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 bright light causing the luminosity sensor to overwhelm. Is the store trying to mess with or track my phone in some way and all my modifications, privacy configurations, etc. are choosing to crash instead of allow it?
  2. Do you have any ideas about how I can figure out what is causing it? Spectrum analysis with a flipper zero or something similar, logs of some kind on the phone, process of elimination? Links are appreciated if it requires advanced nerd cred (I’m probably intermediate with Linux, Android and tech in general, except networking where my knowledge is mediocre bit growing).

I am beyond curious what is going on because it is so weird that it works perfectly everywhere, but the UI keeps rebooting in this one store.

    Oh wow, me too! In my local grocery store I can only use my phone (particularly Todoist) about five seconds at a time before the UI crashes to the lock screen. I’m on a Pixel 5 with CalyxOS.

      I am running CrDroid Android 14 for a Oneplus 9. Just like the other link I found, mine happened at a Albertsons/Safeway grocery store. Someone posted something about Bluetooth beacons above. I’m going to pursue that as it sounds like a reasonable guess.
