Disassembly/Repair of the mobile device Samsung Galaxy A10s SM-A107 with each step description and the required set of tools.

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

Use an eject 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 turn it over.

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.

⚠️ Look in advance in the picture for the cables, location for inter-board, touchscreen, display, buttons (if any) under the cover to not damage them accidentally.

Disconnect the connector fingerprint sensor and remove the back cover.

Using a screwdriver (Phillips 1.5 mm PH000), unscrew 3 screws and remove the bracket holding the connectors.

Disconnect the battery connector as soon as possible.

ℹ️️ The Samsung Galaxy A10s SM-A107 model has a battery SCUD-WT-N6 with 4000 mAh capacity (aka rechargeable battery).

⚠️ 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 rechargeable battery connector or do it carefully.

Using a screwdriver (Phillips 1.5 mm PH000), unscrew 9 screws.

Remove the loudspeaker assembly with antennas.

Disconnect the coaxial cable connector, cables to the mainboard 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. It is glued to the frame with metalized tape, so to facilitate the process, the board can be heated a bit.

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

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

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

Remove the cover with antennas. 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.

ℹ️️ On the upper cover, you can see the metalized coating on the plastic in the form of tracks and contact pads.

⚠️ 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.

Pry up the connectors of the display module cable, inter-board cable, and coaxial cable.

Also, disconnect the connectors and remove two rear cameras and one front (selfie) camera.

⚠️ 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.

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.
