All Android users have their eyes on the next OS version, P. The upcoming Android operating system was announced by Google on March 7, 2018, and the first developer preview was released on the same day.Android P brought a lot of new features to the board. Few of them includes display cutout support, multi-camera support, image decoder for drawables, security enhancements, and much more. The OS is still in the beta program so you can actually expect more from Google.But the hype around Android P can&rsquo;t mar the success of Android Oreo and other OS versions. Irrespective of the OS version, Android is one of the widely used mobile platforms globally, and it offers a flexible landscape for customization. As Android P has still some time to get on the floor, thus my finding is heavily focused upon the Android Oreo 8.1 because it is the latest running OS.There are still many features that are not known to many of the people due to various reasons. Thus, I will be focusing on such features which are least used or are hidden under layers.Let&rsquo;s get started.1. App InstallsThe Android app installation can be annoying sometimes. Most of you must be knowing that, if you wish to install an app other than Google Play Store, it can be done by opting for installation from unknown sources. This will allow almost any app from untrusted sources to be installed on the device.With Android Oreo, you need to permit the Android app that&rsquo;s downloading the untrusted APK.How to do itOpen SettingsGo to Apps &amp; NotificationsTap on special App AccessSelect the Install Unknown Apps2.

Notification ChannelsGet more granular and consistent control over which notifications can appear and how intrusive they are. Notification Channels enable the users to have a sway over how notifications appear on their Android devices.

It is done by saving WiFi network to the GPS coordinates.However, the feature will not work if the location service is turned off or the device is low on battery.10. Easy ways to clear storage on Android OThe storage is an issue for many of the Android users.
