Usually on Android, there is a button to show what apps are running the background - this isn't a list of system processes (nor system apps), but user started applications (games). After we press the button to see the list of apps, there is often a button which closes all open apps. This should be familiar to everyone who uses Android!
The problem I have is, my daughter's Hawaei MediaPad running Android Version 8.0.0 doesn't persist the close. When we press the square button, we can see all running apps. If we close each individually or one at a time, return to the home page and then press the square button again, all the apps remain.
I tried with an app called Advanced Task Killer from the Play Store. By clicking boost (which means close apps), a progress bar was displayed showing it was killing each task, but again as soon as I open the list of running apps, instead of seeing an empty list which is what I expected, I see the same list of applications.
The only thing that kills the list is a restart of the machine.
Is there anything we're doing wrong?
I've played with this tablet a little more. Some times when I choose to kill all, they all disappear. If I return to the list, it remains empty (great). if I start another app and return to the list, instead of having only that recent app, it is listing all of them!
When I kill the apps, it sometimes shows a message showing how much memory I've freed up.
I also should point out, this machine is my daughters and as such has Family Link. I'm not sure if that has made any impact.
