And after 5-7 minutes we can proceed to disassembly. To detach the back cover, we need to slightly lift the edge, because the cover is recessed a little. To do this, we use a thin metal tool. Carefully pry up the edge and slip a plastic film into this place. We run the film along the cover to detach it.
We should always be careful around the side buttons and the fingerprint sensor, because in this area may be located cables and they can be damaged.
We also need to be careful around the cameras. As the back cover is detached separately from the cover of the cameras, the back cover will be glued around the cover of the cameras.
And the camera cover is attached to the middle cover by clips.

Step 6. Open the middle cover
We can move on to detach the middle cover. We use plastic film, run the film into the gap near the cards tray hole and gently run it along so that we can use a thicker tool. This is not the way to detach the clips with this film on this model. As always, we need to be careful around the side buttons and a fingerprint sensor, on the corners and around the cameras.
On the cover we have contact pads and antenna transmission lines. Also the speaker is located in the middle cover.

Step 11. Remove the daughterboard
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, headphone jack port, 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.
