Telus has commenced rolling out the Android 6.0.1 Marshmallow update to its variant of the Galaxy S5. The update weighs in at 819MB, and includes the April security patch.
If you're using the Galaxy S5 on Telus, now would be a good time to head into your phone's settings to download the update. The global variant picked up the update late last month, so it won't be long before we see Marshmallow rolling out to more Galaxy S5 variants across the globe.
As for other phones on the Canadian carrier, an upgrade document from last month shows that the Galaxy Note 4 is slated to pick up the Marshmallow update on May 16.
