If you are lucky enough to get a shiny new Galaxy Z Flip, there are many great features to explore, such as the small 1.1-inch pill-shaped external display and Flex mode. But there are a few Android 10 settings that you can change to optimize the Z Flip even more, especially for better use with one hand.
Take a second andand then take a moment to try out these functions.
Turn the Z Flip fingerprint sensor into a scroll wheel
The Galaxy Z Flip begs to be used with one hand. And although Samsung's OneUI 2 interface makes buttons and windows easier to communicate with, it can still be difficult to reach the top of the screen for notifications. Fortunately, there is an Android setting that converts the fingerprint reader on the side of the phone into a capacitive scroll wheel to pull the notification tray down.
To enable this function:
1. Go to Settings.
2. Tap Advanced functions.
3. Select Movements and gestures.
4. Then turn on the slider Finger sensor gestures .
When your phone is open, pull your finger down from the top of the fingerprint sensor to pull down the notification tray. Perform the same movement a second time to display the control panel. Swipe up over the sensor to close the panel and the drawer.
Take a selfie with the on / off button
When the Z Flip is closed, you can double-tap the on / off button to open the outdoor camera for a selfie. A trimmed live preview is shown on the small 1.1-inch pill-shaped screen.
To take a photo, press the volume button or bring the palm of your hand to the camera to activate a camera timer and countdown.  Control the itsy-bitsy external display
In addition to being able to frame selfies when the phone is closed, the small external display has a few other applications. Tap the on / off button to display the date, time and battery status. Swipe your finger across the screen to the right to reveal notifications. Tap on one of the icons to see a short part of the message. When your phone is charging, the display shows the battery percentage and gives you an estimate of how long it takes for your phone to be fully charged.
4. Tap Open in split screen view.
5. Then choose the second app that you want to display below.
6. Once in split-screen mode, you can hold down the separation bar to resize each app.
Enabling gestures for better use with one hand
I found swapping the traditional Android navigation bar for gestures made the Z Flip easier to use with one hand.
1. Go to Settings .
2. Tap Display .
3. Select Navigation bar .
4. Then choose Gestures in full screen .
To use gestures, swipe up from the bottom of the screen to go to Home. Swipe up and hold to go to recent apps. And swipe from the right or left of the screen to go back.
