If you install MX Player directly from the Google Play Store, you will get the version (paid) or the Ad-supported version. As of the latest updates, the standard version supports HDR partially .

Would you like a step-by-step guide for setting up or VLC for proper HDR playback instead?

Upon first launch, allow "All Files Access" so the player can index your HDR media. Step 2: Download and Install Custom Codecs

Note: Avoid downloading APKs from third-party sites claiming to be "MX Player HDR Edition." These are often outdated or contain malware. The official app includes all necessary HDR codecs.
