Motorola Droid RAZR update to improve on 3G/4G connectivity
As you can see in the changelog above, there have been several fixes and improvements made to your device, such as improved camera features and quality, SIM card error notifications has been fixed, improvement in 3G/4G connectivity and more. As with most updates, they’ll probably be rolled out in batches so fret not if you have yet to receive the notification informing you of an update.
If some of these bugs are still bugging the heck out of you (pardon the pun), you will be able to check manually for the update by going to your phone’s Settings > About phone > System updates in order to check for it.
