Disassembly/Repair of the mobile device Samsung Galaxy A35 5G SM-A356 (Samsung SM-A356E, SM-A356E/DS, SM-A356B, SM-A356B/DS, SM-A356U, SM-A356U1) with each step description and the required set of tools.

⚠️️ Before disassembling, do not forget to turn your phone off.

Use the ejection tool (aka Needle) or Paperclip. Push the tip all the way into the hole until the tray ejects, and then pull the card tray out.

⚠️️ Pay attention! The tool must be inserted into a hole on the edge of the phone's housing. Do not press too hard. It may break the tray eject mechanism.

We recommend using a special heating device such as a separator machine, heat gun, or heating mat. It will simplify the process. You can use a home hairdryer, but you will have to make a nozzle by hand or have a suitable one in the kit to gently heat and concentrate the heat flow in the right place.

ℹ️️ The surface of the back cover must be heated to soften the adhesive underneath. The approximate heating temperature is 50° C / 125° F.

Use a thin plastic film or pick for separation. To facilitate the process, you can use isopropyl alcohol. It is often the most difficult to pass the tool between the parts to be divided. Choose the far edge from the FFC cables or buttons.

Do not use a lever or any force for separation that could damage the elements inside.

We protect the camera lenses with flexible plastic films.

Using a screwdriver Phillips 1.5 mm (PH #000), unscrew the ten screws.

Pry along the edges. Move an opening tool along the edge detach the clips and remove the cover with transmission lines and pads for antenna.

Disconnect the battery connector as soon as you can. Use a non-metallic or plastic tool to avoid any damage.

ℹ️️ The Samsung Galaxy A35 5G SM-A356 model has a battery EB-BA546ABY with a capacity of 5000 mAh (also known as a rechargeable battery).

Using a screwdriver Phillips 1.5 mm (PH #000), unscrew the eight screws.

Carefully remove the cover hiding the sub-board.

Carefully, preferably from the edge, disconnect the connectors and remove the inter-board cable connecting the mainboard to the daughterboard (also known as the sub-board).

⚠️️ Be careful when removing the cables from the connectors, the cables are pretty thin, and it is easy enough to break them or damage the contact tracks inside.

ℹ️️ An arrow on the FFC cable (flexible flat cable) indicates its correct position.

Using a Philips 1.5 mm screwdriver (PH #000), unscrew one screw securing the sub-board.

We disconnect the two connectors of the two coaxial cables and fingerprint sensor connector.

Remove the sub-board. It may be glued to the frame or attached with attachments like latches or hooks, so be careful.

ℹ️️ The sub-board contains a charging port (Micro USB), microphone, spring contacts for the speaker, vibration motor, and an antenna unit.

⚠️️ It is not necessary to insert the tool underneath when removing the sub-board. Internal components could be damaged.

We carefully disconnect two connectors of the two coaxial cables on the motherboard.

We disconnect the connector and remove the front camera.

Using a Philips 1.5 mm screwdriver (PH #000), unscrew one screw securing the motherboard.

Carefully remove the printed circuit board. There is no need to use a lever or try to reach the circuit board by force. Make sure that nothing is getting in the way or holding the circuit board.

The motherboard, also, may be attached with attachments like latches or hooks, be careful.

⚠️️ Do not bend the circuit board when removing it or push tools under it. Unbeknownst to yourself, you can damage components or cables from the inside.

ℹ️️  In the display frame remained: the earpiece speaker, loudspeaker, battery, and vibration motor.
