Google Contacts is Google's contact management tool that is available in its free email service Gmail, as a standalone service, and as a part of Google's business-oriented suite of web apps Google Apps.
Google Contacts can be synchronized with mobile devices and operating systems (e.g., Android, Symbian, iOS, BlackBerry, Palm, Pocket PC, or Windows Phone) or with PC applications (e.g., Microsoft Outlook or Mozilla Thunderbird) via third party software, and Google's own Google Sync app. In addition, any system that can sync via Microsoft's ActiveSync can sync with Google Contacts. There is also support for mobile devices that support the Microsoft® Exchange ActiveSync® protocol and/or the SyncML standard. There is built-in support for Google Contacts in Google's open-source mobile operating system Google Android. Google Contacts can be synchronized also by CardDAV.
- With introduction of higher-density screens and larger internal memories to Android devices, the Google Contacts system was criticized for supporting only low resolution photos, with size limited by 96x96 pixels. This issue was fixed on October 10, 2012 on devices with 'Jelly Bean' to a higher limit of 720x720 pixels. As of 15 February 2013[update], it was reported that Google Apps users still hadn't received the update yet, some two years later.
