Hi, all. I'm experiencing some sudden, difficult-to-explain random reboots. I've had the phone for two days. I haven't had any problems until today. The one thing I did differently today was turn on the phone after I plugged it in. Other than that, nothing different. Taking out the SIM stopped the reboots, but I kinda need it
I turned the phone off the proper way and turned it back on. I then plugged it in and there were no reboots. I unplugged it and they started again. This SIM works fine in my other phone. Also, the reboots only occur when the phone is idle, probably within five minutes of my last interaction with it. If I keep using it, no reboots.
Normally, I do my own problem-solving, but it's a new phone for me (I have no background with it) and I can't really wrap my head around this. It worked fine for two days and I used it for awhile yesterday after installing a few new apps. I really don't think it's an app. Any ideas?
