First solution: Soft reset or device restart.

Lags and freezes may also appear among other random issues when the phone system is going rogue. Often times, random system errors or glitches can be remedied by a simple restart or performing a soft reset on the phone. So you should try this first. Here’s how to restart or soft reset a Galaxy A8 2018 smartphone:

  1. Press and hold the Power button for a few seconds until the power options show up.
  2. Select Power off then tap OK. Your phone then turns off.
  3. After 30 seconds, press and hold the Power button again until your phone boots up.

Alternatively, you can do a force restart if your phone screen is frozen or not responding to touches. Just follow these steps:

  1. Press and hold the Volume down button first and don’t let it go.
  2. Now, press and hold the Power button while holding down the volume down button.
  3. Keep both buttons held down together for 10 seconds or until the device power cycles.

Both these restart methods effectively clears minor software errors without affecting any saved data on your phone.

Second solution: Clear cache and data on your phone system.

Temporary data or cache files that are corrupted can also trigger similar issues to occur on your phone. If the problem occurs only on a certain app, then clearing the app cache and data will likely fix it. Otherwise, wiping cache partition on the phone is necessary. Here’s what you should do next, to clear cache files and temporary data from your Galaxy A8 2018 including those that are causing system errors:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  3. When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds, then ‘No command’ 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 to highlight “Yes” and press the Power key to confirm.
  7. When the wipe cache partition is complete, “Reboot system now” is highlighted.
  8. Press the Power key to restart the device.

Allow your phone to finish booting up and then try to use it to find out if it is already working properly. Otherwise, continue to troubleshoot.

Third solution: Boot in safe mode and diagnose apps.

To rule out errant third-party apps from the triggers, enable safe mode on your Galaxy A8 2018 smartphone. Doing so will temporarily disable third-party apps and services, allowing you to diagnose apps carefully. Simply follow these steps:

  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. You can release the Volume button by then.

Use your device as you usually do while in safe mode to test its performance. If it doesn’t lag or freeze while running in safe mode, then it means that a third-party app is the trigger. Try to think of which app you’ve downloaded recently that caused your device to misbehave. It’s likely the one you’ve downloaded prior to the onset of the symptoms. You can delete individual apps starting from the most recently installed then test to see how your phone works removing each application.

Fourth solution: Update phone software to the latest Android version.

Performance problems in mobile devices that are attributed to malware and software bugs are usually addressed by an update. Software updates contain fix patches or security enhancements to get rid of any existing bugs. Hence, keeping your device software up-to-date is recommended. To check for new update on your Galaxy A8 2018, follow these steps:

  1. Swipe up from the bottom of the Home screen.
  2. Tap Settings.
  3. Scroll to and select Software Update.
  4. Select the option to Download updates manually.

Your device must be connected to the Internet to complete the update download and installation process. Ample power and memory space are also among the requisites to consider. If updating wirelessly is not possible, then you can update your phone on your computer through Samsung Kies instead.

Fifth solution: Reset and restore your phone to factory defaults/factory reset.

Your last ditch solution would be a factory reset or master reset. Symptoms like this usually persist if they’re attributed to some tough bugs that caused complex system errors on the device. But also note that this reset wipes everything from your phone including all your apps, data, and customized settings on the phone. Should you wish to proceed, back up all your critical data beforehand. Then proceed with these steps whenever you’re all set:

  1. Press and hold the Power button to turn off your phone.
  2. While it’s off, press and hold the Volume Up and Power buttons simultaneously for a few seconds.
  3. Release both buttons when the Samsung logo appears.
  4. Tap on the screen if the Android Robot image with No Command shows up. Doing so will launch the Android Recovery screen.
  5. Press the Volume Down key on your phone several times to highlight “wipe data/factory reset” from the given options.
  6. Then press the Power button to confirm selection.
  7. Press the Volume Down key again to highlight/select Yes — delete all user data then press the Power button once to confirm.
  8. The Reboot system now option will then become highlighted. At this point, just press the Power button to trigger your phone to reboot.

If possible, you can also do a factory reset using the Settings menu on your Galaxy A8 2018 smartphone. Here’s how it’s done:

  1. Open the Menu to access apps.
  2. Tap Settings.
  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.

Set up your device as new when the reset is finished and everything should be working fine and smoothly by now. Otherwise, your device needs service.

Other options

Performing the prior methods is usually enough to get your device back to its normal performance if software issues are the underlying cause. Otherwise, service would be necessary. Persistent freezing and lagging symptoms on your Galaxy A8 2018 smartphone are often inflicted by hardware damage and in that case, your device needs service. You can take your device to a nearby Samsung service center in your place and have it diagnosed thoroughly by an authorized technician. This is a must-do if you happened to drop your phone or got it wet before the symptoms instigate.

Alternatively, you can contact your device carrier or Samsung Support for more help in performing more advanced troubleshooting procedures or any other applicable options.
