    • Small Flat Head Screwdriver
    • Plastic Pry Tools

    Samsung Galaxy S4 Repair Guide:


    • First you will want to make sure your device is fully powered off before you begin.
    • Next remove the back battery cover as well as the battery, sim-card, and Micro SD.
    • Then taking a Small Phillips Screwdriver #00 remove the nine (9) screws circled in the figure below

    See figure below for screw locations:

    Next you will need to take your plastic pry tool or nylon spudger and insert it between the seam of the back housing to be able to remove it from the device.

    See figure below for reference:

    • Now you will see another reference figure below showing another small phillips screw that will need to be removed which is circled in red in the upper right side of the device.
    • You will also see five (5) pop-connections and two (2) antenna cables that will need to be released in order to proceed with the dis-assembly.
    • With all of these steps done properly you will be able to remove the motherboard completely from the device.
    See figure below for reference:

    With the motherboard now removed you can proceed by removing the two (2) small phillips screws circled in red in the figure below and you will see more components and connections will are going to remove and release from the device.
    See figure below for reference:

    You will see we have broke down the next 8 steps in the figure below.


    • 5.1: Here you can take a small flat head screwdriver or pry tool and remove the small black cover
    • 5.2: Use a pry tool or your fingers to remove the headphone jack
    • 5.3: Using a pry tool remove the ear speaker and attached sensors (held down with a little adhesive)
    • 5.4: Pry and lift out the front camera
    • 5.5: Here we used a small flat head screwdriver to pry up and remove the vibration motor from the housing (held down with a little adhesive)
    • 5.6: Remove the silver cover on the USB port using a pry tool or your flat head screwdriver
    • 5.7: You will need to release the pop connector that is located on the long flex cable shown about in the mid-left section of the device. From here you can then begin peeling the flex cable and assembly from the housing and the bottom of the device. The bottom circuit board is held down with some adhesive so you will want to be very careful not to damage this flex cable assembly.
    • 5.8: Lastly you can remove the lower flex assembly and dock port completely from the housing.

    See figure below for reference:

    • To complete the dis-assembly of your Galaxy S4 you will now need to flip the screen assembly over and apply heat to the outer edges of the screen to warm and loosen the adhesive holding the LCD & Touch screen to the frame.
    • Using your heat source on a medium setting heat the outer edges of the screen hovering roughly 3-4 inches away from the screen.
    • Once the adhesive has been properly warmed and loosened you can now take your small plastic pry tool and insert it between the seam of the touch screen and front housing.
    • You will get to a point to where you will want to insert a tool like the nylon spudger and get behind the LCD screen to break up and release the adhesive holding the LCD to the mid-frame.
    • Once you have working the edges releasing all of the adhesive you will be able to completely remove the screen assembly from the housing.

    See figure below for reference:

    When installing a new screen assembly we highly suggest using fresh adhesive to secure your new screen assembly to the mid-frame and front housing. You will need to clean up any glass shards or other debris to ensure a proper and snug fit before you put your device back together.
