To ensure proper background running please:

Check that access to “Do Not Disturb” mode is allowed

Go to Permissions – check that all permissions are given

Go to battery – manage battery usage – set DO NOT OPTIMIZE

Go to data usage – set unrestricted data usage

Additional “risk factors” – third party apps.

  • Apps that claim to Save Ram
  • Battery-Saving Apps
  • Data Savers
  • Phone Cleaners
  • Antivirus Apps

The idea behind all these apps that claim to boost your memory/ battery etc is to systematically close apps running in background.
