Hi all, im new to Android and have just purchased two Neuropads for my two boys and was wondering if I can "lock it down" or configure some for of profiles so I can limit what they can see/do. Is this possible?? (I have tried searching the forum for this topic or something similar but had no joy) the model number is: Nexus 7 and Android version 4.1.1 amy advice would be greatly appreciated.
