In the People app, you get the dialer, contacts, groups (including favorite contacts), as well as a call log. You can reorder tabs and remove the ones that you don't need (Groups or Call history).
Selecting a contact displays the basic details: name and photo, numbers, emails and such. That's just the first tab - the other tabs hold further details and means of communication, including email and a call log. The third one displays a contact's social networking updates.
Quick Contact view is available too, just tap on a contact's profile picture.
The dialer on the HTC Desire 510 combines your keypad, recent call list and contact list in one application accessible via a single icon. You switch between the view modes with side-swipes. There's smart dialing and it works as well as expected. Once you start typing on the keyboard, contacts will be filtered by name or by phone number. You can use a QWERTY keyboard for searching as well.
The smartphone packs a neat set of call-related tricks such as automatically silencing the ring of an incoming call just by putting the phone face down or raising the volume if the device senses it's in a pocket.
As for call quality we can't complain with the HTC Desire 510. The sound from the earpiece was clear and sufficiently loud and callers on the other end said we sound natural and clear.
The HTC Desire 510 disappointed in the speaker test. The loudspeaker sound quality is rather good, but it is among the quietest we've tested to date.

The HTC Desire 510 is capable of handling all sorts of messages - SMS, MMS, email. There's also Google Hangouts, which can connect you to Google contacts via either texts or video calls.
SMS and MMS messages are displayed in threads - you see a list of all conversations, each one is listed with the contact's photo, name and the subject of the last message, as well as a part of the actual message. Tapping a conversation brings up the entire message history with that contact.
Sense 6 intuitively lists all of your conversations in a single thread - whether you're texting the same person on a new number and then go back to the old one - it's all chronologically listed in a single thread.
The HTC Desire 510 comes with two email apps - the traditional Gmail app and the HTC Mail app, which merges all your email accounts into a single interface with a unified inbox.
The HTC email app uses a navy blue top bar and merges it with the status bar for a nice design accent.
As for typing, the Desire 510's on-screen keyboard offers well-spaced keys, but the overlay doesn't include any gaps between them. During use we found that this is only a cosmetic feature and poses no discomfort. The 5" display diagonal offers enough space for comfortable typing.
Trace keyboard is also available. You drag a finger over the desired keys and the phone predicts what you're trying to type. It works really well but language support is limited.
