I just obtained a Galaxy Tab 10.1 for a very good price, but the touchscreen registers touches without me touching it. This was even with CWM Touch Recovery installed (had to go with the regular CWM Recovery). Is this a digitizer issue?
Which ROM were you on?
Touchscreen Tune is a great app to fix screen sensibility if you haven't tried it out get.

I have only ran stock ROM, and CleanROM. I also ran that app. It has a portion where you can test the touch sensitivity, and it was registering like 5 touches with me just holding it...even with it laying on the table. The app didn't help in this case.
Plus with it doing it in CWM Touch Recovery, I don't think it's a software issue. I'm more so wondering if it's the digitizer or does anyone think the touch controller is bad?
I have never tried CWM Touch, so I would not know any experience you are having, sorry! Hope someone can help you, though.
I wonder what effect dirt/dust under the screen has on phantom touches?

I just bought a archos 101 g9 when it was on sale on woot last week and so far it is working pretty good, however I have an annoying problem with it.
If it has been sleeping for over a few minutes (regular sleep, not the deep sleep) and I wake it back up the touch screen goes crazy. The bottom left corner keeps detecting a touch event. It will cycle from multiple on/off touches a second to one on/off every few seconds. If I rotate the tablet to portrait, it will start scrolling the screen none stop to the left. So far the only fix is to do a reboot.
It does not happen every time, just occasionally when I wake it up from sleep.
Today i got a case for it, and whenever it is in the case, the touch screen goes crazy. Same touch events in that same area.
I am guessing something is wrong with the digitizer. Anyone else seen this problem before?
Have the same problem, and as I've read on xda and archosfans forums, this isn't an uncommon issue. We'll just have to wait for a firmware update, as rebooting seems to fix it, so it doesn't seem to be a hardware problem.

I have exactly the same problems.
@ARCHOS: PLEASE FIX THIS PROBLEM. THIS IS A SERIOUS BUG !
Sensitive Touch
I have similar problems with the touchscreen. If I'm holding it with one hand by a corner, it detects touch. The rest of the time it is a little jittery and releases or double taps in games. It's still not a deal breaker, though.
I hope we don't have to swap digitizers to fix it.
Hi !
Me too
...works fine after Touch Screen Calibrate , but the next reboot do the same !

I'll give that a try and see if that works. I just got a case and as soon as it is in the case it is even worse.
EDIT: I installed a calibration app on xda and it really made it worse!
What app are you using to calibrate it?
I have a similar issue sometimes.
For me the fix is simply to clean the screen.
The strange thing is, it happens even when the screen doesn't appear to be especially dirty but I put the tablet to sleep, give the screen a serious clean with a microfibre cloth and the touchscreen issues vanish.
Could be a different issue to what you guys are having but the symptoms are the same and it's an easy 'fix' to try.
Hope it helps.

Use the inbuilt one, Settings > Repair & formatting > Touch screen calibration.

Thanks, I had not noticed that area in the settings before. Recalibrating it in the cover has helped a lot.
I pretty much had this since day 1......
The current state is ; it doesn't work at all then all of a sudden It will pop back into life and then pretty much go "mental" as already described, I also found it reacts poorly to minor temperature variations, i.e going from outside to inside and general day to day travelling. Recalibrating used to "help" but now has no effect.
From watching the debug logs part of me thinks it's a bit of both, hardware and software ( just a hunch ) I noticed the driver fail to get a "ping" response from the hardware a couple of times.
I've pratically given up on it myself and plugged a keyboard and mouse in via a hub on the full size usb...... The hub has now stopped working for some reason , I'm now on a OTG Keyboard with a Virtual Mouse Driver using the numeric keypad and some adb input trickery ,
I've got another touch screen/digitizer to plug in, just not got round to putting it in yet and a little part of me is starting to enjoy finding more elaborate ways of interacting with the device... :laugh:
Does anyone know who the OEM of the digitizer Unit is? My previous investigation led me to china but information seems to be thin on the ground with this one

Same problem and even managed a RMA from ARCHOS. Thing is your OC edition fixed it for me.
I had rooted the phone and was working all fine. I took it to a store to get the scratch protector installed on my screen and since then it stopped working. The hardware buttons at the bottom are all working fine. I can power up the device. I can reinstall roms but cannot do anything beyond that. anyone have solution for this. I read somewhere that there is some sensor for touch screen enable/disable. Please help. i tried almost everything
So isn't the "scratch protector" the culprit?

