Mozilla developer Fabrice build an Android app that you can install and use the Firefox OS interface right on your Android device. B2gdroid app for Android make it very easy to install Firefox OS on Android devices. According to the developer this will not work on x86 devices, B2gdroid is an ARM build.
Install Firefox OS on Android Device
- Download Begdroid apk file on your Android device.
- Go to your Android device settings and enable the option to install app from unknown sources. Reason to enable this option because B2gdroid is not available on Google Play Store and we have to download apk and install it manually.
- Using file explorer on your Android device open the B2gdroid apk file that you downloaded earlier and install it.
Set Firefox OS as Default Launcher
Once B2gdroid installed successfully, press the home button and you will be asked to select the home launcher so select the Firefox OS and select Always to set the default launcher. Don’t worry you can revert the launcher from device settings later if you want to do that.
This will take few seconds to apply and load new Firefox OS launcher on your Android device. Once loaded you will see unlock screen like this.
Some users reported that they are getting errors and have Firefox OS crashed problem on their devices but on my Samsung Galaxy S5, i didn’t get any error but the launcher is not smooth and fluid. I would suggest you to reboot your device after installing and selecting Firefox OS as a default home launcher.
Restore Default Android Launcher
When you feel its time to load the default Android launcher on your device then got to Android Settings and then Application > Default Applications. Here select the Home and then choose the original TouchWiz home launcher. Now, enjoy the default Android launcher again.
