Since returning from holiday I have multiple issues with my phone. I often get error messages like "com.android.phone process has stopped working" or "com.android.media has stopped working". The battery life has become awful (from over a day with normal usage, to around 6 hours normal usage). If I do a reinstall of any chosen ROM its fine (with the data and cache wiped). When I then do a titanium backup restore all the problems return. Any idea what setting would be causing this issue? Whilst I was abroad I was connected to the local croatian t mobile network and had data turned off. I didn't connect to any wifi hotspots out there.
