catatan:

• Factory reset hanya akan menghapus account, system & aplikasi setting
  
• Hard reset akan menghapus semua files dalam hp & settings di internal memory handphone anda, atau sama dengan memformat ulang firmwarenya mengembalikan setingan awal Samsung Android Galaxy Young. Kalo udah pencet tombol ini langsung hardreset, ga ada pilihan batal.
