A:AnswerYes it does. And this is the one I picked up for mine: http://www.bestbuy.com/site/samsung-evo-plus-128gb-microsdxc-uhs-i-memory-card/5785406.p?skuId=5785406
I was able to fit a lot of video on there for my father to watch during a stint in rehab.
A:AnswerThis is not a phone its a tablet and this is one area I would recommend that you buy the Samsung case designed for it. Usually you can purchase a cheaper version, but the odd size of this tablet makes it to little for the 9 -10 in versions. The case is pricey gorgeous the 9.6 size, but I would recommend buying it because I have had no luck finding one that will fit.
A:AnswerYes. GPS, GLONASS and Beidou provide helpful location services. Without any wifi, you won't be able to generate turn by turn directions, points of interest (POI), etc., but the GPS works w/o wifi to show you your location in the Maps app, Waze, GPS+, MapQuest, etc.
