Step-by-step instructions

NOTE: This is a general set of instructions. Specific steps might vary depending on your model. Watch the videos below for visual guides to replacing your Samsung Galaxy power button and flex cable.

If you have a Samsung Galaxy S6 or newer model, start at STEP 1. If you have a Galaxy S5 or older model, skip to STEP 3. Always power off your phone, remove the SIM card tray and any microSD cards before you begin.

STEP 1: Use the hair dryer to heat the edges of the rear glass and soften the underlying adhesive.

STEP 2: Place the suction cup on the lower part of the rear glass and gently lift until you can insert a guitar pick in the bottom seam.

STEP 3: Use a spudger and/or guitar picks to pry around the side seam until you can remove the rear cover. If you have an older model, remove the battery now.

STEP 4: Remove screws from the midframe and use the spudger to gently disconnect any visible cables so you can remove the midframe.

STEP 5: Use the spudger to disconnect all cables from the motherboard, then gently remove the motherboard. BE CAREFUL, because the motherboard might have a connecting cable underneath that must be removed before you lift it completely out of the frame.

STEP 6: Use the spudger to remove the battery (if not removed in STEP 3).

STEP 7: Use the tweezers to remove the power button/flex cable assembly.

STEP 8: Separate the power button from the flex cable.

STEP 9: Replace the power button and/or flex cable, then follow these instructions in reverse order to reassemble your Samsung Galaxy phone.
