When I call with the smartphone (HTC one M7) I often click the screen with the cheek.

I have notice that on Samsung Galaxy tab 8.0 when I call is there an option that disable the touch. Is it possible to import/install this feature also on HTC One?

  • Is your M7 rooted? If so, you might wish to check this post on XDA for a possible fix.

You're looking for "proximity sensor" settings. If your proximity sensor is enabled and your screen doesn't go black when the phone is to your ear, the sensor (looks like a tiny camera lens, usually in the upper screen frame) may be covered by a screen protector or case, or may have failed. If you can't find proximity sensor settings, your provider's tech support should be able to help.


I had this problem, used the #0# thing to test the proximity sensor, it seemed to be fine (screen went green whenever my hand got close to the screen). Went to phone -> setting -> call and disabled the "turn off screen during calls" thing, power off, removed the battery, blew into every hole I could find, reinstalled the battery, powered on, went back and re-enabled the "turn off screen during calls" thing and now it works. Go figure.
