I have the Ex 2 on T-Mobile prepaid. Lately, my phone has been doing weird things. For example, I keep getting unusual notifications in the notifications menu at the top of the home screen, like that I won a free app, or other suspicious things of that nature. Also, today, a bunch of icons appeared on my home screens that I didn't install. Things such as Priceline, Spy On Her, Zillow, Speed Boost, Partner Locator, App Store, Market, and Sexy Wallpapers. I didn't download or install any of these, but they just appeared out of nowhere. I'm a bit concerned. This actually happened once before, then I did a factory reset, and now it's happening again. Why would these events happen? Is my phone infected?
