Smartphone manufacturers nowadays tend to offer some kind of digital audio optimization to enhance the performance of the speakers built into their devices. OnePlus, for example, collaborated with Dirac Research till the release of the OnePlus 6T, but switched to Dolby Atmos audio tuning since the OnePlus 7 series. Most of these technologies and solutions are deeply baked inside the firmware, thus modifying the existing presets usually requires root access. However, XDA Senior Member Rayekk has now discovered a simple trick (that doesn't require root access) to replace the barebones Dolby Atmos Settings on the OnePlus 7 Pro with a more feature-filled equalizer. We have tested the method on the OnePlus 8 and OnePlus 8 Pro without any issue, and this trick should also be possible with the regular OnePlus 7 as well as the OnePlus 7T series of phones.

Veteran OxygenOS users should be aware that OnePlus only offers three "scenario-based enhancements" - namely "Dynamic", "Movie", and "Music" - as the Dolby Atmos equalizer presets in these phones. The built-in presets come from the com.oneplus.sound.tuner package, which is itself a system-app. All you need to do is uninstall the package for the current user and then install a compatible controller app to unlock the full potential of your phone. The steps are listed below:

  1. Set up ADB shell access by following this guide.
  2. Turn on USB debugging on your OnePlus phone and connect it to your PC.
  3. Execute the following ADB command:
            <span >adb shell pm uninstall --user 0 com.oneplus.sound.tuner
    </span>
  4. This will uninstall the stock presets from the primary user profile. Now you can download the Dolby Atmos Equalizer extracted from the Razer Phone's Android firmware using this link.

Unlike typical third-party audio mods, the new equalizer seamlessly integrates with the OxygenOS firmware. While you can also restore the old presets using this ADB command:

        <span >adb shell cmd package install-existing com.oneplus.sound.tuner</span>
    

...You should remove other Dolby Atmos apps beforehand to avoid potential conflicts.
