Display Info is a free Android app developed by Wizard FX under the Utilities & Tools category. It provides a detailed report of the screen information retrieved from the system framework, including screen size, density bucket, dpi, logical density, scaled density, usable width, usable height, total width, total height, physical size, default screen orientation, and max GPU texture size.

What sets Display Info apart from other similar apps is that it retrieves all reported values from the system framework, not from a device database. This means that the physical size might differ from reality, especially if a custom dpi is being used. For example, if a custom dpi of 200dpi is being used on an HDPI device with 240 dpi and a 4.3 inch screen, Display Info will report a density of MDPI instead of HDPI due to the lower custom dpi, a logical density of 1.2 instead of 1.5, and a physical size of 4.7 inches, which is distorted by the custom dpi.

This app is particularly useful when trying to debug density bucket related bugs. Overall, Display Info is a comprehensive tool that provides accurate and relevant information for developers and users alike.
