If I text someone and then just hit the home button it doesn't notify me when they text me. The AT&T messaging app does this too and is otherwise fine but that is the main reason I switched to this one. I figured it was a bug but yours does it too. It's a deal breaker for me. If someone thinks this is a good idea still then maybe just have an option to have it notify of all texts to override this bad idea. It might have cost me thousands because I missed 2 customers texting me this month who moved on to another realtor after I didn't reply!! It would have been nice to know they texted me back to begin with.
