The main purpose of these troubleshooting procedure is to determine the real issue and formulate a solution to resolve it. Don’t you worry, these steps are safe and won’t damage your device.

First solution: Do a soft reset and try fixing Play Store 921 error

This is a simulated battery pull procedure that will refresh your phone’s memory and reload all applications and services. It’s a very effective solution for problems that are caused by some minor firmware-related glitches or issues. You must do this first as the error may have been triggered by a firmware problem considering the fact that it’s one of the core applications. Here’s how you do it:

  1. Press and hold the volume down button and don’t release it.
  2. Now press and hold the Power key while holding down the volume down button.
  3. Keep both keys held down together for 10 seconds or more.

Once soft reset is done, try to download any app to see if the Play Store 921 error message will still show up. If it still does, then move on to the next solution.

Second solution: Boot your phone in Safe mode

It is possible that this problem won’t occur when all third-party applications are temporarily disabled. So, run your phone in safe mode and then try downloading an app. Here’s how you run your phone in safe mode:

  1. Turn the device off.
  2. Press and hold the Power key past the model name screen appearing on the screen.
  3. When SAMSUNG 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. When Safe mode appears in the bottom left corner of the screen, release the Volume down key.

Once the phone is already in safe mode, open the Play Store and try to download any app. If the Play Store 921 error still shows up, then move on to the next solution as it might be due to a network issue.

Third solution: Reset your network settings

Another possibility to consider that this issue is happening is to check if you have a stable internet connection. You can visit any website or open an email to verify if your internet works well. Because if not, that may be the reason that your device failed to download and the error message showed on your screen. By resetting the network settings, you are making sure that the connection is stable. So, follow these steps to do it:

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap Settings > General Management > Reset > Reset network settings.
  4. If you have set up a PIN, enter it.
  5. Tap RESET SETTINGS. Once complete, a confirmation window will appear.

Fourth solution: Delete Play Store Cache and Data

It is also possible that the problem originated from corrupt Play Store cache and data. At this point, it’s better to delete them so that they will be replaced with new files. Most of the time, this procedure will fix any app-related problems and it’s proven to be effective. So, follow the steps below to do it:

  5. Tap Storage.
  6. Tap Clear data and then tap OK.
  7. Tap Clear cache.

After resetting the app and the Play Store 921 error still shows up, then you have no other choice but to reset your phone.

Fifth solution: Perform Master reset

It is necessary to perform the master reset because the Play Store is one of the core applications and if there’s a problem with it, it’s possible that it’s just a result of a firmware issue that you don’t know about. A master reset will always address firmware-related problems and that’s what makes it very effective especially against this type of problem.

However, before you actually reset your phone, make sure to create a backup of your important files and data as they will all be deleted during the process. Also, we recommend that you remove your Google account from  your phone so that you won’t be locked out of your device after the reset. Once everything is set, follow these steps:

  1. Back up data on the internal memory. If you have signed into a Google account on the device, you have activated Anti-theft and will need your Google credentials to finish the Master reset.
  2. Turn off the device.
  3. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  4. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  5. Press the Volume down key several times to highlight “wipe data / factory reset.
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, “Reboot system now” is highlighted.
  10. Press the Power key to restart the device.

After the reset, set your phone up again and make sure it’s connected to a network. Then, log in with your Google account and open Play Store. Try downloading an app to see if the Play Store 921 error disappeared.
