Samsung has been rather quick and regular in releasing monthly security updates to many of its Galaxy devices, and the May 2019 update is no different. It started rolling out said update a week back, beginning with Galaxy A9 (2018) and Galaxy Note 8 and has been steadily adding more devices to the list since then.
The Galaxy S7 (and S7 Edge), Galaxy A5 (2017), Galaxy A8 (2018), and Galaxy Tab A 10.1 with S Pen (2016) are the latest batch of devices to receive the May update. These devices have started receiving the update in the last couple of days in select markets around the world. As of now, the update for the Galaxy S7/S7 Edge is rolling out in the UK, in Brazil for the Galaxy A8 (2018), in Colombia for the Galaxy A5 (2017), and in South Korea for the Galaxy Tab A 10.1 with S Pen.
Patches seven critical Android OS vulnerabilities
While we cannot confirm for sure, the update appears to bring to nothing more than the latest security fixes. As detailed by Samsung, the May 2019 Security Maintenance Release (SMR) patches seven critical and dozens of high and moderate risk Android OS vulnerabilities, along with 21 Samsung Vulnerabilities and Exposures (SVE) items of varying severities that are specific to Galaxy devices.
Samsung tends to release software updates in phases, so it may not be available to all the eligible devices at once. To check if the update is available for your device, go to Settings and tap on the download option under the Software update menu. If you are impatient to wait for the update, you can download the newest firmware for these devices from our database and manually flash it.
