Our take on the Samsung Galaxy Tab S7 5G - 128GB - 11" - AT&T Unlocked - Mystic Black

The Galaxy Tab S7 5G is Samsung's 2020 flagship Android tablet: an 11-inch 2560 x 1600 screen at 120Hz, a Snapdragon 865+ chip, 6GB of RAM and 128GB of storage that expands to 1TB via microSD. It ships with the S Pen and adds AT&T 5G, so it works as a large-screen tablet on cellular data. The 8,000 mAh battery is rated for about 15 hours of video playback. At $299.95 at Walmart as of November 5, 2026, it sits well below what this tablet sold for new, though it is a 2020 model now several Android versions behind.
