Phone UI Always Crashes in the Same Store [Update]
I visit a store regularly and every time to try to reference something on my phone in that store, I get UI crashes. The phone works fine everywhere else. Its a Oneplus9 running a custom rom. Two questions: 1. What could cause this? Is some sort of interference in the store crashing things? Is the br...
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?
You're viewing a single thread.
Log seems to indicate issues with scanning, which could be maybe too many APs around. I believe I may have experienced something similar in a mall briefly.
Does turning off WiFi help? Like full on airplane mode, and make sure to disable WiFi scanning when WiFi is off as that remains on by default for location services, you want to kill WiFi scanning completely.
Yes, I forgot to mention in the post, but turning WiFi works, only if I also turn off "detect high quality networks" and "turn WiFi back on when high quality network is detected" or whatever those options are.
Hmmm, that's a theory. I'll see what I can do to find all the APs and figure out if the WiFi chip in my phone has a known limit. I don't think I have enough old routers to crash it myself. :-D
