Samsung Customization Service and Location: What to Disable

When you set up a high-end Galaxy device, Samsung presents you with a series of polished legal agreements that often blur the line between useful features and data collection. The core of this data harvesting is the Samsung Customization Service, a system designed to monitor your habits to provide "personalised" content. For many users, the most sensitive part of this profile is the samsung location privacy data, which tracks not just where you are, but where you live, work, and socialise, often in the background without clear indicators.

Managing your privacy on a Samsung device running One UI 6 (Android 14) or the newer One UI 7 (Android 15) requires a more surgical approach than on a stock Google Pixel. While a Pixel primarily deals with Google’s tracking, Samsung users face a "double tap" of data collection: once by Google and once by Samsung’s own ecosystem. This guide provides the exact steps to untangle these services, shut down unnecessary location pipelines, and reclaim your digital footprint without breaking essential phone functionality.

Customization Service explained

The Samsung Customization Service is a system-level background process that creates a detailed persona of who you are based on how you use your phone. It doesn't just look at one app; it synthesises data from your call history, message metadata, search queries, and, most crucially, your GPS movements. On Samsung One UI 6, this service is marketed as a way to make your phone "smarter"—for example, suggesting your favorite music when you plug in headphones or showing weather alerts for your exact location. However, for those concerned with samsung location privacy, the trade-off is often too high.

Technically, this service acts as a bridge between your hardware and Samsung's cloud servers. It records your frequent locations to build a map of your "places of interest." If you have ever wondered how your phone knows you are "at home" without you telling it, this service is likely the culprit. Unlike standard app permissions which you grant one-by-one, the Customization Service often gets blanket approval during the initial device setup when users tap "Agree to all." It is important to note that this is distinct from Google's location history; Samsung maintains its own independent database of your movements.

On the latest Android 15 builds (One UI 7), Samsung has slightly rebranded how these toggles look, but the underlying mechanism remains the same. The service uses a combination of GPS, Wi-Fi scanning, and Bluetooth beacons to pinpoint your location even when you are indoors. By disabling this specific service, you aren't just stopping ads; you are cutting off one of the most proactive data-collection pipelines on the device. While Xiaomi’s HyperOS has a similar "Personalised recommendations" toggle and Pixels use "Personalize using app data," Samsung’s implementation is more deeply integrated into the system framework.

Samsung account location data

Your Samsung Account is the central hub where all your device data is synchronised. Even if you haven't opened a specific Samsung app in weeks, your account may still be receiving location packets. This is particularly relevant if you use "Find My Mobile" or "SmartThings." While these features provide security, they also mean that your Samsung account location data is being updated whenever the device moves significantly. Historically, Samsung's privacy policy allows them to retain some of this data for analytics unless you explicitly opt out of the marketing and personalisation segments of the account agreement.

One UI location settings are often buried three or four layers deep within the Account menu, making them easy to miss. On Android 13 and 14, Samsung introduced a more centralised "Security and Privacy" dashboard, but it still prioritises Google’s settings over Samsung’s proprietary account tracking. The data stored in your Samsung account is used to synchronise your "Points of Interest" across multiple Galaxy devices, such as a tablet or a Galaxy Watch. If you visit a location frequently, it is tagged in your Samsung profile, which can then be shared with partner services if certain marketing toggles are left active.

For users who want to transition to a more private setup, it is vital to understand that your Samsung account is a separate entity from your Google account. You might have "Location History" turned off in your Google settings (Settings > Google > Manage your Google Account > Data & privacy), but that does not automatically stop Samsung from recording your coordinates. You must treat the Samsung account as a second, independent layer of tracking that requires its own set of restrictions. This is a common point of confusion for those switching from a Pixel or a Xiaomi device, where there is usually only one primary manufacturer account to manage.

Disabling each pipeline

To fully secure your device, you need to navigate through several distinct menus. To disable the primary Customization Service, follow these steps: 1. Open Settings and tap on your Name/Samsung Account at the top. 2. Scroll down and select "Customization Service." 3. Toggle off "Customise this phone" and "Data management." 4. Inside "Data management," specifically ensure "Location" is toggled off. This stops the phone from uploading your GPS logs to Samsung's personalisation servers. On older devices running Android 13, this may be located under Settings > Privacy > Customization Service.

Next, we must address the persistent background location scanning that Samsung uses for its ecosystem. Follow this path: 1. Go to Settings > Security and privacy > Privacy. 2. Tap on "Other privacy settings" (this is where Samsung hides the "Samsung Privacy" portal). 3. Select "Samsung Privacy" which will open a web-based interface within the settings app. 4. Go to the "Delete data" tab or "Manage data" and look for "Location." Here you can request the deletion of all previously harvested location data associated with your Samsung account. This is a crucial step that many guides overlook; stopping future collection doesn't remove the history already on their servers.

Finally, you should limit how individual Samsung apps access your location in the background. Go to Settings > Apps > Tap the filter icon and toggle on "Show system apps." Search for "Samsung Checkout," "Samsung Visit In," and "Samsung Shop." For each of these, go to Permissions > Location and select "Don't allow." "Samsung Visit In" is particularly aggressive, as its sole purpose is to send you notifications based on which shops or venues you walk past. Disabling this significantly improves your samsung location privacy without affecting your ability to use Google Maps or other navigation tools.

