Need to know if anyone here with a Touch Pro device ever had the hardware keyboard just stop working. I cannot time when it will happen it varies. I can slide out the keyboard to respond to a message the backlight is on the all of a sudden after a little tyoing the light goes off and no key I press shows up. All of the screen keyboards work no issues. I have to do a soft reset to get it back. Today before it locked one of the keys I pressed was still in memory and I had rrrrrrrrrrrrrrrrrr all over the screen. I had to take the pen and cancel the message but the keyboard was not working anymore.
I called Verizon they had me change my backlight setting thinking it was that but of course it did not. Now they are saying a device replacement...guess I should have gotten the insurance.
Is there any advice someone can offer me on this problem?
I've had this happen to me one or two times, and the times that I've had the problem I've fixed it but soft resetting. I've just brushed it off as one of the quirks, and I haven't worried about it since it hasn't happened in a while. If it continues to occur I guess I would see what you're carrier can do for you
Mine did that a mutliple of times. Same exact scenario. Since I upgraded to energyrom, hasnt done it once. If I had to take a guess, some glitch in the preloaded rom?
I have been having issues with my Droid 2 Global with the touch screen. From time to time it will go crazy and start typing or opening up apps. Sometimes it will open the apps around the lower part of the screen and other times it is an up and down motion that continues untill I lock the screen. Locking the screen will fix it sometimes others I have to pull the battery. I have had this issue with several Roms. I ran 2 different RCs of Venus and now I am running CM9. If anyone else has heard of this or knows something I can try please share the info. Thanks.
Yes, I had a very similar issue. My phone would detect screen presses around the bottom, usually near the unlock slider. It would actually cause my phone to open up my email and delete things on its' own. My only temporary fix was to lock the screen, try to wipe it off, and then unlock it again.
It's a hardware issue with the glass/digitizer, not a software issue. I fixed it by buying a replacement screen on eBay, and haven't had any problems since. If you do replace it yourself, make sure to do it in a clean environment with no dust, and save the tape that covers the speaker, or else dirt and dust will get inside the phone and make the screen look dirty.
Hey guys,
Had my transformer for 2weeks now and loving it. However recently (first noticed it 2 days ago) the notification bar has randomly started opening itself. It doesnt happen on a regular schedule -sometimes it will happen 3 or4 times in a couple of minutes, sometimes only once or twice an hour but not less often than that.
It happens even when im not touching the tablet at the time so i dont think the screen accuracy/calibration would be causing it.
I have turned it off and off a number of times to no avail and Ive also tried a factory reset and even with no additional apps installed it still happens.
Finally ive tried it both with and without sd card in and it happens in both situations.
Oh, and the dock connector being attached or unattached doesnt stop it either.
Has anyone heard of this happening before and or have any ideas to solve this problem?
i get this too all the time. i'm not touching the screen and the notification pops up for no reason. sometimes apps open up randomly too, for example i get an email notification and the email app opens. very annoying when plugged into a projector whilst giving a presentation.
somebody must be able to help. I'm not rooted by the way and have no intention too.
Sounds like a hardware problem - the touchscreen registering fake touch events. Check for mechanical stress in the lower right corner.
Update
I probably should have added, like yours mine isn't rooted.
I also turned on the developer options for touch detection, and it's definitely detecting "phantom" touches in the bottom right corner so definitely hardware not software issue.
Unfortunately, yesterday I started having issues with the touch screen being unresponsive in the right third or so of the screen, so I've called Asus this morning and am RMAing the tablet anyway.
I'd suggest you do the same rob if it's still in warranty, in case its a prelude to larger issues like mine was.
interesting thanks both. i was weighing up an rma because my keyboard dock is getting very loose, letting the top of tablet move about an inch without hinge moving. i've turned on show screen taps and already seen one. thanks again.
I had issues with my Asus TF700t that quite often it did not react on touch gestures.
And on the home screen the "change backround" dialog opened sometimes without any touch on the device.
This happend very very often when it was in the dock, but also without the dock (less occurence).
Now i know that the reason are ghost touches. By the usage of touch test apps (e.g. "Simple Touchscreen Tester" oder "Yet Another MultiTouch Test") i realized the ghost touches.
This touches are recognized always on the same coordinates. The multitouch test app detects 4 fingers on the same y-axis.
When the tab is in the dock and i open it completely to the maximum the two bolts from the dock are pressing very strong to the background of the screen glass. This is causing the ghost touches.
I opened the tab and tried to find what could be wrong (especially on the area where the touches are detected).
Anyhow i could not find anything. The only thing i noticed was the on the y-axis of the ghost touches the screen is fixed on the left and the right.
I check everything else closed the case ... but the ghost touches are still present.
Any idea how to fix the issue??? Who else realized the same issue???
Attached some screen shots from the touch test apps.

