Disassembly/Repair of the mobile device Samsung Galaxy A10 SM-A105 (Samsung SM-A105F/DS, SM-A105FN/DS (Global); SM-A105G/DS; SM-A105M/DS) with each step description and the required set of tools.

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 tray of SIM and Memory card (Micro SD) 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.

Using a spudger or a plastic pick, carefully, around the edge, detach the back cover clips, and remove it.

Do not insert the tool deeply or bend it. Otherwise, the housing may be tampered with or damaged.

⚠️ Be careful when opening the cover from the volume and power buttons side. Thin cable and fragile buttons are straightforward to damage.

Using a screwdriver (Phillips 1.5 mm PH000), unscrew the 7 screws.

ℹ️ Be sure to note the location of the screws before disassembling. When assembling the device, screwing the screw in the wrong place may damage the device or its part. To avoid damage, the removed screws and individual pieces (as gaskets or brackets) must be laid out in the appropriate order, or the screws and their holes in the phone must be marked with colored markers.

Remove the covers with antennas that protect the printed circuit board (PCB). Try to lift the covers by the edges and not push anything between them to not accidentally touch or short-circuit anything on the PCB.

⚠️ It is crucial while reassembling, checking the spring contacts on the board, and the contact pads on the cover match and touch. Otherwise, signal loss or signal may be quite weak.

Disconnect the battery connector as soon as possible.

ℹ️️ The Samsung A10 (2019) model has a battery EB-BA750ABU with a capacity of 3300 mAh, which is also compatible with the Samsung A750 and M105 models.

⚠️ It is highly recommended to disconnect the connector to avoid possible short circuits during disassembly.

Also, try not to use a metal tool to disconnect the battery connector or do it very carefully.

Using a screwdriver (Phillips 1.5 mm PH000), unscrew 8 screws.

Remove the loudspeaker assembly with antennas.

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.

Disconnect the coaxial cables connectors on the daughterboard.

⚠️ Do not pull on the cable or pry it with a sharp tool, the connectors are pretty weak and break easily, or the cable falls out of the end (lug).

Remove the sub-board. Because it is glued to the frame with metalized tape, to facilitate the process, the board can be slightly heated.

ℹ️️ The board contains a system Micro USB 7pin connector (MC-367), microphone, headphone jack connector (mini jack) 3.5 mm, pins for a loudspeaker, and antenna unit.

Pry up the connectors of power volume buttons cable, display module cable, and two coaxial cables.

⚠️ 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.

Using a screwdriver (Phillips 1.5 mm PH000), unscrew one screw on the motherboard.

ℹ️️ Be sure to note the location of the screws before disassembling. When assembling the device, screwing the screw in the wrong place may damage the device or its part. To avoid damage, the removed screws and individual pieces (as gaskets or brackets) must be laid out in the appropriate order, or the screws and their holes in the phone must be marked with colored markers.

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

⚠️ 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.

Disconnect connectors on the motherboard and remove the rear and front (selfie) cameras.
