Since a few days my Archos 101 G9 has got this problem.
I activate the device and want to unlock it.
It looks like something on the left side is touching the screen.
Tablet is active, but the back-'button' on the lower left hand is blinking like someone is tapping it.
Programs won't run, the back does really work.
After a few minutes the blinking stops and the tablet works as it should.
I tried cleaning the touchscreen (dry cloth), took a small peace of paper between the edges to remove any dirt there.
But still this problem occurs.
Updated and reset to factory yesterday.
Firmware : 4.0.28 (Android 4.0.4)
Board : A101S-V5
OMAP : OMAP4430 ES2.3
BOOT : Unkown / 5.05.000009 - C0x00
Smallband : Unknown
Build : IMM76D
Try to recalibrate touchscreen 10-15 times.
If it will not help - then you have to RMA your tablet, I think.

The digitizer on my HTC One X+ seems to be unresponsive on some strips of the screen.
This problem occurred after I replaced the lcd+digitizer module because the original one was cracked.
First 1 strip of the digitizer didn't work but 1 week later there were 3 unresponsive strips.
Today I reopened the phone to check if the new screen was the problem but after putting the old cracked screen back, it showed the same unresponsiveness but on different strips. I added a screenshot of a draw test in the attachment (since I can't post images from outside links).
On this screenshot, all 5 strips of the bottom half of the screen are unresponsive but sometimes only 2 or 3 strips don't work.
I notice that the screen freezes sometimes while trying to unlock the phone (which is a pain currently). Also the phone gets really slow and sometimes it randomly registers touch all over screen while I don't even hold it.
So my question: Is this a hardware or software problem? and does anyone have an idea how to fix this?
On the side, another problem: when I try to update the phone's firmware I get a notification that a new update is available (this is a very old update from months ago) but when I try to update it, the phone reboots, tries to install the software and then a red question mark appears on the screen. I haven't been able to update the phone for about 4 months now. Don't know if that has anything to do with my current problem but I thought maybe I should mention it.
Thanks in advance.
This may be because of the bad connection between mainboard and the touch module.
If you can , pull apart your phone and check the cable that connects the digitizer. Also, clean out cable's jack and cable's fingers.
As i am new, i cannot post imgs/ links.Search on youtube for "one x screen/ digitizer replacement" and follow step by step instructions.
Hello! So my Xperia Mini pro has been broken, it doesn't show any image anymore, I think there is a problem with the screen but I want a confirmation or recommendation to find out what the problem is.
First the screen "touch" capability stopped working, and then two weeks after that, the back and option buttons stopped working too. And a week after that ,there was like a screen "flickering" (I tried to recreate the problem in the attached image) when I tried to either open or close the slider.
Finally the screen stopped working anymore. I tried to connect the phone to the PC but says that windows cannot recognize the hardware. And there's one more thing: I can turn on the phone, it vibrates, but the keyboard lights seems that are not working, they are permanently off.. and when I try to Increase the volume it doesn't sound either... There is only the black screen and a backlight.
Please Help me to find out what is the problem, I'm thinking to buy a screen replacement on eBay, but some people told me that is the "flex" cable. I'm not sure if there is a fix for my phone's problem.
Thanks!
Hey there.
Based on my experience, yes, your problem is most likey a flex ribbon issue. Your flex has been ripping apart lately, causing many of its wires to break. This can cause a lot of unpredictable problems, such as a misbeheaving notification LED, inactive ambient light sensor, or "dead" display/touch digitizer. Your problems have gotten worse over time, which is clearly a symptom of a broken flex.
You phone is no longer booting up to android because the kernel no longer detects a proper "response" from the display driver and halts the bootup. This is why you can feel the phone vibrating when pressing the power button, but nothing else happens. Your screen assembly is fine, I can assure you that, unless your glass is broken, of course.
Here's one hell of a good teardown guide: http://www.ifixit.com/Teardown/Sony+Ericsson+Xperia+Mini+Pro+SK17i+Teardown/7275
I used that very same guide when I repaired my own xmp. I regret messing with my screen assembly because I destroyed it and had to buy a new one, which is costly
Thank You so much for the advice ! Now I'll try to repair it, It doesn't seem too difficult. Thank You Again!!!
