In this segment of the video, the creator begins the disassembly of the Samsung Galaxy S22 Ultra. They emphasize the importance of subscribing and following on Twitter for updates and mention that necessary tools are linked in the description. The disassembly starts with removing the SIM tray and S Pen. Heat is applied to the back plate to loosen the adhesive, followed by using a plastic pry tool to remove the back plate. The video then details the removal of the glass camera lens covers and explains the purpose of the slot by the camera bezel frame.
Next, 15 Phillips screws are removed, and the flex cable for the wireless charging coil and NFC antenna are disconnected, along with the graphite film from the bottom speaker assembly. The creator highlights the locations and functions of components like the wireless charging coil, NFC antenna, and the graphite film for heat transfer. The battery cable is disconnected, followed by the cable for the autofocus and light sensor.
The top plastic cover, containing antenna lines, is then removed. The front-facing camera cable is disconnected despite being glued to the frame. The creator identifies various antenna cables, including the 5G millimeter-wave antenna cables and those connecting the top and bottom phone components. Finally, the main board is lifted out, revealing details about the various camera lenses and the secondary microphone.

In this part of the video, the host discusses the internal components and disassembly of a smartphone. They describe the multi-layer main board design, identifying key parts such as the LED flash, camera flex cables, back plate microphone, and proximity sensor. The graphite film on the back shield is removed, revealing thermal paste on the processor and RAM, noted as Samsung’s new “gel tim.” The RAM is on top of the Snapdragon 8 Gen 1 processor, with storage above it. The top speaker assembly, secured with two Phillips screws, is then removed, showing foam balls and thermal pads, and the bottom speaker assembly is described similarly, including the location of the linear vibrator motor.
The host explains that for screen replacements, it might be more challenging to align the screen with the flex cable without fully disassembling the phone. They suggest that although it is possible to replace the screen from the front, removing the back plate and bottom speaker assembly might ensure the flex cable connects properly. The process continues with disconnecting and removing the sub-board, noting the locations of the primary microphone and the SIM reader.

In this part of the video, the presenter explains the process of disassembling various components of a Samsung phone. First, they mention applying isopropyl alcohol to the edges of the battery to loosen the adhesive before prying it off. They then provide a closer look at the 5000 mAh battery and the stainless steel vapor chamber beneath it. The in-display fingerprint sensor is revealed once the protective film is removed. To access the S-Pen enclosure and 5G antenna, heat is applied to remove covers and adhesive. Key details include the location of the power button and volume key flex cable, the rubber gasket and mesh filters for the speakers, and the liquid damage indicator. The screen removal process is noted to be particularly challenging due to strong adhesive, and the fingerprint reader is soldered to the main screen, indicating replacement screens come with the fingerprint reader pre-installed.

In this part of the video, the presenter removes the screen to reveal layers of graphite used for heat transfer. Upon peeling away the graphite film, the stainless steel vapor chamber is visible. Despite its copper-like color, it is confirmed to be color-treated stainless steel through Mohs hardness scale testing, showing scratches at a level six. The phone receives a repairability score of 7.5 out of 10. The device is then reassembled, new adhesive is applied, and the backplate is reattached. Finally, the phone is flipped over, powered on, and the repair is complete.
