Hi guys, new gtab here. Just bought it last week and wanna ask you guys about warranty isssue here. The seller said it was original sat and not ap set. But when i sms through i warranty it replied that i need to ask retailer to activate it. Then i check the box but it got no blue sticker. Is there other way that i can check for it originality from samsung msia. And also when i restart it show t-mobile logo.
