Uninstall App that appears after a call

I bought my Samsung Galaxy a5 2016 just 2 days ago. I must have installed something by mistake and I can't uninstall it as I don't know which app to remove. Each time I finish a call, I get a new screen that I can choose if I want to call or text the number I was just calling. I have a screenshot if it would be helpful. Although I don't know how to attach it here.... Please help me !!!!

Note 5 appears to be charging when it's not

Hello everyone, I seem to have a problem with my phone, This has been happening since last night. The day I woke up, everything was perfect, then around mid-day, I charge my Note 5 through my computer, then every 1-2 seconds my computer starts playing the disconnected/reconnected sound, and on the other side, the Note 5 flashes on showing that it's charging with a vibration. So I remove the charger, and then the phone continues to flash on with a vibration and saying that it's charging repeatedly, even when the nothing is connected. It also shows the neat little charging animation on the bottom of the screen when you charge it. So in conclusion, when charging, it rapidly disconnects/reconnects flashing the lock screen, with a vibration and charging animation, however upon removing charger, effects still apply. (Appears to be charging when nothing is plugged in. Any tips or advice will help. Thanks.

*Side question: my Note 5 is still in the Lolipop update, and when I go to software updates in settings to check for any updates, It doesn't find any. My Note is a Verizon. Is there any other way to update it? Thanks again.

My MicroSDXC Card Appears to be Incompatible with the Samsung Note 4

I bought a used Note 4 to replace my aging Galaxy S4. I have a 128GB PNY MicroSDXC I used with my S4 and I had no issues. My mother has a Note 4 as well, but it was purchased brand new. Both my used Note 4 and my mother's Note 4 does not recognize the 128GB PNY MicroSDXC card, but my computer and my old S4 recognizes the PNY card perfectly fine.

Is there something incompatible about the PNY microSD cards? I searched online and I cannot find anything on this issue.

This problem is a beyond me because I thought SD cards were universal.
