According to Xperia Blog, the "Night Light" option makes it easier for users to view their phones at night. This feature can be activated through the Xperia X's display settings, which will then tint the screen with a pink-ish amber color during night time.

The company claimed that this specific color variant enables users to read contents at night and to aid in good sleeping time as it reduces exposure to blue light. In addition, the "Night Light" also allows users to switch the feature on from sunset to sunrise, or the option to customize the exact timing of its activation.

Besides the "Night Light" option, the latest update adds the latest January 2017 Google security patches and a new version of the Xperia Home launcher (10.2.A.1.18), as well as enhancements in network handling, according to UH. The said update also offers Xperia's Transfer Mobile app.

Users who have previously raised concerns with noise cancellation and fingerprint tests should witness an improvement on their experience after installing the said update. After installing the new update, the Sony Xperia X smartphones will be offered with the build N4F26I9, which will be based on the Android 7.1.1 Nougat firmware.

The Concept for Android program of Sony Mobile is still under continual improvement on the Xperia X smartphone. Users running the experimental update will soon expect the OTA update rolling out soon since Sony Mobile still remained mum on its release date.

As for now, this update is only meant for those taking part in the Xperia X Concept program and its download size will be 47.4MB.