Xperia Ray user:
I think my ray has sporadic display coma issues.
it seems to happen when phone comes out of deep sleep (standby for a minute or longer) and i press home or power button to play with it. The backlight lits up, but the GPU doesn't seem to come out of its sleep (=coma?) and screen stays black with backlight on. The phone is then fully functional, also touchscreen works well....but without display output.
Only way to wake the screen up is to press the power button repeatedly (press twice fast (=off/on)...nothing..wait a second press twice fast...repeat until screen is on)
I tried "every rom/kernel" out here (incl. factory resets), no simm, no sdcard etc. , also added wakelocks to keep the device out of deep sleep..and the only thing which works best for me is to use cyanogenmod 7.2 (GB). It smells like a hardware problem on the qualcomm chip with its embedded GPU.
Somehow cyanogenmod has a different approach on switching on the screen?
Still when making phonecalls with CM 7.2 and screen goes off by proximity sensor...the coma issue comes back (black screen) and i cannot put the call on hook as i dont see anything on screen.
If anybody knows a low-level tweak (deeper than kernel goes), please PM me and write a reply.
Sorry... i refuse to accept that out of nothing this screen coma issue pops up...and when i finally have the display on...everything works fine.
Thanks in advance

My 2 friends have xperia ray and both of them are facing the same issue, this issue started to show up after disassembling the phone
for changing the housing.
Did you disassembled your phone or gave it for reapir where they disassembled it?
sometimes the touch screen also stops working but its happens rarely.
I don't think its an hardware problem because it only showed up after disassembling the phone, i think the housing or the touchscreen
cable becomes loose after disassembling because i kept some packing of paper over the touchscreen cable and its sometimes solves the problem but still happens!
I went to sony care they disassembled the phone and found nothing bad inside and told me it may be a software problem but ever since they
disassembled and reassembled the phone the issue magically disappeared!!!! but one of my friend is still facing the issue.
So its can be a loose screws or housing!
Hello,
I got a really weird issue with my samsung galaxy s5(SM-G900F). Out of nowhere my screen wont display anything anymore when i booted it this morning.
I did let it fall like 2 months ago and has a little crack but only in the top layer and nothing happened last night to my phone, no water damage either( also since its waterproof).
Even though i cant see anything, its still responsive. I've tested it with Vysor( screen mirroring software). Now the weird thing is that in Vysor first of all the resolution is messed up, and the region of my android seems to be horizontal in the top of my screen, with left being the top and the right side being the bottom. I've tested this by simply touching the screen in my lock screen and seeing where the bubbles would pop up.
[cant post image links apparently because i dont have 10 posts. can i add an attachment somehow?]
Additional information: My phone is rooted since a few days and I had installed xposed framework, didnt boot after that so uninstalled it in recovery mode and that was the end of that, was working fine again. Since then i had already rebooted many times without problems. Also sometimes when i restart i see a thin horizontal line in the top of my screen flickering for about 0.2 sec. Led, buttons and sound are all working fine.
Anyone seen this problem before and what could be the fix? I'd rather keep re-installing the firmware as a last resort as I can still use WhatsApp in my browser(my main communication method) and also not get my screen repaired for €150 untill im sure about the cause.
Thanks in advance.
Hello Everyone,
I bought my cousin's xperia z2 two days ago its a great piece but so bad for me i couldn't enjoy a full week without problems
the screen becomes unresponsive when i hold two fingers for some time (15-30 seconds), I've discovered this issue when I was playing GTA San Andreas and kept holding the screen, during normal use this issue happens very rarely, but I think what's causing it is when i hold two fingers for some time it becomes unresponsive (tried it on home and other apps its not related to a specific app), locking/unlocking the device fix the issue and everything goes back to normal till i hold two fingers again........ its really irritating and i don't know what to do.
I've tried to boot into safe mode and the issue stills there and I really can't tell whether it's a software or hardware issue .
About the phone :
- Hardware : it has a replaced display and vibrator not working
- Software : no system changes have been made, everything is stock!!
