According to Sammobile, Samsung is considering a processor upgrade for its flagship phablet Galaxy Note 4 and is testing the device with Qualcomm's upcoming Snapdragon 810 for some major carriers in South Korea. While Sammobile doesn't provide a confirmed testing carrier list, it speculates that LG+, SKT, and Olleh, might be the ones testing it as yet.
To remind you, the Samsung Galaxy Note 4 is already available in two processor variants depending on different regions - an octa-core Samsung Exynos 5433 SoC (quad-core 1.3GHz Cortex-A53 + quad-core 1.9GHz Cortex-A57) variant (Review | Pictures), and a quad-core Qualcomm Snapdragon 805 clocked at 2.7GHz.
While Qualcomm has not revealed the specifications of the Snapdragon 810 chipset, reports, the new 64-bit Qualcomm Snapdragon 810 includes four Cortex A57 cores clocked at 1.9GHz and four Cortex A53 cores clocked at 1.5GHz.
Meanwhile, there are also rumours about a new Samsung Exynos processor that will feature Cat. 10 LTE connectivity. According to Korean media reports (via Naver), the new Exynos chipset might ship with upcoming Samsung devices as early as next year, probably in the rumoured Galaxy S6 as well.
On the other hand, the latest of Samsung's anticipated single-letter named series of devices, the rumoured Galaxy E series, have been spotted on a company UA profile listing. Listed as the SM-E500F and SM-E700H, the devices are expected to be named as the Samsung Galaxy E5 and Samsung Galaxy E7, similar to recently launched Galaxy A series devices.
The Samsung UA profile listing (via Galaxyclub) suggests that both devices will have a 720p display. The SM-E500F will feature a 1.2GHz processor and SM-E700H will feature a 1.5GHz processor.Earlier, the two alleged Galaxy E series devices were spotted on Indian export/ import website Zauba with model numbers SM-E500F and SM-E700F. While the listing did not reveal much about the two devices, it had suggested that both will feature dual-SIM support and 5.5-inch touchscreens.
