Samsung Galaxy S4 Screen Repair Tutorial

 

This Tutorial has been divided into 3 parts for better understanding. Parts 1 and 2 have been presented with the help of videos whereas part 3 has been presented with the help of images

 

1.    Phone Disassembly (To Separate Screen)

2.    Separating Broken Glass

3.    Bonding New Glass

 

Part 1: Phone Disassembly (To Separate the Cracked Screen)

 

  

Part 2: Separating the Broken Glass 

Keep 2 simple rules in your mind at this stage 

·          Be patient   

·          No use of power - Just Technique 

  

Precaution !

While inserting the card between the glass and the screen, be careful and don’t damage the ribbon pointed by red arrow in the image below. This flex ribbon controls the touch function of lcd.

 

Some Tips:  

·         In this video metal tool has been used initially to insert the play card. You can use metal blade for this purpose provided in the kit. 

·         Use play cards that are strong enough to bear resistance. 

·         You need hot air gun (preferably) or Hair Dryer for this job. 

·         It’s a good idea to use some scotch tape to prevent the glass from shattering during repairs.

  

Digital thermo-meter (used in this video) is NOT necessary. You can use finger tips of your left hand while holding the hot air gun or hair dryer in your right hand. Heat up the screen to a level where you could not place your finger tips on it for more than 1-2 seconds. If you feel that it is still hard to insert the card between the broken glass and screen, give some more heat. Avoid using power here and don’t heat it up to its boiling point. The broken glass would start coming off. Completely remove it and then clean the screen with the help of the glue remover provided. Now we will bond new glass on the screen.

  

Part 3: Bonding New Glass

 

To get the best possible display results, UV glue is used to bond the new glass on the screen. The UV glue is applied in a particular pattern on the screen. There are a number of different patterns however we have shown the best one below, based on our experience. Here don't forget to remove bubbles or dust particles from the glue or screen, if any. See these images;

  

  

Drying the UV Glue

  

Our UV glue can be dried in sunlight. Approximate time is 45 minutes. Alternatively UV torch can be used .With UV Light, Drying time of the UV glue is around 10-15 minutes.
