I've received tablet with defective screen
Conclusions: I've received tablet with defective screen. Seller was not cooperative at all with the refund - he was responsive to my messages but didn't refunded me until the end. Thanks to ali representative via dispute I've managed to recover part of my money, so I can buy a new screen and try to replace it. The tablet is not bad especially for that price, but if you receive defective one like me you can depend only on ali dispute, seller will try to slow your refund as long as possible. I'm very disappointed and I will definitely not buy from this seller again :(
