Unresponsive touchscreen on some points.

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?

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

From what I've seen, others with similar problems have returned their Nexus 7 to the store they got it from and exchanged it for a working N7. I would recommend you do the same. If you got yours from the Play store, start an RMA. If you got it from a B&M store, exchange it.
Since you've only had your N7 a week, you shouldn't have any problems exchanging it.

It seems like it's an issue with the touchscreen itself. I have no idea how to verify or solve this issue, though. That's why I would personally exchange the N7 as defective. I would think that since your problem is clearly demonstrable, it would be easy to exchange or RMA.
But there may be a solution around that someone else has heard of. If anyone with greater knowledge of touchscreen issues wants to weigh in on this, please do.

I just started seeing this issue. At first it was only happening within apps. I thought it was issue with maybe stretching the app to a larger screen. But I started seeing it on the home screen.

There was a fix posted here somewhere for a package called surfaceflinger-fix.zip you flash in recovery. Made a huge difference on the touchscreen non responsive issue.

and when you turn off display and turn on again problem will fix

I have also experienced this. I I didn't try turning screen off then on but I rebooted then it was fine again.
I'm more inclined to think that this is a driver bug than a hardware fault

Pinch to zoom quick sand?

Thinking about the N4 as a secondary phone but I played with one in the T-Mobile store and noticed that pinch to zoom seemed to be pretty unresponsive and disappointing and that's putting it lightly. When pinching to zoom it felt as if I was moving my fingers through quick sand. It was as if my fingers had to literally transverse half of the entire screen before the phone started to react. Can anyone else confirm this? Like I said, this will be my secondary phone and my primary will be an iPhone 5 so I will going back and forth between the 2 phones often which will make the poor responsiveness even more noticeable and bloody annoying since the iPhone is very responsive and accurate in this department. So now I'm rethinking my purchase of this phone. Again can anyone confirm this??? Thanks

mine doesn't do this. it is very responsive.. are you talking about having to go out farther when zooming in? i think they designed the zoom in to occur after your fingers have spread over a certain distance so you don't accidentally zoom in when you don't mean to.

Its like people are just finding reason not to buy this phone cause it has real issues or they just like to complain....personal I think your all crazy . My coworker got his nexus 4 last week and its ****ing awesome the camera in HDR mode is amazing the data speeds are top notch and the screen is responsive. I don't know it everyone and there mama was playing with the display phone at T-Mobile ,but here a story I was playing with a Gs3 at T-Mobile and found pictures of a girls ***** on it .

There was another thread on this yesterday - this is actually Google almost certainly designing around someone else's patent on touchscreen usage. They probably figured that what was going on in older versions was too close to Apple's or someone else's precise method for interpreting multitouch input, so they designed something effective but different enough to avoid litigation. There's a reason why neither Apple nor Microsoft have sued Google directly over Android - Google designs around patents pretty well.

I wrote about this yday... Seriously. . try Firefox
Also , qickpix for gallery doesnt have the issue either

but why should you zoom in accidentally? you use two fingers to zoom..

I hear ya, but even still it'd pretty annoying and making me think before I buy. Honestly I'm a stock app kinda guy. I like the stock apps, I actually want to use Chrome but I can't, I want to use the stock gallery since it would be more integrated but I can't without this bug/feature this will also make using Google maps bloody annoying more than anything as when using maps there is a lot of zooming in and out. I'm wondering if other ROMs have this issue with the N4 or not.... Hmmm... That would be an indicator if there was more of a real issue/hardware level issue or not. Wondering if Cyanogen, Paranoid, or AOKP would have the same issue...

this is such a moot issue based completely on software filtering/calibration of your touches. Capacitors are hyper sensitive to touches, so much so that you have to tone it down and filter out all the noise... You can easily go into the software and figure out where the pinch-zoom controls are and fix them...
I am running codefireX's build and my pinch to zoom works perfectly in gallery, chrome, maps, camera. Registers my touch input no mater what I try.
If this is a deal breaker for you, I would be more worried about thermal throttling issues tbh... Those are actually hardware related.

So you're saying right out of the box you can go into settings and configure pin h to zoom to react immediately rather than after transversing half the screen before it starts reacting?

Well, this is xda developers where we hack software and improve it for our own uses. Its part of the fun. You would have to get into the kernel for that

4.3 performance

Installed 4.3 and did a full wipe. Beenbhaving a strange delay in Chrome. Sometimes it will take 3-5 second when I click link, bookmark, or new URL. Tried turning off the wifi optimization and thought it helped at first but actually did not. Driving me nuts and about to completely really err to stock and start over. Didn't have this issue on 4.2 but I was ruining AOKP for a long time... Anyone else notice this?

I don't have 4.3 yet, but I noticed a strange issue with Chrome about a week ago when it installed an update. When I open Chrome, it starts out black &white, twitches for a second or two, then goes to normal color. This only happens opening it from a complete tablet shutdown or closing out the browser completely to a black screen then returning. Other than that, it's no different than before

No issues on mine as i use chrome as my only browser. Only thing bothering me is when i click on something small, chrome zooms in first then i will have to re click again. This was happening to be before 4.2.2 as well.

That's actually not a glitch. Its a feature. Chrome does that when it isn't sure what link you're tapping, so instead of making a mistake it zooms in so that you can pick the link more accurately.
Just watch where you tap more closely, and you'll be fine. You'd be worse off without it, IMO.

Yeah i figured it was a feature but still annoying. I dont remember this happening with safari on my ipad.

The black and white tab means the tab had been forced out of memory and needs to reload. Once the page reloads it displays in color again.

Performance has taken a nose dive for me. This thing is really sluggish. Just bought a new Nexus 7 for my wife and that thing runs circles around my 10. Custom kernels just make things worse.

I have you determined if it's actually a performance issue or wifi issue? In my case it's clearly just wifi.
FYI... Seeing how this thread went completely off topic I continued this discussion in another thread that was started...

S8 fingerprint lag?

Please have a look at this video as it is driving me insane. Is this lag normal? it doesnt do it all the time and sorry the video isn't the best. The apps seem to reload or "jump". I thought it was just on homescreen but it seems to do it in apps too.
https://youtu.be/RVu2RzM_iW4

Even my S8 lags while unlocking. Sometimes it wont detect my fingerprint. I have registered only my index fingers (each finger has been registered twice, to increase accuracy).
Would be nice if someone suggests a fix to make it better.

Mine does the same thing. It was not a fast fingerprint reader to begin with.

Mine does exactly the opposite. Its always responsive , faster than iris regognition and it unlocks without having to tap screen or by pressing the power button. Actually one thing i actaully love and its practical a.f si the fingerprint sensor. Even the fact that is positioned on the back.

Here too. It acts like my phone doesn't even know my finger is on the scanner.
It usually works, but sometimes I have to unlock it with the password because of this issue.
Very annoying.
