There is no single “on-device AI” switch for every Android phone. Processing is decided feature by feature. Identify the exact task, find out which app or system service provides it, read the manufacturer’s documentation, and then (if practical) test that task with Wi‑Fi and mobile data disabled. On Android 14 and later, Android AICore in Settings > Google profile > All services > Privacy and security > System services is evidence that a local-AI service is installed, but it does not prove that every AI feature on the phone runs locally. Samsung Galaxy phones provide a separate Settings > Galaxy AI > Process data only on device control, although enabling it can disable or change some features.
What “on-device AI” means on Android
On-device (or local) processing means the phone’s processor handles the AI operation instead of sending the relevant input to a remote server for that operation. A cloud feature uploads some or all of the input, receives a result from an online service, or depends on a live connection. A mixed feature can perform one stage locally and another in the cloud.

The distinction belongs to a specific task, not to the phone’s marketing name. A phone can summarize a recording locally, send an image-edit request to a server, and use a third feature that chooses between both routes. The presence of an assistant app, the word “AI” in a feature name, “Gemini” branding, or an AICore service therefore cannot establish a phone-wide processing policy.
For privacy and reliability, ask a narrow question such as “Does this Recorder summary run without a network?” rather than “Does my phone’s AI run on-device?” The answer can change with the model, Android or manufacturer software version, region, language, account type, and the particular feature version.

Start with the exact AI task
Write down what you want to check before opening Settings. Examples include a Recorder transcription or summary, a keyboard smart-reply suggestion, live translation, an assistant response, an image editor, scam detection, or automatic formatting in a document. Different tasks may be supplied by Android system components, the phone maker, a separate app, or a web-based service.
Identify the provider
- Android system service: Android AICore can supply local generative-AI functions on supported Android 14-and-later devices.
- Manufacturer feature: Samsung’s Galaxy AI has its own documentation and a device-level restriction for server processing.
- App feature: A recorder, keyboard, gallery, or messaging app may document its own processing route independently of Android’s system settings.
- Web or assistant experience: An online assistant can remain cloud-based even when local AI components are installed.
Open the feature’s help, information, or privacy page and note the exact name and version. If the feature is inside an app, check that app’s settings and support page as well as the phone’s system settings.
Check for Android AICore
Google describes AICore as an Android system service that runs generative-AI features on device hardware and can run Gemini Nano. Google says AICore is available on Android 14 and later, but support still varies by device and manufacturer. Its presence is a useful clue, not a universal certificate that all AI work is local. See Google’s current documentation for the service and its examples: About Android AICore.

- Open Settings.
- Tap your Google profile (the account area at the top of Settings on supported builds).
- Choose All services.

- Tap System services and look for Android AICore.
Labels and their location can differ by manufacturer and software release. If you cannot find the entry, that does not prove the phone lacks all local AI: the model may use a different implementation, the service may be hidden, or the feature may not be supported. Conversely, finding AICore only proves that the service is present; you must still check whether your chosen task uses it.
What AICore can and cannot tell you
Google’s Android Help lists advanced proofreading, automatic speech recognition, scam detection, smart replies, recorded-audio summaries, and translation as common AICore-powered examples. Google says note summarisation and smart replies happen locally and that those examples can work without a network connection. The list is not a promise that every model supports every item, and a feature’s language or hardware requirements may exclude your phone. Confirm the precise function in its current help page.

