I've faced a problem using RingtonePreference in my application. An attempt to show RingtonePreference dialog cause an app crash with java.lang.IllegalStateException. Some logs here:

The most weird detail of this problem that it's not common. This bug can be reproduced only on the specific devices (crashes on Moto G4 API 23, Moto E4 API 25, Lenovo K8 Note API 25). It seems like a platform issue, but is it?
