SAMSUNG PHONE • DAILYTECH.ID - Restarting a Samsung phone can be done using the power button, button combinations, the Settings menu, or a force restart if the device is frozen. This guide explains all restart methods, including restarting without a power button, handling black screens, entering Safe Mode, and model-specific Samsung Galaxy instructions for the S, A, and Z series.
In the world of modern smartphones, a simple restart is often the “magic fix” for a multitude of sins. Whether your device is experiencing slight lag, app crashes, connectivity glitches, or the dreaded frozen screen, a reboot refreshes the system memory and clears out temporary bugs without affecting your personal data.
For Samsung Galaxy users, the process has changed slightly over the years. With the introduction of the “Side Key” (which replaced the dedicated Power Button) and the removal of the Home Button, knowing exactly which combination to press is essential. This guide covers every conceivable way to restart your Samsung phone, from the standard software methods to hardware-level overrides for unresponsive devices.
How to Restart a Samsung Phone Normally
The standard restart is the safest way to reboot your phone. It allows the operating system (One UI) to close all active processes and save system data before powering down.
- Swipe down from the top of your screen to open the Quick Settings panel.
- Tap the Power icon located in the top-right corner (next to the Settings gear).
- Select Restart, then tap it again to confirm.
When to use this: Use this method for routine maintenance or when you notice minor performance drops. On newer Samsung models, pressing and holding the Side Key might trigger Bixby by default rather than the Power Menu, making the Quick Settings method the most reliable software route.
How to Restart a Samsung Phone Using Buttons
If you prefer using physical hardware or if your screen is partially unresponsive, the button method is your best bet.
The Side Key & Volume Down Method
On most modern Galaxy devices (S21, S22, S23, S24, and the A-series), the traditional “Power Button” is now a Side Key. To trigger the power menu:
- Press and hold the Side Key and the Volume Down button simultaneously for about 2–3 seconds.
- The Power Menu will appear on the screen.
- Tap Restart.
Reconfiguring the Side Key
If you hate that holding the Side Key opens Bixby, you can change it. Go to Settings > Advanced Features > Side Key and select “Power off menu” under “Press and hold.”
How to Restart a Samsung Phone Without the Power Button
Broken buttons shouldn’t prevent you from refreshing your device. There are several ways to trigger a reboot using only the software interface.
Method 1: The Settings Menu
If you can navigate the screen but your buttons are stuck:
- Open Settings.
- Search for “Restart” or go to General Management.
- Look for the Reset or Auto Restart options (Note: some versions only allow scheduling here, so the Quick Settings panel remains the primary software method).
Method 2: Accessibility Menu (Assistant Menu)
- Go to Settings > Accessibility > Interaction and dexterity.
- Turn on the Assistant Menu.
- A floating icon will appear. Tap it, select Power off menu, and choose Restart.
How to Force Restart a Frozen or Unresponsive Samsung Phone
When your screen is completely “frozen”—meaning it doesn’t respond to touch and the screen is stuck on an app—you need a hardware-level force restart.
- The Combination: Press and hold the Volume Down and Side Key/Power Button at the same time.
- The Timing: Do not let go when the power menu appears. Keep holding for 7 to 10 seconds.
- The Result: The screen will go black, and the Samsung logo will appear. This simulates a “battery pull,” cutting power momentarily to force the CPU to reboot.
How to Restart a Samsung Phone When the Screen Is Not Working
A “Black Screen of Death” occurs when the phone is powered on (you might feel vibrations or hear notifications) but the display remains dark.
- Perform the Force Restart (Volume Down + Side Key for 10 seconds).
- If the logo doesn’t appear, plug the phone into a charger for 15 minutes and try the combination again while it is plugged in.
- If you have a Samsung computer or tablet, try connecting the phone via USB. Sometimes the “handshake” between devices can wake the display driver.
How to Restart Samsung Phone in Safe Mode
Safe Mode is a diagnostic tool that starts the phone without any third-party apps running. It’s perfect for determining if a downloaded app is causing your phone to crash.
How to Enter Safe Mode:
- Open the Power Menu (Side Key + Volume Down).
- Long-press the “Power Off” icon on the screen.
- A “Safe Mode” icon will appear. Tap it to restart.
How to Exit Safe Mode:
Simply restart your phone normally. When it boots back up, it will be in the standard mode with all your apps restored.
How to Restart a Samsung Phone After a Software Update
After an Android or One UI update, your phone may feel sluggish or warm. This is because the system is re-indexing files in the background.
- Recommended Action: Perform a standard restart immediately after the update finishes.
- Post-Update Issues: If the phone is stuck on the “Optimizing Apps” screen for more than 30 minutes, perform a Force Restart to nudge the process forward.
How to Enable or Disable Auto Restart on Samsung Phone
Samsung phones include a feature called “Auto Restart at Set Times.” This keeps your phone fresh by rebooting it while you sleep.
- Go to Settings > Device Care.
- Tap Auto Optimization.
- Select Auto Restart.
- Toggle the switch to On and set your preferred schedule (e.g., 3:00 AM on Mondays).
