Random apps appearing on IPhone 4?

I have noticed that random apps have been appearing on my phone lately. Not anything suspicious, but I definitely never downloaded them. Just today Iheart Radio just appeared on my phone. The other day it was KiK, I don't even have a KiK. My phone it always on my and locked so no one could be getting in and buying them.

Sometimes if you have an app it comes along with other stuff

Well first of all are you sharing an apple ID with someone? That's probably the reason why. There's a thing in setting to turn off so it won't automatically download it. I forgot where sorry

  • Why is my iphone not appearing in iTunes? The usb is plugged in and charging, so it means that its connected but when i open up itunes to sync some apps it doesn't show my iphone device anywhere. I looked under devices and it says none. I hate the new itunes update. Lol. Why isn't it showing?
  • What's with these random Apple ID password prompts when opening certain apps on iPhone X? Whenever I open an app I sometimes get a "sign into itunes store" prompt and have to enter my password. If I press cancel it closes the app. If I enter my password the app starts up like nothing ever happened. This happens at completely random intervals. I looked all over Google and only found a similar issue that wasn't quite mine. How do I make this annoying thing go away?
