Hey guys, I upgraded my Captivate to 2.2 two weeks ago and ever since the phone will shut itself off without making a sound (screen just goes black like the battery was pulled out) randomly. I do notice it never does it if the charger is plugged in. I also am having a problem with txting. Sometimes when I am replying to a txt to one person, it will sent the message to a random person in my contacts instead of the person I intended to send the txt to. Lastly, when I take a pic with the camera or download a pic from a txt, it takes awhile for it to show up in my gallery... None of these things were happening when it was still running 2.1. Thoughts? Thank you for your time.
