YouTuber Zack from JerryRigEverything is back with the typical sequel, a disassembly of the Samsung Galaxy Z Fold4. The video is posted below.
If you prefer seeing the insides of phones to their exteriors, watch this video. The foldable Fold4 is more exciting than a slab-type phone, and Samsung claims to have changed the hinge. Yes? See video.
The Galaxy Z Fold4’s flexible inner screen is constructed of several layers, which were disclosed during the deconstruction at the cost of the display never operating again. It may be acceptable with folding in one direction, but not in any other. New metal plate and cutout for under-display camera are also included.
Even though PBKreviews gave it a low score for being easy to fix, they make it look easy to take the phone apart and put it back together again. In this video, he doesn’t take off the bendable screen, so we don’t get to see the hinge. This is important because Samsung gave the Galaxy Z Fold 4 a better hinge mechanism that could have been used in the Galaxy Z Flip 4.
40 screws secure the new gearless hinge. It has three metal-plate-connected pieces. The new mechanism has no moving parts, unlike the Galaxy Z Fold 2 and 3. Samsung coated the hinge with bristles to keep dirt out.
Glue and lack of pull tabs make battery removal difficult.
Overall, disassembling the Galaxy Z Fold 4 is hard and time-consuming. Given the complexity, self-repairs are implausible. For now, leave this work to Samsung’s pros.
