GS5-vs-GS4-heart-rate

The new Galaxy S5 boasts a ton of fancy new features, but one of the things Samsung has been pushing most since the handset was unveiled back in February is its built-in heart rate sensor. But just how revolutionary is that new sensor?

Well, as it turns out, not very. In fact, based on the hands-on video below, you can get the same results using your smartphone’s camera and LED flash with an app like Heart Rate Monitor from Runtastic.

We already know the Galaxy S5 is likely to sport a 16-megapixel camera, thanks to a sample photo that was published on Flickr earlier today. But Samsung looks set to make other changes to improve its photography capabilities, too.

The South Korean company has today teased a new LED flash module on its blog that “will be used in the next Galaxy smartphone.”

While Android’s notification system is far superior to the iPhone’s in almost every way, Google could certainly make some improvements to the way in which we receive alerts when our smartphones are locked. All we get with stock Android is a tone and a blinking LED.

Fortunately, there are some third-party solutions that offer a lot more. SlideLock displays iPhone-style notifications on your lock screen so that you can read messages and emails without having to unlock.

HTC-One-M8-sensors

HTC is set to announce its second-generation One — codenamed the “M8” — in March, but like a lot of the devices that came before it, the Taiwanese company has been unable to keep it under wraps until the big day.

Photos of the device that have surfaced online this week reveal a mysterious new sensor that sits above the handset’s rear-facing camera — plus a dual LED flash. The overall look of the handset itself, however, will be almost identical to its predecessor.

Moto-X-notification-LED

Did you know your Moto X has a hidden LED notification light that’s disabled by default? Motorola chose to use the handset’s excellent Active Display technology to notify you of new alerts as they come in, but the handset does have an unused LED light as well. And you can activate it if you have root access.
