Hello everyone, Welcome back to geardo,
Today we will show you how to replace the lcd screen on the Samsung Galaxy A12 Mobile
Phone.
To start, we need to have the right tools to proceed with the repair, which You can
find in the description.
First, turn off the phone, take out the Sim tray, and follow the back cover removal.
To remove the back cover, create a gap near the sim slot or charger port using a picker
or card pry tool.
Insert the card pry tool and gently move around the phone to release the plastic clips on
the frame.
Be gentle when taking out the back cover; the fingerprint sensor is attached to the
back cover.
Next, take out the logic board cover by undoing six screws.
And then, disconnect the battery plug and followed by
the fingerprint connector.
Now, the back cover can leave from the body.
Next, disconnect the main flex and remove the battery from the body.
First, apply little heat to soften the glue on the battery.
For this, we are using a heat gun.
Once you feel the heating is enough, use a card pry tool or similar to cut the adhesive
under the battery.
And Once you have some space, use a pry tool or similar to lift the battery.
Next, take out the logic board by undoing the screw and disconnecting the antenna head.
Next, apply little heat and take out the earpiece from the board.
Next, apply little heat and take out the vibrator motor.
Next, apply little heat and take out the button flex cable.
Next, move to the bottom and undo seven screws to take out the speaker cover.
Next, disconnect the lcd connector and antenna head from the charging port board.
Next, pull out the charging port board from the body.
Next, take out the Speaker buzzer from the body.
Now the only remaining part is the broken front screen assembly with the frame and buttons.
For the replacement, there are few different screen types in the market.
The most common is the Original service pack screen, which comes with the frame and buttons.
There is another type; it is original but without the frame.
But the repair job is a bit difficult and time-consuming, and the price difference is
not that big.
And also, there are refurbished, used, and aftermarket screens with the frame and without.
I would recommend you to go for a screen with the frame & buttons installed.
It can be original, refurbished, used, or aftermarket.
And this type is commonly available to purchase.
Next, on the new screen frame, start placing removed parts.
First, place the Button flex on the frame.
Next, place the earpiece and vibrator on the body.
Next, place the logic board by securing
the screw.
Next, place the battery with adhesive.
Next, connect the main flex into the board and place the speaker buzzer at the bottom.
Next, place the charging port board in the body, secure the lcd plug, and connect the
antenna heads to the logic board.
Next, place the speaker cover by adding seven screws.
Next, connect the battery and fingerprint plugs into the board.
And then, secure the logic board cover by adding six screws.
Finally, Snap in the back cover and run through the sides to secure the clips.
And Also, Do not forget to add the sim tray.
