Update does NOT clear cache! Easy non software fix!
Attention**Droid RAZR and Droid RAZR MAXX Ice Cream Sandwich updates. Users*have been*complaining about issues*with the Ice Cream Sandwich update that Motorola and Verizon pushed does not wipe the cache of both devices.
Wiping the cache is something that is required to help keep applications and tasks stable. It’s also probably the reason many of Droid RAZR and Droid RAZR MAXX owners have been complaining about crashes and the devices seemingly taking on minds of their own.
It’s also a requirement for rooted users when moving from ROMs.
Here are step by step instructions on how to wipe the cache of both devices clean, a move that should return the Droid RAZR and Droid RAZR MAXX to normal.
1)*Press and hold the Power button and turn the phone off.
2)*When the screen turns off, press and hold Volume Down and Power.
3)*When the white HBOOT screen appears, use the volume button to move down to “RECOVERY.”
4)*Press the Power button to select “RECOVERY.”
5)*When the triangle and exclamation appears, hold the Volume Up and Power button at the same time.
6)*Using the volume button, scroll down to “Wipe cache partition” and select it.
7)*Select “Reboot system now.”
