/defect on my Tab2 10.1
especially on small objects,
but it seems not to be constant.
meaning it generally works, but sometime i have to press multiple times to activate the selected button or object.
I found that fingerprints really lower the sensitivity of the screen. If you wipe off the screen after prolonged use, the touch experience will be much better. I verified this using a touch recognition program.

Yeah I wipe and I wipe haha..on all my devices. But it seems worse on this device, compared to all others even though I clean very often.
Cheers for your suggestion though

thats true
some times happens to me too in youte app, i notice it only there still.
Same thing here, it gets incredibly frustrating for me. It's very noticeable trying to close a tab.

Is it a hardware or software issue?
Software...lately it doesn't happen anymore..on and off

Got mine today. And ive been fine, then again i have a crappy screen protector lol.
After rooting and flash a custom rom on p5100, everything is OK. Become responsive. So I believe Samsung touchwiz on ics might be the cause of the problem.
Yeah me too not satisfied with the samsung touch wiz...but I don't think I am having problem with touch screen...though it is not as smooth as with iPhone 4...

Do you have a screen protector on? Mine was crappy with it on, so i removed it.

Had this problem when I was on Stock. Not dead touch points but it was more like an inability to sense my touch due to lag due to touchwiz. Changing to nova launcher helped... And then.... Tried CM9 rom and all is well. Not sure if you wanna take that route but for me... It worked. I am a happy camper!

Is there a way to calibrate the screen on the T2 10.1?
After 10 minutes of reckless racing 2, the screen gets unresponsive, i think it might be something to do with the battery or cpu getting hot, I am using the stock modified rom from metallice
Occasionally, a horizontal or vertical line flashes on the screen very quickly and then disappears. Does anybody else have that? Is it anything to worry about, or does it not matter? Is it likely that a software update will fix this?
Thanks for any replies!
First, are you running a custom kernel or stock?

I have not rooted my device. I have flash installed and Iplayer, but apart from that all my apps come directly from the Google appstore...

Damn it! I was seeing this on occasion and hoped that if I just thought I was crazy I wouldn't have to acknowledge it. Now I see it's not my imagination. It happens only rarely and it's really just a blip, but it is indeed weird. I just unlocked/rooted last night though so I'll have to see if it still happens now...
Always happens to me, really only noticeable on mostly white screens like in xda app.

First device had this issue, took it back (for many reasons), and have not noticed that little "subliminal" black line anymore.
Happens to me too, so far only seen it in the xda app, and in my browser while waiting for a Page to load that is taking a while.... I'm currently waiting for an exchange because I have a slight screen lift issue, but I doubt it will fix this black line problem, it is probably standard on these things. I guess I can live with it

I get it like once every 10 hours or so and only when using xda app or chrome for some reason.

Yep, I see it with tapatalk. Haven't noticed it with anything else just yet.

I also get it a lot when playing an online chess game. It seems related to the apps used. Don't know what to make of it...

Could it be a memory leak or a GPU rendering issue as some have suggested? Many of us get this on the stock ROM with no developer menu changes.
I notice it too. I thought I was seeing things. It is not serious enough to give a crap though. I just hope it does not evolve into a worse issue.
It probably has to do with spotty Tegra drivers. I noticed it slightly on Chrome, but never on anything else.

I've seen this quite a bit also. Seems most prevalent for me when I'm using the GPS Status & Toolbox app from EclipSim, except in that app the lines are white.
I think you guys are referring to screen tearing. I have seen it a few times to I think in chrome. Pretty sure its not a hardware problem.

I haven't noticed it at all on the nexus. I have had this issue on my tf201 though.

Hmmm... seems this thread should be combined with the other regarding the same issue: http://forum.xda-developers.com/showthread.php?t=1791281
Yeah I get this too I'm hoping its a software issue it doesn't happen often but I seem to only notice it on tapatalk or the Facebook app. I haven't seen it on games or videos.

I see this on occasion with the xda app. I haven't seen it all using anything else. I'm no overly concerned.

I get that in Tapatalk once in a while. I would guess its a coding thing and not a device defect.

