Galaxy A53 - Replacing the screen

Use our checklist to test the basic functions of your Galaxy A53 5G before repairing. This way you can check afterwards if your repair was successful.

1. Press and hold the side and volume down button simultaneously for a few seconds.
2. Tap on Power off in the displayed menu.

1. Heat the edge of the back cover by running the hot air device evenly over it.

As an alternative to the suction cup, we can recommend the iSclack, which requires less force to lift up the back cover.

The iFlex can be inserted particularly well between the back cover and the screen unit due to its sharp edges.

1. Attach a suction cup to the lower edge of the back cover and pull it upwards to create a narrow gap.
2. At the same time, insert a flat tool into the gap between the back cover and the screen unit.

In order to prevent the glue of the back cover from bonding again, we recommend sliding flat plastic picks under the back cover at regular intervals.

To avoid damaging the camera module, you should not insert your tool too far. At this point, the hard plastic pick is therefore particularly suitable.

1. Drive your tool completely around the edge of the back cover to loosen it piece by piece.
2. Put the detached back cover aside.

• 8 × 3.8 mm Phillips

We recommend using a screw storage, such as our magnetic pad, to keep all disassembled parts and screws safe and organized.

1. Remove the eight Phillips screws from the board cover and place them in the screw storage.

A small arrow as well as a notch on the component show you where you can best place your tool.

We recommend testing the replacement screen and other basic functions at this point. Again, use our checklist for this and the internal Samsung test menu, which you call up via the code *#0*#.
If something doesn't work properly during testing, double-check that everything is installed and attached correctly.

1. Switch on your Galaxy again.
2. Test the touch function by dragging an app across the screen.

If the adhesive frame is still in good condition, you do not need to install a new one. However, if it has defects or no longer sticks properly, we recommend that you use a new adhesive frame.

1. Align the new adhesive frame with the back cover. The cutouts in the film will help you.
2. Peel off the carrier film from the bottom of the adhesive frame and press it onto the edge of the back cover.
3. Now carefully peel off the remaining protective films from the top of the adhesive frame.

We recommend that you run hot air over the edge of the back cover again, so that the glue bonds properly. You can also weigh down your device with books for a few minutes.

1. Close your Galaxy A53 after the repair by pressing the back cover back onto the screen unit.
