I purchased a Datawind ubislate 7DC* tab after impressed by Naaptol tv shop online show. But to my didappointment, the battery of the tab is out within 3 months time.( purchased on 5th Aug 2016).ehen I contacted naaptol they directed me to Datawind. When I contacted Datawind, they are still dragging me to replace the battery after my several mails to them. The tab is also very slow, and needs to be charged frequently as charging not lasts even for 2 hours. The tab gets heated during use. Totally it is a wate of money.
