I'm thinking about switching to the HTC One from the iPhone. Can someone with the phone confirm whether the phone's stock email app (the one you use to connect to exchange, not the gmail app) supports conversation/threaded view?
Yes, it does and it's much nicer than other Android phones that support conversation/threaded views in email. For example, on the Samsung Galaxy devices the conversation view is atrocious (it groups every single email into a conversation, even if it is the only email in that conversation).
But the HTC stock email's conversation views are very similar to the iPhone views.
I've attached a couple of screenshots showing you how it appears. View attachment 92518
