I buy a unit of this model and I’ve been using it for a week there’s no problem using it except for the internet connection but I already fix it by setting it(some setting change)but the center button suddenly don’t work, it function when you press it(goes back to home page) but when you touch it to perform a BACK command it doesn’t work and even doesn’t vibrate too.
I am now using the smart touch option but it is not as convenient as the back key not a device for its pricei would suggest not to go for it you can get many other good devices at this price range the biggest problem for this device in india is the service center
My recommendation is not to buy this device.
