As we were telling you yesterday, Galaxy Note 2 has multi-windowing, but with some limitations. As a result, not all applications can be used by this new feature.
Luckily, the xda developers offer a way to get around this limitation, very easily. After having talked about it yesterday, we suggest you take action today in this tutorial.
It will only take a few minutes and you will be able to have multi-windowing for all applications on your Galaxy Note 2.
But before you start the procedure, and as for flashing, you should know that we decline any responsibility in case of brick or loss of data from your phone. Even if the operation is simple and extremely rare, there is no such thing as zero risk.
Beforehand, your Galaxy Note 2 must have deodexed firmware.
To perform this operation, your terminal must also be rooted. If this is not the case, just follow our dedicated tutorial (available here).
Start by downloading the v2.FlashBarServices-MOD.zip file by clicking here. Then copy it to the internal memory of your smartphone.
Now turn off your device and restart in Recovery, by pressing the Volume Up, Home and Power buttons simultaneously. Navigate through the menu with the Volume button and confirm with Power.
Now choose install zip and then install zip from sd card and then select your v2.FlashBarServices-MOD.zip file. Confirm the installation and wait a few moments.
Once the operation is done, go back to the main menu and choose reboot phone now.
Now copy THE file specific to the firmware on your Galaxy Note 2 (Settings -> About phone-> Version number):
Flash the file you just copied in Recovery again, using the same method as before.
Once the installation is complete, restart your phone. You have now bypassed the application limitation for multi-windowing. Now split your screen in two as you wish.
And if you want to revert back to the original version, the xda developers also offer a restore of the original ROM.
