I have close to 1,000 contacts synced to my Gmail account.
Using the dialer app (bottom left icon), they all show up if I select the icon labelled Contacts on the top. I can view and edit any of them.
But if I use the Contacts app (bottom right icon), only the first 50 or so contacts are accessible.
The same behavior happens if I select those two apps from the Apps Screen. I suspect that an app or a data file is corrupted.
Is there a way to shut down and restart the Contacts app? Powering down or removing the battery has no effect.
