The ranking may make it sound like samsung is the worst. But that’s not been the case since android 12. I do not have app reload or app killing issues on this one and find it much better than what I used to experience on miui.
I published an app on the play store that purely relies on a persistent notification + wakelocks to keep the screen active (since the whole point of the app is to keep the screen awake) - Samsung was definitely the worst when it comes to this for my app, as I would receive endless support emails about people with Samsung devices where it would get killed, even when disabling battery optimization for my app. The other manufacturers listed there came up every now and then, but disabling battery optimization generally did the trick for them.
With there being nothing that I could do for my app, I tried disabling compatibility in the play store for a ton of Samsung models, but then I got even more emails about people wondering why it wasn’t available anymore so I re-enabled it, but to this day there’s still (AFAIK) zero things I can do to prevent the app from getting killed on those devices.
What app is that? I only notice app reload issues when I max my ram usage playing heavy games or running apps that require maximum ram.
