What does error message "No eligible devices for app install. Your device already has this item installed." mean and how can I solve and fix it.
Google Play
The error means the uninstall process wasn't registered at Google Play Store. Without the uninstall process registered, Google Play Store still reports the app as installed on the device that's associated with your Google account.
*. Clear Data and Cache on Google Play.
*. Reboot your device.
*. If nothing helped then you can install whatever you want from Google Play Store from apkmirror.com or other Google Play mirror sites.
