Yesterday I have installed LineageOS 15.1 on my FP2. I runs almost fine, but trying to play a song on a music player sometimes, but not always, causes a total system crash. The syxtem frozes and after a while it reboots by itself.
I have installed Vanilla music player via F-Droid. Maybe it conflicts with the preinstalled music player. I could not figure it out clearly yet. No matter on which of both players I try to play a song, both can cause a system crash. Now I have disabled the preinstalled player and rebooted the phone. The first time I tried to play a song with Vanilla, the system crashed again. But after that Vanilla is running well, yet.
Can someone confirm this behaviour? Is it based on a fixable issue?
Before Lineage I had Fairphone Open OS installed for eight month. It ran perfectly stable in all cases. But I wanted to use an open OS, that is based on a newer Android version and that will be updated und upgraded for a long time. But unfortunately, Lineage seems not to be that stable.
In rare cases I get a freeze like this with the stock music player in connection with Bluetooth playback. A simple reboot always fixed this so far.
Music is playing fine without a Bluetooth connection for me, so I blame it on Bluetooth being the mess it is.
I’ve used LineageOS on the Fairphone 2 since 14.1 and can’t complain at all about the stability of it.
As LineageOS 15.1’s days on the Fairphone 2 seem numbered already, perhaps you want to try whether the problem persists in the upcoming LineageOS 16.0 based on Android 9 …
I did not try anything to fix this issue yet. I think, it’s a kernel bug that only matters in special cases. But meanwhile it seems I get rid of it. I have played songs with Vanilla in the last hours sporadically without any problems.
But to me it’s still frightening, that an app can just crash the entire system.
