something weird

go to the home screen and have your finger sliding to the next home screen but do it at an angle and do it toward the bottom of the screen and move your finger down to the four buttons and you can flip homescreens with your finger on the buttons . still detects your finger moving when its not even touching the the screen really ,

its designed like that. Technically the touch sensitive part of the screen goes all the way down past the buttons.

Stuck/dead pixel!

My brand new pad has a pixel that won't show green...running one of the apps that says it fixes that... If it doesn't work, i'm going to see if I can get a replacement.
Just a warning to everyone. Be on the lookout.

I've got a dead pixel as well. Near the top left. Doesn't really bother me that much, so I don't really care. Surely one teeny little pixel doesn't warrant you returning it ...?

I used to think that. But if its been like, 3 Weeks and there's already one dead pixel... What does that say for the possibilities?
Just called Asus - he tried to get me to do a wipe.
Are you kidding me? wipe all my data? Asus - get rid of the spiel, its junk. Get ppl who know whats up on the phones ugh

My first pad had a dead pixel. I found it the second day and returned it as soon as I could. It was kind of in the middle of the screen, and I could see it every time I viewed a white web page. Needless to say, it bothered the heck out of me and had to be returned.

i went through 4 tabs until i got one that was fine display wise. first one had a cluster of discolored pixels, like someone pressed their thumb hard on the screen and damaged the area. the other two each had a couple grains of what looked like sand under the glass. All of these were around the same area on the tab, mid-lower left area of the screen.

Mines mid high right...
I'm worried about an attempted unlocking... I tried to unlock my tab before they fixed the c4okt issues, and im wondering if it might've sent them a file about that... Also wondering if unlocking will void it for a screen issue.

Dead and stuck pixels are far from unique to Asus. There is a difference by the way, a stuck pixel is one that is, well stuck displaying one color, these can sometimes be fixed by programs like you are running and/or gently massaging the area with a pencil eraser or something similar, dead pixels don't display any color and are rarely able to be fixed.

My dead pixel I guess just happens to be in a place where I rarely notice it. I tried one of those dead pixel detect and fix apps but it didn't fix anything.

There is one other thing you can try, VERY gently massage the dead pixel with a something like a pencil eraser, that will sometimes get it working.

That's fine and all... but there's a much thicker layer of glass over a capacitive screen than there is over a resistive touch screen... or just a LCD monitor.
Unless I'm missing something here, this advice does not apply anymore.

The screen will still flex. I am not sure whether it would work or not on these devices, I just put that out there hoping it might help.

Don't feel too bad. I just made the mistake of looking at an all black screen on my Acer a510.
NINE stuck pixels!
One little cluster made a shape exactly like the big dipper. Very artistic, with pretty multicolored stuck-pixel stars.
Needless to say I wasn't thrilled. So much for quality control. Sounds like Asus at least isn't this bad.

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

Screen calibration for galaxy tab 2 7"

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.

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..

Capacitive touchscreen works on sensing the change in the capacitance when touched. Water creates trouble as its capacitance is close to that of human body so if water touches the screen, it behaves as if being touched at multiple points.
Also it stops reacting to human touch as it cannot distinguish it from water.
Google it for more detailed description of touchscreens.
