Should I reset my iPhone?

I just got my iPhone 7 Plus with 256 around 3 weeks ago. Everything was fine and it let me download apps easily. Now, whenever I try to download an app it takes forever to load and then it asks me for my fingerprint and then has me put in my App Store password like four times before it actually downloads. Also, whenever I open a game some weird Game Center name comes up and when I click on it it doesn't let me go to the Game Center. Should I just reset it?

Shouldn't hurt to try at this point.

  • Will the MAC address of my iPhone reset if I reset my iPhone to its factory settings over iTunes? I have jailbroken my device and used terminal to change my MAC address so that I could connect to school's Wi-Fi. But when I wanted to change it to its initial number, I typed in a wrong value and it just messed up my Wi-Fi, I can't connect to Wi-Fi anymore. Wonder if resetting to factory settings would help…