I have three users configured and at times the tablet seems to lock up. But I can still pull down the notification drawer and setting drawer. I can touch the back, home, or multitask softkeys, or slide up for Google now.
But no matter where I navigate to, the N7 does not register touches in the "screen" area.
I have found that pulling down the setting drawer and tapping the user to "logout" and then logging back in immediately fixes the issue. Also toggling sleep/wake button and logging back in also fixes it.
Is this a known issue? Is this multiuser, software or hardware specific? Any solutions?
(I read back through a couple weeks of posts but didn't see this issue)
--- UPDATE------
Just happened again. But I left it alone for a minute, picked it back up and it was working fine. Perhaps this is app lag. The notification and navi bar work because they're systems but the screen stops taking input while it lags....(just a thought, I don't know how that stuff might work)
BTW I have a 32 GB N7, it is not rooted, and is fully up to date running 4.2.1

Im having the same issue with mine..just got it afew days ago and it just started about an hour ago. I think its a screen issue cause now it keeps coming up with the menu to change wallpapers without me touching it. And its been locking up alot. Might have to RMA it.

RMA it? Is yours rooted? Do you have multiple users?

Do you have an otg cable? Try connecting a mouse to it when it does this and see if it recognizes mouse actions.

This is not a question it is an issue with the device. This is appropriate for general.

Damn. Well maybe get a log cat next time it happens. Maybe there will be something there to show why it stopped working.
Sent from my Nexus 7 using XDA Premium HD app
I'll have to learn how to get a logcat. But I was able to recreate the issue and get a video. I could only get it to affect settings and the play store but I've had this in the launcher before too. I don't think you can hear but tapping the screen was causing the touch sound.

No one has had this issue? I've only experienced it in Settings and PlayStore on me first and second user, nothing on my third user. Also noticed a litte lag on the homescreen too.
In the video you may be able to hear the touch feedback sound. The screen is recognizing taps but not doing anything. Sleep/Wake fixes the issue until you leave the app...
Guess I'll need to exchange my N7 and hope to get one without this issue.
Why did this get moved to Q&A??
Are Issues not discussed in General?
[SOLVED]
I was using APP LOCK on User #3 and that caused what seems like an overlay that prevented touch on users 1&2.
I sent this issue to the apps support. And will try to find a free app locker that is milti-user friendly.

Randomly it seems, when I tap on the touchscreen on my new N7 2013, nothing happens, and I have to repeat the process several times before my touches are registered.
Does anyone else have this problem?

See my thread titled " Another touch issue, with reproducible steps".
Go into developer options and enable "Show touches" and "Pointer location"
If you see your touches registering but the app isn't responding, it is probably a problem with the app. If you see random stuff on the screen, probably a problem with the digitizer or digitizer in combination with the driver/software in this release.
Ive experienced this a few times and it seems to be a software /hardware interface issue with particular custom rom builds ive installed. I know the touchscreen hardware itself was fine when I forced reboot into recovery and the touchscreen worked as normal in custom recovery.

Is everyone experiencing this or is it only certain units. Mine does it even when holding and firmly pressing. Gonna take it back and try another if its not all.

I wouldn't. If you had a Verizon Galaxy Nexus when it came out, you'll remember that it had the same issue with certain points on the screen (lower right hand corner) when using multi-touch applications. The entire screen would either stop seeing input or start going erratic and creating faulty inputs that weren't happening. It isn't a hardware issue, proven by some users experiencing it and some not. The only time I've experienced it is in the Netflix application while trying to choose a show to watch. I re-boot the application and viola, no more issue. Some in this thread even are stating that they only see the problem sometimes after getting the 4.3 update.
In short, it's software and not hardware.
Same issue when not touching with both hands somehow (like if the tablet is flat on a table).

Haven't had a problem with mine. I just got it today, and it's worked like a charm. I bought mine from Gamestop if that helps any.
Hi Guys
I seem to be suffering from a issue where the touchscreen has a dead spot.
Now I had an earlier issue that caused all sorts of issues with screen responses - ultimately ending in no response unless I hit the power button to lock and then unlock.
That problem lasted about a week and then stopped - my thinking is that there was an app update that solved it.
Now however the issue has resurfaced (seemingly after other app updates) but it is a dead spot roughly where the first notification would be on the notification draw. Any ideas as how best to find out the cause of the issue, or a fix?
I've included screen shots showing the touch trace.
Cheers for any help

I can't help you but with some custom rom there can be a bug with it until I make some setting changes to the Nav Bar, but otherwise I don't know.
Forgot to say that this is stock 4.3

Many people are complaining about 4.3... It's causing many problems

What I don't get is why it went away after the first time.
I don't really want to factory reset if I can help it.
Is there a way to look at an update history for all your apps? Then I can pinpoint the offender.
Sent from my Nexus 4 using xda app-developers app
I've found a solution.
After factory reset and safe mode not helping I came across a comment in another thread.
You have to Disable HW Overlays and Force GPU Rendering. Now its not perfect and can have an occasional fit but does seem to solve the issue
