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:
- 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?
- 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.
You could try and get in one of those RF shielding cases and see if that helps.
They are usually sold because people are concerned about contactless somehow being used to steal their money, but since that doesn’t work unless you unlock your phone it’s a bit of an unfounded concern. The cases do actually block RF, so while they’re a kind of con, they do also work.
