I know this has been posted many times, but I don't have time to go find a thread like this, so if someone could just help me out here Every week my call log/some messages get deleted off my phone. Can anyone tell me how to fix this? Thank you.
Low memory is probably the culprit. Unless you have 12,000,000 file free bytes, you are low on memory. Your BB is designed to delete logs & messages to free up memory to continue to operate.
