Samsung Galaxy S6 Edge Plus started running slow shortly after the Android Nougat update [Troubleshooting Guide]

Your Samsung Galaxy S6 Edge+ is one of the smartphones that pack impressive specs and is still considered to be one of the most powerful devices despite the fact that it was released a couple of years ago. It is still compatible with the latest version of Android and should have any issues running the operating system. But it seems like many S6 Edge+ owners are complaining about their devices that started running slow after the update.

We will look into this problem to see if it’s caused by the following…

  • some apps that constantly crash due to compatibility issues with the new firmware
  • an issue with the system that affects the overall performance of the phone
  • a bad update that might have some corrupt or missing files
  • corrupt system caches, files or data that the new firmware might still be using
  • a hardware problem that may not have been known if not because of the new update

In other words, we will look into each possibility and try to rule out each of them until we can certainly say what the problem with your phone really is. Once we know the problem, we can easily formulate a solution that might fix it and prevent it from happening again in the future. So, if you own a Galaxy S6 Edge+ that’s currently running slow for some reason, continue reading below as this post may be a great resource for you.

How to troubleshoot Galaxy S6 Edge Plus that started running slow after an update

Problem: “Hi! I’ve recently updated my Samsung Galaxy S6 Edge+ and since then, it has become really slow that it takes forever to open my emails. Before the update, it only takes a second or two to open my messages so I’m thinking maybe I could remove the update from my phone so I can use it like before. Is that even possible? My phone is setup to download emails that I also received on my computer and most of the emails I received are work-related so they’re important. I have to read them even at home that’s why I need this phone but now it’s acting up. Can this be fixed?

Troubleshooting: Well, a reset can definitely make your phone run faster again but I understand if you’re hesitant to do that due to a lot of apps you already installed on your phone as well as the number of files stored in it. So, we will take a long route into fixing this problem.

Step 1: Delete the system caches as they may have been corrupted

Considering the fact that the problem started after an update, it’s possible that it’s caused by some corrupt system caches. So, the first thing you should do is delete all the caches so that they will be replaced with new ones.

The thing is, you don’t have access to individual caches, thus, you have to delete them all at once. You can do that by booting your Galaxy S6 Edge+ in Recovery mode and wiping the cache partition:

  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 Samsung Galaxy S6 edge+ logo screen displays, release only the Power key
  4. When the Android logo displays, release the Volume Up and the Home key (“Installing system update'” shows for about 30 – 60 seconds before showing the Android system recovery menu options).
  5. Press the Volume down key several times key to highlight “wipe cache partition.”
  6. Press the Power key to select.
  7. Press the Volume down key several times key to highlight “yes.”
  8. Press the Power key to select.
  9. When the wipe cache partition is complete, “Reboot system now” is highlighted.
  10. Press the Power key to restart the device.

After wiping the cache partition, the phone will take a little more time rebooting as it rebuilds the caches but once it becomes active, observe closely if the problem got fixed. If it’s still slow, however, then continue your observation by doing the next step.

Step 2: Reboot your phone in Safe mode and observe your phone

Observation is key to knowing what the real problem is all about. Booting it up in safe mode means you’re temporarily disabling all third-party apps that may have something to do with the problem. So, start it up in safe mode and see if the problem still persists:

  1. Turn the device off.
  2. Press and hold the Power key.
  3. When “Samsung Galaxy S6 edge+” appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. Safe mode in the bottom-left corner of the screen.
  7. Release the Volume down key when you see Safe Mode.
  8. Uninstall apps that are causing a problem.

Step 3: Find that app or group of apps that’s causing the problem

You only have to do this if the problem doesn’t occur in safe mode because it means one or some of the apps you installed is causing the problem. You need to find that app, reset it and uninstall it if the problem isn’t fixed.

Step 4: Backup your files and reset your phone

After all those procedures and your phone is still slow, then it’s time to backup all your files and data and then reset your phone. You may sync your phone with your Google account to copy your contacts, calendar events, etc. into the cloud. As to your files, photos, videos and music, you can copy them to the SD card or computer.

After the backup, make sure you disable the Factory Reset Protection and take note of your Google ID and password so you won’t be locked out of your device after the reset.

  1. From any Home screen, tap the Apps icon.
  2. Tap Settings.
  3. Tap Cloud and accounts.
  4. Tap Accounts.
  5. Tap Google.
  6. Tap your Google ID email address. If you have multiple accounts setup, you will need to repeat these steps for each account.
  7. Tap Menu.
  8. Tap Remove account.

Now, here’s how you reset your phone through the Recovery mode:

  1. Back up data on the internal memory.
  2. Turn off the device.
  3. Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  4. When the Samsung Galaxy S6 edge+ logo screen displays, release only the Power key
  5. When the Android logo displays, release the Volume Up and the Home key (‘”nstalling system update” will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  6. Press the Volume down key several times key to highlight “wipe data / factory reset.”
  7. Press Power button to select.
  8. Press the Volume down key until “Yes — delete all user data” is highlighted.
  9. Press the Power button to select and start the master reset.
  10. When the master reset is complete, “Reboot system now” is highlighted.
  11. Press the Power key to restart the device.

And this is how you reset your phone from the Settings menu:

  1. From any Home screen, tap the Apps icon.
  2. Tap Settings.
  3. Tap Cloud and accounts.
  4. Tap Backup and restore.
  5. If desired, tap Back up my data to move the slider to ON or OFF.
  6. If desired, tap Restore to move the slider to ON or OFF.
  7. Tap the back key twice to return to the Settings menu, then tap General Management.
  8. Tap Reset.
  9. Tap Factory data reset.
  10. Tap Reset device.
  11. If you have screen lock turned on, enter your PIN or password.
  12. Tap Continue.
  13. Tap Delete all.