Bixby and location

Bixby, Samsung’s voice assistant, is often overlooked in privacy audits, but it is one of the most location-hungry components of One UI. To provide "contextual" answers—like telling you the weather at your current spot or setting reminders when you arrive at a specific grocery store—Bixby requires constant access to your GPS. Even if you don't use the Bixby voice trigger, the underlying "Bixby Vision" and "Bixby Routines" (now called Modes and Routines) might be pinging your location in the background. In One UI 6, "Modes and Routines" is a powerful tool, but every "Location-based routine" you create adds another trigger that keeps the GPS radio active.

To restrict Bixby’s access: 1. Open the Bixby app and tap the Settings (cog) icon. 2. Look for "Privacy" and then "Personalized Bixby." 3. Toggle this off to prevent Bixby from learning your home and work locations. If you use "Modes and Routines," review your active routines: 1. Go to Settings > Modes and Routines. 2. Check each routine to see if it uses "Place" as a trigger. 3. If you value privacy over convenience, replace "Place" triggers with "Wi-Fi network" triggers (e.g., "When connected to Home Wi-Fi") which is much more battery-efficient and slightly more private than constant GPS polling.

Users on Android 15 will notice that Bixby is becoming more integrated with "Galaxy AI." This new layer of artificial intelligence often requests "Online processing" for more accurate results. Providing location data to these AI models allows Samsung to refine their local search algorithms using your movement data. If you are not using Bixby as your primary assistant, it is best to go to Settings > Apps > Bixby Voice > Permissions > Location and select "Don't allow" or "Ask every time." This ensures that the assistant only knows where you are when you explicitly interact with it, rather than tracking you silently as you move through the city.

Dual disable: Samsung + Google

The "dual tracking" nature of Samsung phones means that even if you lock down every Samsung-specific setting, Google is still monitoring you via Google Play Services. To achieve true samsung location privacy, you must coordinate your settings across both companies. On a Google Pixel, you only have one master switch. On a Samsung, you have to verify two. First, address the Google side: 1. Go to Settings > Location > Location Services. 2. Tap "Google Location Accuracy" and turn it off. While this may slightly slow down your initial GPS lock, it prevents your phone from sending nearby Wi-Fi and cell tower data back to Google to help them map the world.

Next, you must address the "Wi-Fi and Bluetooth Scanning" settings which are often the biggest leaks of location privacy. In One UI 6 and 7: 1. Settings > Location > Location Services. 2. Toggle off both "Wi-Fi scanning" and "Bluetooth scanning." By default, these remain on even if you turn off your main Wi-Fi or Bluetooth toggles. They allow the device to "see" your surroundings even when you think the radios are off. This is a common tactic used by both Samsung and Google to maintain a location fix without the high battery drain of full GPS. Turning these off is a major win for privacy, as it stops the device from constantly broadcasting its presence to nearby beacons.

Compare this to Xiaomi’s HyperOS, where these settings are often buried under "Interconnectivity" or "Location" with less transparency. Samsung at least puts these under a dedicated "Location Services" menu. It is also worth checking "Google Location History" (now called "Timeline" in Google Maps) from this same menu. Samsung provides a shortcut here, but the data is stored in your Google Account. If you want to be completely "off the grid," you need to ensure that Google’s Timeline is paused AND Samsung’s Customization Service represents an empty profile. Only by disabling both can you prevent your movements from being tracked by two separate advertising giants simultaneously.

Verifying with the dashboard

Once you have finished the configuration, it is vital to verify that no "rogue" apps or services are still accessing your coordinates. Android 13, 14, and 15 all include a "Privacy Dashboard" which is the most powerful tool for this audit. On your Samsung: 1. Go to Settings > Security and privacy > Privacy. 2. Tap on "Privacy Dashboard" or "View all permissions." 3. Select "Location." You will see a 24-hour timeline of every single app that has requested your location. If you see "Samsung Account," "Google Play Services," or "Customization Service" appearing frequently in this list after you have followed the steps above, you may need to go back and check if a specific "Mode" or "Routine" is overriding your settings.

Another specific Samsung trick is the "Permission manager." Navigate to Settings > Security and privacy > Privacy > Permission manager > Location. Here, scroll down to the bottom and select "See all apps with this permission." Check the "Allowed all the time" category. This is the most "dangerous" category for privacy, as apps here can track you without any notification. Ideally, this list should be empty, or contain only a trusted emergency app. Most apps, including Google Maps and Weather, should be set to "Allow only while using the app." One UI 7 (Android 15) also introduces more prominent "Privacy Indicators"—the little green dot in the top right corner of your screen—which tells you in real-time if an app is currently accessing your GPS.

As we look toward future updates like One UI 7.1, we expect Samsung to integrate more "on-device" AI processing. This could theoretically improve privacy by keeping your location data on the phone rather than the cloud. However, the current reality remains: the more services you have active, the larger your digital footprint. By systematically disabling the Customization Service and tightening your Samsung account settings today, you are creating a "private by design" environment that will handle future updates more securely. Managing your privacy isn't a one-time task, but with these settings locked down, you've removed the most systemic tracking vectors on your Galaxy device.
