(HELP!!! IMPORTANT!!!) S7 (G930F) restarts in weird times automatically

[DJ_Ben_Lord]

So today I was experiencing some issues with my WiFi (On every device I had, including my S7), so I checked my S7, if WiFi works. I opened YouTube to check WiFi. It didn't quite load any videos, so I was on closing YT, but when I opened the recent apps tab. That's where the issue is. THE PHONE'S SCREEN WENT BLACK AND IT RESTARTED. When it finished restarting, I did the same thing, opened the YT app, and opened the recent apps tab from it. It did the same. Next time when I did it, there was magically WiFi on it and it didn't crash, but some time later. IT HAPPENED AGAIN. Now I turned the phone off. Has this happened to any of you or is it just me?

Specs:
G930F model, Hungary, Telenor (Unlocked)
Android 7.0 (updated about a week ago, had no such problem before today)

Oh and also I forgot to mention that when I turned off WiFi on my S7 I had internet connection on all my other devices. It wasn't showing any signs of WiFi usage, there were no updates going on in the background.

 

[Hey I Tried]

Well, first thing to do would be reboot your router.
Next, they going into your WiFi and forgetting any networks that you have saved, then reconnect to your WiFi again.

Any programs that you may have installed in the past few days might want to be removed one by one, to see if one of them are causing the issues.

If that doesn't help correct the issues, you might be stuck Factory resetting the S7.

I know that there are s7 users out there that have WiFi disconnection issues.

Now the Wifi issues are gone, but still reboots every time I want to quit the YouTube app.
