In terms of Android updates, Samsung hasn’t been the speediest in delivering them. Whether that has to do with it being the largest OEM for the OS is something to consider. In fact, it could have something to do with the leakage of the v6.0.1 Marshmallow betas intended for the Galaxy S6 and S6 edge to a Note 4 and an S5.
Note that we used singular terms for those devices. We can now confirm a plurality of Galaxy S5 phones now have the beta build from January 1.
A European unit got the unwarranted update this week (screenshots above). But since we’re talking about weeks between OTA spottings on S5 devices, we’re probably looking at a decent test period from this point with an official update timeline sticking to around April.
