Why does my phone hang up when I answer it?

[Android Central Question]

I hear a bit of the phone call, enough to determine who it is, but nothing more, and the call is ended automatically by the phone. Makes me seem like a terribly rude person. How do I stop my phone from doing this?

Welcome to Android Central! Which phone, and which carrier? Is your cell signal strong or weak when this happens?

 

[triplettmelissa]

It's a Samsung S6. Carrier is Sprint.

And how's the cell signal when this happens? Does it also happen if you make the call, or only when someone calls you?

 

[triplettmelissa]

The cell signal is fine. It only happens with calls I answer. I can make an outgoing call with no difficulty.
When there's no internet/cell signal it won't even ring and goes immediately to voicemail.

Is the screen staying on when you answer the phone and put it against your ear?

 

[triplettmelissa]

I don't put it to my ear. I answer then put on speaker phone to hear because I have a hearing problem. The screen stays active, but switches to a call ended report screen before I have a chance to do anything.

What phone do you have? Are you using a screen protector? Is it possible that the screen protector is blocking the proximity sensor?

The OP mentioned having a Galaxy S6 on Sprint. A screen protector blocking the proximity sensor could explain the screen going black as soon as a call is made, but it shouldn't cause the call to be disconnected.

Any possible reason or setting for the disconnect we haven't yet ruled out?? However absurd...
