Samsung Galaxy S10 and Galaxy S10+ uses heart rate sensors at the back, which have now gotten an added purpose, besides measuring your heart rate of course. In the latest update for both the phones, the heart rate sensor can be used as a visual indicator to check if your Galaxy S10 is actually wirelessly charging your other device. All Galaxy S10s are capable of reverse wireless charging, which lets you use the back of the phone to charge either another phone or any other Qi-compatible accessory.
The update is currently rolling out to the Galaxy S10 devices in India and our Galaxy S10 review unit immediately picked it up. The software update is about 464.08MB in size and the changelog indicates stability improvements to the camera and improved performance for the Wireless PowerShare feature. When Wireless PowerShare is enabled from the notification shade, an LED in the heart rate sensor module starts blinking blue, so you know that this feature is active. As soon as you place a Qi-compatible device on the back, the LED light turns red, to indicate that the device is charging. This is a thoughtful little tweak from Samsung's part as it makes it a lot easier to check if your device is charging or not, at a glance.
