Samsung's sixth-generation Galaxy Note phablet is already being heavily rumored in the media, but earlier iterations of the company's flagship phablet continue to remain fairly powerful and capable devices in their own rights. That includes the fourth-gen Galaxy Note model, which was introduced by Samsung back in late 2014. The device received its Marshmallow update earlier this year, making an already-capable device even more versatile with new features, tweaks and enhancements that were lacking with Lollipop and certainly, with KitKat, which is what the device was originally shipped with in the first place. While Marshmallow itself brought its own native goodies to the device, Samsung has also reportedly streamlined its TouchWiz UI, which had often been criticized in the past for being bloated, heavy and unintuitive.
However, even as Samsung cleaned up its TouchWiz UI much to the relief of buyers worldwide, the Galaxy Note 4 received one interesting new feature as part of the refined and refreshed TouchWiz update. The feature happens to be 'Screen-off Memo', which was one of the exclusive Note 5 features that was heavily advertised by Samsung while launching the device last year. The feature allows users to 'write' on their device with the screen turned off. While the feature should be enabled by default after the installation of the official Marshmallow-based ROM, the tutorial below should allow users to enable it manually if required.
The first step is to go to the 'S-Pen Menu' from the 'Settings' option. Once there, you'll need to scroll down a bit in order to get to the 'Screen off Memo' setting. As mentioned already, it should be checked by default, but if it isn't already, just enable it. Once that setting is activated, the Galaxy Note 4 becomes capable of taking notes even when its screen is off. Not only that, the software also allows users to edit, save or delete their notes with the screen still turned off. While it's not really an earth-shattering feature, it is still a pretty cool one, admittedly. It allows users to quickly jot something down without having to turn on the screen, saving not only time, but also battery life; something that continues to remain an issue with many modern-day smartphones.
