Change Android Phone Default Resolution in 2 Minutes- No Root

Summary: In this guide, you will learn how to change the resolution of the Android phone screen without root and without settings. The method uses ADB commands to change the DPI value of the Android display. This value can be changed to increase or decrease the resolution of the Android phone under 2-minutes.

Android is one of the most popular smartphone OS which is continuously updated and upgraded with new security features along with significant improvements in performance every year. The best part, unlike iOS, Android gives you more control, which could be as good and as bad depending on the kind of user.

Power users take full advantage of their Android device power by rooting it. Root access lets you customize your Android the way you want and enable you to install custom ROMs.

Some devices even support multi-boot which means, you can install multiple Android OS such as CyanogenMod or Lineage OS ROMs and choose which one to boot-just like in Windows- all in one single device.

However, root voids your warranty besides it can permanently brick and damage your Android phone. But today, we have a simple trick that you can use to customize your Android resolution.

Fortunately, if you own a different device other than the Samsung Galaxy series, you can still alter your device’s display resolution by changing the DPI value of your device’s display via ADB without Root access.

The best part, you don’t need Root access.
