[Q] Has anyone had a Lumia 710 that randomly reboots?

[phantomsniper773]

Hey guys, so I recently got a replacement Lumia 710 from the Nokia repair center, and it works fine but I noticed that it will reboot completely randomly around 2-3 times a day. From what I can tell, there is no specific trigger that causes this. It's almost always been idle (sitting on my desk/ in my pocket) except for a couple times. This problem occurs with stock and custom ROMs. Also when the phone comes back, it seems like the battery percent jumps down ~4-6%

The only thing I can think might cause this is a new SIM card. Before I sent my phone in for repair, I had a regular SIM that I cut into a microSIM. Almost immediately after getting my replacement phone, I activated a real microSIM I got from AT&T. This weekend I plan on trying to get a replacement SIM card from AT&T again to see if that fixes it, but I wanted to know if anyone else ran into a similar problem.

The thing that really confuses me is how random the bug is. It happens whether the phone is in use or not, at random times of the day, on a couple different ROMs (including stock), and only 2-3 times a day. I'm considering sending it back for repair, but I'd like to hear from you guys before I go 2 weeks without a phone.

Phone Info:
T-Mobile US RM-809 Lumia 710 (white)
Phone OS: Currently running WP7.8 (RainbowMod ROM) but the problem is ROM-independent.

Hi,

exactly the same problem but only since the 7.8 update. Before the update my wife never had any random reboot.
The phone reboots randomly 2-3 times a day.
Maybe it's a coincidence.
