This is a representative image of a damaged S4, your device may vary in extent.

• Some images may be cropped due to orientation issues.

Remove the back plate using your fingernail or a spudger.

Remove the battery with your fingernail or spudger.

• If a SIM card is present, press and release to eject.

Be cautious when using a heatgun on this device, as excessive heat can damage the digitizer and cause discoloration.

• Preheat the glass for 3-5 minutes, ideally 4 minutes, at the lowest setting of your heatgun.
• Avoid using a hair drier, as it does not produce sufficient heat.
• Monitor the device closely; if discoloration occurs, immediately turn off the heat gun to prevent damage.

The goal of this procedure is to soften the adhesive holding the glass to the screen assembly.

Start at the top and gently pry the glass away from the phone's edges using a metal spudger.

Be cautious not to damage any components.

• Work your way around the edges with plastic picks.
• Take your time to avoid shattering the glass.

• If your screen is heavily cracked, apply several layers of packing tape and proceed carefully to prevent further damage.

• Wear safety glasses if you anticipate handling broken glass.

• Use a plastic razor blade or a guitar pick for intricate cleanup, as they won't scratch the digitizer.

Apply reheating cycles as needed, gradually increasing the temperature until the glass separates easily.

• If the glass resists removal, increase the heat and repeat the process.

Be cautious when removing the glass near the two touch keys at the bottom as they can be damaged easily.

• The touch keys are attached to the glass and must be removed before lifting off the glass.
• With the glass removed, you will see the digitizer with adhesive residue remaining.

Wipe the digitizer with lint-free wipes or a clean microfiber towel.

• Lens cleaner can be used on a microfiber cloth for added cleaning power.

Glue residue may remain, but this is typically not noticeable when the screen is turned on.

For deeper cleaning or stubborn glue residue, use acetone-free nail polish remover, which will evaporate quickly and leave a nearly flawless finish.

Apply new adhesive to edges of phone.

If original adhesive is missing, use 3M 2mm strips.

Remove protective covering from top of new adhesive.

Avoid touching the undersurface or getting any debris on it.

Prepare your new glass by removing any protective covering from one side only, leaving the under surface intact for now.

If you accidentally touch the underside or get it dirty, clean it off immediately before proceeding.

Prevent LOCA glue from contacting earpiece speaker and front-facing camera lens.

• Apply a thin layer of LOCA glue to the phone's screen using a video tutorial as reference.
• Remove top plastic cover on new glass before attaching it to the phone.

Reinsert the battery and SIM card.

Replace the back plate and power on your phone.
