Let’s get right to the point: The Samsung Galaxy S4 screen repair has arrived at JCD Repair. Like the Galaxy S3 repair we’re already doing, this repair will replace a cracked front glass in a short amount of time for a great price.
Ever since we launched our Galaxy S3 service, we have been getting a lot of requests for glass repairs on this newer model. The problem has been the Galaxy S4 was just different enough from the GS3 that we had to develop a few new techniques to get the repair right.
Like the GS3, the Samsung Galaxy S4 has an advanced LCD technology. The LCD is what displays the phone’s picture. For the GS3 and GS4, it also senses your finger touches (called the digitizer). This means the front glass for both models is, well, just a piece of glass. No wires connected to it. No electronics on it. Just painted glass glued onto the LCD.
And it’s this glue that turned out to be the big difference between the two repairs. The adhesive Samsung used on the GS4 is a lot “stickier”. It’s slightly harder to get the glass off the LCD but, more importantly, even after you get the glass removed, you still have a significant portion of the adhesive stuck to the LCD. And it is stuck like concrete.
Fortunately, using a combination of plastic razor blades and precisely controlled heat, we have been able to develop a process for removing that adhesive.
Once that adhesive is gone, the repair is extremely similar to our standard Galaxy S3 repair:
- The glass is removed (that’s the big difference).
- Some protective shielding is put in place to keep the new adhesive from getting into the guts of the phone.
- We apply a layer of liquid, ultra violet, optically-clear glue.
- Slowly lower a brand new, OEM piece of glass on to the LCD.
- Place the entire assembly in a vacuum chamber to remove all air bubbles from under the glass and properly set the new glass.
- Place the screen under a UV light to cure the optically-clear glue.
After that last step, the phone’s screen will look and work like it just rolled out of the factory.
Note: While we’ve spent 2 months developing all the tools and skills to do this repair, we haven’t yet trained all of our staff company wide on this repair. That is happening as I write this. However, we didn’t want to make everyone who needs this repair wait. So, at the moment, we are only offering this repair through the mail. That means, for the short-term future, if you have a cracked Samsung Galaxy S4, you will have to mail it in to us to get the repair completed.
