Multi-Window is one of the most awesome features that has blessed larger Android devices. You will never use a smartphone the same way once you try running two apps at once, but sadly this is a feature limited to very few handsets (mostly Samsung ones). This is why the whole Android modding community went nuts when it was discovered the Android M developer preview code included this featured, hidden deep within all those ones and zeroes.
People had to tinker with the phone to enable multi-window mode in the Android M developer preview, but it was definitely possible. The real question was whether this would also be the case for Android 6.0 Marshmallow when it became available, in its full glory. It turns out multi-window works, and all you have to do is follow the very same steps you did with the Android M developer preview.
The news comes from Reddit, where Android enthusiasts shared their experiences regarding the matter, and showed images as proof of this feature working. The process is not that simple, but those who know their way around rooting, flashing custom recoveries and running ADB on a PC should be fine.
And just in case those crazy words don’t manage to scare the faint of heart, the following might. Do keep in mind that rooting, flashing recoveries and tinkering with your device may harm it or void your warranty. Go on with this at your own risk and do your research, for you may be left alone if anything happens.
With that in mind, those who choose to continue can just follow the instructions over at XDA Developer forums, where pretty much all hacking and modding goodies come from. Have any of you tried this? How is it working for you?
