A few days ago (5-6) I bought a Huawei P20 Lite. But I've just noticed that the screen has a "black" pixel error. Can I just change the device? Or do you want the device sent in like always else 100 times? Have read synonymous with black pixel error usually synonymous repair does not help.
Simply exchange
Can you give it back without a problem? → Warranty
You have to adhere to the legal requirements.
So report the defect to the seller.
He has the right to repair or replace the device.
But that decides the seller.
Presumably, it will first be sent in and tested.
PS: After two unsuccessful remedies DU have the right to withdraw from the purchase. Then everything is reversed.
