I am using this since 9 months and trust me it really hangs a lot. Especially when u install more than 15 apps it starts hanging like hell. Sometimes I had to restart the tab so as to get the tab in the working condition. Camera is also not upto the mark.
Needs a lot brightness to take a clear image. Battery backup is also not good had to charge thrice a day to make it in working condition all the day. I will not recommend this tab as I got a horrible experience using it try some other brands in the same range which gives more functionality in less price.
