and remove the front-facing camera from the S4.
How to remove Display Assembly (LCD & Touch Screen)
The S4 SGH-i337 Display Assembly (LCD & Touch Screen) is fused together and cannot be separated. The display assembly is secured to the frame/front housing of the smartphone with a good amount of adhesive; it will require heat, and patience, to separate.
This procedure is recommended only on smartphones with a display assembly that is ALREADY DAMAGED. Use a heat gun or blow drier to heat the adhesive securing the display assembly to the smartphone’s frame/front-housing.
To separate the Samsung display assembly from the rame/front housing, utilize one of the screwdrivers or he plastic opening tool and through the front-facing camera hole, while securely gripping the sides of the S4’s frame/front housing, carefully push the damaged display assembly away from the S4’s frame/front housing.

You can now use the nylon spudger or plastic opening tool to continue working around the Galaxy S4 display assembly slowly separating it from the frame/front housing. Be mindful of the home button assembly toward the bottom of the Samsung smartphone.
With the S4 display assembly seperated from the frame/front housing, you can utilize the flat end of the spudger to remove the home button assembly.
