Xperia Z Touchscreen troubles

[themichelanne]

Hi,

Lately i am experiencing a lot of troubles while typing a message or just unlocking my lockscreen.
The touchscreen respods bad, sometimes it starts moving out of itsselve... Its really annoying to work with the phone like that...

Someone facing the same problems?
Suggestions? Fixes?

Btw. The phone is stock, nothing changed or replaced...
The onling thing i did was removing the shaterproof film (and my Sony logo )

Try repairing it with Sony's PC Companion or Sony's Update Service first.
remember to backup your stuff before proceeding.
Do full wipes.

Did you try to shut the phone down for 30 seconds and restarting it, seems to fix many unusual android issues.

I have noticed sometimes that my phone on the odd occasion does not repsond to screen press.

I've had this problem only sometimes when charging outside...When u feel that the touch isn't working as it should,put on your earphones and look out for a low buzzing sound..if u hear anything,then unplug the charger from the wall and check in another socket..hopefully the problem in my phone was that current was leaching onto the capacitive screen so if I touch just once,it registers a number of touches..hope this helps u get rid of the problem

Hit thanks if I helped u.Sent from my Killer Xperia Z(C6602) using xda premium.

That may be the solution to the problem you had but this isnt the problem here , it happens when whether the phone is charging or not and I think themichelanne is having the same problem.

Power off the phone with power+ vol up - wait for 1 vibrate followed by 3 vibrates and leave the phone then wait for 30 second before powering on, solved it for me....no problem in touch till now and i hope it does not come in future.

BTW This phone is really really full of problems.

Also happens to me when using some chargers

I bought my unbranded UK Xperia Z in Expansys, since I live in Portugal they sent a extra charger for the european standard socket. I had this exact same problem with it, the screen was extremely unresponsive and unprecise while charging. Now I use the charger from my old N900 and have no issues. Also, charging from a lower volt/amperage source like a computer I have no problems.

Since the capacitive screen is very sensitive, a low quality AC-DC adapter will generate issues (possibly due to the current/voltage not being 100% stable).

Could be a bad screen protector.

me too

Im also experiencing the same problem. So annoying, especially while texting. Xperia Z's touch not proving to be how it should be.

This happens with this phone for me, and previous android phones. Usually its just the app open not responding to touch events, but my softkeys still work and I can force kill and restart whatever im doing. Sometimes I have to reset. It seems to be happening more frequently since updating to 67, but its not often enough really bother me. using a tool like romtoolbox to increase the amount of touch events android can process seems to improve it somewhat.

Have you found any solutions for this? I have been experiencing this since 4.2.2 update. I don't know what happened. Can you please explain what's wrong and what's happening? Have you got it fixed yet? My screen freezes frequently so I'm unable to use the phone.

I have been experiencing this problem since a long time. But I have found no solutions for it. I took out my screen protector and the freezing thing got to normal but still it freezes sometime, but more when the screen protector is on. I'm pretty sure this problem is caused by the screen or the android farmware. I'm downgrading my OS, please reply to this. Mine is C6602. C6603 doesn't experience any problems like that.

How I fixed my Xperia Z5 touch screen

Hi everyone,

So, my Z5 touch screen was not working at all anymore, I have tried every manipulation recommended on the internet but did not succeed to get it working that way.

Here is what I did to get it fixed eventually:
- Installed sony companion
- Launched the "fix software" program (I don't know the exact name of the program in english)
- Followed the steps (took a while, something like two hours)

Then my phone rebooted, but nothing, still the same issue. Tried taking off the sim card, rebooted and same problem. Then, I put it back in the phone, and for some reason, the touch screen decided to work again. Although, I lost a lot of data in the process, but worth it.

I don't know if it is a general fix, but on my phone it just worked that way. Although, I have noticed that my phone started overheating something like two weeks before the touch screen problem appeared, I assume those two problems are linked in some way. Still did not find any fix for the overheating problem except putting it under cool water or let it cool down for 10 minutes.

I hope I helped with my post, good luck for those who are experiencing this issue.
