Resolution Changer — Uses ADB

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
