JerryRigEverything is a well-known YouTuber who makes tear-down videos of popular and trending smartphones/devices. Now, he got a brand new Samsung Galaxy S22 Ultra on hand.
From the starting of the video he separated the rear panel from the frame by cutting through adhesive, he notes that the glass panel and its camera cutouts are all permanently affixed together. If one of the glass camera lenses were to break, it would require a complete replacement of the back panel to fix.
In the second stage he removed the wireless charging coil and the plate covers from the upper and lower boards, he shows some of the speaker assembly and the USB-C port gasket that aids in water resistance.
After showing the massive quad-camera assembly and showing what’s behind the mainboard, he notes that Samsung is using excessive adhesive to keep the battery in place.
Then there’s the S Pen silo, which is more like a channel. It’s covered with a thick plastic plate that’s glued shut to keep water out of the phone’s internals while allowing it to enter the silo. At the top of the channel there’s a coil that recharges the S Pen’s capacitor.
