This Galaxy S21 how-to guide explains the 8 supported touchscreen gestures on Galaxy S21 and demonstrates how to use them. Some advice on taking care of the Galaxy S21 screen is also covered.
This guide applies to all models and variants of Galaxy S21 phones because the touchscreen gestures are a common software feature on these phones.
Galaxy S21 supports 8 touchscreen gestures:
These are touchscreen gestures supported at the system level. Some apps may support other fancy gestures.
Tapping is the simplest and most frequently used touchscreen gesture on Galaxy S21.
You touch (tap) somewhere on the Galaxy S21 screen once, then move your finger away from the screen, as illustrated below.
When using DeX with a mouse, the corresponding operation is “click”.
The action of the tapping gesture depends on the object you touched and the app you are using. For example, if you tap an app icon or a file, Galaxy S21 will try to open it. If you tap a link, Galaxy S21 will try to open the corresponding webpage. But if you tap a quick settings button, you may just enable/disable the feature.
Here are some example usages of using the tapping touchscreen gesture on Galaxy S21.
You need to quickly tap the same location twice, as shown in the animation below, to register the double-tap gesture.
If the interval between two taps is too long (e.g., longer than 2 seconds), the gesture will be registered as two separate single taps.
When using DeX with a mouse, the corresponding operation is “double-click”.
The action of the double-tap gesture on the Galaxy S21 is usually to “wake up” or to enter a special mode. For example, you can double-tap on the screen to turn off the screen or to wake up Galaxy S21. You also need to use the double-tap (or single tap) gesture to access face widgets on the lock screen.
So, do not confuse the function of the double-tap gesture on Galaxy S21 with the double-click on a PC.
Here are some examples of using the double-tap gesture on Galaxy S21:
Similar to the double-tap gesture, the triple-tap gesture requires you to tap the same location quickly, but three times, instead of two. If you do not tap quickly enough, the gesture may be registered as three single taps or a double-tap with a single tap.
The triple-tap gesture is one of the special Galaxy S21 touchscreen gestures. It is designated for screen magnifying.
You can enable or disable it in Settings — Accessibility —Visibility enhancements—Magnification—Magnification shortcut —Triple tap screen.
On Galaxy S21, you can also use the accessibility button in the navigation bar or key combinations (Volume keys or Side key + volume key) to access magnification.
To register a long tap gesture, you need to tap on the screen, then keep the finger on the screen (hold) for more than 2 seconds, as shown in the animation below.
If you release your finger from the screen too early, it will be registered as a tap gesture.
When using DeX with a mouse, the corresponding operation is “right-click”.
On Galaxy S21, the action of the long-tap gesture is mainly to open the context menu or select an item.
Here are some examples of using the long-tap (tap and hold) gesture on Galaxy S21:
Your finger needs to touch the screen, then immediately drag your finger to one of the 4 directions (up, down, left, or right), as shown in the animation below.
During this period, your finger should always touch the screen without staying in any location too long. If your finger stays on one location too long, it will be registered as a long tap gesture or drag gesture.
If your finger leaves the screen too quickly (without swiping long enough), a tap gesture may be registered.
The most well-known use of the swipe gesture is to swipe to unlock. Of course, there are many different actions for the swipe gesture on Galaxy S21.
Here are some examples using the swipe touchscreen gesture in Galaxy S21:
To register the drag gesture, you need to hold (long tap) on an object then moves the finger on the screen. You can release your finger only when it reaches the desired destination, as illustrated in the animation below.
Once your finger leaves the screen, the drag gesture is registered.
When using DeX with a mouse, the corresponding operation is “left click (without release) and drag ”.
You may notice the drag gesture is somewhat similar to the swipe gesture. But the differences between these two Galaxy S21 touchscreen gestures are obvious:
As mentioned, the most common usage of the drag gesture is to move or relocate an item.
Here are some examples of using the drag gesture on Galaxy S21.
The pinch gesture requires you to move two (any two) fingers inward to a commonplace on the Galaxy S21 touchscreen, as illustrated below.
Here are some example usages of the pinch gesture.
The spread gesture is the opposite of the pinch gesture.
To register a spread gesture, you need to move two fingers outward (i.e., separate two fingers), as illustrated below.
Normally, the spread gesture is used together with the pinch gesture. Sometimes, they are considered as a pair of Galaxy S21 touchscreen gestures.
Galaxy S21 is not cheap, and screen repair is usually very expensive. So. it is important to use the touchscreen properly.
Screen burn-in is one of the most common screen issues. It is caused by showing static (fixed) graphics on part or all of the Galaxy S21 touchscreen for
extended periods.
You can easily alleviate such an issue by:
Please note, you can always press the Side key to turn off (or wake up) the screen.
In most regions, a plastic screen protector was pasted on Galaxy S21 when the phone leaves the factory. The quality of the free screen protector actually is decent and offers some protection for screen damage.
Of course, Samsung offers this screen protector because it is compatible with the under-display ultrasonic fingerprint reader. Some tempered glass screen protectors may not work well with the stupid fingerprint reader.
It is recommended to keep the screen protector unless you get a new screen protector.
Besides, you can also consider a flip cover for Galaxy S21 unless you hate cases on the phone. Frankly, unlike old-school plastics, the smooth finishing of the phone makes it “slippery” in the hands. A flip cover may save your screen!
If your budget permits, you may consider Samsung’s official flip cover: Galaxy S21 Smart LED View (LED Wallet) Cover or Galaxy S21 Clear View Cover (S-View Flip Cover).
You should not tap the Galaxy S21 touchscreen with any sharp objects.
Also, the touchscreen is sensitive enough so that you do NOT need to tap the screen with excessive force.
Some game players may delusionally feel it is faster when tapping with force. The truth is that it takes a longer time to finish your tap. The screen response time does not improve with the force when using any of the touchscreen gestures.
Electrostatic discharges can cause the touchscreen to malfunction. So, you should keep the Galaxy S21 touchscreen from contacting other electrical devices.
