Xiaomi Redmi Note 9 Pro v11.0.5.0 update fixes Widevine L1, HDR related bugs

Xiaomi launched the Redmi Note 9 Pro and Redmi Note 9 Pro Max in India early last month, featuring Qualcomm’s Snapdragon 720G chip, impressive quad-camera setups, a massive 5,020mAh battery, and support for up to 33W fast charging. Tushar from our team had the opportunity to review the Redmi Note 9 Pro and in his review, he encountered a bug that affected FullHD playback in OTT apps like Amazon Prime Video and Netflix.

Upon checking the DRM certification on the device, he was surprised to learn that the Note 9 Pro delivered contradicting results for the Widevine security level test. Instead of offering Widevine L1 support, the device displayed Widevine L3 certification in Netflix’s playback specification and it alternated between Widevine L1 and L3 in the DRM Info app. On top of that, the device didn’t offer any HDR certification.

At the time, Xiaomi had acknowledged the bug and had said that it would be rectified in a future OTA update. Sticking true to its word, the company has now started rolling out an update for the device which addresses the Widevine L1 and HDR related bugs. The OTA update (v11.0.5.0) is now rolling out to the Redmi Note 9 Pro and we’ve already received it on our review unit. While the update changelog only mentions ‘Optimized system performance’ and ‘Improved system security and stability’, we can confirm that it also includes a fix for the Widevine L1 and HDR issues on the device.

Following the update, the Netflix playback specification correctly displays Widevine L1 certification and the device is able to play FullHD videos without any issues.

As far as HDR support is concerned, the device now supports HDR playback in Amazon Prime Video, however, it still doesn’t offer HDR support in the Netflix app. In case you haven’t received the update on your device yet, you can download the update package from the links below.
