FakeCall

An open-source Android application to simulate incoming calls, featuring a modern Material 3 UI with dynamic Monet support.

Overview

Ever wanted to get that Feature of old Samsung phones to simulate an incoming call with audio on the originial phone app? Introducing FakeCall. Unlike other apps that merely mock a UI, this app integrates directly with the Android Telecom Framework to provide an indistinguishable calling experience. It has many features to make the call as real as possible.

Caution

This app won't work on Android 17 as of now! This is because of google deprecating/changing Provider settings constantly. Please help getting heard by google by going to this android issue and pressing +1.

Features

• Original Dialer: FakeCall uses your real Phone app to simulate the incoming Call by creating a Phone Account in android's TelecomManager
• Customizable: The app lets you customize the name of the fake phone account in the settings to match your real service provider.
• Schedule: Set exact Timers for when the call should come in
• Audio Support: You can upload audio files that play when the call is answered
• Call History: Simulated calls are being shown in call history
• IVR Mode: assign audio files to keys and make sub-menus
• Recording: record microphone audio of a Fake call
• Automation API: trigger calls from Tasker, MacroDroid, or ADB via a broadcast intent
• Accessibility Shortcut: schedule a fake call from the system accessibility button using saved defaults
• Quick Trigger Presets: save up to 5 presets and expose them as launcher app actions + Quick Settings tiles

Automation API

FakeCall exposes a broadcast receiver for automation apps.

Action

com.upnp.fakeCall.TRIGGER

Extras

• caller_name (String, optional)
• caller_number (String, optional)
• delay (Int, optional, seconds)

If one or more extras are omitted, FakeCall falls back to the saved Automation & Quick Trigger Defaults from Settings.

ADB example (recommended, package-targeted, no -n needed)

adb shell am broadcast -a com.upnp.fakeCall.TRIGGER -p com.upnp.fakeCall --es caller_name "Boss" --es caller_number "+49123456789" --ei delay 30

Windows cmd.exe (single line)

adb shell am broadcast -a com.upnp.fakeCall.TRIGGER -p com.upnp.fakeCall --es caller_name "Boss" --es caller_number "+49123456789" --ei delay 30

Explicit component fallback

adb shell am broadcast -n com.upnp.fakeCall/.ExternalTriggerReceiver -a com.upnp.fakeCall.TRIGGER --es caller_name "Boss" --es caller_number "+49123456789" --ei delay 30

For Tasker, MacroDroid, etc. set:

• Action: com.upnp.fakeCall.TRIGGER
• Package: com.upnp.fakeCall

Accessibility Quick Trigger

Enable the FakeCall accessibility service and assign it to the system accessibility button or shortcut. When invoked, it schedules a fake call using the saved quick-trigger defaults from Settings and shows a short confirmation toast.

You can configure these defaults inside:

Settings -> Automation & Quick Trigger Defaults

You can also save up to five quick trigger presets from the same section:

• presets appear as launcher app actions (long-press the app icon)
• presets are available as Quick Settings tiles (FakeCall Preset 1 ... FakeCall Preset 5)
