Background app issue

Seeing how google play services is deeply integrated in phone system it might be tricky buuut....if you wanna (on your own risk) you can get debloater from github. Run it on your computer and connect your phone. Choose what apps you wanna remove. Or you check security-privacy permission manager and see if you can't fix it.

Samsung Knox can unfortunately block the process of github. He/she can try to force stop playstore then deactivate it and activate it again. Or do a factory reset it solves a lot of issues. /AndroidSweden

Hi @RawDng 
Sometimes "Force Stop" fails because the system auto-restarts the bugged process. To truly break the cycle:

Clear Data: Go to Settings > Apps > Google Play Store > Storage. Tap Clear Cache and Clear Data. (This resets the store, not your apps).

While you're fixing this, keep your phone out of its case and avoid charging it until the temperature drops. 

Restart the phone immediately after clearing the data to kill any remaining "corrupted" processes.

If that worked out, it's also recommended to change the Location permission to "Allow only while using the app".