Check Samsung Galaxy AI settings
Samsung documents Galaxy AI separately from Android AICore. On supported Galaxy phones, open Settings > Galaxy AI and look for Process data only on device. This is Samsung’s current U.S. support path; menus and availability can differ by model, software version, and country. Samsung’s feature guidance is at Use features with Galaxy AI on your Galaxy phone and tablet.
Interpret the Samsung control
Turning on Process data only on device restricts Galaxy AI from using Samsung’s servers where the control applies. Samsung also warns that some AI functions may be limited or unavailable when server access is blocked. Treat the switch as a privacy restriction with a functionality trade-off, not as proof that every Galaxy feature has an on-device implementation.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Samsung’s current U.S. examples classify translation, ambient wallpapers, and certain Google Messages functions as on-device, while auto formatting, automatic summarising, auto corrections, and image editing are listed as cloud-based examples. Those classifications are tied to Samsung’s stated model and software context; another Galaxy model, region, language, or later release may differ. Check the support page for the exact feature you intend to use.
Read feature-specific documentation
After identifying the provider, search its support material for the exact task rather than a general “AI” page. Look for terms such as on-device, offline, cloud processing, server, or requires an internet connection. Documentation may describe a feature as local, cloud-based, or capable of using either route.
- Record the supported phone models, Android or One UI version, language, and region.
- Check whether the feature needs an initial download, account sign-in, or a recent model update.
- Note whether only the inference step is local while setup, updates, syncing, backups, or optional enhancements use a network.
- Read what changes when a local-only control is enabled; restricting servers can remove higher-quality or more advanced functions.
Google describes Gemini Nano as handling some sensitive use cases on-device while also explaining that Gemini data can be processed in the cloud or on the device depending on the task. “Gemini” in a feature name therefore does not settle the question. Google’s overview is available in Android is reimagining your phone with Gemini.

Use an offline test as corroboration
A controlled offline trial is the most practical way to check whether the particular task can complete without a live connection. It is supporting evidence, not a forensic guarantee about every data flow.
Offline test procedure
- Choose a harmless test input that does not contain passwords, confidential work, medical details, or another person’s private information.
- Let the feature load normally while connected, and note whether it offers an explicit offline or on-device mode.
- Turn off Wi‑Fi and mobile data. Airplane mode is a simple way to disconnect, but verify that Bluetooth or other required links are not part of the feature.
- Run the same task again without changing the input. Wait long enough for a local operation to finish; do not repeatedly tap a control that may queue a request.
- Record the result and any message. A completed result supports the conclusion that this task can work under those conditions. A prompt to reconnect indicates that the task, configuration, or current model needs a network.
- Reconnect before checking for updates, synchronising results, or using other features.
What the result proves
If a summary, reply, translation, or other operation succeeds with both network radios disabled, the tested operation can run without a live connection in that configuration. It does not prove that the feature never sends data when connected, that a different input follows the same route, or that installation, updates, telemetry, account services, or related functions are offline. Google’s AICore documentation describes offline behavior for supported tasks; it is not a universal test for every Android phone or app.
Compare local, cloud, and mixed behavior
When documentation offers more than one processing route, compare the practical consequences rather than relying on a badge or brand name.
| Question | On-device route | Cloud route | Mixed route |
|---|---|---|---|
| Where is the main AI computation performed? | On the phone’s processor or neural hardware | On a remote provider’s servers | Some stages on the phone, others remotely |
| Does the task work with Wi‑Fi and mobile data off? | Often, if the model and required files are installed | Usually no | Only the local portion may work; a server-dependent stage can fail |
| What input is processed? | The selected input remains on the device for that operation | The required input is sent to the service | Only the stages documented as local avoid server processing |
| Can a setting restrict network processing? | Sometimes; Android and manufacturer controls differ | Often not without losing the feature | A restriction may preserve basic functions while removing advanced ones |
| Typical trade-off | Greater offline availability and local handling, with hardware, storage, speed, or quality limits | More compute and potentially broader features, but a connection and provider data handling are required | Flexible behavior, but the exact boundary must be documented for each task |
Use the table as a checklist for one feature at a time. If a source does not state a value, do not infer it from another feature on the same phone.
Do not generalise from Gemini or a phone’s AI branding
Gemini is a family of experiences rather than a guarantee of local execution. Google’s materials distinguish Gemini Nano, which supports selected on-device use cases, from tasks that use cloud processing. An assistant response, a writing tool, and a recorder summary can therefore have different network requirements even when they display the same brand.

