Instant Messaging App Specific Settings for CellTracker

Configure these in-app notification and media settings inside WhatsApp, Facebook Messenger, Viber, Telegram, and Skype so CellTracker captures all incoming and outgoing chats on non-rooted Android phones.

How Non-Root Chat Sync Works

Why In-App Notification Settings Matter

On non-rooted Android devices, CellTracker (« GPS ») captures incoming messages through Android's Notification Access and outgoing messages through the Accessibility Service. If a chat app hides message previews or turns off notifications, CellTracker cannot read incoming messages from the notification bar.

Prerequisite: First verify that both Notification Access and Accessibility Service are turned ON for « GPS ». See our Enable Accessibility Guide and Sync & Chat Troubleshooting.

Muted Chats & Android Go Devices

If a specific contact or group chat is muted inside WhatsApp/Messenger, or if the notification bar never displays the incoming alert, CellTracker cannot capture that incoming message via Notification Access.
