Hi. This morning my S6 edge turned itself off when it was in my pocket. When I tried to power it back on, it got stuck at the "Samsung Galaxy S6 edge Powered by Android" screen and has been ever since. Holding down the power button does nothing. Holding the power button and volume down together briefly causes the screen to go blank but then it gets stuck again at the same screen. I can't get into recovery or boot in safe mode.
Haha long time ago now, but sadly there was no solution. I took it to a Samsung store and they said it would have to be sent off for repair and would be wiped in the process. I ended up going through my insurance instead for a replacement. Three years later and now I have an iPhone!
