My galaxy s6 turned itself off last night as I was using the just installed Domino's app. The battery was a little low, around 15%, but hadn't gone to 0% using the app.

It wouldn't respond to pressing the power button. When I charged it via micro usb with multiple different chargers that work with other devices fine, it shows the grey battery with a lightning bolt and doesn't change to the battery with green charge level.

I left it to charge for 20 minutes or so and when I tried to start it it gets to the "Samsung galaxy s6, powered by android" splash screen and then goes no further. After it getting stuck here multiple times I left it like that overnight to drain the battery to see if that would help.

I charged it with known good charger for 4 hours today.

Today I've tried vol up and power to force restart, vol down plus home plus power to get to OS install screen and then vol down to cancel and restart phone.

I've tried vol up plus home plus power to try and get to start in safe mode or wipe cache, but it doesn't do anything when I try to press those three buttons together...

Any ideas on anything else to try before admitting defeat and sending it back to Amazon.de?

Cheers guys.

I can get to download manager okay to install a ROM if needed - if I install the newest official samsung firmware is it going to increase the knox counter/invalidate warranty?
