The Motorola Atrix 4G is still a very fast quality Android phone, the only issue is the fact that it bogs down bad after heavy use. After you have had an Atrix 4G for about six months to a year it would benefit you to do a factory reset. You can easily format internal storage but to actually get the Atrix 4G back to the condition it was the day you bought it you need to do a hard factory reset.
NOTE: This will completely wipe the entire device including all apps, photos, videos, etc. Backup anything you don’t want to lose before doing the factory reset.
How to Completely Reset your Motorola Atrix 4G:
Turn off your Atrix 4G
Turn on the Atrix holding the Vol down button
When you see fastboot at the top of the screen release the vol down button
Press vol down until you get to “Android Recovery”
Press power button to select “Android Recovery”
Once you see a yellow triangle press both vol up and vol down
Use Vol down to navigate to Factory Data Reset
Press Power to select then select Yes to confirm the same way
Wait for the process to complete and go back to the menu
Press power to select “Reboot Device”
Congrats once it reboots you will come to the MotoBlur screen!
