Tab seller is ORENIZYS. I bought 10" android tablet. Within 12 days Portrait screen mode turned to Landscape mode and can see Half of the screen only. It is getting charged up to 10% only. Even if we charge more than 4 hrs also percentage of battery is 10% only. 1. Screen malfunction. (Touch screen not working) 2. Battery is not working properly (Seller force me to use other charger. I charged using Samsung charger also no use) 3. Seller responsibility is very poor. 4. I cannot use the product totally. I need immediate replacement with other branded Android Tab. If there is any cost variation, I am ready to pay. or return my money by voucher. I can use that money to purchase other useful item.
