Lol, does it affect picture quality ?

Yes, a lot of these units are in the market. Face ID fail I will think more parts are not original d , replaced before hence faceid won’t work. I bought before once, got it , works okay, then I updated the OS from iOS 12 to 13 I think, voila my True Tone went missing . Googled up only I found that it usually is because the screen was replaced with an after market one.

So really be careful when it’s really too good to be true. Best is used Malaysia sets I feel and from direct owner.. not shopeee kind .. just my opinion.
