My back button and my home button are not working anymore

Pablo951 — Sat, 31 Dec 2016 15:30:53 GMT

This morning my home/back-button suddenly stopped working :(. Phone is in pristine condition, no cracks or what so ever. If I'm into any app, everything works perfectly fine - but if I want to switch app, I have to restart the phone. I googled the issue, found nothing :(. Did I switch something by accident or whatcould cause anything like that?

Swipe function, camera or mic works fine when the phone is locked. But as soon it's unlocked the arrow of the back button turns down (not left) and the home button just doesn't care anymore...

Test the phone in >>> safe mode

also, settings > about phone > diagnostics > test > test touchscreen > report back.

Thx a lot. Didn't work out unfortunately. Think I have to restore it in another way.

Touchscreen test worked out fine, everything alright. I then tried to do a software fix via the suggested xperia tool - nothing changed. I think I have to switch Phone since this seems to be broken somehow...

Sorry to hear that, but you are correct, you should contact your Local support to get it inspected.

WIth "software fix" you mean that you did the "repair phone" with Xperia Companion? Getting the phone as if it was brand new?

If not it might not be an hardware issue. They are soft buttons after all. If the screen works fine it could be an issue in some (system) app. Have you tried enabling the rotation in Xperia Home (hold the finger in the wallpaper, click settings in the bottom right and then enable the rotation) and see if in landscape mode you get the same issue?

Also any custom theme, or if you have Xperia Home beta installed could affect these buttons. But if the phone has been reset indeed to factory settings I don't see any other solution than to bring it to Sony support.

Yes, exactly. It was Companion. Sorry, I was to lazy to switch of my phone just to look up the name of the software tool. I don't think it comes from a third party app, since the bug still exists in safe mode. Seems really the only solution to bring it to the sony support...

But still, I can't explain how that error occured. Since I was in the middle of a whatsapp-convo.

But thanks for your reply. Have a great day.

My touchscreen doesn't function well on the upper and lower part of the screen. I have to enable the glove mode function to be able to get the lower part of screen functioning. But the upper part is still unresponsive

I think your touchscreen is broken. I had the same issue with my Z3 Compact. Started with the 3 buttons "Back, Home and Recent Apps". After That the upper edge went dead, so swiping down for notifications and quick setting didn't work no more. There is a work around with apps like Simple Buttons were you can put the buttons on any side of the screen. This works perfect because these buttons are from a third party app and therefore (I believe) placed on a different layer. Because, why is the screen working properly in apps, while the native buttons stop working?
Software repair or reinstalling doesn't resolve the problem.
The other solution is to the get your phone to a repair center. I think you will end up with this scenario. That's why I ended up with a X Compact. As a replacement for my beloved Z3 Compact.
On this forum, but in the Z3 Compact section, there are several threads about this issue.
Good luck.

Same problem.Worked well for two years. Never again Sony. Such a pity to see such an illustrious name fall to the same level as the cheapest crap out there.
