Hi, I have received Xiaomi Redmi Note 4x phone with band 20 included. It came with global version 8.1.14. The front camera was working at this time because I took photos. After update to Global 126.96.36.199 the front camera stopped working. Now I've flashed other older global version and also flashed dev version and the front camera still dont work. The switch icon on the camera simply dissapeared and even in Whatsapp and Messenger dont work in video calls. Only the rear camera works. I did the hardware test (CIT) and I got the result "Front Camera: Not supported". I've already cleaned all caches, did factory resets, flash other Roms, tried different cameras applications from play store and I dont know what else to do. Any idea how fix this? Check attachments for photos. Thank you.
