I have a samsung phone and it’s running android 11. The samsung keyboard app never stops running. I check it’s battery usage and if I have turned off my phone in multiple days it will show an app runtime of 70+ hours. In developer settings under running services it shows samsung keyboard 1 process and 1 service, the service being HoneyBoardService as input method and shows 20:02:29. Should it always being running even when the phone is not in use?
