The Two 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. Samsung phones offer two restart methods: a soft restart (power off and back on) and a force restart (holding buttons to restart without powering down first). A soft restart is gentler and should be your first choice. A force restart is what you use when your phone is frozen and won't respond to normal commands.

Both methods take less than two minutes and won't erase your photos, messages, or any saved data. The difference is which one your phone will actually respond to in the moment.

Key Takeaways

  • A soft restart means powering your phone off completely, waiting a few seconds, then powering it back on—this is the gentler option and should be your first try.
  • A force restart uses button combinations to restart without powering down, and it works even when your phone is completely frozen or unresponsive.
  • The button combination for a force restart varies by Samsung model: older phones use Power + Volume Down, while newer Galaxy phones use Power + Volume Up.
  • After a restart, your phone will take 30 to 60 seconds to fully load before you can use it normally.
  • If your phone still freezes after a restart, the problem may be a specific app or a storage issue rather than a temporary glitch.

How to Do a Soft Restart

A soft restart is the standard way to turn your phone off and back on. Press and hold the Power button (usually on the right side of your phone) until a menu appears on your screen. This takes about 3 to 5 seconds. You will see options including "Power off" or "Shut down"—tap that option.

Wait 10 to 15 seconds after the phone powers down completely. This pause lets the phone's memory fully clear. Then press and hold the Power button again until you see the Samsung logo appear on the screen. Release the button and let the phone finish loading. You will see your lock screen within 30 to 60 seconds.

A soft restart is safe to do anytime and won't harm your phone or data. If your phone is responding to button presses at all, this is the method to use first.

How to Force Restart When Your Phone Is Frozen

A force restart works even when your phone won't respond to the Power button. The button combination depends on your Samsung model. For most newer Galaxy phones (Galaxy S10 and later), press and hold the Power button and Volume Up button at the same time. Keep holding both buttons for about 10 seconds, even if you see the power-off menu appear—ignore it and keep holding.

For older Samsung models (Galaxy S9 and earlier), press and hold the Power button and Volume Down button together instead. Again, hold for about 10 seconds. You will feel a vibration, and the Samsung logo will appear on the screen. Release both buttons when you see the logo.

If you are not sure which model you have, check your phone's settings: go to Settings, then About Phone, and look for the model number. You can also search "[your model number] force restart" online to confirm the right button combination before your phone freezes.

A force restart is completely safe—it does not erase data or damage your phone. It straightforward forces the system to shut down and restart when ready, bypassing any frozen interface.

What Happens During and After a Restart

When your phone restarts, it closes all running apps and clears the temporary files stored in RAM (random access memory). This is why a restart fixes most problems: apps that were using too much memory, background processes that were stuck, and minor software glitches all get wiped clean.

After you see the Samsung logo, your phone will show the lock screen within 30 to 60 seconds. However, the phone is still loading in the background—apps are starting up, notifications are syncing, and your home screen is rebuilding. Wait another 30 seconds before opening apps or doing heavy tasks. If you try to use your phone when ready, it may feel slow or unresponsive for a few more seconds.

You will not lose any photos, messages, contacts, or installed apps. A restart does not touch your stored data—it only clears temporary memory.

When a Restart Does Not Fix the Problem

If your phone still freezes or crashes after a restart, the problem is usually a specific app rather than a general system glitch. Try restarting in Safe Mode, which loads only the basic Samsung apps and disables all third-party apps you installed. Press and hold the Power button until the power menu appears, then press and hold "Power off" (not just tap it) until a Safe Mode option appears. Tap Safe Mode.

If your phone works normally in Safe Mode, one of your installed apps is causing the problem. Go to Settings, then Apps, and look for recently installed or frequently used apps. Uninstall the app you suspect, restart normally, and see if the freezing stops. If you cannot identify which app is the culprit, uninstall recent downloads one at a time and test after each one.

If your phone still freezes even in Safe Mode, the problem may be storage-related. Go to Settings, then Storage, and check how much space you have left. If you have less than 1 GB free, delete old photos, videos, or apps to free up space, then restart again. A phone running out of storage often behaves like it is frozen.

Restarting Without Losing Your Data

Both a soft restart and a force restart preserve all your data. Your photos, messages, contacts, calendar events, and installed apps remain exactly as they were. The only thing that changes is that all running apps close and temporary files clear.

However, if you are in the middle of typing a message or editing a document when you restart, that unsaved work will be lost. Close or save any open work before restarting if you can. If your phone is completely frozen and you cannot do this, the restart will interrupt whatever you were doing, but the app will straightforward close—your saved files and previous messages will still be there.

If you are concerned about losing data, you can back up your phone before restarting. Go to Settings, then Accounts and Backup, and tap Backup and Restore. However, a restart itself will not erase anything, so a backup is not necessary unless you are planning a factory reset (which is different from a restart).

Frequently Asked Questions

How often should I restart my Samsung phone?

Restart your phone when it is freezing, running slowly, or apps are crashing. You do not need to restart on a schedule. Some people restart once a week as routine maintenance, but it is not required. Restart whenever you notice a problem, and the phone should return to normal speed.

Will a restart delete my photos or messages?

No. A restart only clears temporary memory and closes running apps. All your photos, messages, contacts, and installed apps stay on your phone. The only data you might lose is unsaved work in an app you were actively using at the moment of restart.

What is the difference between a restart and a factory reset?

A restart closes all apps and clears temporary memory, but keeps all your data. A factory reset erases everything on your phone and returns it to like-new condition. A factory reset is a much bigger action and should only be done if you are selling the phone or have serious persistent problems. Always back up your data before a factory reset.

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

If your phone stays on the Samsung logo for more than 5 minutes, try a force restart again. If that does not work, your phone may have a software problem that requires recovery mode or professional service. Contact Samsung support or visit a carrier store for help.

Can I restart my phone while it is charging?

Yes, restarting while plugged in is fine. However, if your phone is very low on battery, charge it to at least 20 percent before restarting, just to be safe. A restart uses a small amount of power, and you want enough battery to complete the process.
