How to fix Galaxy Note10 lagging after Android 10 update

Some Galaxy Note10 and Note10+ users are reporting lagging or slow performance issues as their units are finally getting Android 10 update at around this time. If Android update history is to be considered, this issue is no longer new. Major software overhauls do not always go as planned in some cases. If you’re one of the unlucky few who encounters lag issue on your Note10 right now, don’t worry. This issue can easily be fixed. This article will show you how to get your unit back to its normal working state again.

Causes of Note10 lagging after Android 10 installation

Lag or slow performance is one of the hard issues in Android to fix because there are a lot of things that can cause it. Thankfully in this article, we have a specific situation wherein lagging appears on a Galaxy Note10 after an Android 10 update. This means that the most likely reason can be attributed to the general change in software environment.

In most cases, lag after an update is caused by a corrupted system cache. This is the first one that you want to address.

In other cases lag after an Android update can be attributed to other factors such as:


  • bad app
  • coding issue, or
  • some unknown software glitch.

Whatever the cause of your lag problem is, we’ll have that covered below.

Can lagging be fixed on your Note10 running Android 10?

Yes. Update issues is already an expected part of life among many Android users. When a new, “stable” release of Android is released, it’s not a perfect product.

Just like any software, it needs a lot of work even though developers have poured millions of hours on it ahead of time. Not all software problems can be anticipated ahead of time. The good thing is, developers will try their very best to eliminate most of the issues so only minor ones may be experienced by users once the product is released.

We’ll show you what to do if you encounter lag problem after an Android 10 update.

How to fix Galaxy Note10 lagging after Android 10 update

There are a number of potential solutions to fix lag Note10 lagging issue after an Android 10 update. Make sure to try each one before moving to another else.

Solution 1: Wipe cache partition

In some rare cases, a device may lag or appear to experience slow performance following an update. If your Note10 started lagging after Android 10 update, the first thing that you should check is to know if the cause of the problem is due to bad system cache.

This special cache is used by your device to load apps quickly and sometimes, it can get corrupted during or after an update. When this happens, the loading time for apps may appear abnormally long.

Other issues may also appear though there’s no diagnostic tool to pinpoint if a system cache issue is taking place. What you can do as a user is to clear the location where this cache is stored called cache partition.

How to refresh the system cache on Galaxy Note10

  1. Turn off the device. This is important as your device won’t boot to Recovery Mode when it’s on.
  2. Press and hold the Volume Up key and the Bixby / Power key.
  3. Once the Android Recovery screen comes up, release the buttons.
  4. Use the Volume Down button until you are highlighting ‘Wipe cache partition.’
  5. Press the Power button to select ‘Wipe cache partition.’
  6. Use Volume Down to highlight Yes.
  7. Press the Power button to confirm the action to clear the cache.
  8. Wait for a second as the system wipes the cache.
  9. Press the Power button again to reboot the device. This will return the device to the normal interface.
  10. That’s it!

Solution 2: Check for overheating

If you noticed that your Note10 has become uncomfortably warm to touch after updating, overheating may be to blame. Overheating is usually a sign of something deeper and rarely is the main cause for problems. It can be due to either a software bug, app glitch, or hardware malfunction.

If your Note10 was perfectly working fine before you installed Android 10 update, lag due overheating can be one of the signs that there’s a problem somewhere. It can be shaken off by clearing the cache, or a factory reset may be necessary.

If your Note10 is overheating at this point, what you can do is to continue with the rest of the suggestions in this post. If you’re not experiencing any overheating though, just skip this troubleshooting step.

Solution 3: Ensure apps are updated

When you update Android, it does not automatically mean that apps get updated too. You’ll have to see to it that apps are updated if you’re not positive. By default, your Note10 should automatically download updates for apps via Play Store but in case you want to manually check, you can do so easily.

Check for Play Store app updates:

  1. Open Play Store app.
  2. Tap More settings icon at the upper left (three-horizontal lines).
  3. Tap My apps & games.
  4. Tap Update or Update All.

If you are on Cellular Data connection, we suggest that you update via wifi only to avoid additional charges. Here’s how:

  1. Open Play Store app.
  2. Tap More settings icon at the upper left (three-horizontal lines).
  3. Tap Settings.
  4. Tap App download preference.
  5. Select Over wifi only (select Over any network if you don’t have wifi).
  6. Tap Done.

Make sure to also keep your apps updated all the time by enabling auto-update option.

