Google has recently updated the Google Contacts application for select Android devices to made it easier to edit contact details. The most significant change Google expanded the app's availability from just Marshmallow to Lollipop.
The app is still limited to Nexus, Android One, and Google Play Edition devices. Users running Lollipop on these devices can now add and edit contact data points such as name, number, and email allowing users to save to their Google account, fix duplicates, and call or message from the contact card. Google Contacts is free to download from the Google Play Store by folling the link below.
*Update* I was successfully able to download the APK (APK link below) install and run the new Google Contacts app on my Moto Z, Moto Z Force, and LG G5. Please comment below if you are able to install and run the new Google Contacts app on your non Nexus, Android One, or Google Play Edition phone.
