Android Oreo is coming to HTC U11, HTC U Ultra and HTC 10
Now that Google has made Oreos the favorite cookie among Android users, the big question is whether your Android phone is going to be a recipient of the new Android OS build. Even though you probably can figure out that the Samsung Galaxy S7 and Samsung Galaxy S7 edge will receive Android 8.0, and ditto for the Moto Z Force, Moto Z and Moto Z Play, once you start talking about models released in 2015, you really don't know what to expect. For example, will the Motorola DROID Turbo 2 be updated? We will have to wait and see.
At first blush, HTC's tweet yesterday stating that the HTC U11, HTC U Ultra and HTC 10 will be updated to Android 8.0 sounds like the company is going out on a limb with this announcement. But the manufacturer is merely picking the low-hanging fruit. The HTC U11 is the 2017 flagship, so that is a given. The HTC U Ultra was launched earlier this year, and the HTC 10 was the 2016 flagship. So truly, there are no surprises here.
In the tweet it disseminated with this
By the way, earlier this year Chailin Chang, president of smartphones and connected devices at HTC, pretty much guaranteed that the HTC U11 would receive Android O and Android P. His comment that "We may extend support to the next three versions of Android. It will depend on the hardware and software demands of the version […] and if it will bring value to the consumer," seems to promise no less than two update cycles for the current flagship model.
