Samsung Galaxy Z Flip 4 5G Inner OLED Assembly with Frame

It often starts small: a thin line of dead pixels along the fold of a Galaxy Z Flip 4, or a bubble in the screen's protective layer right at the crease. Over weeks of opening and closing it grows, until a strip of the inner screen stops showing anything at all. On a folding phone, the inner display is the part that works hardest.

This inner OLED assembly comes with the frame, for the Galaxy Z Flip 4 5G, US and international versions, with Blue, Bora Purple, Pink Gold and Graphite frames. It's sold as an aftermarket part, since the listing gives no quality grade.

When the inner screen needs replacing

Typical reasons are a line or dead strip along the fold, cracks from something caught when the phone closed, black or flashing areas after a drop, and touch that fails near the hinge. A screen protector that has lifted and taken the panel surface with it is another common case.

Because the panel comes in its frame, the internal parts move across into the new frame. Don't peel the protective layer on the new screen. Test display and touch in several fold positions before closing up.

With a new inner screen, the Flip 4 folds and shows a clean picture again, from edge to edge.
