I've had my DNA for about 5 months now and haven't had any issues until today. It's been EXTREMELY slow opening up SMS texts and sending them. I'm not getting a ridiculous amount of texts, and rarely use group chat. I cleared my inbox but was still unable to resolve the issue. I'm not getting a SIM card error, or an SMS error, it just takes about 30 seconds to open a single text. I don't have a problem receiving them, only opening them. I went through and closed running apps, I've hit the restart button and nothing happened, as well has powering the phone off, letting it sit, and powering it back on with no success. I use COMODO antivirus and have run several scans thinking maybe I picked up a bug but it did not come up with anything. I'm not watching porn or messing around with the operating system at all this just randomly developed last night and has continued through the day (so about 28 hours with this problem now). I'll probably end up going to Verizon store after I get off work tomorrow but if anyone has suggestions I'm willing to look into them as I'm not excited about replacing the whole phone. (This is actually my second DNA my first randomly turned off and wouldn't turn back on at all so I got a refurbished replacement phone) I treated both that one and this one very well, I do not drop them all the time from high places or anything crazy, the phone has an otterbox and a screen cover so there literally isn't a scratch on the phone. Please don't comment if you don't have useful ideas, a bunch of comments that just say "I'm having the same problem and don't know what to do" doesn't help me or anyone else that potentially has the same issue out. Thanks!
