So, I just got the Moment yesterday and I'm having a problem with texts and vibrations. Yesterday I had it all working fine with vibrating when I got a text message, but today it stopped working. I went into messages and selected vibrate, so it should be working, but its not. So i looked around on the internet, and found someone suggesting the app "SMS popup". I got that and everything on it worked fine, EXCEPT making it vibrate. I have no idea why this is, because it was working fine yesterday. Is it a problem with my phone? An app I downloaded? Is this something I can fix or something I would need to bring to the Sprint store?
