How to troubleshooting Galaxy A6 2018 that keeps freezing and lagging

Before you start troubleshooting your device software, check and ensure that your phone has sufficient memory or storage space. Lags and freezes are among the common symptoms of insufficient or low memory issues in various devices, so make sure it’s not what’s causing you this trouble. If necessary, you can manage your phone’s internal memory and free up some space by deleting old and unnecessary contents including messages, photos, videos and apps that are no longer useful. You can also transfer your other important files to your external storage media or a computer. If the memory is okay but your phone is still lagging or freezing, then go ahead and troubleshoot to rule software errors and glitches out from the underlying cause. Here are your options:

First solution: Perform a soft reset/device restart.

Performing a soft reset can potentially fix the problem if it only occurs among other minor glitches on the phone software or apps. Doing so will clear and refresh all apps and phone system and likewise free up some space of your phone’s internal storage.  

  1. To soft reset or restart your Galaxy A6 2018, press the Power button until the menu appears and then tap the option to Power Off. After 30 seconds, you can press the Power button again until the device restarts.
  2. Alternatively, you can just press and hold the Power button and the Volume Down button on the side until the phone restarts.

Both these methods won’t affect any data stored on the internal memory, so you won’t lose any critical information in the process.

Second solution: Boot into safe mode and diagnose apps.

All third-party apps and services are temporarily disabled while in safe mode, therefore it will be easier for you to determine if the problem is inflicted by a third-party app or not. Here’s how to enable safe mode on your Galaxy A6 2018 smartphone:

  1. Press and hold the Power button until the phone vibrates, and the Samsung logo appears then release the Power button.
  2. With the Samsung Galaxy logo still on screen, press the Volume Down button.
  3. Keep holding the Volume Down button until Safe Mode appears in the lower-left corner of the Home screen or lock screen.
  4. You can release the Volume button by then.

Use your device as you normally do while in safe mode and see if it still freezes or lags. If it doesn’t, then any of your downloaded apps or contents is the culprit. In that case, you can try uninstalling individual apps from the most recent download you have and then test your device afterwards to find out if the problem is fixed. If the problem continues after removing an app, continue deleting the next suspect app then test your device.

If your phone still lags and freezes while in safe mode, then it likely needs service.

Third solution: Wipe cache partition on your phone.

Wiping the cache partition clears temporary files and data from the phone’s cache partition (system cache). System cache files can cause similar issues especially when they get corrupted. Wiping cache partition is also recommended if your device started to act up after installing a new software or Android update. This won’t erase any data and personal information saved on the internal memory of your phone. Here’s how it’s done:

  1. With your device powered off, press and hold the Power and Volume Up buttons simultaneously for a few seconds.
  2. Release the buttons when the Android screen appears and the phone loads in Recovery mode.
  3. Press the Volume Down button several times to scroll to and highlight Wipe Cache Partition from the given options then press the Power button to confirm selection.
  4. Wait until the phone has finished wiping cache from the system partition. You will then see the Reboot system now option highlighted.
  5. To restart your device, press the Power button.

Wait until your phone is finished restarting and then try to see if the problem is gone. If it persists, then continue to the next workaround.

Fourth solution: Update your phone software to the latest version available.

New software updates also offer security enhancements or fix patches to address existing bugs that inflicted different types of software problems in Android devices. Should the problem you’re dealing with is caused by some bugs and malware, then updating your Galaxy A6 2018 software to the latest version available is likely the key to fixing it.

To check for software (Android) update available for your device, head over to Settings-> About device -> Software update -> Update now or Settings -> Software update -> Download updates manually.

To download and install software update via over-the-air, your phone must be connected to the wireless Internet and has enough battery life and memory space. If all the requirements are met, then you can start downloading the update. Just follow the onscreen instructions to finish the entire process.

After the new update is installed, reboot your phone to apply the recent changes properly.

Fifth solution: Perform a master reset/factory data reset.

This is often considered as last resort if all else failed to fix the problem. There might be some more intricate software errors and glitches that caused your phone to freeze or lag persistently. In that case, a full system restore would be necessary to wipe everything from the phone system including bugs and malware. This however will delete all your personal information, customized settings, downloaded apps, and other critical data from the internal memory. Should you wish to proceed, back up all your important files and then follow these steps:

  1. Tap Settings from the Main Menu.
  2. Scroll to and tap General Management.
  3. Tap Reset.
  4. Select Factory data reset from the given options.
  5. Tap Reset to continue.
  6. Tap Delete All to confirm deletion of all your data.

If your phone screen is not responsive, then you will need to perform a master reset or factory data reset using the hardware keys. Here’s how it’s done:

  1. With your device powered off, press and hold the Power and Volume Up buttons simultaneously for a few seconds.
  2. Release the buttons when the Android screen appears and the phone loads in Recovery mode.
  3. Press the Volume Down button to highlight Wipe data/Factory reset option.
  4. Then press the Power button to confirm selection.
  5. When the factory data reset is finished, the Reboot System Now option is highlighted. Press the Power button to confirm and reboot your device to apply the recent changes and refresh the operating system.

Everything should be working fine after the factory reset unless your device is damaged.

Other options

If your Samsung Galaxy A6 2018 smartphone continues to freeze and lag after exhausting all prior methods and applicable solutions, then you should already consider opting for service this time. There might be some hardware components that are damaged and caused your device to slow down. In this case, physical repair would be necessary. You then can take your device to a Samsung service center in your place for proper hardware assessment and/or repair.
