Samsung Galaxy Note 4 features are reported to include a UV sensor and retina
scanner.
A new report from SamMobile claimed that aside from the heart rate and fingerprint
sensor that will obviously arrive in the next-gen phablet, UV sensor and retina scanner
will also join the list of new features in the Galaxy Note 4. This means that Galaxy Note 4
will be the first smartphone to pack such a feature.
The UV sensor is rumored to be included in the S Health application coming in the
phablet. The Galaxy Note 4 is also expected to ship with a retina scanner for security.
Samsung smartphones initially packed a fingerprint sensor to address some of the
security problems faced by the users in using the smartphone.
The new UV sensor will measure the sun's UV radiation when the back of the sensor is
tilted at a 60 degree angle of elevation towards the sun. The UV measurement will help
prevent users from damaging their skin from the sun and guide users with the current UV
index level, according to SamMobile.
Aside from the aforementioned features, Samsung Galaxy Note 4 is also rumored to
pack a quadHD screen display with 2,560 x 1,440 pixel resolution, 64-bit processor,
Android 4.4.3 Kitkat operating system, 3GB RAM, and 3 megapixel front-facing camera.
The handset will be available in two variants packing varying processors. Just like the
previous Galaxy Note phablets, the international variant will come with Exynos chipset
and the unit released in the US will pack the Qualcomm's Snapdragon processor.
The phablet is speculated to make an appearance at this year's IFA event in Berlin in
September. This is backed up by reports that the Galaxy Note 4 will enter mass
production this month to meet the time for release. Other reports suggested that
Samsung Galaxy Note 4 will be released alongside other Samsung devices such as Gear
Live, Gear Glass, and Samsung Galaxy F or also dubbed as the Galaxy S5 Prime.
