Hi guys,

Tried :

I'm currently using stock ROM

Thank you,

Have you run the built in tests;

Try running CIT Mode and run test on all cameras...

To enter CIT Mode Dial *#*#6484#*#*

Check if all cameras are working on CIT Mode

What's your plan after your phone being unlocked?

same problem, since the update to android 10 (at the moment a MIUI global 12.0.1) ==> cant use portrait mode : "cant connect t ocamera" . then i get freezes.
CIT teset says, that rear sub camera fails.

I dont think i broke the cam. it seems to be related to the miui 12 update ( android 10).

I dont know how to solve this, and its pretty annoying

Nope still not working after reflashing via fastboot latest ROM

What's your plan after your phone being unlocked?

Tried using MIflash Fastboot ROM begonia_global_images_V12.0.3.0.QGGMIXM_20200902.0000.00_10.0_global.tgz ,
Still no luck,

"Camera error"
Can't connect to camera

I'm not sure what's the ROM version fix for this one

I tried this and turns out the cameras are not working - master, twin and vice back camera, all are crashing

 

[Nerfpl]

Today my camera app broke.
It says "can't connect to camera", "waiting for camera" or stays at black screen.
I tried wiping data/cache.
I did test using hidden menu and all cameras are working.
Other cam apps are working but I prefer stock one.

Phone is Xiaomi mi 9 lite with lastest update MIUI 12.5

Please help. Thanks.
