The SMS keeps force closing on me on my Droid 41/09. Sometimes two or three times a day. When it force closes, it deletes all threads. It even does it when there is only one thread with a few messages in it. I haven't noticed anything specific that causes the force close to happen, it just happens when it wants to. I removed all downlaoded apps and the problem persists. I am using the default messaging app. Is anyone else experiencing this and has anyone found a solution? I absolutely love this phone and it is my first Android device. I would hate to swap it for another Droid if it was something simple.
