Xperia Z1 keeps restarting randomly

Benzon — Wed, 04 Dec 2013 10:26:03 GMT

Hi all,

about 2 weeks ago I have bought Xperia Z1.

For first couple of days, I was using it only with wi-fi networks (mobile data connection sporadically), and everything was just fine.

But, few days ago, I started to use LTE and 3G mobile networks more often, and my problems really started.

The phone is keeping restarting randomly, but only when not connected to any wi-fi network.

When mobile data transfer is enabled, and the phone is using it, it restarts after soem time.

Today, for instance, I had a situation in which the phone was restarting over and over just after start.

The only way to settle this issue is to remove the SIM card, or use only wi-fi networks, but this is not convenient for me.

I tried factory settings restoring, phone repairing with PC Companion, nothing really helped.

Could anyone tell me, what can be the problem?

Try running the phone in safe mode for a while and check if you still experience this.

If you do I suggest that you contact your local support team to have this examined and fixed at a repair center.

I have already tried all of the hints found on this forum, nothing helped.

I have manually flashed the latest fw (14.1.G.2.572) - problem solved.
