Today I finally picked up my phone from in-warranty repair (motherboard replacement), I found out the camera doesn't work (it did before).

Same thing in CIT test menu:

I mean, this one is on me. I bought Poco X3 Pro knowing damn well it's plagued with issues. But €188 for phone with Snapdragon 860, 120Hz screen, big battery, stereo speakers, headphone jack and IR blaster 1 and a half years ago? Hell, that sounds too good.

And yes, before you ask, I have tried turning it off an on. Also resetting both from settings and recovery.
