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.

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

I have problem with the screen, whenever my finger sweats, the screen goes haywire. Any solution on this.

Capacitive touch screens detect anything that is conductive so it will register water/sweat/kool-aid. You just have to keep your fingers dry.

But I have been using phones like, galaxy s, s2, milestone, milestone 2, and some other phones. I have this kind of problem when using x10 and atrix only.
Sent from my MB860 using Tapatalk
I think it's more of a software thing, Motorola uses some sort of "liquid detection" (or something like that) on their phones which pretty much causes issues. Add that with the "multi-touch" bug the Atrix has then it just becomes a big mess. The Atrix will register moisture on the screen as a "touch" and then if it stays like that for 10 or 12 seconds then the screen goes bonkers.

Well my situation isn't related to wet fingers or moisture.
I don't think it is a matter of software bug either as its always the exact same area.
My last test was to use the Touch Test app and when I run my finger across the screen and it detects touch all the way across except a vertical strip from top to bottom. For instancr I can't use letters w, e, s, z when in portrait mode.

Does anyone know of any way to get better digitizer accuracy on this tablet? If I draw diagonal lines with any kind of stylus, the lines are always wavy and it's extremely frustrating to attempt to draw anything. I rooted my tablet in order to use the screen calibration tool in the market only to discover that it doesn't work on the tab 2... I guess I'll have to stick with drawing on my much smaller galaxy nexus for now.
Sent from my GT-P3113 using Tapatalk 2
The screen is accurate enough. There's no need to calibrate your digitizer, because the problem is - STYLUS.
Try to draw something with just a tip of your finger, it would be more accurate than a draw with a cheap stylus.

I have to disagree here. I've tried both dagi and cheap stylii, both have the issue on this tablet. If I go to my galaxy nexus with the same stylii, guess what? They draw straight lines.

The original galaxy tab 7" had the same issues, and the screen calibration app in the market allows adjustments to it to make it better. I have done a lot of reading on this and the difference these adjustments make is drastic. I wanted to see if anyone knew of anything similar for the tab 2, but instead I am met with people who are eager to reply without even doing the minimal amount of research or even have any clue what they are talking about.

It looks like the tab 10.1" also has this problem:

The touchscreen calibration information seems to be stored in melfas.bin firmware file since the tab 2 uses the melfas touchscreen driver. There's nothing to be found in the driver source or in sysfs. I've looked.
But you're right, I probably don't know what I'm talking about.

Was referring to the guy who told me I was using a cheap stylus when I never stated what I was using, and used both cheap and high quality stylii. It's frustrating to look for answers first, then ask questions, then have someone answer with false assumptions.

Dralanmage, did you ever find a solution to the screen calibration issue?
I notice that the majority of the screen is accurate. However, the edges are out by almost 0.5 cm. I verified this by tapping settings, developer options, show touches. I'm using the Samsung Galaxy Tab 2 7".

Nope. The screen is fairly accurate with a finger, but always draws wavy lines with any kind of stylus. Even with a finger, the lines are wavy. However, the amplitude of the waves is much lower so it's not as noticeable.

Same with the vzw tab. Scrolling in landscape is annoying as hell unless you add more finger surface area..

No progress has been made, yet. Some think it will be fixed in a software update. When I notified Google support of the issue, they thought it was a hardware problem, but if several people have the issue, maybe it's software.
I'm hoping it is fixed in a software update. That is literally the only issue I have with the tablet.

Yeah I hope so too, but I already have a replacement on the way. I have some other issues with mine though that I felt warranted getting a replacement.
Does the tearing happen to you all the time or just in certain apps? It only happens on mine when I'm playing music. It will show up for a split second as a quick horizontal line then disappear. The line appears in different areas of the screen each time. I notice it the most when it happens in Chrome, but I've seen it on the homescreen and in other apps as well.
Mine happens frequently throughout the ui. Xda app, chrome, everywhere really. If it is a software issue though there really is no point in exchanging. It seems to happen more frequently in an app with a light background.

So apparently it was a bad kernel that I was using that caused the problems. Flashed a completely stock build and the problems are gone. To the people that chimed in and said they had the issue, are you on a stock ROM or did you change that and the kernel?

