The three ways to restart a Samsung phone

A restart clears your phone's temporary memory and stops all running apps, which fixes most freezing, lag, and app crashes without erasing your data. Samsung phones offer three restart methods: the soft restart (power button only), the forced restart (power and volume buttons together), and the settings menu. Which one you use depends on whether your phone is responding to touch.

The soft restart is the gentlest option and works when your phone is still responsive. The forced restart is what you need when your phone is frozen or won't respond to taps. The settings menu restart is the slowest but the most straightforward if you have time and your phone is working normally.

Key Takeaways

  • A soft restart uses only the power button and takes about 30 seconds; use this first if your phone is responding.
  • A forced restart holds the power button and volume down button together for 10 to 20 seconds and works even when your phone is frozen.
  • The settings menu restart (Power Off, then Power On) is the slowest method but works on any Samsung phone that responds to touch.
  • After any restart, your apps and files remain on your phone — a restart does not erase anything.
  • If your phone restarts but the same problem returns within hours, a factory reset or a visit to a Samsung service center may be necessary.

Soft restart: power button only

Press and hold the power button on the right side of your phone for 10 seconds. Your phone will show a power menu with options like Power Off, Restart, and Emergency Mode. Tap Restart. Your phone will turn off and back on within 30 seconds.

Use this method when your phone is still responding to touch but is slow, freezing, or an app has crashed. This is the safest restart because it gives your phone time to close apps and services properly. Most Samsung phones recover from minor glitches after a soft restart.

Forced restart: power and volume buttons together

Press and hold the power button and the volume down button at the same time. Keep holding both buttons for 10 to 20 seconds, even if you see the Samsung logo appear. Your phone will vibrate, the screen will go black, and then it will restart. Release the buttons after the vibration.

Use this method when your phone is completely frozen, won't respond to taps, or won't turn off using the power button alone. The forced restart bypasses the normal shutdown process and forces your phone to restart when ready. This does not erase your data — it straightforward cuts power and restarts the system.

The exact button combination varies slightly by Samsung model. On some older models, you may need to hold power and volume up instead. If power and volume down does not work after 20 seconds, try power and volume up, or check your phone's manual for the correct combination.

Settings menu restart: the slowest but most controlled method

Open Settings, scroll down to General Management, and tap Restart. Your phone will show a confirmation message. Tap Restart again. Your phone will turn off and back on within one minute.

This method works only when your phone is responsive enough to open the Settings app. It is the most controlled restart because your phone has time to close all apps and services before shutting down. Use this method when you have time and your phone is working well enough to navigate menus.

If you cannot find Restart in General Management, look for it under Settings > System > Restart, or straightforward hold the power button and tap Restart from the power menu instead.

What happens during a restart

When your phone restarts, it closes all running apps, clears temporary files from memory, and reloads the operating system. This process takes 30 seconds to two minutes depending on your phone model and how many apps you have installed. Your phone may show the Samsung logo or a loading animation during this time.

After the restart completes, your phone returns to the lock screen. All your photos, messages, contacts, and installed apps remain on your phone — a restart does not erase anything. Your settings and passwords also stay the same.

When to restart versus when to seek help

Restart your phone if it is slow, an app keeps crashing, the screen is frozen, or you have not restarted in more than a week. A restart fixes most temporary problems caused by apps using too much memory or the system getting bogged down.

If your phone restarts but the same problem returns within a few hours, or if your phone will not turn back on after a restart, the issue may be deeper. Try restarting one more time, then check if a software update is available in Settings > About Phone > Software Update. If the problem persists after an update, contact Samsung support or visit a service center.

Frequently Asked Questions

Will restarting my phone erase my photos or messages?

No. A restart only clears temporary memory and reloads the operating system. All your photos, messages, contacts, apps, and personal files stay on your phone. If you want to erase everything, you would need to do a factory reset, which is a different process.

How often should I restart my Samsung phone?

Restarting once a week or whenever you notice slowness is normal. Some people restart daily as routine maintenance. There is no harm in restarting frequently — it does not wear out your phone or drain your battery faster.

What if my phone will not turn back on after I restart it?

Let your phone sit for five minutes without touching it. Then plug it into a charger for 15 minutes — the battery may have drained during the restart. If the screen remains black after charging, try a forced restart again by holding power and volume down for 20 seconds. If it still will not turn on, contact Samsung support.

Is a forced restart the same as a factory reset?

No. A forced restart clears temporary memory and reloads the operating system but keeps all your data. A factory reset erases everything on your phone and returns it to the state it was in when you first bought it. A forced restart is safe to do anytime; a factory reset should only be done if you are sure you want to erase everything.

Why does my phone keep freezing even after I restart it?

Repeated freezing after a restart usually means an app is causing the problem, your storage is almost full, or your phone needs a software update. Check Settings > Storage to see how much space is left. If you are below 1 GB free, delete old photos or apps. If storage is fine, check for a software update in Settings > About Phone > Software Update.
