Datawind UbiSlate 7DC* is the wrost tablet ever I used. So many problems in this tablet after 4-5 months that is, HANG, Automatically restart, Display problem, speaker problem etc. This tablet only have 4 GB internal storage and 512mb RAM thats why the main problem is device hang. Not be all things about this tablet is bad Some good features also in this device that is HD movies run faster without buffering, Wifi connectivity range is too good. My opinion is, overall this tablet is not soo good but if you buy for watching movies youtube videos then it is good. But if you buy for gaming then don’t buy this tablet.
