Android’s monthly security update for November is making its rounds on the Samsung Galaxy S6 and Galaxy S6 Edge. The software should be hitting handsets wirelessly as of Thursday, but may take several days to roll out on all devices.

To check manually if the security update is ready for download users can access Settings > About Device > Software Update. Users should ideally install the software via Wi-Fi with handsets charged to at least 50 percent.

The Samsung Galaxy S6 is receiving software version G920TU V5 PK5 while the Galaxy S7 Ege is recieving version G925TUVU5EPK5. At this time T-Mobile has not updated the device support page with change log details on what users should expect from the update. However this information should come soon.

The update is likely a minor, possibly containing patches and general maintenance. The Galaxy s6 and Galaxy S6 Edge likely won’t receive any major software changed until they update to Android 7.0 Nougat. Samsung is currently developing Android 7.0 software for the Galaxy s6 and Galaxy S6 Edge.
