HTC is making good on their promise and keeping the new One A9 up to date with security fixes. Just three weeks after Google released the latest update to Android Marshmallow, unlocked US-based One A9 owners are getting the latest update rolled out to their phones via an OTA update. It is a far cry from other vendors, including HTC themselves on other devices, that take months to roll out a security update.
If you are in the US and have a One A9, the update was approved over the weekend and has started rolling out. How fast it will take for your device to see it is not clear but it should be pretty quick. HTC doesn’t have the same staged roll out process as Google does on their Nexus devices and second, quite frankly, there are not a lot of One A9’s in the wild. My guess is you should see it by mid-week if you haven’t already (but that’s my opinion, not fact).
