Using Xiomi Mi Pad from last 3 months. Though not a calling tab but still I decided to buy it as it attracted me as it is from Xiomi. Excellent in use. I use it for my official purpose. I have wifi connectivity in office so no problem of not having sim card facility. It is not so big just 7.9 which makes it easy to carry and it is very handy. It has a super ram of 2gb. So no lagging in playing high data games. It has an internal memory of 16gb and expandable upto 128 gb. It has an excellent resolution of 2048x1536 pixels with ips display. It has Android kitkat with 2.2 ghz quadcore ARM cortex A15 processor. A front camera of 5 mp but quality is like 8 mp. Good selfies are catched. A rear camera of 8 mp which is also better than any other 8mp camera. Has Bluetooth connectivity, light sensor, a compass, G sensor, a 3.5 mm jack with superb music sound. The battery backup is more than excellent with a giant 6700 mah Lithium polymer battery. Very good product at a very good price.
