The Samsung Galaxy Note 4 could feature a new ultraviolet sensor that will be used to determine the UV index.
The component will be able to inform the smartphone user of when it reaches harmful levels and will make recommendations based off of it. This includes telling them to put sun screen on.
The functionality will be integrated into the S Health app, however, the readings will only come when the user holds the device at "over 60 degree angle of elevation towards the sun against the back of the sensor."
There is no word on where the sensor will be located on the Note 4 at this time.
The Note 4 might also feature a retina scanner when it launches, according to a recent post by Samsung. The company put up a teaser of a phablet like device which could be the Note 4 on its ExynosTwitter account last week and hints at it coming with some kind of Eye scanner.
"Security can be improved using features unique to us," wrote the company. "That's what we envision. What would you use?"
The tag line listed in the top of the teaser reads "Unlock the Future." This points to the scanner being the main tool used to unlock the phone. Samsung also has a track record with adding new features to its devices related to the eye as it released the Smart Screen scrolling and pausing on the Galaxy S4 last year.
The Galaxy Note 4 is expected to launch sometime in the fall of this year. It will join the Galaxy S5 for Samsung's 2014 line-up and will compete with Apple's rumored larger iPhone model.
