I have a very strange problem with my phone
it does not work properly all the time, it reboots repeatedly

Works properly when: It is charging (ie battery connected and charger connected, and charging occuring) or when in flight mode

Reboots when: only battery connected, no charger and not in flight mode, ie connecting to network

this behaviour seems backwards from some google posts I read, ie reboots when charging. I see different errors, SIM failed, contacts not read, Message storage not ready. and when I run it apart and have some screws loostened its most often SIM errors. seems like it could be something as stupid as a connection or grounding.

very annoying why would it only work when charging??

thanks for all help, greatly appreciated
