How to Replace the Galaxy S7 Screen, Charging Port and Home Button

As we all know, for Samsung Galaxy S and Galaxy Note series phones, the front frame is strongly glued to the LCD assembly and hardly being removed for individual users or unexperienced technicians. For those who want to make the replacement work easier and less risky, a Galaxy S7 LCD and digitizer with frame would be the best screen replacement if unfortunately your Galaxy S7 screen was broken. However, if theGalaxy S7 charging port or home button was damaged and had to be replaced, then the disassembly of Galaxy S7 front housing is a must. Here we’re going to walk you through how to replace a LCD assembly, charger port or home button by disassembling the Galaxy S7 LCD and digitizer assembly with front housing.

Tools Needed:

• Plain Cards

• Gloves
• Spudger
• Screwdriver

For the Galaxy S7 teardown process, please move to our post of How to Tear Down the Galaxy S7 for Screen Replacement. Please note that you run your own risk to disassemble the device and the warranty will be voided.

1. Galaxy S7 Screen Replacement.

Heat up around the edges of Galaxy S7 LCD assembly back and forth to soften the front housing adhesive underneath. Pay your patience, the Galaxy S7 LCD assembly and frame are bonded by extremely sticky waterproof adhesive so as to make it IP68 protected. The waterproofness of Galaxy S7 will lost once the screen was replaced unless you apply the adhesive as sealed as the original manufacturer made, which is almost impossible to realize.

Wear a pair of gloves to avoid your hands being hurt by the hot display. Carefully insert the tip of a plain card into the gap between LCD assembly and frame, run it back and forth to weaken the adhesive.

You can also heat up and insert a plain card on the opposite side to release the nicely sticky adhesive.

Now the Galaxy S7 LCD assembly and frame are successfully separated. Looks like it's so easy, isn't it? I'm afraid not, tedious maybe more appropriate. Anyway, get your patience and chariness prepared.

2. Galaxy S7 Charging Port Replacement

After the Galaxy S7 front housing was released from the LCD and digitizer, undo the 2 screws holding the Galaxy S7 charger port assembly in place.

Peel off the two navigator stickers from the opposite side of charging port assembly.

Pry up to release the microphone.

Now the Galaxy S7 charging port with flex cable ribbon was disassembled.

3. Galaxy S7 Home Button Replacement

Like the disassembly of charging port assembly, peel off the sticky waterproof adhesive around the home button.

Pry up the home button and flex cable ribbon.

Now the Galaxy S7 home button with flex cable ribbon was removed.
