yes. I think it's a software problem. I replaced one because of it and still have the same problem. Waiting for htc to update it. Think it's a known issue. Do a search for data problems or something like that, many have it.
This could be a setting in your profile causing the issue. If you go to community.sprint.com forum you may be able to get the fix from the online sprint tech. Go to the link below. Good luck..
