If PojavLauncher is not working on your device, start by ensuring that both the app Pojavlauncher and your Java runtime are up to date, as outdated versions can cause crashes or compatibility issues. Clear the app’s cache and data from your device settings, then restart your device to refresh system resources. If the issue persists, check your device’s GPU compatibility since PojavLauncher relies heavily on OpenGL or Vulkan support for running Minecraft. Additionally, make sure you’ve given the app all required permissions, including storage access. Reinstalling the launcher from a trusted source like the official GitHub page can also fix corrupted files or installation errors related to PojavLauncher APK.
