Whenever I make, receive or even check my balance(which had absolutely nothing to do with the sensor), after the call is over proximity sensor still works!
Gets pretty annoying some time Later, can't work, play games, watch movies just somehow hand comes in front of it and then Sensor detects it and black out the entire screen!
Please if someone knows anything about it, I desperately need their help! Thanks.

Might sound silly, but have you enabled all your Samsung Air/Gesture commands etc? -- also Smart stay/Pause?

If so, disable them.

I absolutely never enable them they're off since I got my phone but the sensor still continues to annoy me!
What should I do to stop it?

there are a few thread for proximity sensors problems... search and you will find some useful information.
but in short, there is probably some dust in front of the proximity sensor.

a temporary fix is to blow some air in the earpiece... but the problem will eventually come back.
I do this once a month.

The other thing you can do is disassemble your phone, clean the proximity sensor lens, maybe add some kind of protection to protect it from dust... and reassemble everything.

But how to disassemble the phone it must be a risky business!

Try going to Settings>General>Application manager>All>Phone and clearing data.
If that doesn't help, try doing a factory reset.
Failing that, try availing warranty, or if you are Knox 0x1, try another ROM.

His problem seems to be a software issue and not a hardware one.

I had the exact same problem with my device... and the problem is hardware (dust in front of the proximity sensor)...
I tried everything, including a factory reset, and the only thing that fix it (for now) is to blow some air in the earpiece.
Next step will be to disassemble and clean the sensor manually

But I can't send my phone to Samsung because I rooted it and that triggered Knox warranty so I probably need some other way!
If anybody knows anything please help!
