According to our previous reports, the Samsung S9 series will be officially upgraded to Android 9.0 in January 2019, and bring the latest One UI. From the previous test version, Samsung added night mode support for the series in the Android 9.0 update. Nowadays, Samsung has castrated this mode in the official version. Obviously, this feature is still under development.

According to the information given by foreign media SamMobile, Samsung has released the user instructions for Samsung S9 series upgrade Android Pie. From the description, the night mode does not seem to be fully realized, and the night mode is automatically enabled/disabled according to time and location.

In addition, in addition to nighttime castration, according to previous news, the Samsung S9 series upgraded to Android 9.0, Bixby also upgraded to 2.0. In short, let’s keep an eye on the upgraded Samsung mobile phone.
