On 12.11 it seems that my phone will randomly freeze/hang and nothing short of taking the battery out can fix it. I have tried fix permissions, checking apps, disabling setcpu and others to no avail. It seems random and in no way affected by apps or anything I am doing on the phone. I also find that there is sometimes odd behaviour with MIUI music from the lock screen such as pressing play may start a song then skip a few right when it starts playing. Any ideas? I'm betting a fresh 12.17 will fix all this. All comments appreciated.
