A new teardown video highlights various differences between the Motorola Razr and the Samsung Galaxy Z Flip
A popular smartphone destruction-testing YouTube channel, JerryRigEverything, has posted its almost inevitable Motorola Razr 2020 dissembly video. During this process, the host Zach Nelson uncovered some interesting properties of this phone, some of which are found on no other mobile device on the market.
For example, Nelson found that the Razr possesses "goop" (the vlogger's word) on some of its internals, a clear viscous substances that is ostensibly there to protect some parts against dust and other contaminants.
By comparison, the other clamshell foldable phone, the Samsung Galaxy Z Flip, exhibits a series of tiny bristles along the interior of its hinge, which, as iFixit has demonstrated, may be less than effective in certain conditions.
Returning to the Razr, Nelson also pointed out the tiny, almost unique "cheesegraters" that cover this device's various chips. They are present in order to act as mini Faraday cages, and thus may protect these components from electromagnetic pulses.
However, it appears the Z Flip has the edge in hinge design: it has larger (and shinier) components for this purpose which may have been custom-designed by Samsung, whereas the Razr has rather conventional-looking little mechanisms - although they do at least act in conjunction with cunningly-hidden springs and mechanical gears that support the phone's opening action.
Otherwise, much like iFixit's pre-existing teardown of this same phone, it was demonstrated that it is possible to remove the inaugural foldable Razr's screen (although we also now know it is easier if you don't bend it in the wrong direction first). However, neither video seemed to adequately answer the question of any prospect of this phone's re-assembly afterwards.
