because of this issue I removed Proctor glass too. but issue is same.
once it reset then issue will sort. but after few hours it happen again

I think the issue is coming probably due to some software issue because you said that the problem persists for some time if there was a hardware issue the outcome will be more worse than present

we don't know the exact location of sensors in a30 even we don't know whether a30 is equipped with proximity or ambient light sensor or not.
