Motorola announced the Moto Razr 2019 flip foldable phone late last year and changed the perceptions of many concerning foldable phones. May fans soon realised that the foldable phone they needed wasn’t one that transforms into a tablet size when unfolded but one that becomes more portable like the Razr. The design tyle was featured by Samsung on the Galaxy Z flip that was launched just about two weeks back.
Popular Youtuber Zack from the channel JerryRigEverything has got his hands on the Razr 2019 and earlier on carried out a durability test on the device. The Youtuber has now published a teardown video of the Moto Razr 2019 showing the entire internals. He also did a comparison with the Galaxy Z Flip internals especially the hinge mechanism.
One thing that we can make out from the video is that the Motorola Razr 2019 adopts a different approach in its hinge design from that of the Galaxy Z Flip. Motorola’s adopted a simplistic mechanism with two inserts on the side acting as pivots. The hinge also has two gears on each half of the phone and springs on the side to help open and close the handset. The two halves are connected by a ribbon cable which Motorola was careful not to put too much strain by ensuring the fold at the middle of the screen bends as gentle as possible.
The hinge is pretty durable as shown n a separate durability test where it caved in after 27,000 folds even though Motorola touts durability of 200,000 folds. Another interesting thing is that the screen is pretty cheap to replace at around $200.
Also, Zack shows a better shot of the bristles that Samsung relies on to keep the dust out of the hinge in the course of the video. On the Razr, Motorola used sticky goop over important connections inside the Razr meant to catch dust and keep water away from the exposed electrical contacts.
Overall, the Motorola Razr 2019 internal layout is quite complicated as the foldable form factor made routing the cables tricky. The reviewers who tagged the Razr “impossible to repair” may just be right after all.
