When you set up a Samsung account on your Galaxy phone, you agree to a long list of terms and permissions that you probably don’t read. And honestly, I don’t blame you. The excitement of setting up a new phone makes it easy to miss the fine print. But among those default options is something called Customization Service.
I recently came across it while reviewing my Samsung account, and it turns out this feature is essentially Samsung’s own data tracking tool. It collects information about how you use your phone and monetizes that data. What sounds like a simple personalization tool is actually designed to benefit Samsung far more than it benefits you.
What does Customization Service do, exactly?
That name is confusing for a reason
The name Customization Service doesn’t really raise any eyebrows, but it is Samsung’s built-in data profiling engine. It is enabled as soon as you create a Samsung account. In simple terms, it collects information about what apps you use, how often you use them, and what you search for on the internet.
Samsung uses this data to build a profile of you so it can customize ads, promotions, and recommendations across its apps and services. Of course, Samsung says this helps improve your experience. And sure, you’ll see relevant suggestions, hints, and reminders across apps like Weather, Samsung News, Samsung Wallet, Smart Things, Galaxy Store, and more.
But the main issue here is transparency. Most people have no idea this feature is even active, let alone what it is doing in the background. It’s buried in the privacy settings, and described in vague language that makes it sound like a simple personalization option. In reality, it’s closer to a targeted advertising tracker built right into One UI.
Another issue is that this data is not only used by Samsung. According to Samsung’s website, parts of your profile can be shared with third-party vendors. This makes Customization Service a real privacy concern.
It’s concerning how much data it collects
How much is too much?
Customization Service is a single toggle that grants Samsung nearly every meaningful permission on your Galaxy phone. If your phone can generate the data, chances are this service is tracking it. To give you an idea, here are a few things that Customization Service collects.
- Device information: This includes your custom settings, the devices you connect to, and the apps you have installed. It paints a full picture of how your phone is set up.
- Music and photos: Samsung can log the type of music you listen to, as well as the details about your photos, such as where and when they were taken.
- Contacts and communication: This service can access your contacts list, analyze call logs, and review your text message history. It does this to determine your closest relationships and who you interact with the most. In other words, it’s profiling your social life.
- Calendar data: It can read your calendar data and note special occasions, appointments, and events. This gives Samsung insight into your routines and personal milestones.
- Internet browsing: This covers everything you do on the internet. It lets Samsung collect your browsing history, search history, and even bookmarks.
- Location information: This allows Samsung to know your precise location at any time and can help the company see where you’ve been.
When you add it all together, Customization Service no longer seems like a convenience feature. It’s a full scale data collection system running in the background.
It’s easy to opt out and erase all the data
Trust me, you won’t miss it
If there’s one bit of good news in all of this, it’s that Samsung gives you a way out. Customization Service is enabled by default, but you can easily turn it off and even wipe the data it has already collected.
Head to Settings > Samsung account > Privacy and security > Customization Service. From there, you can disable the feature entirely. Before you do that, though, it’s a good idea to erase all the data Samsung has gathered about you.
Tap Erase personal data and choose Samsung privacy website. This will take you to your browser, where you’ll need to sign in with your account. Once you’re in, head to the Deletion tab, tap Select all, and hit Request deletion.
After you’ve erased your data, return to your phone’s settings and turn off Customization Service for good. I’ve had it turned off for a week, and honestly, I don’t miss it at all.
You Can Safely Disable or Uninstall These Pre-Installed Apps on Samsung Phones
You don’t need all the apps on your Galaxy phone.
Other privacy settings you shouldn’t ignore
They’re just as important
Customization Service is just a part of Samsung’s data collection ecosystem. There are a few more privacy settings that are worth a look.
For instance, you can prevent your Galaxy phone from collecting and sending diagnostic data to Samsung. If you use Galaxy AI, you can configure it to process all the data locally rather than sending information to Samsung’s servers. Finally, if you use Samsung apps like Bixby, Gallery, Calendar, and Galaxy Store, you need to review what permissions each of these apps has.
Samsung’s Customization Service is a reminder that convenience often comes at a cost. While it’s possible to use a Galaxy phone without a Samsung account, it’s far more practical to disable this feature and take control over what data gets shared. So, that’s what I’ve done.
