What to do if your Galaxy S10 is running slow

There’s no direct way to identify what is causing a top phone like the Galaxy S10 to run slow. If you have not done anything different and the problem happened all of a sudden, you need to do a number of troubleshooting steps to know where it’s coming from.

Close all apps

Too many apps running actively and in the background may cause slow performance. Although Android is designed to automatically manage RAM efficiently without user input, it does not happen at all times. If left running for a long time, it may be unable to work properly as well as developers hope. From time to time, you still need to close apps in order to clear its memory. If you’ve been experiencing slow performance issue for some time now, closing apps as a troubleshooting step is not a bad idea.

If you don’t want to manually close all apps, you can try to selectively do so by going after big, resource-demanding apps first like games or social media apps. To close an app on the Galaxy S10:

 

1. Tap the Recent Apps key, which is left of the home button on your screen (shown above)
2. Scroll up or down to see what’s running and open
3. Swipe from the left or right to close apps
4. Swipe it off the screen to close it
5. This will clear the app

If you want to just simply close all apps:

1. Tap the Recent Apps key, which is left of the home button on your screen (shown above)
2. Scroll up or down to see what’s running and open
3. Select Close All button at the bottom of the screen.

Forced reboot

Should closing your apps fail to fix the problem, the next thing to do is to restart the device. Instead of the usual restart though, it’s better if you can simulate the effects of a soft reset or a “battery pull” procedure. In older devices, this is done by simply removing the battery to restart the phone. Since it’s borderline impossible to do that on the S10, what you can do is to its equivalent. Here’s how it’s done:

1. Press and hold the Power + Volume Down buttons for approximately 10 seconds or until the device power cycles. Allow several seconds for the Maintenance Boot Mode screen to appear.
2. From the Maintenance Boot Mode screen, select Normal Boot. You can use the volume buttons to cycle through the available options and the lower left button (below the volume buttons) to select. Wait for up to 90 seconds for the reset to complete.

Wipe cache partition

Another possible reason why your Galaxy S10 may be running slow is the fact that its cache partition may be corrupted or outdated. Android keeps a cache called system cache in order to load apps faster. This cache is stored in the cache partition, a separate area in your phone’s internal storage specifically designed to hold the cache. Sometimes, updates or app installation may corrupt the cache, which in turn, may result to problems for Android. One such problems may be slow performance. If you noticed that it’s taking a long time to load apps, or if there’s significant sluggishness when doing simple tasks on your device, it’s probably due to a system cache issue. To keep the cache in top shape, we suggest that you try wiping the cache partition. Follow these steps:

1. Turn off the device.
2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
3. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
4. Press the Volume down key several times to highlight ‘wipe cache partition’.
5. Press Power button to select.
6. Press the Volume down key until ‘yes’ is highlighted and press the Power button.
7. When the wipe cache partition is complete, “Reboot system now” is highlighted.
8. Press the Power key to restart the device.

Install updates

Some forms of slow performance problems on Android are due to poor coding. This means that there’s nothing much a user can do about them except to wait for coding changes via updates. If your S10 is running slow due to an issue with the software, it’s important that you keep the device updated. Keep in mind that there’s no obvious indicator whether a problem is due to poor coding or not. So, it’s a good idea to keep the software and apps updated all the time.

Check for bad apps

Another possible reason for your problem can be due to a bad third party app. To check if that’s the case, try running the device on safe mode. Doing so will tell stop all third party apps from running. So, if the device works significantly faster on safe mode, you can bet there’s a problem with one of your apps. To isolate which of your apps may be causing it, follow these steps to load the phone to safe mode:

1. Turn the device off.
2. Press and hold the Power key past the model name screen.
3. When “SAMSUNG” appears on the screen, release the Power key.
4. Immediately after releasing the Power key, press and hold the Volume down key.
5. Continue to hold the Volume down key until the device finishes restarting.
6. Safe mode will display in the bottom left corner of the screen.
7. Release the Volume down key when you see Safe Mode.
8. Once on safe mode, try to charge the phone for at least 30 minutes and see what happens.

If you’ve confirmed that there’s a bad app in the system, the next thing to do is delete the most recent app you installed. If you can’t remember which app was installed recently, or if uninstalling it won’t work, use the process of elimination to identify it. This is how it’s done:

1. Boot to safe mode.
2. Check for the problem.
3. Once you’ve confirmed that a third party app is to blame, you can start uninstalling apps individually. We suggest that you begin with the most recent ones you added.
4. After you uninstall an app, restart the phone to normal mode and check for the problem.
5. If your S10 is still problematic, repeat steps 1-4.

Check for overheating

In some cases, the main reason for slow performance issue is overheating. This can occur if there’s an app issue, software glitch, or hardware malfunction. If you noticed that your device has gone slow and become too warm to touch when you use it, it’s likely overheating. By design, the Galaxy S10 is supposed to keep the system slower or shut down the system if internal temperature becomes too high.

In most cases, overheating can also just be an indicator of a deeper problem. If your S10 keeps overheating even when you’re not using it to run big apps like games, there may be a more serious trouble underlying it. You must do a factory reset to check if it can be fixed on your end or not.

Factory reset

Speaking of factory reset, this should be the final troubleshooting step that you can do. By doing this, you are returning all software settings to their defaults, which makes the software environment more stable. Factory state software is thoroughly tested and has higher stability than newly released Android versions. Here’s how to factory reset your device:

1. Back up data on the internal memory. If you have signed into a Google account on the device, you have activated Anti-theft and will need your Google credentials to finish the Master reset.
2. Turn off the device.
3. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
4. When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
5. Press the Volume down key several times to highlight “wipe data / factory reset.
6. Press Power button to select.
7. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
8. Press Power button to select and start the master reset.
9. When the master reset is complete, “Reboot system now” is highlighted.
10. Press the Power key to restart the device.

Get Samsung support

If the problem won’t go away even if the software has already been reset, that means the cause is beyond your ability to fix. It can be an unknown coding issue or there’s a hardware problem that needs to addressed. We suggest that you visit your local Samsung Service Center or bring the device to your carrier. It must be examined thoroughly so a technician will need to have it physically.
