proximity sensor issue on Xperia C

[Ptandon]

screen would not dispay after call is dialled. Re installed phone software, tested it with sony diagnotics, worked in 1 out of 4 or 5 instances I ran the test.

Any solutions?

Is there anything near or on the proximity sensor? protective case, or protective film or even grim? 

You can test it

Yes this is done.. There is nothing around it.. I downloaded this app also called proximity sensor finder from Google Play Store. It also showed the same results. Once an object is passed in Front of the proximity sensor..it detects.. But when the object is removed it doesn't....

It might be a hardware issue. you could repair your phone with SUS or PCC but if that doesn't work then

You don't have to create multiple threads, one is more than enough

Looks like a hardware issue to me as well. I had taken it to the service center who formats, reinstalls the os & gives it back. Works for  few calls & then is back to normal. The company is not yet ready to accept the issue as a hardware one.

Only option I see today is to use a flipcase all the time & making sure that not even a fingerprint comes nearr the sensor. This is an un relasitic solution for a phone in this premium segment.

Dear All,

I don't know whether this solved the problem or not, But even I am facing the same problem. I bought the phone last week and also put a scratch a guard on it.

When I am dialing a phone and put it on MY ear display automatically turns off but when I want to end the call it never turns on nor power button works.

Kindly advise whether I should remove this scratch guard to fix this issue or not or is their any other solution for this. I am having 30 days replacement gurantee with the online portal from where I bought this.

Thanks In Advance.
