With the firm idea of protecting the view of users and saving battery, several apps already have it and others are working on its "dark mode" version. In the case of Twitter , it is already working for Android phones that download the latest version of the app (8.18.0).
It is only necessary to go to the CONFIGURATION AND PRIVACY section where you can choose between the DIM mode that presents the interface in a bluish whole or that of LIGHTS OUT.
Some of the comments received by users are that their smartphones, after having downloaded the latest version of the app, cannot access the dark mode. In that case they are recommended to follow this route or a very similar one according to the brand of the cell phone: Settings> Applications> Twitter> Force close.
Next, go to the Storage section and select Delete Data. Generally these resources are suggested for Android 9 Pie and Android 10.
