Battery

The Battery is a Lithium-ion (Li-ion) cell and must be handled carefully. Improper removal can damage the cell, causing it to ignite and cause injury:

• Only hold the Battery from the center sides.
• Do not squeeze the Battery or use any unauthorized tools when handling it.
• Do not hold the Battery by its flex connector, as this can accidentally short the leads.

Caution: When handling the Battery, be careful not to puncture or damage it.

Back Cover

Galaxy S24 Series devices have a Back Cover that is bonded to the frame; it can only be removed using heat.

The Back Cover has double-sided tape located on the edges that must be replaced every time the Back Cover is removed.

On S24 & S24 +, there will also be a 3 rd Mic tape that will also need to be replaced every time the Back Cover is removed. This tape could be on either the Back Cover or Rear Assembly.

Electrostatic Discharge Precautions

Before you begin disassembly, make sure that all ESD precautions are met.

This includes:

• Wearing an ESD Strap which has passed all required tests
• Wearing Anti-Static Gloves
• Working over an Anti-Static Mat

Swollen Battery Precautions

A swollen Battery may cause a device to bulge.

• Before disassembling the device, make sure that there are no signs of Battery swelling
• If the device has a swollen Battery, DO NOT heat the device
• Heating a device with a swollen Battery can cause further damage to the device and cause the Battery to ignite and cause injury
• In the event of a swollen Battery, use only 99% Isopropyl Alcohol to carefully separate and remove the Back Cover

Eject SIM Tray

To prevent damage to the Sub PBA, the SIM Tray must be removed before starting disassembly. The SIM Tray is located on the bottom of the device.

Replace the Orange Seals

To prevent damage to Back Cover, replace the orange seals with the blue seals on the AOD.

To replace the orange seals:

• Gently remove the orange seals by pulling them off the upper plate
• Align the new blue rubber seals and press down on the corners, making sure there are no cracks or tears in the seals
• Run your thumbs along to sides of the rubber reals to secure the seals in place

Configure the AOD

Set the AOD to the following temperatures to remove the Back Cover:

• Heat the upper to 75°C and the lower to 65°C for five (5) minutes
• The heating process loosens the adhesives that hold the Back Cover on the device

Device Placement

• Place the device face down in the AOD
• Align the device properly as shown depending on the model (See photos)
• Once aligned, lock the device in place by twisting the Torque Wheel, then lower the upper plate
