Keys randomly dont work??

Hi, has anyone had the problem where certain keys on your keyboard randomly don't work but the keys around it do? I have to turn the screen off a few times to get it to work again. It happens very often, is there any fix? This is the first android phone that I've had a issue with the keyboard with. (nexus one and g2 were fine)
Using Gingeritis (beta IV) (Happens on the other roms too) and smart keyboard pro (tried the gingerbread keyboard same problem)
Thanks

I get this problem too.
I've noticed it on all of the ROMs I've used.
Doesn't matter if it's stock keyboard, SwiftKey, or SlideIT, I still get that problem.

Double check that you are not accidentally resting your finger on one of the touch buttons on the phone. i had this problem when i first got my Thunderbolt and realized it was how i was holding the phone.

I've noticed this too, and like the person above me said, its usually because my hand barely rests on the search button. I guess its far enough off that it doesn't register it as touching the button, but still a part of the touch screen? Either way, moving my hand fixes it.

My buddy had this problem where the screen was unresponsive and he called VZW about it and they acknowledged that it is a known problem. Sorry dont know a fix but apparently VZW knows about it.

for me, the problem hasnt been a key on the keyboard not working, but lits of times when i am in the middle of typing, the keyboard will disappear & when i bring it up again, the cursor will be in a completely different place.
additionally, sometimes when i press on a link nothing will happen. ill have to press 2-3 times before it registers. and as with the unresponsive key issue, this is also with any rom.
the cursor issue though seems to be worse on aosp roms.

I get this issue as well. It is VERY frustrating. I'm using swiftkey

I had trouble getting letter "k" to work today in smart keyboard pro . It took 4 tries.

I'm trying TouchPal, so far so good.

I've had this problem happen with EVERY ROM I've flashed and with multiple keyboards (HTC KB, GB KB, Swiftkey, etc.)

So will they replace phones? It's hella annoying.

They did offer to swap it for him. He is a unique case though, he is on his fourth or fifth tb. he has called vzw so many times and complained about his phone, they are going to give him a bionic when it comes out. so he declined the swap, but it was offered.

Nexus S touchscreen calibration?

Hey guys, is there a way to calibrate the nexus s touchscreen? Sometimes it is unresponsive...

Anybody?

unresponsive? Maybe you just need to make a good wipe and fresh instal of your rom/kernel..
no?

I don't think so because it happened since gingerbread 2.3.6, and now i have brainmaster's stock 4.0.3 with eugene's kernel and still happens sometimes... and i did a full wipe before flashing ICS.

i used the nook screen calibrator from the market...it worked fine for me

I'll give it a shot and let you know, thanks. BTW, on the market i've found Nook Screen Recalibrate, it is the same as you used, right?
Edit: I've tried the app and it managed to improve the touchscreen response, but didn't solve my problem at all (phantom touches). But they're almost gone. Is there any other app like that?

Same thing with mine. The phantom touches are only vertical but the device has become unusable.
I'm installing Cyanogenmod 10 now. Let's see if that helps.

It didn't help. touch seems to work but if I hold the touch the touch sensor goes crazy and starts touching several random points in the screen, all in the same vertical as the place I touch.
Does anyone have any suggestions?

Could be but since the problem started after I ran the Nook Screen Recalibrate my first suspicion was the program.
I'm trying several different solutions from other threads and none seems to work:
- TouchRecalibrate.apk
- calibration.ini
- ts_calib-signed.zip

If you wipe everything and flash a rom, there's no way it's a software issue.

Well, it's working now. I don't know exactly what soved the problem but in my despair I re-executed all procedures and something must have gone right. Wish I could tell what fixed it for others but I really don't know.
Thanks for the help polobunny

Same problem
Hey,
I got the same problem,
so I did some research, I found out that there lots of people got the same problem.
A wipe, or install an other kernel or rom will work, but it will for some reason return.
For some models it's enough to install a kernel with some other touchscreen preference. One problem, it will only work on android 2.3 there are not jet other newer kernels published
But 99% its not a screen problem, so u can buy a new screen and replace it with no success. But most of the people say it's a hardware problem. So modify the touchscreen driver.
sorry, bad english​

