Android Freeform mode is a new hidden feature in Android Nougat (7.0). According to the Android developer guide, “Manufacturers of larger devices can choose to enable freeform mode, in which the user can freely resize each activity. If the manufacturer enables this feature, the device offers freeform mode in addition to split-screen mode.” Although the developer guides species larger devices, this could be enabled on smaller devices as well.
Enabling Android Freeform Mode
Here’s how the average user can enable freeform mode on their Android device. The first option requires that you have the Android development Bridge (ADB) setup on your computer. If you do, all you need to do is type in the following:
adb shell settings put global enable_freeform_support 1
Then reboot your phone. When your phone reboots, you should now have an extra icon when you open up recents.
Tapping this icon should allow you to open apps in freeform mode. However, this doesn’t seem to work on Android 7.1.2 or my Galaxy S8 running Android 7.0.
option 2
The easier option is to download the app called taskbar. Within the app, enable the freeform mode. It will give you a small launcher at the bottom of the screen. When you open an app through that launcher it will launch in freeform mode. Not every app will be compatible though.
