the carrier apps were uninstalled whein i bought the phone and are not critical to the use of the service.Yesterday the phone stayed open so I think that is a good step..
I will leave idle for a little more.The fact is though that I have removed the sim card and maybe it has to do with the network or sth that is not tested while the sim is off.
Other potential issues that might have caused:
a)The contacts I transfered from my htc desire hd in an sd card and I do not know how they were imported.
b)The spigen s view case might caused it to overheat
I cannot find anything else
