Display density is measured in dots per inch (DPI). It determines the size of UI elements on a display of a given device. A higher display density means that users can see more interface elements at once. On the other hand, a lower display density means that fewer UI elements will be visible on the display, and the elements will be bigger. Tasker Beta has now added a Display Size option to change the display size dynamically.
To recap, Android 7.0 Nougat introduced a display size adjustment tool which enabled users to change display density (for example, from "Large" to "Small") without having to use ADB. The display size adjustment tool in Android acts globally, however. If users set a higher display density, then they will see more user interface elements (such as more lines of text on the display) in every single app as well as the system UI. They cannot dynamically adjust the display density on a per-app basis.
In the past, Paranoid Android (PA) had a popular feature that allowed users to set the DPI on a per-app basis. They could set a high DPI for the system, but have a low DPI for an app such as the Google Play Store or Google Chrome, for example. The feature has not been present in newer Paranoid Android builds. Joao Apps has now added the feature to Tasker Beta 5.3b.
The way the feature works is simple: users can select Action Category > Display Action > Display Size and then edit the display density from Smallest to Largest.
Other new actions in the latest Tasker beta include a toggle for switching NFC on/off, hide status bar icons, and force display rotation.
