I was having performance issues with Spotify on Android, temporary lock ups, crashes, etc. This is on Android 5.0.1 (Marshmallow) on a Huawei Honor 7.
It seems to be due to the fact that my cache is on a Micro SD card… and I’d bought a “standard” (ie – slow) Kingston one. Copying my card to a new fast one (Samsung EVO+) and swapping them over *seems* to have fixed the issue.
Update: didn’t fix it, disabling nuplayer fixes it!
