The cover reportedly works by emitting ultrasonic sound (sound too high in frequency for humans to hear) to detect nearby objects in front of the users and provide feedback.
The report doesn't say how users will be notified of the objects. However, if the new cover works anything like Samsung's previous ultrasonic case for the Galaxy Core Advanced, it will warn users of obstacles by vibrating or via spoken alerts.
The Galaxy Core Advanced's ultrasonic cover added a protruding prong to the already sizable 4.7-inch handset. It's unlikely everyday users will want to throw this case onto the even larger 5.7-inch Galaxy Note 4, assuming the two share the same shape.
We're going to need a bigger box
Rumors so far have pointed to a new phablet featuring a Super AMOLED 2,560 x 1440 pixel display and an optically stabilized 16MP rear camera.
The smartphone has been said to come in two models with different processors: one with a 2.5GHz quad-core Snapdragon 805 chip and the other rocking a significantly faster octa-core Exynos 5433 processor.
Rounding out the rest of the spec sheet are 4GB of RAM plus storage options including 16GB, 32GB or 64GB, which users can stack up to 128GB of additional memory with a microSD card.
