Last November, Asus outed a list of devices that it would update to Android 6.0 Marshmallow. Unfortunately, no timeline for update rollouts was mentioned at that point. And here we are more than three months later, and Asus has yet to push the new software to any of its wares.
The good news is that now we finally have a (very rough) timeline to speak of. Asus will send out Marshmallow updates during the second quarter of this year, so from April to June. The company has revised its list of devices getting the Marshmallow treat, adding three smartphones that weren't in the initial roster.
These are the ZenFone Max ZC550KL, the ZenFone 2 Laser ZE551KL, and the ZenFone Zoom ZX551ML. They join the following devices which were already slated to receive the update: PadFone S PF500KL, ZenFone Selfie ZD551KL, ZenFone 2 (ZE550ML and ZE551ML), ZenFone 2 Deluxe ZE551ML, ZenFone 2 Deluxe Special Edition ZE551ML, and ZenFone 2 Laser (ZE500KG, ZE500KL, ZE550KL, ZE600KL, and ZE601KL).
