FAQs

Why am I getting the "App Not Installed: Package Conflict" error?
This error usually means you already have an app installed with the same package name as the one you're trying to install. This can happen if you're trying to install an update from a different source (e.g., APK vs. Google Play Store) or if you have multiple versions of the same app from different sources.
I've tried clearing cache and data, but the error persists. What else can I do?
If clearing cache and data doesn't work, try uninstalling any similar or older versions of the app you're trying to install. Sometimes, remnants of these older versions can cause conflicts. As a last resort, consider restarting your device or factory resetting it (back up your data first!).
