Start by turning off your Samsung Galaxy A14 to prevent any electrical damage. Press and hold the power button, then select 'Power off'. Wait until the device is completely powered down before proceeding.

Using a plastic opening tool, gently pry around the edges of the back cover to release its clips. Be careful not to apply too much force to avoid damaging the cover or internal components.

Locate the battery connector and use a spudger to carefully disconnect it. This ensures no power is flowing through the device while you work on it.

Use a heat gun or hair dryer to gently heat the edges of the screen. This softens the adhesive, making it easier to remove the old screen. Be careful not to overheat the device.

Place a suction cup near the edge of the screen and gently pull to create a small gap. Insert a plastic opening tool into the gap and work your way around the device to detach the screen from the frame. Use caution to avoid damaging the internal components.

Remove any remaining adhesive from the frame using isopropyl alcohol and a lint-free cloth. Ensure the surface is clean and dry before applying new adhesive.

Apply adhesive strips or double-sided tape around the edges of the frame. Align the new screen carefully and press it firmly into place to ensure a secure fit.

Reconnect the battery connector using a spudger, ensuring it is securely attached. This will restore power to your device.

Align the back cover with the device and press it firmly along the edges to snap it back into place. Ensure all clips are securely fastened.

Power on the device and test the new screen for responsiveness and display quality. Ensure everything is functioning correctly before concluding the repair.
