The power button on your Galaxy S6 Active can stop working or only work intermittently over time. The buttons on your smartphone consist of two contact points that activate their assigned function once they've come in contact with each other. Sometimes those contact points become worn and don't always recognize each other when they're being touched. Buttons also have tiny bumpers that are made to push the button back up after they've been released by your finger. Those bumpers can also become worn in, causing your power button to become stuck or sunken in. Whatever may be causing the issue with the power button on your Galaxy S6 Active, iParamedics will get it working again with our power button replacement service.
