z5c Back Button, Home Button not responsive

zero_vertical — Thu, 18 Feb 2016 04:04:56 GMT

Suddenly today, all my lower screen buttons (back, home, drawer) are completely unresponsive. Multiple restarts.

sD card was getting full, so cleared a bunch out.

Battery was at 60% or so.

Installed a new app this morning (voice recorder), but cleared cache and deleted it.

Would hate to factory reset this thing. Not even sure how to do it. What are my options?

Before you repair the phone, you could test the touchscreen.

1. Settings
2. About phone
3. Test
4. Test the touchscreen

You can also test if you encounter the same problems while on safe mode.

Booted into safe mode (holding "-" volume key until I got to home screen. safe mode tag is visible in lower left.

Back, Home and Drawer buttons still not working.

Tested touchscreen. All of it worked but the bottonm strip where the button are. It failed by timing out (because I couldn't press no!)

Contact your local Sony Xperia support it seems to be a hardware issue.

I bought a non-US release months ago, because I wasn't sure it was going to make it stateside.

I don't think I'm going to be welcomed by anyone for a service issue.

Love this phone. What happened this afternoon!!?

Have you repaired the phone with PCC as suggested above?

So I was on the way into work yesterday, planning to factory reset the phone, when the sun caught the lower corner of the phone and a hairline crack gleamed at me.

Turns out, there is an almost invisible crack in the lower corner from the bottom terminating at the side, exactly at the top of the black navigation bar.

New screen is $200, but parts are 3-4 weeks out. I can't wait that long, so I bought a new one. I'll just repair this one and keep it as a backup. In the meantime, the app "back button" has kept hte phone pretty functional. It's just a customizable widget that floats on top of whatever you're working on, and has a home, back and recent (drawer) button.

Thanks to all for your help!

Anytime, you can also use a USB OTG cable and a regular mouse

Hi same issue with mine as of yesterday. However, attempting safe mode, then software repair, the issue persists.

Diagnostic touch test passed.

Also when waking phone from sleep the camera and microphone short cuts are responding which are in the exact same place as the home, back buttons etc.

Will try this floating back app as a work around but this is pretty bad Sony.

Any help would be appreciated. Otherwise it's been a great phone.
