Resolution & DPI Changer

Resolution & DPI Changer lets you read and change the logical screen resolution and display density (DPI) Android uses. Every change starts as a timed test: the app records your current values and restores them automatically when the test ends, so an unusable value fixes itself. You can save presets, calculate proportional values, and add a Quick Settings tile, a launcher shortcut, or Tasker actions. Setup needs one route that your device supports: Shizuku, Wireless Debugging, a one-time permission grant from a computer, or root. The app changes logical overrides only; it cannot add physical pixels. Free on Google Play (contains ads and in-app purchases). Android only.
