AT&T Galaxy S6 and S6 Edge receive February security patch with QB3 update

AT&T has started rolling out a new update to its Samsung Galaxy S6 and S6 Edge, that installs the February security patch, comes as QB3 software version and is currently being seeded out over the air (OTA). Ah, if you were hoping for Nougat update, which went live yesterday for the Galaxy S6 and S6 Edge sets in Europe, you will be sad to know that your device still has some days left on Marshmallow.

This is another update from AT&T today, as only moments ago we saw the second largest carrier in USA roll out one for the Nexus 6, that came with even updated security patch, one for the month of March 2017.

The update arrives as build number G920AUCU5DQB3 and G925AUCU5DQB3 for the flat Galaxy S6 and Galaxy S6 Edge respectively, and weighs around 279MB-286MB in size. To be eligible for QB3, your current software version has to be baseband version ending in either of PKA, PK3 or PK5. If you don’t have any of these three, you must have more than one update waiting for you.

Besides the obvious security update, AT&T has also fixed the greyed out issue with AT&T Messages Backup and Sync (AMBS) option, while call quality has been improved.
