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!!

Sorry for not using better thread name, because i don't know how to phrase it.
Anyway, the problem started few months ago. When I unlock the phone, it randomly starts pressing in the down left/right corner, or when trying to type, presses random buttons (like when i press k keyboard goes crazy and starts typing aaassaadaa). The thing is, it happens randomly(usually after i haven't used phone for a while) and after 2-5 mins it works normally.
I don't believe that it's software problem because it happened also on 1.6 and I did 2 soft repairs. But if it is hardware problem, why does it happen so randomly?
Also the phone has fell twice and has 2 cracks in the screen, but they are in the upper part of the screen.
this is random but, the touchscreen stops responding occasionally
specifically when i'm playing Mario Kart and holding the A button in for extended periods of time (n64oid)
it's not even when the system is hot it's really peculiar
actually now that i think about it this has happened a few times when i was on my homescreen as well where the touchscreen decided to stop responding yet if i pushed the buttons it still operated
anyone else seen this?
i was hoping it was ram related because i just used bloat freezer and cleaned up the ram nicely
The original X2 i had did this extremely often right out of the box (activation was a PITA)... as in it would work for 5-10 seconds (30 if i was lucky) and the touchscreen would "freeze" while all buttons and everything else were working as normal. Power button to make screen go off/on fixed it, but it would just happen 10 seconds later. Idk how bad yours is but if it is common enough see about a replacement (or hope OTA comes soon and fixes it for ya)
I'm Not Sure What It's Related To, Because I Can't Replicate It To A Certain Time Or Point Sometimes When Opening An App It Doesn't Recognize I Tapped The Icon Or When Texting Sometimes It Doesn't Know I Was Touching The Screen. Could Be Just Another Bug In The Software Which We Hope In The Future Will Be Resolved.
Its got the same feature as the atrix if one screen is pressed for more than 20secs in the same spot the screen turns off. Motorola claims to do this to protect against water damage
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!
I have weird problem with my phone.
First i need to note that, the phone has third screen mounted for now. I have that problem on all 3 screens. Original screen had this problem, then i changed it after cracking screen. After one month i cracked second screen and last day i mounted new screen. The problem is - sometimes (maybe 1-5 times per day) touch (i mean screen + hwkeys on it) is unresponsive until reboot. Touch is never hanging up when is turned on. I doesn't have ghost touch or sometimes like this. Touch is turning off always when i unlock phone with key or fingerprint and i need to reboot device with pressing power. Then it's always working fine.
Anyone has that problem? It's my second lemax because i sell first after problem with camera (no focus, hardware damaged because when i shocked phone it's sometimes started working). Sorry for my bads.
What i tried:
-flashing new firmware (but i dont remember what firmware i have now)
-flashing new custom rom
-flashing phone in 9008 (i need to do that after changing fingerprint sensor)
-changing screen because i cracked two (problem is on 3 screens)
-noted that problem is always. Nothing matter with phone temperature or cracks.
I have hotair and i can reflow IC but i don't know which IC can be damaged.
Hello,
I really hope someone could help me.
My phone's touchscreen is becoming unresponsive at random times but mostly if the phone is not being used and I'm moving(in my pocket). The display works fine, if I am pressing lock twice, for example, the camera app pops but I am not able to press the caption button.
This issue is resolved if I restart the phone (volume down and lock button), but after a few minutes it becomes unresponsive again.
Also I noticed that the battery drains way faster.
This is how I tried so far to solve the issue:
-delete recent downloaded apps
-start the phone in safe mode
-reset factory the phone
This issue started at the end of quite very high altitude, not sure if this could be related.
Help would be really much appreciated, currently backpacking and don't afford a new phone or spending loads of money on repairing.
Thank you
A SEU is possible. Rare but more common at high altitudes. Try reflashing to same version firmware. A hardware failure be more likely nonetheless you need the eliminate corrupted firmware as a possible cause. If under warranty, send it in.
Try downloading UsbMode.apk
It will report your touches, also mutltiple touches.
(Ok, Developer Options in Settings has a variant of this too.)
A family member had this problem too - I ended up sending it to my carrier for repair. Hopefully yours is still under warranty if it's the same issue.

From Romania, not yet. Can't really take it to a workshop where I am, so I have to wait for another couple of days
Keep me posted
I hope it gets fixed
