How to get new updates
Since the APK app is not on the Play Store, it does not update automatically. However, when 999 joya releases a new version, a notification or banner usually appears inside the app. From there, or through the official channel, you can download the new APK file and install it over the existing one — you do not need to remove the old app separately, and your data will not be deleted.
Before updating, check that your phone has enough storage. The installation steps are the same as the first time — just open the file and tap "Install" to get the new version.
Always avoid downloading updates from any link or source outside the official channel. Files from third-party sites may contain malware.
