Hi, I am A. Stevens here to help with your question!
Could you tell me, are you using the Pattern unlock or a numeric passcode?
Please let me know when you return, so that we can continue working on this question. I will respond as soon as possible when I see your reply.
Hi am using numeric password
Were you syncing your device with your Google account?
No I didn't .
Unfortunately the only way to unlock the device without the passcode is if you had been syncing with Google, which you could then enter your Google account.
Had you backed up your device anytime before the passcode got messed up?
The only option at this time would be to Factory reset the phone. But you could restore your data if you have a backup.
Dame I didn't want to do that how do I do that factory reset
Press and hold VOLUME UP and Home(center) buttonPress Power until the phone vibrateWait until you see the Android logo then release all the buttons.Select Wipe data/Factory reset with VOLUME DOWN, press Power (right hand-side)Select YES -- delete all user data with VOLUME DOWN and then press PowerAfter format, press Power again to reboot phone. (select reboot system now)
Thanks for your help in this matter
Sorry there wasn't a better solution, but at least after restoring you should be able to use your phone agian.
