I can send sms texts fine, but when I receive one, it deletes all messages (emails, sms texts, google chats, etc) from the message list - including the sms text that was received. Happens from anyone that sends me an sms text. Using AT&T , v 4.2.2.89 OS
Note: also happens if I simply send myself an sms text.
You nailed it - my memory was filled up. I deleted the sample video and things are working again. THANK YOU!
Get a memory card... Anything. Even a cheap 256MB or 512MB. Just something that will give you some extra storage space. I had the same problem as you before and have not run in to a problem since getting the card. Just remember to change your camera setting to save pictures to the memory card instead of the phone. (That's what was eating up my device memory.)
