I want to completely reset my smartphone, and just fiddle around with Android in general. It's becoming slow, especially connected to internet, and there are a lot of folders on the microSD I don't even know where they originated from. All I want to save is my contact numbers and my text messages, all the other stuff can go. So 2 questions; How can I keep my contact/text messages, even through a reset? Which Android OS would you guys suggest? I came up with this list via Google, but I want to hear your suggestions of course Also, I'm pretty sure I rooted my phone a few years ago, so no worries there.
