Samsung tablet in case (Cheshunt EN8)

Hi,I have a Samsung tablet in a brown faux leather case.

My sister gave this to me a while back for my son,however she could never remember the password to open it.
I had intentions of unlocking it however ,didn't bother in the end as son preferred to use larger device.

Still works as far as I know but taker will need to make own arrangements to have it unlocked and reset,or maybe you know how to unlock it yourself.
Collection only.thanks.