Sounds like you have a digitiser hardware issue to me. Had the same on my Surface RT. Only fix was to get it replaced.
Yeah, I just got mine back from warranty digitizer recalibration.
tapatalkin'
Another TF700T here that just returned from RMA with digitizer repair. Went very smoothly for me and I have a TF700T that again works extremely well.
Do they replace parts or just recalibration? Is it possible to so this myself?
I have unlocked bootloader and i do not know if they will repair it without any problem. Any experience on this?
Hi,
First, sorry for my english...
Second, I have same problem since saturday 24 august with my TF700T. Buy november 2012.
I tried to updated to android 4.2 But it didn't solve my pb.
I try "Multi Touch test" app and I observed same problem than mr_cg. Thanks for your good description "Ghost touch"
Ghost disappear when i unplug and re-plug dock, (some time two or three time) but just for some second ...

If you are root, you can perhaps try this app:
ILITEK Touch Utility
or
(less chance i think, it did for S2,S3) TouchScreenTune
Me i am not root, but if it is working for you, perhaps i will try to be.
Thanks for your help

Thanks for the hint. I tried the apps, but both do not solve my issues.
ILITEK ... descriptions sounds good, but unfortunately not working (i get always "access denied" even i have root for sure).
TouchScreenTune ... Based on description it should be also good tool to reduce/improve situation with ghost touches. Anyhow ... it is not working with TF700t.
I am just thinking if i should open the case again???
If with root permissions you don't find solution ... I think i should call Asus support for my first RMA..
snif snif.
Thanks for your return. I win a lot of time.
Same issue
I'm having the same issue here, but only when docked. Seems like I'll stop using the dock since I am out of waranty because I unlocked the bootloader ...:S
I've been having a similar issue very badly on the right side of my screen, it was practically unusable. I am also out of warranty because I'm unlocked. What I did to make it at least somewhat usable was go into the build prop and change my max touch screen events from 200 to 4, and changed my touch sensitivity from .001 to 1 (this setting may have only been available on CROMI. Anyway, now my touchscreen doesn't work on the right side, however it does work everywhere else, and most importantly I can still use the tab as a laptop in its dock. It's a bumm it doesn't work right, but it's better than a total loss!
Sorry guys, it is a failed design problem due to connection to the touch screen. see my post in the "so i took it apart" thread.
Cost me a ruined lcd screen to figure it out

What a great thread! Thanks, I've posted this elsewhere but having just send my TF700 back to ASUS I now have a pretty good idea of what might have been wrong with it. Here's what I posted and what I've told them anyway. I've overlooked the Ghost touches unfortunately, so I will let them know that (if they don't already)......any comments welcome...
Asus Transformer S/N D20KAS016975
I've struggled with this tablet since purchase in April this year, not being at all familiar with tablets I did not know whether it was just me, the general setup, or the tablet itself at fault. Most certainly the performance is not satisfactory. I have done three 'Factory Resets' and numerous Soft Resets.
Intermittently, the tablet will scroll and flash through various apps, when I open it. Originally File Manager would open itself up, then I got the feeling the Weather app would upset things. Sometimes a browser would make it do the same. Then I tried various Launchers, but the best of them (I think) sometimes shows the menu unannounced. Same thing, on and off until I intervene.
It is also prone to do this just sitting open by itself.
Clearing the caches sometimes fixes this. Sometimes this will stop by itself, other times I need to either close the lid, press the lock button, or turn it off. Then it will be OK.
At times Gmail will scroll randomly through the accounts, messages, labels etc.
Every browser I've tried will sometimes shut itself off, especially if I try to type something into a message box, usually when I've spent some time doing this!
Occasionally I can feel a slight tingling sensation when I'm lightly touching the back of the screen.
One other thing: When left overnight the mouse doesn't work and the tablet needs to be turned off and on again for the mouse to work. I also think the screen doesn't turn off sometimes (can see a light).
At other times the whole thing works just fine.
Hope this helps.
Regards
Grant
Tablet arrived back this morning

Tablet arrived back this morning and seems all OK. Report indicates they replaced the LCD panel (new) & replaced the touch controller board (also new). And did various tests. Good service I think, no fuss. I'll let you know how it's going in a few days.

Grant,
Was your tablet still under warranty? Did they charge anything? I wonder if they redesigned the digitizer connection or just put a new screen which will wear out as well. The digitizer connector runs along the bottom left of tablet screen. Same area is being pressed when you close dock, which wears it out.
You can go to developer settings and enable "show touches" (lowers tablet performance) then press on the bottom left edge of the screen, roughly 1/3 point of its length, and see if you get the ghosts to appear.

Yes, still under warranty (problem was there from day 1 although I didn't realise it at the time) and no charge. See attached pdf Customer report. Shows replacement Led panel, & controller board. No sign of ghost touches so far, and really working well actually. Early days yet, but I also note elsewhere in these forums someone mentioned their tablet not working properly 'upside down'. I neglected to mention it earlier but upside down isn't as funny as his respondents made out. I use mine often lying on the couch watching TV, with the tab upside down. Reason I mention it now is that mine acted up in those circumstances too. Anyway, that's fixed too.
Recently I've been having lock ups on my screen. The digitizer continues to work as if I keep typing during a text while this happens once it unfreezes everything I've typed will appear on screen. I also get some random graphical glitches kind of like the controller is failing. Anyone seen this behavior before? I'm hoping it is software but a hard reset hasn't corrected the problem, also I've not had any hard drops.
