Why do I think this?

A Facebook app (with no name below it, and a darker blue, also wouldn't open) appeared next to my originally downloaded Facebook app.
-I have unlocked my phone while using a charger. I live with 3 roomates, and we don't get along to well.

I've searched and searched and came up with nothing.

Try turning it off then back on

I would say you just have to reset it to factory settings

You have been infected, that is for sure. If you plug your phone into a Mac, it should show the screen of your phone in the Mac screen. You can try wiping your iPhone, them resetting it. If you don't want to loose all your data, save everything onto any PC. Wipe your iPhone, then restart it. Download your files, and the virus should be gone!

Make an iCloud backup ONLY ICLOUD, reset to factory defaults, and then restore from iCloud. iCloud backups only store a list of apps from the app store you had (not the actual apps. That would take up too much space) and their save data. If you still experience wacky behavior your best bet is to reset completely. I hope this helps!

Well yeah if you use a magical fake charger thats been rigged that way. lol

In that case just restore to factory and use a regular charger after that, problem solved.
