The carrier Telus has some problems with the Marshmallow updates for the Samsung Galaxy Note5, Galaxy S6 edge, and Galaxy S6 edge+. Previously the Note5 and S6 edge+ were supposed to get the Marshmallow firmware on March 9 while the S6 edge update was scheduled for March 16.
As it turns out, Telus had some minor setbacks, and those updates will be postponed for a few days. The Note5 and Galaxy S6 edge+ updates will arrive on March 13 while the S6 edge firmware will be ready for distribution on March 30.
The regular Galaxy S6 Marshmallow update for the Telus model is still coming on April 13, no changes here.
