[Xperia Z3 Compact Q&A, Help & Troubleshooting] adamk7:
TLDR: I was cuddling my gf to sleep while using my phone. I fell asleep too. The phone was in bed with us for a couple of hours, but I don't think either of us lay on it, though my gf may have put some weight on it while getting up from bed to go to the w/c.

This morning it was unresponsive to touch, after rebooting it twice it won't turn on at all :(

When I press on the screen 1/3 of the way down with a bit of force, I feel it moving a bit and I can hear and feel a click on the inside.

The glass is intact.

I fell asleep with the phone in my hand and I must have let go of it in my sleep. I woke up when my girlfriend was going to the bathroom in the middle of the night. The phone was still in the bed near where my hand was when I was falling asleep, but it was also in the path of my half asleep girlfriend rolling out of bed. I checked to see if it was still alive by pressing the power button and the screen turned on. Satisfied, I put it on my nightstand and went back to sleep.

When I woke up this morning I tried using it. It wasn't responding to touch at all, not even the home row buttons. But the volume rocker worked and so did the power button menu, but I couldn't select reboot in the menu with the touch not working. I force closed it with power + volume up, and when it rebooted it still wouldn't respond to touch. I force closed it again and now it won't turn on at all. I tried numerous button combinations (power on + volume up, down, all three, holding for up to 20 seconds) and it doesn't respond to being plugged into the wall or to the computer either, no led light and it's not mounting on the PC. It had about 60% power left before force closing it.

The funny thing is is that I couldn't figure out what the cause was for a long time. I googled it and search results for Z1's "sudden death issue" appeared and I figured it was something like that. Or maybe it was a delayed effect of putting it underwater 2 days ago.

But then it dawned on me, it was (of course) what had happened in the middle of the night. The phone looks completely fine, but after examining it closer, when I press on the screen 1/3 of the way down with a bit of force, I feel it moving a bit and I can hear and feel a click on the inside. I wonder what that could be..

What are my options now? I got the phone just a couple of days ago. I doubt this is covered by warrenty right? User error?

I'm not sure if this is even the real cause though - I didn't see it happen.... but I guess it's the most logical explination.

My girlfriend is pretty small so I'd imagine she would have had to put all her weight on her hand or elbow when she was getting up to be able to break the phone like that. I have a foam mattress which probably absorbed a lot of the weight? If this is indeed the case, I'm a little disappointed in the build quality if this broke something in the phone's innards with relative ease.

Any advice would be appreciated. It's the UK model bought outside of the UK from a local retailer. This is my first good smartphone and I loved it for the short time we had together. I'm devistated about it and not really sure what to do next.

Someone hold me :(
