Rooted note 4,spen keyboard switcher.

[Russ Smith]

For those that it may help, I'm using this tweak:
[App][Root] SPenBoardSwitcher 3 - Changing k… | Samsung Galaxy Note 3 | XDA Forums

SPenBoardSwitcher, using my favourite SwiftKey, then auto uses Stylus Beta while spen is removed. Simular to Samsung function I suppose but I get a much better full keyboard and a much better handwriting recognition keyboard. Working great, on Lollipop, model SM-N910F, Unlocked.
Will update and with battery impact if anyone's interested.

My Android line up: HTC One M7, Note 2, Moto G 4G, Oneplus One, Note 4.

Sounds like a plan, then.