I removed the scratch protector screen. still the same problem.
Probably worth going back to the shop you went to? It would be my first port of call...
it happens to me too! the touch screen sensor is broke so you have to go to samsung service to fix it
Hi everybody,
Recently I've been encountering a problem where my streak won't respond to any touches after I open the screen. Pressing the power button and waking the phone up again does not solve the problem. I've read about the static issue, but unfortunately it doesn't seem to be the case here as the problem still occurs even when my streak isn't in my pocket.
Oddly enough, rebooting the phone solves the issue temporarily. The touchscreen will work perfectly until I turn the screen off again, but when I turn the screen back on, the phone doesn't seem to register any touches. The phone itself works fine as it still receives notifications even when the touchscreen is unresponsive.
Is this a hardware or a software issue?
I'm currently on DSC 2.2 and baseband 366. I'm going to try a factory reset right now to see if any will improve.
Thanks!
Edit: did a factory reset, problem is still occurring
I have the same problem, does anyone know how to fix this? thanks

Have you tried recalibrating your touch screen from the dell menu?
Its option 3, worked for me a few days ago.

Yeah I have. I'm currently assuming it's a hardware issue since I've reverted back to a stock rom along with several other custom roms but the touchscreen still remained unresponsive after waking it up. I'm hypothesizing its a bad connection somewhere, especially if the display and touch sensor wake up separately. Does anybody know anything about this and whether it can be repaired?
On the other hand, I might be completely wrong...
I noticed that some bags for DS5 produce static electricity, such as the original Dell Bag (Futon bag - ?)
The Leather Bag (with red fissure) does not produce static electricity even when having the DS5 in trousers.

I had this problem once, pried and screwed the Streak open, checked connection ribbons, and cleaned it with (a little bit) electric contact spray. This has saved my irresponsive power button as well! Success:good:
Hi all. My evos touchscreen is probably dying. Sometimes my screen goes crazy and doesnt react to touches. When I enable "visible" touches, one or more are visible on the bottom of screen. When I turn off and turn on display, everything is OK (sometimes not). Any solution? thx. ps.: i tried many roms.

Knoen Evo problem - faulty digitizer. Only solution is to change your digitizer.
thanx
They have the same problem. -> http://forum.xda-developers.com/showthread.php?t=2747330
I dont think so, its digitizer trouble...
It is something with kernel, the screen is normal with some kernels but even with ics roms mirage kernel has got touch problem I am not a developer so I realy don't know to solve this problem
If any can help will be realy good
Prob
I sometimes hae the same issue, screen just doesn't respond?:cyclops:
I have a very irritating problem my device touch screen is responding even though it is black and locked. It keeps annoying me when i am in a call and it is only a matter of time till it ends the call. Problem started after having a screen replacement but i can hardly believe it is a screen problem because it is functioning normally and also gets dark when i am in a call. My proximity sensor is working as it should. It is like my screen gets dark and not totally off.
My phone is rooted and i am running lollipop 5.1.1 custom rom

It sounds like you are having ghost touch problem. This usually presents itself when you change the front glass with digitizer and leave the old LCD. This cannot be repaired if this is the case. I dont think this is a sw problem. When did this issue started to manifest itself? Right after the screen replacement or it started to appeare gradually?
Yes it appeared just after repairing the cracked screen. The lcd was working but not the touch and the glass was all cracked.
How can i solve this?

One thing to mention is that i do not get touches that i didn't make. They are just getting read when the screen shouldn't read them.

But does touch work normally when you use the phone? Ghost touch can manifest itself on various ways, like your case or can go completely crazy when the screen is on. You can try some apps that resolve ghost touch like touch fixer. Some people are saying that unlocking BL and flashing CM resolves this issue and other sollutions you can try is to apply heat with heat gun or hair drier directly on the screen to make sure the glue is sticking the digitizer onto the LCD propperly, or fiddle with the flat cable contacts bit by bit until the touch is working properly but this requires disassembling the device again. You can alway try to flash different firmware to see if it'll resolve your issue but I highly doubt it will. GL
