The Android 10 beta showed us a lot of promising features, many of which made it to the final release. There are, however, a lot of them that were in the beta but never saw the light of day. Why Google chose to leave these out of the final build is anybody's guess, but we hope that they make a comeback in a future version of the operating system. Let's take a look at some Android 10 beta features that never made it to the final release.

Ever since OLED screens have become more commonplace, there has been a never-ending demand for Dark Mode to be implemented in just about every app and service. Android 10 finally introduced a system-wide Dark Mode, but it was lacking one minor function. Android Forks such as One UI let users schedule when the phone will automatically switch on Dark Mode. An early version of Android 10 let users do this, but the feature was pulled in the final release.
