Notification bar and bottom buttons not working

[Maje]

Hi, I have been having a problem with my Sony Xperia Z3 Compact. For some reason it won't allow me to pull down the notification bar anymore. And since yesterday the bottom buttons have also stopped functioning. I can't really exit any app and the phone has become pretty much unusable. Does anyone know a solution for this issue? Would this fall under the warranty that comes with the phone?

I already tried a factory reset but it does nothing the solve the issue.

Thanks in advance

Does your phone has a protective case and/or film?

1. Settings
2. About phone
3. Diagnostics
4. Test
5. Test the screen

Yes, I have a protective case around the back. No extra film apart from the standard one that came with the phone.

The touchscreen test failed because the top and bottom of the image could not be cleared

@Maje

Follow @Phy's advice, if that doesn't work, remove the case and film and test it again.

The test still fails after removing case and film

Try repairing your phone with Sony PC Companion and Check if that works.

Hi @Maje,

I also suggest that you try the software repair using PC Companion.

In PC Companion you press start on "Support Zone" > Start on "Update the phone/tablet software" > "Repair phone/tablet" (the blue clickable link in the message) > Follow these steps without having your device connected to the PC.

Follow the instruction that appears in the program and do not connect your device until this guide tells you how to connect it.

The software repair will remove all data stored in the phone so don't forget to make a backup in PC Companion before you try the software repair. You can do a backup using the Backup & Restore option in PC Companion.

I had already tried the PC Companion repair to no avail. I am bringing it down to the repair centre today.

Thanks for the help everyone
