One of the issues that you might experience with your Samsung Galaxy Z flip 4 is when it seems to be quite slow. Opening apps or even navigating its user interface is a slow experience. This lagging issue can be annoying as you don’t usually expect this from a premium Android phone.

Here’s what you need to do to fix the Galaxy Z Flip 4 slow performance issue.

Solution 1: Soft reset your Galaxy Z Flip 4

The first thing you should do when your Samsung phone lags is a soft reset.

A soft reset or restart will basically close all running apps and processes. Your Samsung device RAM will also be cleared of temporary data allowing it to run smoothly.

This procedure will reboot the operating system of the Samsung Galaxy Z Flip 4 and reload all of its services. Your personal data, files, and apps will remain unchanged

Soft reset Galaxy Z Flip 4

  • Turn off the Galaxy z Flip 4 by pressing and holding the Bixby button and the volume down button on the side of the device.

  • Choose Power off again. The phone will turn off.
  • Wait for a few seconds.
  • Press and hold the Bixby button on the side of the device to turn on the Samsung phone.

Try checking if the slow issue persists.

Solution 2: Close third-party applications running on your Samsung Galaxy Z Flip 4

If there are many apps running in the background, then this might be what’s causing your phone to run slow. These apps use up system RAM and when your phone runs out of RAM it’s going to slow down.

Consider closing any running third party application or try to disable any third-party launcher app that you might be using. If you have any anti-virus apps installed, then you should close this as well.

End background process

  • Press the Application key found at the bottom of your Samsung phone.
  • To end one running application, slide your finger upwards on the required application.
  • To end all running applications, press Close all.

Try checking if the Samsung phone still lags.

Solution 3: Start the Samsung Galaxy Z Flip 4 in Safe Mode

Starting Samsung phones in Safe Mode is a good way to check if an app you downloaded is causing the problem. When your phone runs in this mode only the pre-installed apps will be allowed to run making troubleshooting app related issues easy to do.

  • Continue to hold the Volume down key until the device finishes restarting.
  • When Safe mode appears in the bottom left corner of the screen, release the Volume down key.

If you are not experiencing any slow or sluggish performance issues in this mode, then the problem is most likely caused by an app you downloaded. Find out what app this is and uninstall it. The likely suspect is the most recently installed app before the issue slow occurred.

After uninstalling the app, you can exit from safe mode.

Exit Safe Mode

  • Press and hold the Side key.
  • Tap Restart > Restart.
  • The device will restart in standard mode and you can resume normal use.
