Samsung is my favrate brand in mobile compnay. This tab is worth your choice guys. If you want bigger screen with powerfull battery in a low price then I recomend you to go for this. Its a awsome tablet. I liked this tab mainly coz it has Android OS, v4.4.2(KitKat), Quad-core 1.2 GHz processor, Li-Po 4450 mAh battery. And Mainly its best feauters:-The tablet packs 16GB of internal storage that can be expanded up to 64GB via a microSD card. As far as the cameras are concerned, the Samsung Galaxy Tab4 7.0 3G packs a 3-megapixel primary camera on the rear and a 1.3-megapixel front shooter for selfies. Connectivity options include Wi-Fi, GPS, Bluetooth. Sensors on the tablet include Proximity sensor, Ambient light sensor, Acceleromete. it look great and gives a very good grip. This is a single SIM supported tablet( you need a micro SIM) . 3G is supported and you can also use this tab as a phone.
