Went into application manager, but wasn't able to identify the culprit, and to my annoyance I wasn't even able to stop it at all (except for by reboot)! Battery stats showed a lot of drain by media server, but it wasn't in the process list. A friend suspected Timely to be the cause of it, but uninstalling that alarm and clock app didn't stop the melody. After another reboot the tablet remained silent - until a minute ago, when I plugged the power plug into its jack. [emoji35]
Anybody here having a hint for me? I'd really appreciate!
