So then I tried flashing 19.5.3 again using sbf+rsdlite. After that did a factory reset. The magically the front camera option was back
however when i tried to use the screen would show a purple distortion, the image would freeze and then you'd have to press back or home to get it back out.
I figured it's a hardware issue, so i got a camera replacement from ebay. After I had professionals install that, it reverted back to the state when the front camera option just isn't there anymore
I've retried flashing the firmware, flashed 19.6.3, flashed 19.5.3 and then took ota to 19.6.3...but nothing works. Please help me out someone!
