X526 front camera is not always working

[AdrianTry]

Hey there, I got this weird issue regarding x526 front camera as it's not always working. After pressing button to switch to the front camera the camera app will freeze for some time and then will display info "cannot connect to the camera". The only way to fix it is to clean dalvik / cache, but its only temporary solution.

I have tried various ROMs from 6.0 to 9.0 and different camera apps, but in all these ROMs either front camera won't work from the start or will stop working after brief usage.

Any ideas how to fix this issue? Any help will be appreciated.

Dirt in front camera

A little update to my first post. I have noticed A lot of dust in the front camera lenses. It looks like someone was trying (unsuccessfully) to fix that camera, probably from the store. I have bought this phone from Bangood. Was anyone of you in a similar position as me? I contacted Bangood and told them I want them to resend a fully working phone. Still waiting for their reply.
