Hi folks,

About a month ago, I posted the thread at the shared link because my phone keeps spontaneously rebooting at my local Safeway store. I found several other people with similar issues online, but no one who has discovered the actual cause. I also haven't fully understood why, but I have a few updates to share since visiting the store a few more times.

• Scanned subGhz (w/ flipperzero) and Bluetooth frequencies. Lots of interesting things. Something bluetooth or bluetooth LE keeps popping up on the logs on my phone before the phone crashes, probably a beacon
• Turning off Bluetooth does not stop the behavior
• Pulled the log from the phone post-crash and it has some interesting things in it. I don't understand it fully, but it reads like the whole system is dying due to something happening in the wifi manager?

Can anyone glean any additional information from this:

I think what's happening is the phone is trying to take some kind of action based on a beacon and is crashing, but I don't have any loyalty apps installed. Does anyone have a better understanding of how this stuff works?
