Galaxy S10 - Replacing the screen

1. Keep the Power button pressed until the option "Switch off" is shown on the display.
2. Confirm the "Switch off" with your finger and wait until the screen is black.

The back cover is firmly glued. To loosen it, you have to heat it up first.

1. First turn your Galaxy S10 with the display side down.

To avoid scratches on the display screen, you should place your device on a clean, soft surface.

1. Use a hot air device, such as a heat gun or a regular hairdryer, and drive it evenly over the edge of the back cover from the outside.

As a rule of thumb, heat the edge of the back cover only to the point where you can still touch it without burning your fingers.

Once opened, your Galaxy S10 is no longer waterproof, and the warranty for protection against dust and splashing water expires.The backcover is made of glass and can break very easily. Therefore, be extra careful and take your time.

1. Place a suction cup at the bottom of the backcover and pull it upwards to create a narrow gap between the backcover and the housing frame.
2. Insert a flat, sturdy tool into the created gap. Try to enlarge the gap by pushing the backcover with the tool additionally upwards. We use the iFlex for this.

Take care not to insert your tool too far, so that you do not damage anything under the backcover.

1. Use a flat plastic tool to go around the edge of the housing piece by piece. We use the iPlastix for this.

The iFlex is made of thin, sturdy metal, making it easier to get into the gap between the back cover and the case frame. However, the sharp edges of the iFlex make it easier to scratch the frame. We therefore recommend that you use the iFlex only initially and continue with iPlastix, which is made of flexible plastic, as soon as possible.

1. To prevent the adhesive from rebonding in the areas that have already been loosened, you should always heat the edge of the display and leave individual, flat picks in the device frame.
2. Remove the detached back cover and put it aside.

• 8 × 3,9 mm Phillips

Under the back cover there is a plastic cover which is connected to the coil for contactless charging and the NFC antenna.The cover is hooked onto the upper edge of the display unit, the coil is slightly glued.

1. First unscrew the Phillips screws that hold the plastic cover in place.
2. Slide a flat tool under the glued coil to carefully loosen it. We use a steel spatula for this purpose.
3. Then lever the plastic cover with a lever tool from the upper edge of the display unit. For this purpose we use a plastic spudger.
4. Now you can remove the cover including the coil and the NFC antenna.

• Battery connector

Always lever from the side where there are no small components on the mainboard. This way you avoid potential damage to capacitors or ICs.

1. Carefully disconnect the battery contact from the mainboard with the spudger.

The battery is heavily stuck. The adhesive is only on the edge of the battery, not in the middle.

Never heat the battery directly and bend it as little as possible when removing it to avoid damaging it.

1. Heat the battery with the hot air tool from below over the display.
2. Using a flat, stable tool to carefully lever the battery on all sides out of its lead. We recommend using a battery spudger or an iSesamo.
3. Take the loosened battery out of your Galaxy S10 and put it aside.

• Camera connector

To prevent damaging PCB components you should always lever from the side where there are none.

1. Seperate the connector of the front camera from the mainboard with a spudger.
2. Then take the detached camera out of its lead with tweezers.

• 7 × 3,9 mm Phillips

1. Start by unscrewing the Phillips screws that secure the speaker.
2. Then lever the speaker out of the display unit using a spudger or tweezers.

The opening where you can place the tool is marked with a small triangle.

• 3 × 3,7 mm Phillips
• Display connector
• Headphone connector

1. First, carefully remove both the display connector and the headphone jack from the mainboard using a spudger.
2. Then remove the three Phillips screws that secure the board to the display unit.

There is a small plastic pin in the opening of the SIM tray. Make sure that it does not fall out when pulling out the SIM tray.

1. Pull out the SIM tray. Use a pointed object or a special SIM tool to press into the small opening next to the SIM tray.
2. Now you can carefully lever out the mainboard with a spudger and put it aside.

1. Use a steel spatula to gently lever the headphone jack out of the display unit.

If your replacement display already has an earcup installed, you can skip this step.

The earpiece is slightly glued to the inside of the display unit.

1. Loosen the earpiece by carefully sliding a steel spatula under it and then using tweezers to remove it.

If your replacement display already contains a vibration motor, you can skip this step.

The vibration motor of the Galaxy S10 is glued to the inside of the Galaxy S10.

Do not use levers on the golden contacts of the vibration motor, as bending the contacts can affect the functionality of the motor.

1. Loosen the motor by carefully inserting tweezers between motor and display unit.

1. Now take the new display and compare it with the old one. If necessary you have to take over seals or covers.
2. Pull the protective films off the adhesive surfaces.

1. Place the vibration motor in the small, round recess on the inside of the new display unit.
2. Then press the motor firmly with your fingers so that the adhesive can bond.

1. Put the earpiece back into its lead in the display unit.
2. Press it lightly so that the glue adheres better.

If there is an adhesive surface for the earpiece in the new display unit, first remove any old adhesive residue before inserting it.

Before reinserting the mainboard, bend all connectors to the side in order not to trap flex cables.

1. Take the mainboard and carefully put it back into the display unit of your Galaxy S10.
2. Place the mainboard on the lower edge of the display unit and press the charger socket back into its opening.
3. Then press the mainboard down so that it is firmly seated.
4. Insert the headphone jack into its opening in the lower part of the board and press it slightly until it locks into place.
5. Now slide the SIM tray back into the frame of the display unit.

If it does not slide in easily, check the position of the mainboard again.

1. Fix the mainboard with the 3 Phillips screws and finally attach all connectors on the board.

Make sure that it is hooked onto the lower edge of the display unit.

1. Tighten the speaker with the 7 Phillips screws.

• Camera connector

1. Place the front camera back in its lead at the top of the display unit.
2. Press down the camera and then its connector.

Make sure that the camera lens is dust-free and that all protective films are removed from the display unit.

If the adhesive frame on the inside of the display unit is no longer intact, you must remove it so that the battery is flush with the unit. In this case, attach adhesive strips to the bottom of the battery. Attach them in such a way that the adhesive does not come into contact with the black surface of the inside of the display unit.

1. Place the battery back into its guide in the display unit.
2. Press it firmly so that the adhesive can bond better.

• Battery connector

1. Now connect the battery connector on the mainboard by gently pressing it until it clicks into place.

2. Then press the cover firmly with your fingers until it gently snaps into place.
3. Fix the plastic cover with the 8 Phillips screws.

Test the functionality of your device before you fasten the backcover again. In particular, test the functions of the component you have replaced.

1. Turn your device on and test it with Samsung's integrated test mode.
2. Use the following key combination: *#0*#
3. Follow the instructions in the test menu and test e.g. the display, cameras and sensors.

If the adhesive frame at the edge of your back cover is no longer intact, you must carefully remove the adhesive residue and attach a new adhesive frame.
A back cover with an intact adhesive frame can be reattached directly.

1. Put the back cover back in its original position.
2. Then press it down over the entire surface so that the adhesive can bond well again.

To make the glue stick even better, you can also heat the edge of your Galaxy S10 with hot air and weigh it down with a few books.
