When you start up the phone type *2767*3855#...this will fully reset the phone and remove all codes on the phone.

Format sch-u470 samsung juke

Delete some unnecessary files in your phone memory like images and videos. Go to your phone gallery and delete some of those. And if you want to use the memory card as phone message storage then go to Messaging - Option - Settings - Other and then Memory in Use, select your memory card.

But if your phone is infected with a virus then you need to format your phone. One sign of infection is your phone keep sending a message randomly from your contacts without your consent.

Use these code and enter it to format your phone:
*#7370# and then the default code is 12345

Take note: Make sure you back-up your contacts or any other important inside your phone.

Hope I make it clear and does makes sense

Pass word

Phone Security Code:
This locks the handset, as opposed to the sim card. You can also set some handsets to only accept a “new” sim if the phone security code is entered. To reset it, you need the Master code code:
Master Reset Code
Sometimes known as the Master Code, this allows you to unlock a handset if you have entered the Security Code wrongly too many times.
The default security code for Nokia is 12345
