Today's wikiHow guides you to increase / decrease the size of items on the screen of Android devices (such as apps) by increasing / decreasing the default DPI (dot per inch: number of pixels per inch). This is a standard option in the Settings menu of any device running Nougat (Android 7.0) or higher, but you can also change the DPI on an Android device running Marshmallow (6.0). or below using the Android Studio Developer Kit (SDK) computer and developer toolkit. Note that the actual resolution determined by the monitor of the device cannot be changed.

   • See the number to the right from "density" (for example, density 420 (403,411 x 399,737)).

5. 

   Adjust the resolution. Import wm density resolution && adb rebootyou need to change resolution using the three-digit resolution you want, then tap ↵ Enter.
   • Larger numbers than the current resolution will cause on-screen items smaller, and vice versa.

Advice

• You can change your phone's DPI with some apps as long as the Android device is rooted.
• On-screen keyboard may be deformed after the resolution has changed. You can install a keyboard with an interface that matches the DPI ratio (like the GBoard) to fix this.

Warning

• In some cases, changing the DPI will cause compatibility issues when using Google Play to load apps. If this happens, you can return the DPI to its original settings, download the application, and then adjust the DPI again.
• When you increase / decrease the phone resolution to increase / decrease the size of items on the screen, you will not be able to adjust the screen resolution to HD (e.g. 720p - 1080p) because the sharpness is decided. by the physical screen of the device.
