How to take a screenshot on Galaxy Note 4?

How to take a screenshot on Galaxy Note 4?

When you want to show  someone remotely the Galaxy Note 4 screen, e.g., the achievement in a game, booking proofs, ordering info, some key information on a website, location in the Google Map, a Galaxy Note 4 screenshot is the most simple way to deliver such info.
But how to take a screenshot on Galaxy Note 4?
Luckily, there are many different methods to take screenshot on Galaxy Note 4.
In this guide, I will show you 3 different methods of taking a screenshot on Galaxy Note 4 without using any apps, or connecting to other devices. In other words, you can take a  screenshot on Galaxy Note 4 directly. No apps, or connections are involved.

Method 1: Take a screenshot on Galaxy Note 4 with Home and Power button

In the early days,  most Androidphones had a hardware home button. The Home button and power button combination is usually for screenshot.
Samsung is a few Android manufactures who refuse to bury hardware home button. So, you can have a simple way to take  a screenshot on Galaxy Note 4.
On any screen, press and hold power button and Home button simultaneously to take a screenshot on Galaxy Note 4.
In the reality, it is hard to press and hold two buttons simultaneously. So this may cause one of the two problems:
  1. Galaxy Note 4 exits current app and return to home screen. This means you press Home button too early.
  2. Galaxy Note 4 shows power options (restart the phone, shutdown the phone..). This means you press Power button too early.
The secret of successfully taking a  screenshot on Galaxy Note 4 is to press and hold the power button “slightly” earlier.
There is a reason for this secret. Home button will response normally within 100ms (about 0.1s) once pressed. But power button only responses usually after 500ms (0.5s).
Using Home button  and Power button to take a screenshot works not only on Galaxy Note 4, but also on almost all Galaxy devices from Samsung.

Method 2:  Take a screenshot on Galaxy Note 4 by swiping your palm over the screen

The second method of taking a screenshot on Galaxy Note 4 may require patience. But it is fun.
You can simply swipe your palm over the Galaxy Note 4 screen as shown below to take a screenshot on Galaxy Note 4.
take-a-screenshot-on-galaxy-note_4-swiping-palm
By default, this feature is turned on. But you may accidentally turned it off if you find this method is not working.
You can enable this feature by following these steps:
Step 1: Go to settings –Motions and gestures.
Step 2: Tap Palm swipe to capture if it is off.
Step 3: Turn it on by drag the switch to right until the color is green.
take-a-screenshot-on-galaxy-note_4_settings-motions-gesturestake-a-screenshot-on-galaxy-note_4_crop_enable-palm-swipe-settings

Again, this palm swiping method of  taking a screenshot on Galaxy Note 4 also works on most other Samsung Galaxy devices.

Method 3:  Take a screenshot on Galaxy Note 4 with S your S Pen using Screen Write (air command)

In old Galaxy Note devcies (Galaxy Note, Galaxy Note 2, Galaxy Note 3, Galaxy Note 8.0, Galaxy Note 10.1, Galaxy Note 10.1 2014 edition and Galaxy Note Pro), you can take a screenshot by  holding the S Pen button, then tapping and holding the S Pen on the screen.
But this S Pen method does NOT work for Galaxy Note 4, due to the new smart select feature in Galaxy Note 4.
Then, can I take a screenshot on Galaxy Note 4 with the S Pen?
Yes, you still can use S Pen to take a screenshot on Galaxy Note 4.  But now you need use one of the four air commands in Galaxy Note 4screen write.
Air command will be launched  when the S Pen  is removed from the slot, or when the S Pen is hovering over any part of the screen with S Pen button pressed.
In the four options of air command, tap screen write to take a screenshot on Galaxy Note 4.
Once the screenshot is taken, you will be offered the options to edit, share, and save the screenshot, as shown below. Tap the check symbol to save the screenshot.
Please note, when screen write is used to take a screenshot on Galaxy Note 4, the editing option is always provided and the screenshot is NOT saved until you tap the check symbol.  This behavior is different from the previous 2 methods.
take-a-screenshot-on-galaxy-note_4_using-screen-write-air-commandtake-a-screenshot-on-galaxy-note_4_using-screen-write-air-command-edit
Screen write was introduced in Galaxy Note 3. So this method also works on Galaxy Note 3, Galaxy Note 10.1 2014 edition and Galaxy Note Pro.

Are there any other methods to take a screenshot on Galaxy Note 4?

Yes, there are some other methods to take a screenshot for Galaxy Note 4.
One of the most common method for all Android devices is throughAndroid debug monitor.  But this required enable some developers options and USB connection with the PC.

Do you have any problems to take a screenshot on your Galaxy Note 4?
