[PROBLEM] cant use front camera.... on stock! - Xiaomi Mi A1 Questions & Answers

hi all!
i'm having problem with my mi a1 front camera
the button for camera switch simply disappeared
already tried factory reset a stock flash with "mi a1 tool"
watsapp and messenger cant use the camera either
tried also some other camera apps from play store and this is the result : "the camera device is currently in the error state; no further calls to it will succeed. there is a problem with camera service, if persist please restart your device."
i'm on stock firmware and recovery, my mi a1 is "untouched"
what can i do?
thank you very much.

I have problem with telephoto lens, it switches automatically, but if I switch manually to telephoto, the app crashes, same thing goes for gcam...

[Q] Camera 360 issue

Hi!
I've got a problem with an app Camera 360 Ultimate. After installing everything works OK including front camera, but when i want to switch to the back camera then there is an issue: "Camera won't start. Please retry later or restart your cell phone". Of course i tried restarting (rebooting) but nothing happened. Does anybody know how to solve this problem ? My device: Galaxy S4 i9505 on Cyanogenmod 12.
Thanks in advance

'Rear Camera' and 'Flash light' Not Working in Lenovo k6 Note

I am not able to use Rear Camera and Flash Light in My Lenovo K6 Note. Front Camera Works Well.
When I open Camera App, by default it Opens with Front Camera. Rear Camera Option is Not Found. (Front Camera works Perfectly Fine)
Even when i opened WhatsApp and Take a pic, only front camera is shown. No Button to switch To Rear Camera. (Front Camera works Perfectly Fine)
When i swipe Down the status Bar and try to switch on 'Flash Torch light'. it is not working.
(In Stock Rom Front and Rear Camera Works Fine even Flash Light Works Fine.)

You installed Rpm for karate which is lenovo K6 Power. You need to install ROM for karatep which is K6 note ! So full wipe in TWRP and install Karatep version of the ROM, this should help.
