My s7 has been stuck on the loading screen for the past 2 days. I turned it off to charge it, then went to turn it back on after a few hours and it got stuck on the "Samsung galaxy s7" turn on screen. It's been like this for 2 days.
When pressing VOLUME DOWN + POWER, the screen turns off then turns back on again, just to get stuck on the same loading screen again.
