How to protect my note 3?

Hi, sometimes my children play on my phone Galaxy Note 3 but I have to worry about my phone since they have drown one spare battery I just purchased from mpj and wiped my phone twice already. My question is how can I protect my Note 3 and keep my children away from some bad websites?


Thanks in advanced.
 
Hmm; iPhones use iTunes and iCloud for backups. I am sure there are other SYNC programs which can be used for your Note3
