Depends on the product. And it depends on the merchant that Lazada.ph is sourcing from. I would advise not to purchase anything from Lazada.ph - first of all, you're not sure whether it's authentic or not. Secondly, you don't get a warranty. Thirdly, it's VERY difficult to return and receive a credit. Believe be, I've been there, done that.

Yes the product is authentic, i was already 3 weeks ago in the seervicecenter for repairing, But after 1 week i have the same error on the phone.

Not sure if fake or authentic but surely u can return that and get your refund, just make sure its still in original packaging upon returning.
