The selection of ay ition devices just got a whole lot smaller. recently yanked the G versions of the Xperia Z Ultra, G d 8.3, the original HTC One from ay.

These three devices were out of stock for several weeks before being pulled, according to Android lice, the site that first spotted the removal. at’s not clear, however, is whether the disappearance of these three devices means more smartphones are coming or if this is the end of ‘s ay ition.

Mining for Silver

th the HTC One (M8) available for a while now, getting rid of the original M7 makes sense. Debuting in late 2013, the G d 8.3 Xperia Z Ultra aren’t exactly spring chickens either—at least in smartphone terms. The ay ition of Samsung’s Galaxy S4, although still listed on ay, has also been sold out for weeks.

Motorola’s Moto G the HTC One (M8) were still available as G devices at this writing. There are also rumors that the Samsung Galaxy S5 will turn up as a ay ition device, perhaps ‘s well-received G3 will show up, too.

But there are serious reasons to wonder if might be getting rid of ay ition devices altogether.

Recent rumors point to a new program called Android Silver that may replace ay ition devices. Under Silver, would partner with multiple device makers to offer flagship smartphones running plain vanilla Android.

That’s close to what the ay ition program is right now—one difference being that Silver devices would be allowed to have a small selection of non-stard apps pre-installed, all of which would be removable by the user.

has yet to acknowledge the Silver program, although the company’s Android engineering chief didn’t deny its existence in a recent interview with Readite.

th ay ition devices seemingly winding down an Android debut slated for the fall we may see Silver make an appearance sooner rather than later. Until then, or unless more ay ition devices pop-up in the coming days, stock Android fans can still count on at least two devices to choose from beyond ‘s own Nexus 5.
