How to wake up my non responding Samsung Galaxy S7 EDGE?

[mia005]

Hi everyone,

My Samsung Galaxy S7 Edge suddenly stop working.
First time, my mom was calling me and she listen that its ringing to me, and my phone is with black screen, no ringing activity.
I pushed buttons to restart - wasn`t working. Than I pushed all buttons, I don`t know what and it start on.
I use my phone, that half hour later I also see that it doesnt work.
No reason.
Tried again to restart, I try all options:
Power button + home
Home + low volume
Power + volume + home.... All possible combinations and nothing.

I plug in charger - no reaction.

Now I try to call myself from other phone and it says I`m not available.

Any idea what to do?
I know I can get it to service, but I want to resolve myself.
I need to safe my data.

PLEASE HELP

Welcome to Android Central! Plug it into a wall outlet and let it charge for at least 4-6 hrs. Then press and hold Power for at least 15 seconds. Does it turn on?
