To turn on a Samsung Galaxy phone, press and hold the Side key (or Power button) on the right edge of your device for a few seconds until you feel a vibration and see the Samsung logo. This simple action is the most reliable way to power up any Galaxy model, so you can turn on Samsung galaxy phone without needing any extra tools or apps.
How to turn on a Samsung Galaxy phone with the side button
On most modern Galaxy phones, the physical key that powers on the device is called the Side button, though older models may label it as the Power button. Samsung merged the traditional Power and Bixby keys into a single Side button on newer devices, but the function remains identical. To turn on your phone, locate this button on the right-hand side of the frame, it’s usually the only button on that side, positioned below the volume keys. Press and hold it for roughly two to three seconds. You’ll know it’s working when the screen lights up, the phone vibrates, and the Samsung logo appears; at that point, release the button and let the device finish booting.
If you’re using a Galaxy model with a removable battery (mostly older devices), the process is the same, but you may need to ensure the back cover is properly seated and the battery is inserted correctly before pressing the Side button. For all other models, the button is always accessible, and there’s no need to remove anything. Once the lock screen or home screen appears, your phone is fully on and ready to use.
What to do if your Samsung phone won’t turn on
If pressing and holding the Side button doesn’t produce any response, the most common culprit is a dead battery. A completely depleted battery may require several minutes of charging before the device can power on, and the charging indicator might not appear immediately, so don’t panic if the screen stays black for the first few minutes after plugging in. Use a Samsung-certified charger and cable that is compatible with your device, and plug it into a wall outlet rather than a computer or power bank for the fastest, most reliable charge. While waiting, check the charging port and cable for any debris, corrosion, or bent pins, as these can prevent proper charging; a gentle puff of air or a soft brush can clear out dust that might be blocking the connection.
If the phone still won’t turn on, the device may be frozen or unresponsive rather than out of battery. In that case, perform a forced restart by pressing and holding the Side key and the Volume Down key simultaneously for more than 7 seconds. This action will restart the phone without erasing data, so it’s safe to try even if you’re worried about losing anything. Release the buttons when the device vibrates and the Samsung logo appears, then let it boot normally. If the forced restart doesn’t work either, double-check that you’re using the correct charger and port, and try a different Samsung-certified cable if you have one on hand.
Setting up your phone for the first time
After the phone powers on for the first time, you will be guided through an initial setup process, including language selection, Wi-Fi connection, and Google/Samsung account sign-in. This step-by-step wizard appears only once, and it’s designed to get your device personalized and ready for daily use. You’ll be asked to choose a language, connect to a Wi‑Fi network, and then sign in with your Google account (for the Play Store) and your Samsung account (for Galaxy-specific features like Find My Mobile and Samsung Cloud). You can also choose to copy data from an old phone, set up biometric security like fingerprints or facial recognition, and customize a few display and sound preferences. The entire process usually takes less than 10 minutes, and you can skip most steps and finish them later from the Settings app if you’re in a hurry. Once you reach the home screen, your Galaxy phone is fully set up and ready to explore.
