My Go SMS Pro keeps crashing on me. It's either super laggy to the point where my whole phone freezes and i have to remove the battery to restart it or the programs takes a dive. I think part of the problem is me having way too many messages stored within the program. I have tried deleting them but my phone freezes when I try to do so. So my question is. Is there a manual way I can delete my messages besides using Go SMS Pro to do so? And is there any other way to fix my crashing problem?