Hmmm... I am going through a similar problem... I've noticed that when this unresponsiveness occurs and I keep my phone for charging the touch becomes normal again. But as soon as I disconnect the problem comes back.
I had this issue before too. When I was on TheFrankestains miui v10.5... And now I am on RemICS v2.
I'll like to mention here that on v1 of RemICS I didn't face this issue. In v2 the developer did mention a change in the kernel.
Also another er thing with the unresponsiveness the bln is acting weird too. Now I don't know what to conclude from all this.
And ya when it had occurred before I did take it to the customer service. And all they did was remove my screen guard and reflash the stock. :what:
The problem disappeared that time but it has resurfaced again. :sly:

Even I'm facing this issue and thats the exact reason i'm not going to service center. I doubt its a H/W issue cause the screen does work! If it had been a H/W problem then the shouldnt have been any touch response!
Its might be similar to backlight issue but too bad we're facing it on stock aswell.
I had posted a logcat in the dev ICS thread but no response from anyone.
If there are more people facing this issue then please come forward.
I got only one phone. . And i cant use it.

I'm on ICS Alpha V6 . I get this problem occasionally.
Problem occurs when i get a call and the touch becomes unresponsive. Not all the times but sometime. If i lock the screen and unlock it becomes proper. Sometimes it takes 2-3 locks and unlocks. Weird. Never had this problem in stock before .

Everytime this problem starts after a call. Happens on stock as well as custom Roms. Can't figure out if it's software or hardware problem. But the touch becomes normal when the phone's kept on charging.
Anyways going back to the customer service tomorrow. Will tell them to change the touch panel.

Probably Hardware, i am using RemICS v2 and NOT experiencing this issue on both my device and my sister's device (tried the call thing too)
I advise you guys to go to the service center (without a screen protector) and with the stock rom (so they don't have to flash anything) so they see it live, and hence there's no point of flashing stock again (over stock lulz) they'll probably change the screen for you.

i have the same problem now.. i dunno if i will ever get this phone fixed. my warranty's expired for a month.

Everyone needs Help here dude...!!!
Same problem for everyone...

is it more likely to be a hardware issue??

It is a Hardware issue.
I gave my phone to the Service Centre yesterday. I called them today to check on the status. They said it's a hardware issue so they'll give it tomorrow. Let's hope for the best...
BTW I will get an extended warranty on the replaced part, won't I?

And the problem is back. Not entirely though.
After deep sleep if I unlock the phone, the touchscreen doesn't work. I have to lock and unlock to get it working.
After unlocking, once the display goes off, the menu and back keys stop working. Have to lock unlock again.
Had flashed cm9 stock kernel yesterday morning since gps isn't working for me in UCv15. Didn't face any problem yesterday after flashing stock kernel.

by back cover you mean protective case? if so, yes i do!
and the touch panel means the digitizer right?

Big Touchscreen Problem

Hey Guys, i just recieved my TF300T , but i have a problem with it...
I cant use the Touchscreen it just does what it wants. If i have opened the Onscreen Keyboard it sometimes just "presses" random letters even if my Hand isn't nearly the screen. Is there anyway to fix it ? I already reseted it but it didnt work.
I hope you can understand what i mean...Im from Germany so my English isnt that good

I have bought the same device last month and i know what you mean.
Sometimes the touchsreen keyboard woks without problems and sometimes go got the letter more than onetimes and when you delete it you delete more letters. Really strange problem.
I realize that the keyboard reacts some milimeters over the touchscreen it reacts very sensitive i do not know if this is a software or a hardware bug.
If you turn the display more times of and one it works again normal.
Have you found a solution for the problem.
I have on my device Asus TF300T with 16GB, CM 10 installed from the begining because i would like to have root an my device.
any ideas?

Is the tablet brand new and behaving this way? If so, try to get the tablet to fully update to the latest version. Once updated, do another factory reset for good measure. If you are still having these touch issues, I would contact the reseller as you might have a defective digitizer.

Ive had the tf300t for about 6 months now and mine has been doing it since day one.I even brought one back to store and got a new one and it still did it.I just turn screen off and back on and it works fine.I am rooted and have custom rom and it has done it with every rom i had on here.Ive tried reset,factory reset,and wipe everything and start over and it still does it.It doesnt happen that much so im kinda use to it now.My advice is to just turn screen off and back on.

Turning "Show touches" on in the developer options might help