  1. Tap Auto-update apps.
  2. Tap Over wifi only (select Over any network if you don’t have wifi).
  3. Tap Done.

How to update apps outside the Play Store

By default, you can’t readily install apps without going through the Play Store. In the Galaxy Note10, you can allow installation of third party apps by enabling a number of settings. The thing is, updating the apps you install outside the Play Store may not be straightforward, depending on how the apps you have are designed. Apps from reputable companies like Samsung makes it as hassle-free for the user as possible. For example, in order to update the default Samsung Messages app, which can’t be installed from the Play Store, the steps should be similar to these steps below:

  1. Open the Samsung Messages app.
  2. Tap More settings icon at the upper right (three dots).
  3. Select Settings.
  4. Tap About Messages.
  5. Tap Update button. If there’s no Update button, that means that the app is fully updated.
  6. Check for the problem.

To update your other Galaxy Note10 third party apps, there may be a totally different way to do them so be sure to contact the developer for guidance.

Solution 4: Check for bad app

Another possible reason why you may be having lag or slow performance problem is a bad third party app. Some apps may be poorly coded at the time when a new Android version arrives and this can cause problems. If you’ve already updated all apps in your inventory but your Note10 is  still lagging, you must consider restarting the phone to safe mode. In this mode, all third party apps are blocked (greyed out) so they can’t run. If there’s your Note10 works normally and it’s not laggy when on safe mode, a bad third party app must be behind the trouble.

To restart your Samsung Galaxy Note10 to safe mode

  1. With your device turned on, press and hold the Power button until the Power off menu appears then release.
  2. Touch and hold Power off until the Safe mode prompt appears then release.
  3. To confirm, tap Safe mode.
  4. The process may take up to 30 seconds to complete.
  5. Upon reboot, “Safe mode” should appear in the lower-left of the home screen.
  6. Check for the problem.

Safe Mode may be a useful trick in checking for a problem but it won’t pinpoint the exact app. In order to identify which of your apps may be behind the problem, you’ll have to do a process of elimination. Here’s what you need to do exactly:

  1. Boot Galaxy Note10 to safe mode.
  2. Check for the problem.
  3. If the issue returns or once you’ve confirmed that a third party app is to blame, you can start uninstalling apps one by one. You’ll need to do spend some time doing this if you have plenty of apps installed. We suggest that you begin with the most recent ones you added.
  4. It’s important that you only uninstall a single app at a time. After removing an app, restart the phone to normal mode and check for the problem again.

If your Galaxy Note10 is still problematic, repeat steps 1-4 until the rogue app has been identified.

Solution 5: Factory reset

If your Note10 is still lagging after Android 10 update, that means that the problem requires a more drastic solution. You’ll need to wipe the device with a factory reset. Also known as master reset, this solution is often effective in restoring the normal working order of Android after a major software upgrade. Below are the two ways to factory reset your Note10.

Method 1: How to hard reset on Samsung Galaxy Note10 via Settings Menu

This is the easiest way to wipe your Galaxy Note10. All you have to do is to go under Settings menu and follow the steps below. We recommend this method if you have no trouble going under Settings.

  1. Create a backup of your personal data and remove your Google account.
  2. Open Settings app.
  3. Scroll to and tap General management.
  4. Tap Reset.
  5. Select Factory data reset from the given options.
  6. Read the information then tap Reset to continue.
  7. Tap Delete All to confirm action.

Method 2: How to hard reset on Samsung Galaxy Note10 using hardware buttons

If your case is that the phone is not booting up, or it boots but Settings menu is inaccessible, this method can be helpful. First, you need to boot the device to Recovery Mode. Once you successfully access Recovery, that’s the time that you begin proper master reset procedure. It may take some tries for you before you can access Recovery so be patient and simply try again.

  1. If possible, create a backup of your personal data ahead of time. If your problem prevents you from doing that, then simply skip this step.
  2. Also, you want to make sure that you remove your Google account. If your problem prevents you from doing that, then simply skip this step.
  3. Turn off the device. This is important. If you can’t turn it off, you’ll never be able to boot to Recovery Mode. If you are not able to shut the device off regularly via the Power button, wait until the phone’s battery is drained. Then, charge the phone for 30 minutes before booting to Recovery Mode.
  4. Press and hold the Volume Up key and the Bixby / Power key.
  5. When the green Android logo displays, release both keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  6. The Recovery screen menu will now appear. When you see this, release the buttons.
  7. Use the Volume Down button until you are highlighting ‘Wipe data/factory reset.’
  8. Press the Power button to select ‘Wipe data/factory reset.’
  9. Use Volume Down to highlight Yes.
  10. Press the Power button to confirm the action to clear your phone data.
