proximity sensor issue

[spiralz]

My phones screen won't come back on after making a call seems to be a proximity sensor fault.

As soon as I press the call button the screen goes blank even if it's not against my ear. If I press the power button it will come back on and then stay on even if I then press it to my ear.

Very annoying to be honest and I can't find a setting for it

Thanks

Do you have a protective case or anything covering the proximity sensor?

No the phone is completely naked

Seems to have done the trick thanks. I ran the proximity test and it showed it as working. So I restarted the phone and now the problem has disappeared. Thanks very much for your help

I have this very same issue, not a major deal but annoying, I have run the proximity test which didn't pass.. Does the phone need replacing or is there something i can do.

Regarding the proximity sensor:

If you close the flap at any time, the screen should go off, atleast till the flap is closed, and then come back on if it is opened. If not opened within you set sleep time, then it should sleep. However, this is not what happens on the xperia, which is quite strange in this advanced smartphone world. S4 does exactly what i'm talking about.

I haven't checked this on the S4, are you saying that the S4 has a sensor per flap?
