Repair parts Samsung Galaxy Z Fold 4

Browse our selection of parts for the Samsung Galaxy Z Fold 4, the 2022 foldable with a 7.6-inch inner screen and a 6.2-inch outer screen. This range is designed for individuals who need a specific part and repair shops looking for anything from the Service Pack outer screen to flex cables, brackets and internal boards. This model has two screens, two batteries and a bonded rear glass panel, so choosing the right part helps you avoid opening the phone twice.

From SM-F936B to SM-F936U1: how to check whether your phone is a Samsung Galaxy Z Fold 4

You can find the model number under Settings, About phone, and on the label on the box. All Galaxy Z Fold 4 models share the SM-F936 root; the suffix varies according to the intended market.

• SM-F936B and SM-F936B/DS: European and international variants, the most common in Spain. The /DS suffix indicates dual SIM.
• SM-F936U and SM-F936U1: US carrier and unlocked versions.
• SM-F936N, SM-F936W and SM-F9360: other regional variants, including those for South Korea, Hong Kong and China.

The parts in this category are listed for the F936. Its predecessor, the Galaxy Z Fold 3 (SM-F926), looks very similar, but its outer screen has a different resolution and aspect ratio. The only part in this range listed as compatible with several generations is the 4 MP camera, which works with the Fold4, Fold5 and Fold6; for all other parts, check that your code starts with SM-F936.

Service Pack, dual cell and OEM cover: what to choose for the Galaxy Z Fold 4

Why the outer panel is sold as a Service Pack

For the outer screen, we offer the original Service Pack outer screen for Galaxy Z Fold 4 F936. It is a 6.2-inch Dynamic AMOLED 2X panel with a refresh rate of up to 120 Hz, protected at the factory with Gorilla Glass Victus+. As an Original part, it retains the specifications of the panel fitted to the phone at the factory.

The Service Pack format is supplied by Samsung to its repair network and usually comes pre-fitted to its frame. This is particularly important for this model: the outer glass is set into the metal frame and often breaks when separated, so reusing the old frame carries a risk. This part is for the outer screen only, not the foldable inner screen.

Two cells, one in each half

The Fold 4 does not have a single battery, but two cells with the part numbers EB-BF936ABY and EB-BF937ABY, which together provide a typical capacity of 4400 mAh. The Premium 4400 mAh battery compatible with Samsung Galaxy Z Fold 4 is listed with both part numbers. Before ordering, check the product details to see whether it includes the full set or a specific cell.

Both cells are held in place with plenty of adhesive and no pull tabs, which Samsung did not add until the Fold 5. We have found no documented reports of a non-original battery warning on this model after replacement. Even so, check the charge and capacity shown by the system before closing the phone.

Bonded rear glass in three colours

The OEM back cover with camera frame, adhesive and lens for Z Fold4 is available in Gold, Grey and Black. As it includes the camera frame and lens, one part lets you replace both broken glass and a damaged trim, while the included adhesive means you do not need to prepare the bond separately.

The cover is not removable; it is bonded to the chassis and must be lifted with heat. If the glass is badly shattered, the job takes longer. The cover also provides access to the battery, so if you plan to replace both parts, it is best to have them ready before opening the phone.

Cameras, buttons and internal parts

• Rear camera lens for Z Fold4: glass only, for when the frame is in good condition.
• Original rear camera lens and frame: for when the trim is also dented or bent.
• 4 MP camera for Z Fold4, Z Fold5 and Z Fold6: according to the official specifications, the camera under the inner screen is 4 MP, while the outer screen camera is 10 MP. Check the part you are replacing before ordering.
• Original volume button and volume button flex cable for Z Fold4: the first is the physical key; the second is the circuit that connects it.
• SIM reader board for Z Fold4 and mainboard retaining bracket with speaker: internal parts commonly requested by repair shops.

Fingerprint sensor in the side button and around 80 screws: key points about the Samsung Fold 4

The Fold 4 fingerprint reader is built into the side button, not located under either screen. Replacing the outer screen therefore does not affect fingerprint unlocking, and the volume flex cable is a separate part from the reader.

We have found no verified information that this model restricts the outer screen, battery or cameras by serial number when they are replaced outside an authorised service centre. What does affect the repair is the assembly: teardown guides list around 80 screws and several bonded parts. The practical takeaway for a repair shop is to have all the parts ready before disassembly, as each time the phone is opened, parts must be unbonded and resealed, and its factory water resistance can no longer be guaranteed.

Frequently asked questions about repairing a Samsung Galaxy Z Fold 4

Do both batteries need to be replaced at the same time?

It is not essential, although repair shops usually replace both. The two cells degrade at a similar rate, and accessing each one involves removing bonded components, so replacing just one often means opening the phone a second time.

Will an outer screen from a Fold 3 fit?

No. The SM-F926 uses an outer panel with a different resolution and aspect ratio, so it is not compatible with the SM-F936.

Will replacing the outer screen affect the fingerprint sensor?

No, as the sensor is in the side power button. The screen is not involved in fingerprint recognition.

Is the 4 MP camera the one for the outer screen?

On the Fold 4, the 4 MP camera is located under the inner screen, while the outer screen camera is 10 MP. Compare the removed part with the one shown in the product details to confirm that it is the module you need.
