In the first preview for developers On Android N, night mode was found to be one of the most striking features. This got even some developers to put the batteries and begin to add the automatic activation, at certain times, of the night mode in their own apps, as happened with Nova Launcher.
But finally Google decided to eliminate that night mode of the final version, so we've run out of it. In any case, if you already have Android 7.0 Nougat on your device, there is an app that allows you to activate the night mode so that at a certain time it is activated automatically and allows you to have a more rested view thanks to the darker tone it adds.
That night mode lies in the System UI Tuner, the advanced menu that allows us access special features from Android. It is the developers Vishnu Rajeevan and Michael Evans who have designed this app that allows you to activate the night mode on the mobile device that has Nougat.
The app is very simple and saves us from having to go through adb to rescue that mode that Google removed from the final version of Android 7.0. When you launch the app for the first time, a message will appear advising you to activate the System UI Tuner. This is done from a long press on the gear icon that you will have in the notification bar when you slide it down.
Now you only have to activate the "Enable Night Mode" button. You will be taken to the advanced Android menu where you will have the activation of the night mode as well as another series of options to change the brightness and color tone. You can use the Quick Settings tile to activate the Night Mode from there.
This mode is activated manually from that notification bar or automatically When the sun goes down It does not require ROOT and it is completely free.
