Portrait Camers Stuck at 1x in 12promax - Measure APP not working

Hi,

if anybody is facing this problem, please note, it's a software bug, I was about to change the entire camera module and luckily my local repair guy does it for free! I don't know what he did, but the problem is gone. I tried every resetting and formatting option as given in some Apple forums! none of them worked. The easier solution provided by all community members were- contact support! which I didn't want to do because I was out of warranty
