Replacing the screen of your Galaxy S3 is very easy once you know how to do it, and the total cost for the equipment is just $15.99. With the kit, you get all the required tools needed to replace your screen, and you can also service your friends’ and neighbors’ S3s.
If you already have the kit, you can skip to the steps below. However, if you do not have the kit, you can purchase one for $15.99, which includes the replacement screen, on Amazon. Click here.
The only additional tool that doesn’t come with the kit is a heat gun, for which a hair dryer can also be used as an alternative during the process to melt the glue holding the broken screen to the phone body.
Steps to Replace the Galaxy S3 Screen.
- Remove the battery; this is important to prevent the battery from conducting additional heat from the heat gun or hair dryer, as it may result in a battery explosion.
2. As shown in the image above, use a heat gun or hair dryer to heat all four sides, so that the sticky glue holding the screen to the panels becomes soft. If you attempt to do this without heating, it may result in damaging internal circuits, as it will be difficult to pull the screen off. Once it has been heated, gently pry inside the glass of the screen for a few seconds to scoop it out. If the glass is broken in the corner, use the pry tool to remove fragments of broken glass.
3. Use the dryer or gun if the glass gets stuck; it is a good idea to start this procedure from one corner. As shown below, we started chipping the screen from the speaker side to its bottom.
4. After the screen is completely detached from the board, use a toothbrush or a towel cloth to remove the glue. Ensure that you clean the surface thoroughly.
5. Now you have two options: either use double-sided tape to hold the new screen, or you can also use small drops of super glue at the four corners. Before placing the new screen back, clean the mobile’s LCD once more to ensure there are no dust particles. Now, gently put the new screen back on and press it for a few minutes.
6. That’s done now; your phone is ready with the new screen.
