Just bought one of these last week to replace my 2014 10.1" galaxy tablet. Not as powerful as that one, but a really nice tablet. I love it, and found a really nice fitting case that turns it on and off automatically. This is well worth the price, and can accept large capacity cards to expand its storage.
Does this one come with the S pen?
Sorry, no S pen.
What GPU does it have?
Per the vendor: Mali-T830
Nice refurbished tablet. Mine looks and performs like new for $100 less.
