Hey, I have recently switched from iphone to the s4. I got the s4 on friday and I have been having a problem with the default messaging app. It keeps crashing, it works for awhile then it wont load and I get the message that the messaging app wont load and I can either wait or close it. Closing it and opening it doesn't work, restarting the phone doesn't work. It just seems to come back on it's own. During the time it won't load I can't see or send texts, sometimes it will last 10 minutes or so. Has anyone else had this ? Anyone know how to fix it. Will I just have to backup and reset the phone ? Thanks for the help.
