Resolution Changer — Uses ADB

About this app

Resolution Changer works by using a hidden Android API called IWindowManager. Originally, Google restricted access to this API starting with Android Pie, however, they allowed developers to disable the API blacklist by tweaking a Secure Setting.

Resolution Changer first unlocks the blacklisted APIs, and then applies the requested resolution and display density.

If you do not specify a height or width, Resolution Changer will simply use the resolution that is currently set by the device.

If you do not specify a density, Resolution Changer will try to calculate a suitable density based on the diagonal screen size of the device.

WARNING:
If you specify a broken resolution and are unable to fix it, follow these steps:
1. Connect device to PC
2. Open CMD or Terminal (depending on OS)
3. Type these commands:
adb shell wm size reset
adb shell wm density reset

Ratings and reviews

Awesome app, allows me to switch to lower resolutions so older games display properly, or I can use my 4K display in games as my device defaults to 1080p for anything other than media playback. Thank you for this app. P.S. I'd love to be able to set presets myself, it'd be really useful.

This app works great. Most of the people writing bad reviews have no idea what adb is and it shows lol. I will say that you may need some troubleshooting skills to get it to work properly (Xiaomi phones need the battery saver for the app disabled, for example). Once you get it to work, it does what it says on the tin.

I seriously like your app. This is the only app that can change resolution of the screen effortlessly. But, I give an input value that is much greater than default resolution, some touch areas of the screen are disabled. So I restarted my phone thinking that it would go to the default resolution. But it didn't. As the touch area is not working, I couldn't enter my password. What should I do now? I don't want my data to be lost. Please help. Edit: Usb debugging cannot be enabled from lock screen
