Apps keep stop working

[Taari12]

Whenever i download something on my s21 ultra every app stops working and i have to restart my phone. Any solution except factory reset?

Eg- co.g.app stop working etc

This isn't normally an issue with Samsung Devices. 

What is the model number of your device & what country / region are you in? 

Go to Settings > Apps & Toggle On "Show System Apps" (Middle Right 3 dot menu) > Toggle Show System Apps & Click "OK" and Search for "co.g.apps" Scroll down to Storage & Clear BOTH Cache & Data for "co.g.apps".

NEXT & STILL in Settings / Apps & Search for Google Play Services & Scroll down to Storage & Clear BOTH Cache & Data for Play Services.

NEXT Still in Settings / Apps & Search for Google Play Store & Scroll down to Storage & Clear BOTH Cache & Data for the Play Store & Reboot.

Did all these steps. Still it keeps happening

If you did everything, then as much as you might not want to, Factory Reset may be your only option.

I have 400gb of data with images and app data and opened tabs in Chrome. Whats the best way to backup and restore this much data?

[RedDogRabbit]

I'd copy the important data to my computer & other external storage. 

You must have 1 TB storage on your device?

Smart Switch backup to your computer & OTG Storage is what I would use.
