I searched this topic and found that someone else had the same problem I am about to report but I am re-posting because nobody ever answered the first text message auto-delete post.
My droid will randomly AUTO DELETE all of my text messages in my inbox without any warning to me. It is very frustrating because I keep texts in my inbox that hold important information to me. This has happened to me about 4 or 5 times since I bought the phone 4 months ago. I checked the settings option to see if the auto delete was set, and auto deleta is NOT set. Why is this happening? And, more importantly, HOW do I fix this? It's frustrating.
thanks!
