A redesigned results screen makes it easier to understand how well you slept each night, and you can now check your habits and recommendations directly on your watch without having to reach for your phone.

• Automatically record cycling workouts
Samsung Health can now detect when you start cycling and record your workout automatically. You can also set whether to automatically map your cycling routes.

• Get heart rate guidance during running workouts
Your watch can provide personalized heart rate zones while you run to help you manage your exercise intensity.

• More accurate results for track runs
If you start running on a regular 400 meter track, your watch can recognize which lane you’re running in to give you more accurate results for laps and distances.

• Create your own exercise
Can’t find your exercise in the list of options? You can now create your own custom exercise that measures your distance, speed, route, and more.

• Keep your watch data safe
Files and data from your watch are periodically backed up to your phone when it's connected to your watch. You can also save backups to Samsung Cloud. Your phone needs the latest version of the Smart Switch app to use this feature.

• Transfer your watch to a new phone
It's easier than ever to switch from one phone to another. You'll still have your watch faces and apps after transferring.

• More call controls
You now have more control over calls without touching your phone. You can adjust the call volume, mute sound, and press buttons on the keypad, all from your watch.

Whenever the camera is open in Flex mode or Tent mode on your Galaxy Z Flip5 or Fold5, a camera icon will appear at the bottom of your watch face. Tap the icon to quickly access camera controls on your watch.

• Dictate text with the Home button
Just press and hold the Home button any time you're entering text with Samsung Keyboard to instantly switch to voice input.

• Let Bixby read your notifications
Bixby can read your notifications out loud if you have headphones connected to your watch. You can then tell Bixby what to do after the notification is finished being read. To use this feature, Bixby needs to be set as the default voice assistant for your watch.

Check the status of your watch's battery, storage, and memory and immediately fix any problems to extend battery life and keep your watch running smoothly.

• Control your watch without touching it
Universal gestures let you control your watch without touching the screen or pressing a button. You can assign various actions to gestures such as shaking your wrist, making a fist, or pinching your fingers.

• Organize apps in folders
Create folders to keep your apps organized so you can find the apps you need quickly with less scrolling.

• Keep your watch safe
If you set a PIN or pattern on your watch, you’ll need to enter the PIN or pattern before you can set your watch after a factory reset. This prevents your watch from being used by someone else if it’s lost or stolen.

• Added the new Samsung Health Monitor App(Blood Pressure and ECG).
* Available on Galaxy smartphones with Android 9.0 and later.
※ The Blood Pressure app and/or ECG app in the Samsung Health Monitor is available in countries where a regulatory clearance, approval or certificate for each app has been obtained.
We expect that the number of countries where the Samsung Health Monitor to be available will continuously increase in the order of securing an appropriate regulatory clearance, approval or certificate.
Note, although you may notice that the Samsung Health Monitor is downloaded to your device, the BP and/or ECG app is not activatable until necessary regulatory clearance, approval or certificate is secured

Some apps will need to be updated separately after your watch is upgraded.
