How to troubleshoot Galaxy S9 that’s running very slowly?

In this troubleshooting guide, I will only tell you what to do because the S9 is not a new phone anymore and you may already know most of the procedure. This will be quick and to the point and with that being said, here are the things you can do about this problem…

Observe your phone in Safe Mode

This must be the first thing you must do to know if the sluggishness you feel with your device is caused by third-party elements such as apps and services. By doing this, you’re temporarily disabling all downloaded apps and leave pre-installed ones running. So it follows that if the problem is caused by a third-party app, your phone should run normally and fast while in Safe Mode. If that’s the case, the next thing you have to do is find out which app causes the problem and uninstall it.

However, if the phone is still slow while in this mode, then it’s possible that the problem is with the firmware. Move to the next solution.

Free up some storage space

If you haven’t checked the remaining internal storage of your device, then now is the perfect time to do it because having storage space less than 1 Gigabyte will also cause sluggishness and other performance issues. Remember, that everything that runs on your device needs some storage space as files are created especially huge apps and games. You may need to move some of your files and data to an SD card or computer. But if there’s enough storage left in your device, then try the next procedure.

Wipe Cache Partition

Corrupt or obsolete system cache may also cause the phone to have a very poor performance. Such is the case with some of our readers but the thing is, you would only know if it’s really the case after wiping the cache partition. By doing this, you’re deleting old system cache and replace it with a new one.

It is advisable to perform this procedure especially after a firmware update as the cache is needed to be replaced more often. To do this, you will have to run your phone in recovery mode and wipe the cache partition from there. After doing this and your Galaxy S9 is still slow, then move on to the next solution.

Backup your important files and data and reset your phone

After everything failed to fix the problem, then you have no other choice but to reset your phone. It will bring the device back to its default settings and configuration. However, you have to make a backup of your important files and data as they will be deleted during the reset and you may not be able to retrieve them after that.

I suggest you perform the master reset through the recovery mode as it’s more effective than the reset through the Settings menu.

I hope that we’ve been able to help you fix the problem with your Galaxy S9 through this article. Again, if you need our help, feel free to contact us anytime.
