On my old phone I had an issue with the proximity sensor and front facing camera. This led me to holding my phone backwards to take photos and being unable to hang up phone calls.
I think I put up with this for a year and a half.
I did end up figuring out the issue with the proximity sensor but opening up my phone to reconnect the camera module was too much effort for me.
My computer wasn’t booting properly for a month or two, I think it was saying boot drive not found or something. It would work if I went into boot options and picked my main drive.
The cause? I used the Blu Ray drive for the first time in years, and for some dumb reason, that was listed higher in the boot options. My computer was trying to boot into a Blu Ray of Blade Runner
