The Three Ways to Restart a Samsung Phone

A reboot clears your phone's temporary memory and stops all running apps, which fixes most freezing, lag, and app crashes. Samsung phones offer three restart methods: a soft reboot (the safest, everyday choice), a forced restart (when your phone is completely frozen), and a factory reset (which erases everything and should only be used as a last resort). Most of the time, a soft reboot solves the problem in under a minute.

The method you use depends on whether your phone is responding to touch. If your screen works and apps open, use the soft reboot. If your phone is frozen solid and won't respond to any taps, use the forced restart. A factory reset is only necessary if your phone has a serious software problem that survives multiple reboots.

Key Takeaways

  • A soft reboot takes 30 seconds and works when your phone is responding normally—hold the power button, tap "Restart," and wait for the Samsung logo.
  • A forced restart works on a completely frozen phone by holding the power and volume down buttons together for 10 to 20 seconds until the screen goes black.
  • The method varies slightly between Samsung models with physical buttons and newer models with side buttons, but the principle is the same.
  • A factory reset erases all your data and should only be used if your phone has a serious problem that a soft or forced restart did not fix.

Soft Reboot: The Everyday Restart

Use a soft reboot when your phone is working but slow, laggy, or running an app that keeps crashing. This method is safe and does not erase any of your data.

Press and hold the power button on the right side of your phone (or the side button, depending on your model) for about 3 seconds. A menu will appear with options including "Power off," "Restart," and "Emergency mode." Tap "Restart." Your phone will go black, the Samsung logo will appear, and your phone will turn back on. This takes about 30 to 60 seconds total.

Once your phone finishes restarting and you see your lock screen, wait another 10 to 15 seconds before opening apps. Your phone is still loading in the background during this time. If the problem was a single frozen app or temporary slowness, the soft reboot will have fixed it.

Forced Restart: When Your Phone Is Frozen

Use a forced restart when your phone will not respond to any taps, swipes, or button presses. This method forces your phone to shut down when ready without saving anything, but it does not erase your data.

The button combination depends on your Samsung model. On most Samsung phones with a physical home button (Galaxy S10 and older), hold down the power button and volume down button at the same time for 10 to 20 seconds. Keep holding even if you see a "Power off" menu—ignore it and keep pressing. Your screen will go black, the Samsung logo will appear, and your phone will restart.

On newer Samsung phones without a home button (Galaxy S20 and newer), the process is the same: hold the power button and volume down button together for 10 to 20 seconds. The screen will go black and the Samsung logo will appear. Do not release the buttons until you see the logo. Your phone will then restart normally, which takes 30 to 90 seconds.

After your phone restarts, it may take a few minutes to fully load all your apps and settings. This is normal. If your phone freezes again within a few hours, the problem may be a specific app or a deeper software issue, and you should consider a factory reset or contacting Samsung support.

Factory Reset: Complete Data Wipe

A factory reset erases all your photos, messages, apps, and settings and returns your phone to the state it was in when you first bought it. Only use this method if a soft reboot and forced restart did not fix your problem, or if you are selling or giving away your phone.

Before you factory reset, back up your data. Open Settings and tap "Accounts and backup" (or "Cloud and accounts" on older models), then tap "Samsung Cloud" or "Google Account." Tap "Back up" and wait for the process to finish. This saves your photos, contacts, messages, and app data to the cloud so you can restore them later.

Once your data is backed up, open Settings and scroll down to "General management." Tap "Reset" and then "Factory data reset." Your phone will ask you to confirm. Tap "Reset" again. Your phone will restart and erase everything, which takes 5 to 15 minutes. Do not turn off your phone during this process.

When your phone finishes, you will see the setup screen as if it were brand new. Sign in with your Samsung or Google account, and your backed-up data will restore automatically. This process takes another 10 to 30 minutes depending on how much data you have.

What to Do If Your Phone Keeps Freezing After a Reboot

If your phone freezes again within a few hours of a soft or forced restart, the problem is likely a specific app, not your phone's core software. Open Settings, tap "Apps," and look for any app you installed just before the freezing started. Tap the app name and select "Uninstall." Restart your phone and see if the freezing stops.

If you do not remember which app caused the problem, restart your phone in Safe Mode, which disables all third-party apps. Press and hold the power button, then press and hold "Power off" on the menu until a "Safe Mode" option appears. Tap it. Your phone will restart with only Samsung's built-in apps running. If your phone does not freeze in Safe Mode, one of your downloaded apps is the culprit. Restart normally and uninstall apps one at a time until the freezing stops.

If your phone freezes even in Safe Mode, or if freezing continues after you uninstall the problem app, a factory reset is your next step. If freezing continues even after a factory reset, your phone may have a hardware problem, and you should contact Samsung support or visit a Samsung service center.

Reboot Timing and What to Expect

A soft reboot takes 30 to 60 seconds from the moment you tap "Restart" until your phone is ready to use. A forced restart takes 10 to 20 seconds of button-holding, then 30 to 90 seconds for the phone to restart. A factory reset takes 5 to 15 minutes to erase everything, then another 10 to 30 minutes to set up and restore your data.

During any reboot, your phone will show the Samsung logo on a black screen. This is normal and means the process is working. Do not turn off your phone or remove the battery (if your model has a removable battery) during this time. If your phone is still showing the Samsung logo after 5 minutes, it may be stuck, and you should try a forced restart again.

After your phone restarts, it may run slowly for the first few minutes as it loads all your apps and settings. This is normal. Open your most-used apps to make sure they work, then give your phone 10 to 15 minutes of normal use before deciding whether the reboot fixed your problem.

Frequently Asked Questions

Will a reboot erase my photos and messages?

No. A soft reboot and forced restart do not erase any data. Only a factory reset erases everything, and you have to choose that option deliberately. If you are worried about losing data, back up your phone to Samsung Cloud or Google Drive before you do anything.

How often should I reboot my Samsung phone?

There is no set schedule. Reboot your phone when it is slow, freezing, or running an app that keeps crashing. Many people find that a weekly soft reboot keeps their phone running smoothly, but it is not required. If your phone works fine, you do not need to reboot it.

What is the difference between a soft reboot and a forced restart?

A soft reboot uses the power menu and lets your phone shut down normally. A forced restart forces the phone to shut down when ready by holding buttons. Use a soft reboot when your phone is responding, and a forced restart when your phone is frozen and will not respond to taps.

Can I undo a factory reset?

No, a factory reset is permanent and cannot be undone. That is why you must back up your data before you factory reset. If you backed up to Samsung Cloud or Google Drive, you can restore your data after the reset is complete by signing into your account during setup.

My phone is stuck on the Samsung logo after a forced restart. What do I try next?

Wait 5 minutes to make sure it is actually stuck and not just taking a long time. If the logo is still there after 5 minutes, try the forced restart again: hold power and volume down for 20 seconds, release, and wait. If that does not work, try a factory reset. If your phone is still stuck after a factory reset, contact Samsung support or visit a service center.
