Cannot unlock screen if already locked when answering incoming call

[robrandon]

REALLY frustrating problem!:

Using a Galaxy S4 with Android 4.3. I use the swipe feature to unlock the phone.

If the phone is unlocked when I answer an incoming call, I can use all of the phones features, including Mute, Speakerphone, etc.

However, if the phone is LOCKED when I answer an incoming call, I cannot unlock the phone. Pressing the main button does not bring up the screen to enter my password. It just stays blank. Therefore no Mute, no Speakerphone, no access to contacts, etc. By default, you can't even end a call! If someone called me and just put me on hold, I would have to pull the battery to hang up. Fortunately I have set the power button to hang up calls, but that doesn't really fix the overall problem.

So, how do I get the phone to at least let me unlock it when in this situation.

Thanks.

This was fixed in update 4.4.2.
