If you have any data saved on your device will want to back this up being this will restore all data.
To Hard Reset the Samsung Ace you will:
1. Remove the Storage card from the device if one is present.
2. With the phone powered off:
*press and hold both right and left sofkeys
*While both softkeys are down you will press and hold the power button until the phone powers on.
3. As the phone begins to power on you will release the softkeys.
4. When the phone powers on you should see an alert on the screen (a white screen with blue letters). If you do not see this screen you will power the device on normally , turn it off again, then repeat steps 2 & 3.
Hope this helps.
