Touch screen problem on specific area when device is unlocked

Since that is a weird issue & after searching a lot of times i don't get a proper solution, i think that is the time to post it.

 

Touch not working on top notification bar & bottom menu(home, back) bar when device is unlocked. But that is working perfectly when device is locked(on lock-screen).

 

I already test screen by Xperia Diagnostics, every area of screen working fine.

So, of course that is not a Hardware issue. I already tried with Downgrading to kitkat but that doesn't help.

 

Thanks in advance Slightly smiling Face

Might be one of your apps? Try safe mode.

Hi arifkpi, welcome to the community!

 

I agree with @Quester on this. Boot the phone in Safe Mode, if the issue was not present in Safe Mode, that indicates it is a third party app causing the issue. In this case exit Safe Mode and then un-install any third party apps you don't need and clear the cache/data for the apps you want to keep. If this doesn't help or you have found that the issue was still present in Safe Mode - you will need to run a software repair on the handset.

Re: Touch screen problem on specific area when device is unlocked

Hi arifkpi, I am sorry to hear that. I advise running a software repair on the handset as that is likely to resolve the issue. If it doesn't then I advise contacting your local Sony Xperia Customer Care team asap to get the handset inspected.

 

Here's how to run a software repair using PC Companion.

 

Open PC Companion > click Start under Backup & Restore to back up data. Once complete, disconnect and power off the phone. Press Start under Support Zone > Phone/Tablet software update > Repair my phone/tablet > Continue > Accept data removal > Next > Wait for prepare > Select model of phone > Follow the connection steps. 

 

I do hope this helps, let us know how you get on.
