DIY: Samsung Galaxy S3 Screen Replacement

I’ve seen so many Samsung Galaxy devices with cracked screens and I don’t know if it’s only a problem with Samsung, but whenever I’ve seen someone drop their phone without an S3 case, the screen immediately gets some cracks. The problem is that it’s not something that the average user can fix on his/her own and most users are likely to go get it repaired after paying a lot of money. And you can’t expect people to stop using their phone or testing it out with S3 accessories and other cool things.

If you’re looking for a way to replace the cracked glass on your own and at a much cheaper price, continue reading to find out how you can do it on your own. This guide is to fix cracked screen of Samsung Galaxy S3. Your device’s actual display must be working if you want to replace the front glass.


What You Need

As we’re not replacing the actual display, the replacement tools shouldn’t cost you a lot and this package along with all the relevant tools is for $17.99 on Amazon. You can also look for the replacement tools at a local store if you don’t want to buy it on Amazon.

Aside from that, you’ll also need a heat gun or hair dryer in order to heat up the glue on the cracked screen. Lastly, some patience will be needed if you want to replace the screen successfully.


How To Replace the Cracked Screen

Only attempt to replace the screen if you know what you’re doing and if you’ve used some hardware tools before. I’ll only show you the steps that you’ll need to perform and you should only do it at your own responsibility.

Step 1

Open the back cover of your phone, remove the battery and slide out the SIM and micro SD cards. This is probably the easiest step in this entire guide.

Step 2

Remove the screws using the star screwdriver that is in the screen replacement package. After removing the screws on the back, the back frame should come off.

Step 3

In order to take out the motherboard, remove the screw on the motherboard. Removing the motherboard is optional, but you can take it out to ensure it doesn’t get damaged due to the heat from the heat gun or hair dryer. If you don’t want to remove the motherboard, proceed to Step 7.

Step 7

Use a heat gun or a hair dryer around all the borders and corners of the screen. This might take about 2 to 5 minutes. If you’re using a hair dryer, this might take a lot of time. Don’t overheat the phone as this might damage the digitizer. We’re only heating up the glue behind the glass so that it comes off easily.

Step 8

This will be the hardest step. Using the guitar picks and plastic separation tools in the glass replacement package, start removing the glass. Start from the top border of the screen and work your way towards the bottom. Make sure that some of the picks or opening tools are in place behind the glass while you’re working on another border to avoid the borders getting glued again.

This will take a lot of patience and hard work. Don’t rush into it because you might damage the actual display of the screen. Be extra careful while removing the glass from the bottom of the screen because the on screen buttons are also glued there. You might need to use the heat gun again during the whole process and at the bottom so that the buttons can get detached from the glass.
