Among other things like apps closing on their own, keyboard won't pop up when I try to type. I'm not getting my texts. Any suggestions?
Have you tried texting your phone to be sure? Because it can also be because of network issues.
Hmm.. If I'm experiencing too much problem on my phone, what I do is backup my files and restore it to factory settings. I would recommend that for you too, just don't forget to backup your files.
