Phone eventually got hot and I can't wake it up. Note it was useful earlier, but seems to have locked up just after I installed an app via pkcon.

[Victor Thompson (vthompson)]

Does this only happen when you open an MP3 with the app? Or is it consistent?

[Alan Pope 🍺🐧🐱 🦄 (popey)]

Finding it hard to reproduce. It only seemed to manifest itself after some hours of the music app being completely idle. Will try though.

[Andrew Hayzen (ahayzen)]

Is this still occurring? Also could this be linked to bug 1289804?
