Phone UI Always Crashes in the Same Store [Update]
(lemmy.world)
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?
it feels like that exception misses some context. I'm not familiar with kotlin, but it's java-like and this exception cause seems unusual, like if this text would only be part of an exception chain, and if we wouldn't see the inner (original) exception(s)
how did you obtain this?
When the UI crashes, it sometimes throws up a dialog with "copy URL to crash log". I just cut and pasted from there.
you may have more success with reading the systems logs, with the ADB tool and the
adb logcatcommand. it will probably have a lot of messages, you'll need to filter it mentally or in a text editor
