As early as Google officially released Android 5.0, HTC made it clear that it would bring updates to HTC One series users within 90 days. Naturally, it was slightly unexpected that it announced a ticket skipping. After bringing updates to the developer version, GPE version, and lock free version of M7 and M8, HTC said that due to the bug repair, it could not update M8 in all regions in its early promise, and it could only continue to apologize.
