Samsung Electronics Co., Ltd. (LON:BC94) (KRX:005930) traditionally launches a slew of accessories along with its new smartphones. In the past, it has brought flip cover, wireless charging covers, screen protectors and more for its devices. But the company is going a step further this time. According to SamMobile, the Korean electronics company is developing an ultrasonic cover for the Galaxy Note 4.

How will the Galaxy Note 4’s ultrasonic cover work?

If the rumor pans out, the ultrasonic cover will improve the lives of select Galaxy Note 4 users. It will help users with partial or full visual impairment. Here is how the ultrasonic cover would work. It sends out a burst of ultrasonic signals to detect nearby objects and relays an audible alert to the smartphone, helping the visually-impaired user move around easily. Sources told SamMobile that the ultrasonic cover will have three range modes: short, middle and long.

In another development, the AnTuTu benchmarks suggest that the Galaxy Note 4 will sport a powerful 64-bit Exynos 5433 processor. Benchmark tests show that Exynos 5433 is only behind Nvidia’s latest Tegra K1, but faster than the Qualcomm Snapdragon processors found in most high-end devices. According to GSM Arena, the Exynos chipset in the Galaxy Note 4 has four Cortex-A57 cores and four Cortex-A53.

Galaxy Note 4 to sport powerful processors

AnTuTu benchmark shows that the Exynos 5433’s performance is about 10% better than the Snapdragon 805. Reports suggest that there will be two versions of Galaxy Note 4, one running Exynos 5433 and another one with Snapdragon 805. Qualcomm’s processors integrate an LTE modem, so the Galaxy Note 4 with Snapdragon 805 will likely be sold in LTE markets such as the United States.

Samsung will officially announce the Galaxy Note 4 on September 3. Reports from reliable sources suggest that the device will boast of a 5.7-inch QHD display with 1440 x 2560 resolution. Other features include 16MP main camera, 3MP front camera, 3GB RAM, and internal storage of 16GB, 32GB and 64GB. These are the features Indonesian online retailer Erafone listed on its product page for the Galaxy Note 4. Erafone was taking pre-orders for the device, showing its price at $813.
