Light sensor not working after lollipop update

[daltzi]

I run the diagnostic test on my device after the update and light sensor failed.it worked normally with kit Kat 4.4.4! Another bug? Can anyone help?

I have no problem with my sensors. 

Do you see the same problem in service menu?

Dial: *#*#7378423#*#* goto: service tests > Ambient Light Sensor

If so, I suggest soft reset (hold volume up + power key a few seconds)

Nope.. working fine in service menu!!

Then the issue is probably within the diagnostic app itself.

Same here, light sensor not working after update. Screen not turning off on calls. CPU-Z shows 5-25 lux.

I agree with @darp   I haven't been able to recreate your issue, it could be that an app it's creating this issue, @SomeQuickAdvice boot on safe mode and run diagnostics again or repair your phone with PCC
