There were reports going around suggesting that Samsung was testing OLED screens from Chinese giant BOE as a means to procure a cheaper alternative for the upcoming Galaxy S21 series. These displays were meant to be present in some models of the Galaxy S21, giving more breathing room for Samsung’s own production facility and reduce manufacturing costs. However, a fresh report says that Samsung might continue using its own displays for the upcoming flagship family.

A foreign media report shared by tipster Ice Universe has been shared on Twitter, detailing how BOE failed to pass Samsung’s display quality testing process. It appears that the display samples were unable to pass the first testing phase and will not be used in the Galaxy S21 series. Earlier, display market research firm DSCC had reported that BOE intends to supply 6.67-inch OLED panels to Samsung, but after this update, it looks like that isn’t going to happen anymore.
