The Samsung Galaxy S5 may be a smaller upgrade than the Galaxy S4 was from the S3, but it still follows Samsung's pattern of throwing in almost every software feature it can manage -- including a fingerprint scanner, heart rate monitor, and ultra power-saving battery mode.

Here, you're looking at the lock screen on the phone's 5.1-inch 1080p HD AMOLED display. Colors are bold and bright. From here, you can take a photo (even if you enable a password), check the local weather, and see alerts like missed calls.

The notifications tray is another area that gets a tiny visual redo. In addition to showing important notifications, you can adjust the display brightness, mute the sound, and turn wireless and GPS features off and on again. Two new buttons launch the phone's content finder and help you easily connect to other compatible devices.

It only takes a few minutes to set up a profile, and you can have up to three of them. Check out CNET's deeper dive of the Galaxy S5's snappy fingerprint scanner.

And if the fingerprint sensor is too newfangled, you can still opt for a pattern, a PIN, or an alphanumeric password. Even if you do set up a fingerprint scan, you'll have a backup password regardless.

The Galaxy S5's heart rate monitor is another hardware addition, and one that's unique to cell phones. You start the process through the S Health 3.0 app, which also includes a pedometer and exercise tracker.

Tips walk you through the process. To use the heart rate monitor, press your finger to the sensor just below the camera lens on the phone's rear.

CNET's Luke Westaway gives the heart rate monitor a go. An LED glows red when the monitor is active.

You'll need to hold still and keep quiet while it's measuring.

The Galaxy S5 measured Luke's heart rate at 96 beats per minute. You can blame that high result on the stress of covering a Samsung press conference.
