S7 Frezzes and black screens

Hey everyone,

I have the problem, that my S7 frezzes in irregular situations and then there is no interaction possible. The display is always black and just the Softkeys and the LED is pulsation.
To solve this issue I try to reboot my phone with combination of the Vol- + Power and Home Button. Sometimes I get into the Download Mode, and reboot the phone from there.

After the reboot of my phone the black screen is away and my device is working well again. But after a few minutes is it not possible to activate or deactivate the WLAN. Therefore I reboot my phone again. When I am rebooting now the phone I noticed that the phone does not shut down correctly. After a short vibration the softkeys are active again and the blue LED is plusating. To solve this issue I try to reboot the phone again with the combination of Vol- + Power and Home Button. Moreover I noticed in the settings that my device shows instead of "offical" the word "custom" in those situations.
MY DEVICE IS NOT ROOTED OR HAS OTHER MODIFIKATIONS!

After deleting the cache partition in the stock-recovery the device is rebooting again and everything works fine. The settings shows now the status "official" again.

My phone is always on the newest firmeware and patches:
Model: SM-G930F
Android-Version: 6.0.1
Basebandversion: G930FXXU1APEQ
Kernelversion: 3.18.14-8206888
Buildnumber: MMB29K.G930FXXU1APGG
Android-Patches: 1. July 2016

PhoneInfo says:
CSC-Code: VIA (O2)
Bootloader-Version: G930FXXU1APGG
PDA-Version: G930FXXU1APGG
CSC-Version: G930FTEF1APG1
Basebandversion: G930FXXU1APEQ

I think the reason for my black screens and frezzes is a corruptive firmware and it is not fixed yet from the Samsung updates.
I exclude a defective hardware for the reason that the device works normally after the restart and if the display would be really broken anything would not work.

Do you think I could be apps that let my S7 crashes so much? I have installed Spotify, Facebook, WhatsApp, Snapchat, Instagram, GearVR, Twitter, YouTube, Google Apps and LinkedIn.

I am thinking about installing a Custom ROM to eliminate the problems. Can someone who also had a Black Screen confirm, whether the problems are away with a custom ROM?

Thank you very much for helpful responses!
