Samsung’s official website dedicated to mobile phone safety said the company started rolling out the latest Android update to “major flagship models” as part of the monthly Security Maintenance Release (SMR) process.

This update consists of security patches from both Google and Samsung. The South Korean company has not specified names of devices for which the update is available, but GSM Arena cited an earlier report to say the Galaxy S5, Galaxy S6, Galaxy S6 Edge variants, Galaxy Note 4, Note Edge and Galaxy Note 5 are all scheduled to receive the February security update. In addition, the Galaxy Tab S and Tab S2 would also be eligible for this update.

The Galaxy Tab S2 has reportedly started receiving the security update already. Apart from Samsung, devices from Huawei, Motorola, BlackBerry and Nexus have all received the update already.

We reported last week that the Galaxy S6 Edge+ started receiving the Android 6.0.1 Marshmallow update firmware in South Korea, where the Galaxy S6, Galaxy S6 Edge and Galaxy Note 5 have all already received the firmware. The same Marshmallow update is also being rolled out to Galaxy S6 and S6 Edge in the U.K. via Vodafone. Not long ago, T-Mobile announced that the all European versions of the S6 will receive the update soon. With South Korea and the U.K receiving the Android 6.0, it is safe to assume that U.S. variants will get the updates shortly.

Galaxy Note 4 owners in Hungary have received the Android 6.0 Marshmallow update, and users in the U.S. and the U.K. will reportedly get the update in March or April.

Meanwhile, the latest Galaxy S7 and Galaxy S7 Edge with Android 6.0 Marshmallow on board will hit store shelves in March.