The same caution applies to “Galaxy AI,” “AI-powered,” and similar labels. Branding identifies a product family, not the route used for every operation. The relevant evidence is the feature’s current support page, the applicable setting, and (where safe) the offline behavior of that task.

Older rollout announcements illustrate how local support can depend on a specific model and software stage; they are not current compatibility lists.
Pixel 8 Pro announcement from December 6, 2023
Google announced on December 6, 2023 that Gemini Nano powered Recorder summarisation and Smart Reply in Gboard on the Pixel 8 Pro. The announcement said Recorder summaries were available offline and described Smart Reply as a developer preview at that time. See Pixel 8 Pro — the first smartphone with AI built in, plus more AI updates coming to the Pixel portfolio.
Pixel 8 and Pixel 8a announcement from June 11, 2024
Google’s June 11, 2024 feature announcement said Gemini Nano was available on Pixel 8 and Pixel 8a as a developer option and that Recorder summarisation ran on-device. Its footnote limited detailed summaries to the Pixel 8 Pro and Pixel 8/8a through Developer options in English. Those model, language, and developer-option limits belonged to that dated rollout. Do not use the announcement as proof that a current phone, language, or feature version has identical support. The announcement is at June Feature Drop: New features and upgrades for the Pixel portfolio.
Check model, software, language, and region requirements
Local models require enough compatible hardware, storage, and software support. A feature can be local on one edition and cloud-assisted on another, or available only in selected languages. Before testing, verify:
- Exact model and storage edition, not merely the product family name.
- Android version and manufacturer interface version.
- Country or region of the phone and account.
- Language selected for the feature and the language of the input.
- Whether an optional developer setting, downloadable model, or app update is required.
- Whether the feature is available to personal users, managed users, or a limited preview group.
Changing language, installing an update, or switching accounts can change the available route. Re-run the documentation check after a major software update instead of assuming an earlier result remains valid.
Managed Android phones have an additional control layer
Work-managed devices may be subject to administrator policies that consumer phones do not show. Google’s Android Enterprise documentation distinguishes on-device generative-AI experiences from native apps, web-based experiences, screen-driven experiences, and agent-based experiences. It also documents an administrator control to disable the Android AICore system service. See Gemini for work on Android.
If AICore is missing or disabled on a managed phone, contact the administrator rather than sideloading a replacement. A policy can block a local system component while still allowing a separate cloud app, so check the work profile’s rules and the individual app’s documentation.

The feature immediately asks for a connection
The task may be cloud-only, may need a server for one stage, or may not have downloaded its local model. Reconnect, check the feature’s support page, and look for a download or on-device setting. Do not conclude that all AI on the phone is cloud-based from one failure.
The feature worked once but not later
The first run may have used cached output, while a later request required a server. A model update, language change, account change, or battery-saving policy can also alter behavior. Repeat the test with a new harmless input and record the software version.
A local-only switch removes features
This is expected when a feature depends on server processing. On Galaxy devices, Samsung explicitly warns that restricting server access can limit some Galaxy AI functions. Decide whether the privacy benefit outweighs the lost capability, and document which functions disappear before relying on the setting.
The menu path does not exist
Settings labels vary by model and release. Search Settings for “AICore,” “Galaxy AI,” or “process data,” then use the manufacturer’s current support page for the exact model. A missing menu is not proof that processing is cloud-only or that no local component exists.
Recommended Free Tools
A practical privacy checklist
- Name the precise AI operation and the app that launches it.
- Check the current feature documentation for local, cloud, or mixed processing.
- Inspect Android AICore or the manufacturer’s equivalent service where applicable.
- Enable a documented local-only control if it fits your needs, noting any features it disables.
- Test the exact operation offline with non-sensitive input.
- Keep separate the result of that test from broader claims about telemetry, syncing, updates, backups, or other tasks.
- Recheck after changing model, language, region, account, or major software version.
This process gives you a defensible answer for the feature you actually use without assuming that an entire phone follows one processing route.
