I'm using a Samsung Galaxy S4 I9505G (google edition) with Android Kitkat 4.4.

Since I updated to Kitkat, a weird bug has propped up. When I'm on a call and wish to put the call on speakerphone, I am unable to turn the screen on by using the power button. I keep pressing the power button like a maniac and after about 20 presses, the screen might come ON.

This issue happens almost exclusively when I'm on a call, otherwise the power button turns on the screen just fine.

Anyone facing a similar issue?
