Samsung is rolling out new security updates for its Galaxy branded flagship phones such as S5, S6, S6 Edge, S6 Edge+, Note 4 and Note 5 for users in regions including Asia, Australia, Europe, North and South America.

The rollout is part of the company's monthly Security Maintenance Release (SMR) process which includes all patches from Google and Samsung. The release is identical to the firmware update that Google released for its Nexus lineup in the beginning of February. The updates patched 10 security flaws and seven major vulnerabilities in the Android operating system.

There is also a patch for Qualcomm Wi-Fi drivers and fix for a critical error that could allow hackers to remotely gain access to the devices through text messages, reports Sammobile.
