Xperia M dual reboots itself when WCDMA is activate

[Jerry17]

Hello,

my mobile reboots after some minutes if a have activated the WCDMA mode (WCDMA only or WCDMA/GSM). At GSM only it is stable.

I have two SIM cards inside (AON and Drei). I changed the SIM cards (got new ones) and tried with different  provider too. But always the same

I had the mobile for service at Saturn (where i bought it) for 3 times about this problem. They alway updated to the newest software (so they told) and after the 3rd time they changes the board inside.

I have the same Problem and before it heats up to 60°C. So i think the phone shuts down, when it is getting too hot, but why it does going sooo hot when i use the WCDMA mode? 

Ive already conntact the support and hope it will be repair by gurantee...
