If you’ve been using your phone for a year or so, you might encounter problems with the power button. Not knowing how to turn your phone on or off can be frustrating when the power button is malfunctioning. This issue could be caused by physical damage or incorrect software settings. But there’s no need to worry because we’re here to help. Our guide will provide the necessary assistance to resolve any power button issues you may be experiencing with your Galaxy A02 / A02S.

Fix Samsung Galaxy A02 / A02S Power Button Not Working

The power button is a crucial feature of any smartphone, enabling users to perform various important tasks like locking/unlocking the phone and restarting it. If you’re experiencing issues with your power button not functioning, there’s no need to panic. There are a few solutions you can try to remedy the situation. Here are three solutions to consider if you’re experiencing problems with the power button on your Galaxy A02 / A02S.

Solution 1: Use Biometric Authentication to Unlock your Phone 

First and foremost, you need to unlock your phone. This can be easy if you have set up biometric authentication on your phone. You can use the face unlock or the fingerprint to unlock your phone.

However, if you don’t have any biometrics set up, you can use the screen lock to unlock your phone. You can ask a friend or family member to call you, which will turn your phone on. If this is not possible, plug your phone into the charger, and it should turn on. Once you have unlocked your phone, you can proceed with the other solutions.

Solution 2: Enable Double Tap to Lock 

If the power key doesn’t do anything, you must look for different ways to lock and unlock your phone. In this case, you can enable the double tap to lock feature. Here’s what you need to do:

1. Open the Settings app on your Galaxy A02 / A02S.
2. Tap on Advanced features.
3. Then, tap on Motions and gestures.
4. Turn on the toggle next to the Double tap to turn off the screen.
5. Once you have turned this on, you can lock your screen by simply tapping space on your home screen twice.

Solution 3: Remap the Power Button to a Different Key

Double tapping to lock and unlock may work in the short run, but what will you do if your phone freezes and you can’t go to the home screen? To avoid such situations, you must remap one of the Volume keys to act as the power key for your Galaxy A02 / A02S. You must use a third-party app such as Key Mapper to achieve this.

Solution 4: Power Off Using the Volume Keys and Power Button

Sometimes, the power button may be fully functional, but the problem is that when you long-press it, it activates Bixby instead of showing the power off menu. In this case, you can power off your phone by pressing the Volume Down and Power buttons for at least 7 seconds. 

If you don’t want to deal with Bixby on your power button, you can turn it off from the settings. Here’s how: 

1. Open the Settings app.
2. Tap on Advanced features.
3. Then, tap on the “Side key.”
4. Under the Press and Hold section, select “Power off menu.”

Solution 5: Schedule a Restart 

If you don’t mind your phone powering off at a scheduled time, you can set it to restart at specific times. This means that your device will restart automatically on the prescribed day of the week and time without you having to press the power button. Here’s how to use this feature:

1. Open the Settings app.
2. Tap on General Management.
3. Tap on Reset.
4. Ensure the toggle next to Auto restart at set times is turned on.
5. Tap on an Auto restart at set times to configure when your phone restarts.

Solution 6: Power Off from the Quick Settings Panel

The Quick Settings panel has a tiny power icon that lets you power off your phone without pressing the power button.

Simply scroll down from the top and drag the Quick Settings panel down. You should see a small power icon at the top of the panel. Tap on it and select Power off. Tap on Power off again to finally turn your device off.

Solution 7: Replace the Power Button 

It should be noted that some of the above solutions may work only in the short run and not in the long run. If your power button is still not working, you must replace it at a Samsung service centre.
