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..

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.

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.
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.

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...

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 2 Nexus 4 (one for sister and one for girlfriend), which were both purchased last week and arrived this week. Both their serial number starts with 301K.
Here is the weird part: for one of the phone, it is very easy to see under the glass. When there is adequate lighting and the display is off, it is very easy to the see the circuit-like component just under the glass. This is not true for the other phone. The display also has a more of a yellow tint than the normal one. Otherwise, the display looks and works fine.
Anyone else also experiencing this, or know what's the cause of this issue?
Thanks!
This is how the pattern looks like under the screen:

It's because the touch screen sensor (I don't know the correct term) is closer. Basically it isn't an issue, it's a design. Nothing to worry about.

I guess that's something we'll get with the next update (hopefully). That is assuming it's got to do with camera rather than any other sensors.
I don't think airview will work well with your finger as your finger or a capasitive stylus requires too much real estate to register. Where the s-pen can be very selective due to it's size.
This has been made on some devices, but I'm not sure the Note II's screen is compatible.
As far as I know the Spen has an onboard transducer that communicates with the phone, so unless you embed a transducer in your finger it's not gonna happen anytime soon.....lol.
I think he means the same feature on s4.
It should be possible for the note 2 as well unless the screen technology on s4 is something completely new.

My apologies - I did'nt know the S4 could do that, but I'm pretty sure the note 2 talks to a transducer in the Spen - read it somewhere.

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?

There is a mode you need to turn off which makes it more sensitive. For winter and gloves.

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.
