Bought two for daughters Christmas presents. On the 29th of dec one has already failed. Wal Mart has a extended return policy for holiday gifts. Normally tablets have a 15 day RETURN POLICY''' from purchase date. With holiday gift policy I have until Jan 10 ..I printed wal marts easy return receipt and there web page has tablets in stock.Now I have to make the actual return. I plan on reinforcing the usb before charging. The tablet performs very well BUT '''UPGRADING THE ANDROID OS is a must do.My daughter loves her tablet and only wants to exchange.
