My mega had a prompt for me to update the software this morning. I opted to postpone it for 6 hrs (you have this option) until I know more about it. It said once you update you cannot downgrade to old version. It also says it's for improved stability ,but my mega works like a champ. It also says it's for Compatibility with Galaxy Gear. It's 77.83 MB Anyone have any additional info ? Thanks PS: I'm not rooted and it's a MetroPCS Mega.
