A:Answer Samsung makes Tab A 7" , Tab A 8" , Tab A 9.7" , Tab A 10.1" , Tab S2 in 8" & 9.7" & S3 In 9.7" ... You Might Want To Also Shop For Internal Memories Of 16 , 32 , or 64 GB Too As The 8GB Memories Don't Hold Alot ... If He Used A Nexus Tablet , It Had An Android Operating System Just Like The Samsung Does ... Newer Systems Go From KitKat , Lollipop , Marshmallow , Nougat , & Now Slightly Out Oreo ... All Those Systems Have Updated To Nougat Automatically Through Out The Year ... I Have 3 Samsung Tablets & Have Owned another 8 over the past 6 years ... I Have Traded Some In For The Newer Ones & Given A Couple Away To Family Because The Trade In Value Wasn't Enough ... I Personally Won't Use Any Other Tablet ... They Work Great , Work With My TV'S , And Some Of Them Have S-pens ... The Tab S3 Is New & Powerful For Work & The Newest Tab A(2) 8.0 32GB Is Really Nice Too . I Would Also Highly Recommend Some 2016 / 2017 Models Like The Tab A 9.7" 16 GB As Great & A Flagship A 9.7 Just Appeared That Uses A S-Pen ... I Used A Tab A 10.1 , But After I Got Spoiled With Using A S-Pen , I Wanted To Get The 10.1 With A S-Pen ... There Is Nothing Wrong With The Tab 7.0 , But I Really Can't Use One With Any Less Than 16 GB Anymore ... You Really Can't Go Wrong With Any Of Them ... Just Know That Tab S2 & S3 Are The Top Line & Are More Expensive , With The S3 Being The Newest ... Hope That Helps , I've Had Just About Every Model & Haven't Been Disappointed ... I Might Add , I Have Caught Wind Of Next Years Foldable Tablets That Look Alot Like Your Cell Phone ...
