How can i fix my S7 Edge Duos always Restarting without warning?

[AC Question]

Hi All,
I am New to this forum, Last Couple of Month I've been using my new S7 Edge Duos Phone, the phone came with Android 7.0 (Nougat) version.. and it worked smoothly without any problems, but since last week it started to malfunctioning which means normally i kept my phone in [Mid Power Saving Mode] but the phone indicators Backlight buttons were started to lit up also the phone started to reboots time to time without any warning.
So I have also tried factory resets, wiping the cache and app memory to solve this problem nothing will stop this issue.
Anyone can help me?

Welcome to Android Central! Try booting into Safe Mode and see if the restarts still happen. If not, then something you installed is probably causing the instability. Uninstall apps one by one until the problem goes away.
