I'm running stock, rooted Sense 5. 4.2.2/Sense 5 wasn't released too long ago. Is it possible for manufacturers to just update system apps from the Play Store BEFORE they announced support for this with the M8?
Now, I don't download very many apps on the Play Store, so my Play Store Installed Apps list is quite short. I've never seen this app on the list. Perhaps more can pop up when it finds updates HTC pushes?
The update was found yesterday, though the update day reads 20 March 2014. Filtering by device model, it seems all comments on the Play Store listing from our very device were made within the last two days.
What I hope this means is that HTC will update Sense components for our devices via the Play Store, if this app's update indicates any possibility in doing so.
