Anonymous users2024-01-23Hello landlord!
You bring the machine, invoice, warranty card, ID card to Samsung after-sales service, you tell the technician that the machine suddenly appears on the screen, let the technician help you identify it, if he identifies it is artificial, you say put it in the pocket and take it out. (A small panic, not much of a big deal) screen prices range from about 1400.
