If you know your friends have Zangi, but you can't see them — or they appear as numbers instead of names. Check your internet connection Ask your friend about their connection Ask them to try messaging/calling you Make sure you are entering correct Zangi Private Number Try messaging/calling other Zangi contacts, see if the problem is with that one person or all contacts. Make sure you are using the latest version of the app. Force quit and relaunch the app. If that doesn't help, temporarily change the name of the contact in phone contacts (add a few symbols, then change back again). If that doesn’t work, re-login: app Settings → Log Out → then log in again. If you still can’t figure out what’s going wrong, contact support and send us a detailed description of the problem.

If the timestamp displayed on your received messages or the last seen time of your contacts are incorrect, please check the time and time zone configuration on your phone. You might need to re-adjust them. We recommend setting your date and time to Automatic or Network Provided. With this setting enabled, your mobile provider will set your phone to the correct time. If the incorrect time is displayed even with this setting enabled, then there might be an issue with your network. Please contact your mobile provider to address the issue. As a workaround, please modify your date and time settings and correct your time zone manually. Note: The time zone is different from the actual time. Make sure you select the correct time zone for your location.

To configure your time zone manually, please follow these steps for your phone:

• Android: Go to app Settings → General Management → Date & Time.
• iPhone: Go to app Settings → General → Date & Time.
