I bought this product before 6 months first 2 month it works properly then suddenly it hangs and in between tab gets heated.
So this problem can be solved by rebooting the tab. So if u reboot the tab by clearing all the memory in it works properly again for 3 to 4 months.
So every 4 month we have to reboot our tab 3 T211 to work properly. Then it runs in 4.1 Android OS(jelly bean) and it has 3 megapixel but has no flash in primary camera. But it has a good build quality and good battery life.
