Too many cmpoilments too little space, thanks!

If you forgot the unlock code for your phone, you should visit the store where you purchased it from or an authorized Samsung repair center and they might be able to help you unlock it. You might be charged for a service fee though. But before doing so, try to use number combinations such as your birthday, anniversary and other dates that are significant to you. This has happened to me twice already and fortunately for me, I was able to get the lock code correctly after so many attempts.
