How to Repair a Samsung Galaxy S3 Screen

The touch-interface of the Samsung Galaxy S3 mobile phone consists of a glass face, digitiser and AMOLED screen. It is not uncommon for Samsung Galaxy S3 users to deal with a cracked glass face or broken screen. Because the glass is not fused to the screen, it is possible that a user may only need to replace the glass. If the screen is also damaged, it will be apparent when the screen is on. Accidental damage is not covered by warranty, but the company provides the service for a fee. The warranty is void if the device owner or a third party performs repairs. Owners who cannot repair their own device can contact a local repair provider or mail their device to a provider.
 

Required Tools

Repairs should be performed on an even, hard surface free of synthetic fibers to prevent electro-static damage. A grounding mat is not necessary for either of these repairs.
Replacement glass is often sold with a toolkit of guitar pick pry tools, spudger, suction cup, and micro screwdriver #00. In addition to the replacement parts, a hair dryer or heat gun is required and a small Xacto knife can aid in adhesive removal. Optional tools like gloves, a surface thermometer, windex, and microfiber cloth can assist the repair.
 

Replacing Cracked Glass

  1. Remove the rear cover, battery, SIM, and microSD card with a plastic pry tool.

  2. The screen itself is not fused with the glass, but attached to the frame around the edges. If the glass is severely cracked, placing a masking tape or a screen protector on it will prevent shards from damaging the screen. A hair dryer or heat gun heats the adhesive. Temperatures above 180 degrees may damage the cpu, so a surface thermometer is useful to guard against damage. Gloves are worn to protect the hands.

  3. Once the adhesive is heated, the pry tools are inserted in the space between the frame and glass. The adhesive resolidifies easily, so the ideal method is working from top to bottom and inserting four or more pry tools in the gaps. Special care must be paid to the bottom edge as menu and return button cables connect to the glass.

  4. Once the glass is removed, the top headset speaker grill is retained and the menu button is untouched.

  5. The remaining adhesive is removed with a small Xacto knife or a microfiber cloth treated with windex or isopropyl alcohol. Excess adhesive can cause dust to get trapped between the glass and the screen.

  6. A clean microfiber cloth removes the remaining dust from the screen.

  7. 3mm or smaller double-sided tape is applied along the edges of the frame.

  8. The protective film layer is removed from both sides of the new glass, and the headset grill is placed in the new screen. The glass is placed manually or by attaching a small suction cup to the middle of the face.
     

Replacing the Glass, Digitiser and Screen

The procedure is more complicated than replacing the glass because removal and re-assembly of components is required.

  1. The back cover is removed with a pry tool.

  2. Before proceeding, the new screen can be tested by removing the battery, disconnecting the screen flex cable from the top right, attaching the new screen’s cable, replacing the battery and powering the device.

  3. Most of the components are removed to prevent heat damage and provide access to the rear of the screen. The battery, micro SDcard, and SIM can be removed by hand. The device contains two protective panels secured by eight micro screws, and the bottom is removed first. Using a plastic pry tool or anti-static spudger, the flex cable for the headset is disconnected and the top panel removed. The screw at the bottom of the motherboard and the attached flex cables are removed, and the motherboard is lifted from the frame by gripping the edges. A user may opt to remove other components, such as the antenna, camera, power light and speaker.

  4. The screen is heated with a blow dryer or heat gun. Since the glass and screen are separate, it is recommend to remove the glass before attempting to force the screen loose.

  5. Force may be applied to the rear of the screen through the holes in the frame to dislodge the screen once the glass is removed.

  6. All adhesives and shards are scraped or lightly treated with a windex-coated microfiber cloth. If any residue is left, dust may gather in the camera and the screen may not sit evenly.

  7. The home button can be replaced if desired.

  8. The layer of protective film and adhesive backing are removed from the new screen. The connector cable is gently bent to a right angle and inserted through the frame. The new screen is attached to the frame and all the components are replaced.
