I am glad to announce that Motorola Droid 4 users can now upgrade their smart-phones with something useful. Unfortunately, this is not Ice Cream Sandwich but it does bring a number of new interesting features, improvements and one of the most important ones is improved battery life. So, in the changelog you will find: Enhanced loud call end and connect tones over Bluetooth Power On function has been fixed Improved battery life Improvements made to reduce touch screen lockups, device sluggishness, and blank screen lockups Keypad backlight only launches when needed Successfully receive Visual Voice Mail notifications MotoCast widget can be added to the homescreen and thumbnail view Improved text message delivery when using the Messaging application Improvements to WiFi connectivity Reply With Quote If you haven’t got your update notification yet, I think it is the highest time to go to Setting > About > System Update and tap “Update Now” button.
