Grok on Android: Calls, Assistant, and Bot

Choose the Grok route you mean

Grok on Android can refer to four different routes, and the right answer depends on which one you mean. There is the consumer Grok AI app for chat, voice and media work. There is the separate Grok Bot Android app for assigning tasks to the Bot experience. There is the Grok API for developers and compatible model configuration. There is also FoneClaw, where a compatible model can help with reasoning while FoneClaw performs supported Android actions through its own phone-agent tools.

That separation matters for phone calls. A voice conversation with Grok is not the same as placing a phone call. Giving a task to Grok Bot starts work in the Bot route, while Android calling needs a phone-side execution path. Supplying an API key gives model access under the provider account; Android contacts, dialer access and calling permissions remain phone-side requirements. In FoneClaw, the model helps interpret the request, while the actual Android action follows FoneClaw's supported tool, permission and approval behavior.

The package IDs are also different: the Grok AI listing uses ai.x.grok, while the Grok Bot listing uses ai.x.grok.bot. Check the app name and package when comparing instructions, reviews or screenshots.

Understand what Grok Bot controls

The current Grok AI listing on Google Play describes the consumer Android app for answers, natural voice conversations, image and video generation, and picture upload. That is the app most people mean when they say they installed Grok on Android. It is useful for asking questions, speaking with Grok, analyzing images and creating media inside the Grok experience.

The separate Grok Bot Android listing points to a different product surface. It presents an Android entry for assigning tasks and continuing bot threads across devices, where available. Store visibility can vary by country, account and device, so confirm that the installed app is actually the Bot app before following Bot-specific advice.

The Grok Bot product page describes bots working on their own computers. In practical terms, the task can be handled in the bot's work environment and then returned to the user for review. A task thread on Android therefore should be evaluated by its result: what was requested, what work was performed, and what action, if any, happened on the local phone.

The xAI procurement example shows a business workflow with information gathering, options and review. That is useful context for Bot-style work, especially when the goal is research or process handling. It does not establish Android SIM calling or live incoming-call answering. If the task is “research vendors,” a bot environment may fit. If the task is “call this contact from my phone,” look for an Android dialer or phone-agent route.

Separate outgoing and incoming calls

Voice conversation, generating a number, placing an outgoing call and answering an incoming call are separate results. Grok Voice Mode lets the user speak with Grok. An outgoing call needs one resolved contact or one phone number and a supported calling route. Incoming answering needs a live call event, an allowed Android role or call surface, caller context and a visible way for the user to understand what is happening.

When a source says Grok can talk, read it as voice interaction unless it also names a phone-call route. When a source says a bot can complete tasks, check whether the task returned a result in the bot environment or performed a local Android action. When a developer page describes the API, read it as model access for an app or service. The API can help software reason; the Android phone still controls contacts, dialer access, microphone access, call log access and incoming-call permissions.

A practical outgoing-call check should identify the target before execution. The result should resolve one consenting non-emergency contact or one exact number, use a calling path the phone supports, and show the actual call state after the approved action runs. If the target is ambiguous, resolve the contact first. For incoming calls, look for specific support for answering a live Android call, not just voice chat or assistant conversation.

For the broader difference between service calling, Android dialer handoff and user-owned phone calls, AI Agent Phone Calls: MCP Calling Services vs Android Dialer Control explains the execution paths without tying the answer to one assistant brand. For general incoming-call surfaces such as screening, text calls and transcripts, Can AI Answer Phone Calls on Android? Screening, Text Calls, Transcripts, and FoneClaw covers the phone-platform side in more detail.

Check Grok as Android default assistant

Android default-assistant availability is a device-side question. A phone can offer one set of assistant choices while another phone offers a different set, depending on the installed app, app declarations, Android build, OEM behavior, region and account state. The reliable check happens in Android Settings on the exact device.

Open Settings and search for default apps, digital assistant or assistant app. On many phones the path is similar to Apps, Default apps, Digital assistant app. On others it may sit under Apps, Voice input, Assistant or a manufacturer-specific menu. If Grok appears, select it only when you want to test that entry point. If it does not appear, the phone is not offering that app as a default assistant choice in the current setup.

The assistant role controls invocation: what opens when you use a gesture, power button, voice trigger or assistant shortcut. It does not by itself authorize contacts, calls, notifications, accessibility actions or app control. After changing the default assistant, ask a harmless question first. Then test one bounded action and inspect what actually happened on the phone.

