Restart your phone. If it’s the first time you encountered such error or problem, then you must restart your phone first because it could be just a result of a minor glitch in the system. Or better yet, perform the forced reboot by pressing and holding the volume down and power keys together for 10 seconds or more.

After this, try to download the same application to know if the problem is fixed or not and if you’re still getting the same error, then move on to the next solution.

  4. Select the problematic device in the Choose a device dropdown and select Install.
  5. Check if the app is successfully downloaded/installed on the device.

Remove Google account and re-add it. Since it’s a Play Store issue, your Google account may also have something to do with it. So, to make sure that it’s not due to account syncing problem, try to remove your Google account from your phone. Then, reboot your device and add the same account back. After which, download the same application and see if it goes through this time. If it’s still the same, then try the next solution.

Backup your files and reset your phone. A reset will fix it provided you still have the stock firmware running on your device. The reset will bring the device back to its default configuration. However, you need to make a backup of your important files and data as they will be deleted during the process. After the backup, follow these steps to reset your phone:

  1. Back up data on the internal memory. If you have signed into a Samsung account on the device, you have activated Anti-theft and will need your Samsung 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.
