Fixing incoming calls for Mobile app (Android)

Why Calls Get Missed: Top Reasons

• Both mobile and web call settings must be switched ON for calls to ring.
• Android app permissions, like microphone and “display over other apps,” must be granted.
• Battery optimization may shut down Smarter Contact in the background—calls can go silent.

Quick Checks Before Deep Troubleshooting

Tick these off first:

• "Receive calls on this device" is ON in the mobile app.
• "Incoming calls" are enabled for your phone numbers in the web app.
• Device has WiFi or cellular data connection.
• The Smarter Contact app is up to date.
• The person calling uses the correct number.
