Short answerMuditaOS 1.2.1 (June 2022) improves Pure's call and audio quality with new audio parameters.

MuditaOS 1.2.1 is a Mudita Pure update from June 2022 that improves audio quality. It applies new audio parameters, after users raised concerns about how Pure sounded.

What changed

  • New audio parameters for better audio quality.

Use Mudita Center 1.3.1 or later to install it. Newer MuditaOS versions include these changes.

How to update

  1. Install the latest Mudita Center on your computer (Windows, Mac or Linux).
  2. Charge your device to at least 40%.
  3. Connect it to the computer with a USB-C cable and open Mudita Center.
  4. In Overview, look at the MuditaOS section. If you see Update is available, click Download Now, then start the installation.
  5. Keep the device connected and don't use it until Mudita Center confirms the update and the device restarts.

If your device is several versions behind, Mudita Center runs a sequential update and installs each required version in turn. On a Pure with a passcode, you enter the code after each step. More help: Updating a Mudita Pure or Harmony with Mudita Center.