I've noticed this, but it's only happened twice (so far), Once was whilst using chrome, the other time just sat on the homescreen. I'm currently using stock.
(Not too worried, just as long as it's not a line of pixels about to give up the ghost as some other people have had).

Happens to me on stock rom. My N7 is not rooted or unlocked.
Pretty sure this only happens when you force GPU acceleration. I had the same issue, turned it off, and never saw it again.
Of course I love GPU acceleration too much to leave it off, but a jagged line every once in a while is not a deal-breaker for me.

Glad it worked for you, but I don't have that option on nor any other's enabled in the development menu. Regardless, the issue persists.
Is there anyone else having this issue?
I received a replacement today, but I couldn't escape defects on that on that one either. I'm trying to figure out if I should hang in there for a fix on the screen tearing/horizontal line issue, or if I should just send both back and call it a day.

People here think the screen flickering issue could be resolved in software, but I'm not sure about the issue we are having.
I might go through the unlocking process just to see if the horizontal line stuff happens on other roms/kernels.
I really hope it can be addressed in a software update. I just struck out on my 3rd nexus. All of them have screen defects. All have had other issues like creaking and slight screen lift, but those are a lot less of a problem to me. The original one is ok except for the horizontal line issue. My two replacements each have dead pixels and dust in central areas of the screen.
This is ending up to be a very tiring and disappointing pursuit.
If it's a software problem it's likely to be in the tegra3 proprietary driver blobs. If this is indeed the case, changing rom and/or kernel will make little difference (because they share the same blobs).
It might be possible to work around the issue outside of the blobs but its likely only nvidia can fix the root cause.

Hopefully someone at Google watches some of these threads. I have 2 nexus 7s with this issue. Thanks for trying to save me the time of trying a different ROM/kernel, but I might still try a CM10 build for kicks.
My first tablet had one dead pixel and it had this issue too. My second one is perfect except for this problem. It probably does have to do with the tegra 3. I hope its a software issue because this one is perfect except for that one problem. I'm not rooted nor unlocked and no force GPU rendering either. It only occurs on some apps with mine. Tapatalk, facebook and barely ever on chrome. I haven't seen it on any games or video nor on the home screen. There should be a place to report this to Google... I doubt they are searching through xda looking for every little problem. I've had this issue for a while and have been searching specifically for bit and just found it today. Also I never see it in horizontal mode.

I have this issue too and I think it's likely to be a driver issue as it appearance seems random and sporadic in frequency, but it's always really hard to tell about these things.
In any I'm guessing some people just don't notice this issue and thus haven't really talked about it. But it sure is discomforting seeing it.
I seem to suffer from this too.. Everything is stock on mine, no mods, no flashes no unlocks.. It appears to be worse when its been on for a long time.. Wondering if its heat related?
Hi, wondering if others had similar problems or fixes.
After a while of use, the touchscreen becomes unprecise and quite unresponsive. For example, it becomes difficult to input strokes or use the keyboard. This problem disappears when I immediately sleep and reawake the device.
Any ideas?
Thanks!!!

Has anyone noticed that the screen on this phone is way too sensitive? Mine goes as far as to register a touch when I hold my finger a few millimeters away. This results in accidental double presses and is very frustrating especially when typing. I even made sure the high sensitivity setting was off.
When in Camera mode, it even snaps photos by itself without my finger anywhere near the shutter button.
Any tips?

As stated in OP I had made sure that the hi sensitivity option is off as well as any other convenience features.
As for the camera, I have been in windy conditions when this was occurring, so maybe it was thinking I was giving voice commands. But I had all of that turned off as well, so I'm not sure what the deal is.
I will probably revert to factory settings again before returning the phone to make sure it's not a software issue.
I think that Samsung went a little overboard with the touchscreen on this phone. I do not like the fact that everything can be used to touch the screen. What I actually liked about my iPhone 4s was that it was picky about only recognizing fingertip touches.
Great phone overall but this issue sadly ruins it for me. I do not want to go back to iOS so I think HTC One is the only other strong competitor.