Also record how to change back before testing sensitive tasks. If you normally rely on Gemini, Google Assistant, Bixby or another assistant for daily phone commands, confirm the old assistant remains available in the same settings area. The goal is to learn what Grok can launch or handle on that phone while keeping your working setup recoverable.

Verify one bounded phone task

Before granting broader access or trusting a social claim, verify one bounded task. Use a known consenting non-emergency contact, keep the phone visible and avoid work-critical calls. If you want a no-call first test, ask only to identify or show the contact and explicitly say not to dial. If you want an actual outgoing call, confirm the target and authorize that call before execution.

1. Confirm the app. Check whether you are using Grok AI, Grok Bot, a browser session, an API-powered app or FoneClaw.
2. Confirm the result. Decide whether the goal is voice conversation, remote bot work, outgoing dialing, incoming answering or Android assistant invocation.
3. Check the route. Look for an official app feature, Android setting, dialer handoff or FoneClaw supported action.
4. Use one target. Choose one unambiguous consenting contact or one exact non-emergency number.
5. Inspect the phone state. A model answer is not proof that a call was placed; the dialer, call screen or app result should show what happened.
6. Retry after checking state. If the task blocks, inspect permissions, account status, model endpoint and visible phone state before repeating the request.

This kind of test is more useful than a broad prompt such as “control my phone.” It tells you whether the installed app can perform the specific result you care about. If the result is unavailable, choose another route before expanding permissions.

FoneClaw also exposes clearer delegated progress and results for supported tasks. That helps the user see whether the model response, permission step, contact lookup, dialer action or final visible result is the part that needs attention.

Use a Grok model inside FoneClaw

In FoneClaw, Grok can be used as a reasoning model when the user configures a compatible endpoint. The Grok app subscription and the Grok API developer service are separate product routes, so check the provider account, billing, API base URL, key and model ID before assuming one covers the other. For full setup steps, Connect an AI Model API to an Android Phone Agent in FoneClaw explains how to add and test a compatible model provider.

Once configured, the model helps interpret requests and plan the next step. FoneClaw handles the Android side through its supported tools, permission checks, approval behavior and visible results. Model intelligence helps decide what should happen, while FoneClaw performs the supported phone action through the Android route available on the device.

For an outgoing call, the current FoneClaw route is an actual approved call flow. The request must resolve to exactly one phone number or one contact name. If several contacts match, FoneClaw resolves the ambiguity first. After the user confirms the target and authorizes the outgoing call, FoneClaw opens the visible system dialer, inspects the screen, taps the call button, and then the user can observe the correct recipient and call state.

Use a clear request such as: Call Jordan from my contacts. If you only want to check the contact, say: Find Jordan in my contacts and show the matching contact, but do not dial. Those are different tasks. The first is an approved outgoing call. The second is a no-call lookup. Do not use emergency numbers, unknown contacts or ambiguous names for the first call test.

Current official Grok AI and Grok Bot materials do not establish automatic Android SIM incoming-call answering. FoneClaw's supported Android value here is concrete: compatible model reasoning, dedicated custom-model management with direct editing, clearer delegated progress, permission-aware execution and visible outcomes for supported actions. Current capability areas are summarized on FoneClaw Features, and Android installation is available from FoneClaw Download.

Choose the setup that matches the result

Choose by outcome. Use Grok AI when you want chat, voice conversation, media generation or image understanding inside Grok. Use Grok Bot when you want the Bot task experience and it is available for your account and device. Use the Grok API when you are configuring a developer model endpoint. Use FoneClaw when the goal is a supported Android action powered by a configured model and verified on the phone.

• Conversation: Open Grok AI and use chat or voice.
• Bot work: Use Grok Bot for task threads and review the result it returns.
• Default assistant: Check Android Settings and test the assistant entry point on the exact phone.
• No-call contact check: Ask to identify or show one contact and explicitly prohibit dialing.
• Outgoing call: Use one resolved consenting contact or exact number, confirm the target, authorize the call and observe the call state.
• Incoming call: Look for documented incoming-call support before expecting automatic answering.
• FoneClaw route: Configure a compatible model, choose a supported Android action and verify the result.

The practical answer is not one universal Grok claim. Grok can be a conversation app, bot app or model provider. FoneClaw can use a compatible model to help with supported Android actions. The right setup is the one that matches the result you want and shows enough phone state for you to verify it.
