I have a problem on last stock firmware 1.0.5. I use my player in Android mode with Tidal (it is the only one additional app installed). When it plays music all works fine. But when i pause or kill application my player turns of in 30min or 1 hour (can't say exactly). When it turns of it even doesn't charge. I have to long press power button 2-3 times to turn it on, then it starts boot with dx200 logo. I checked all turn off timers in Mango. Tried to factory reset device, all the same. May be it hardware problem?
Are you on the latest Tidal version and does this happen in the Mango OS?
