Samsung's high-end flagship phone, the Galaxy S24 Ultra, has a stunning design and potent hardware. Some users may have device faults as the phone ages, such as screen damage, aging batteries, or other hardware problems. Many people decide to disassemble the phone themselves in order to fix it in these situations. You can simply and safely disassemble the Galaxy S24 Ultra with the help of this comprehensive, step-by-step instruction from Phonefix.
I. Why Disassemble the Galaxy S24 Ultra?
Before you begin disassembling, it's important to understand why you might need to disassemble the Galaxy S24 Ultra. Common repair needs include:
· Replacing the battery
· Repairing a damaged screen
· Repairing or replacing internal components
· System recovery or hardware problem repair
Whether it's a battery issue or a cracked screen, disassembling the Galaxy S24 Ultra requires careful handling and the use of appropriate tools to avoid causing further damage to the device.
II. Tools Required for Disassembling the Galaxy S24 Ultra
Before disassembling your phone, ensure you have the following tools:
· Heat source tools: such as a heat gun or iOpener, to soften the adhesive on the back cover.
· Suction cup: for opening the back cover.
· Pry bar and pry tool: for separating the adhesive and removing components.
· Precision screwdriver kit: for removing internal screws.
· Tweezers: for removing delicate components.
· Lint-free cloth and isopropyl alcohol: for cleaning the screen and motherboard.
Ensure all tools are readily available and of reliable quality to avoid damaging the phone during disassembly.
III. Disassembly Steps
Step 1: Power Off the Galaxy S24 Ultra and Prepare
1. Power Off the Phone
Before disassembling, you must first power off the phone. Press and hold the power button and select the "Power Off" option to ensure the phone is completely powered off. Powering off the device helps avoid the risk of current leakage or short circuits during disassembly.
2. Remove the SIM card tray and stylus
Before disassembling, remember to remove the SIM card tray and other accessories, such as the stylus. These accessories may interfere with the subsequent disassembly work, so they need to be removed beforehand.
Step 2: Heat the edges of the back cover to loosen the adhesive
1. Use a hot air gun or iOpener
The back cover glass of the Galaxy S24 Ultra is held in place by strong adhesive, so you need to heat the edges of the back cover first to soften the adhesive. You can use a hot air gun or iOpener (a heating tool specifically designed for disassembling phones) to gently heat the edges of the phone, especially the right side and bottom, where the adhesive is harder.
Step 3: Create a gap and pry open the back cover
1. Use a suction cup
After heating, gently use a suction cup to hold the back of the phone, creating a small gap. It is generally recommended to start from the bottom or right side for best results. Once the gap is created, you can insert a pry bar and gently slide it along the four edges of the phone to cut the adhesive.
2. Be careful to avoid touching the buttons and camera
Be careful when cutting the adhesive; do not touch the power button, volume buttons, or camera area. Use tools gently to avoid damaging these sensitive components.
Step 4: Remove the Back Cover
1. Lift the Back Cover
After the adhesive has been completely cut, gently lift the back cover. At this point, check for any cables connecting the back cover. If so, disconnect the cables before removing the back cover.
Step 5: Disconnect the Wireless Charging Coil
1. Disconnect the Wireless Charging Coil
After removing the back cover, you need to disconnect the wireless charging coil. First, use a screwdriver to unscrew the screws securing the coil, then gently pry the wireless charging coil open and remove it from the phone's frame.
Step 6: Remove the Shielding Cover and Speaker
1. Remove the Motherboard Shielding Cover
Use a screwdriver to remove the shielding cover on the motherboard. Important circuit components are usually located beneath the shielding cover. Be careful during removal to avoid damaging internal components.
2. Remove the Speaker
After removing the shielding cover, continue removing the speaker. The speaker is usually secured by screws; handle it carefully during removal to avoid damaging the speaker or its connecting cables.
Step 7: Disconnect the Battery
1. Disconnect the Battery Connector Using a Pry Bar
One of the most critical steps in disassembly is disconnecting the battery connector. Gently disconnect the battery from the motherboard using a pry bar. This is crucial as it prevents current leakage or short circuits during subsequent disassembly.
Step 8: Disconnect the Flexible Cables
1. Disconnect All Flexible Cables
Next, using anti-static tweezers or a pry bar, disconnect the flexible cables connecting the motherboard to other components such as the display board, charging board, etc. These cables are tightly connected and require extra care.
Step 9: Remove the Sub-Board
1. Remove the Sub-Board and Small Components
After disconnecting all cables, use a screwdriver to remove the screws securing the sub-board, then carefully lift it. At this point, you can further disassemble other components of the device.
Step 10: Remove the Motherboard
1. Disconnect the Display Cable
When removing the motherboard, the first step is to disconnect the display cable. Then, gently lift the motherboard. The motherboard is a core component of the phone, so handle it with extreme care.
Step 11: Disassembling the Camera Modules
1. Disassembling the Main and Front-Facing Cameras
The Galaxy S24 Ultra is equipped with multiple camera modules. When disassembling these cameras, first carefully disconnect the main and front-facing cameras. To avoid damaging the camera modules, you may need to slightly heat the area around the cameras.
Step 12: Disassembling the Antenna Modules
1. Disassembling the Millimeter-Wave Antenna
The phone contains multiple wireless communication modules, including millimeter-wave antennas. These antenna modules are usually fixed to a bracket, so you will need to use a screwdriver to remove the fixing screws and carefully disassemble the antenna modules.
IV. Disassembly Tips and Precautions
1. Organize the Screws: During disassembly, be sure to organize each screw in its correct position so that it can be accurately installed during reassembly.
2. Clean the Old Adhesive: After disassembly, remember to clean the old adhesive from all parts and apply new waterproof adhesive during reassembly to ensure the device regains its waterproof function.
3. Handle with Care: Be careful when handling the device and avoid using excessive force to prevent damage to flexible cables and connectors.
