Question About Making Calls.....

[gpkid16]

Hello everyone, I am new to the Q and this forum! I just got the phone activated today so I still have a lot to learn. So far, I have had 2 issues with the phone that confused me. I was on the phone earlier today and I hung up with the person I was talking to, but a few minutes later I looked at my phone and it was still counting upwards. I had to turn the phone off to make it go away. The second issue happened tonight when I was on the phone for about 30 minutes. My screen was black and I went to turn the volume up and the screen remained blank. I am getting kind of nervous that I have had 2 issues in one day, but maybe they are simple settings I do not know about. Thanks!

did u press the red button on the upper right corner to hang up? did u try pushing and holding the thumbwheel to adjust the volume?

I tried hitting any button and none of them worked. The screen remained blank.
