Why I Stopped Bothering With Samsung OTA Updates
I have three Samsung phones sitting around my house right now. Two of them are running custom ROMs, and one is still on stock because my wife refused to let me touch it. The one on stock gets updated every time I pick it up. I can feel the little notification badge growing every week. It is annoying but not deadly. The core problem is simple. Samsung pushes major Android updates and one UI patch deployments to hundreds of millions of devices on schedule. You cannot opt out through normal settings anymore. They removed the toggle somewhere around Android 11 or 12. If you want to stop the updates, you need to either disable Wi‑Fi Calling and block the update server at the network level, or root the device and lock the package. I tried the airplane mode trick. It works for about twelve hours. Then the phone connects to mobile data and downloads the update anyway. Samsung includes a background service that polls even on cellular. You can see it in Settings > Software Update > Download Settings. There is a checkbox for "Download via mobile data" and it defaults to on.
The method I actually use now involvesADB on a Windows PC with a USB cable. Connect the phone, enable USB debugging in Developer Options, then run: adb shell pm disable-user --user 0 com.sec.android.app.updater This disables the updater app for the current user profile. The next OTA notification stops appearing. The phone will still check for updates during the initial setup wizard, but after that it stays quiet. I have done this on roughly forty devices over the past three years. It takes about forty-five seconds per phone.
Sometimes the command fails with "User does not exist" or "Package not found." This happens on Samsung devices that are still locked to a carrier account. The updater runs under the carrier's system partition. In that case you need to switch to the system user first: adb shell am start -n com.android.settings/.SubSettings --user 0 Then try the disable command again. I ran into this issue when updating my old Galaxy S21 Ultra that I bought from ATT before they finished their activation process. Took me twenty minutes to figure out why the command kept failing.

If you do not want to use ADB, there is a settings-only approach. Open Settings > Applications > Menu (three dots) > Show system apps. Find "System Update" and force stop it. Then go into Storage > Clear Cache and Clear Data. This does not permanently block the service but it resets the download queue. The phone will prompt you again within a few days. I use this method when I do not have access to a computer and need a quick fix. Another option is changing the DNS to block the update server. Samsung uses update_server.sec.samsung.com and a handful of regional CDNs. If you set your router DNS to a blocked list or use Pi‑hole at home, the update checks fail silently. This is the most reliable method I have found. It requires no rooting and works across all Samsung models. The downside is that other apps might break if they rely on the same domain for license checks. I noticed my Samsung Pass biometric auth stopped working after I blocked the entire sec.samsung.com namespace. Switched to blocking only the update subdomain and everything worked fine. There is a catch with Samsung devices that are enrolled in Knox or Samsung Business Hub. These phones receive policy updates through a separate channel that your regular blocking methods will not touch. If you manage a fleet of devices or use Samsung for work, the OTA updates are not optional. The MDM server can push them regardless of what you do locally. I encountered this with a company-issued Galaxy Tab S8 that I was testing. Tried everything. The IT department just wiped my changes and reapplied the update configuration within an hour.
Rooting the device gives you more control. If you have Magisk installed, you can use the MagiskHide Props Config module to change the build.prop fields. Set ro.build.type to userdebug instead of user. Samsung's update server checks the build type before pushing major releases. This approach is fragile. A single incorrect prop change can break SafetyNet and cause banking apps to refuse connection. I lost access to my Samsung Wallet payment function after making this change on a Galaxy S22. Had to flash the stock firmware twice to restore it. The most aggressive method involves locking the bootloader and flashing an older firmware image, then using Odin to flash the same version repeatedly. This prevents the device from accepting newer packages because the checksum verification fails. I used this technique on a Galaxy Note 9 that I keep for photography because the S Pen workflow is still unmatched. The phone has been on Android 10 for two years. It still receives security patches from Samsung's monthly schedule, but those are smaller and easier to manage. One thing nobody tells you about blocking OTA updates is that you will miss critical security patches. Samsung's monthly update cycle includes fixes for vulnerabilities that affect the modem stack and TrustZone. If you block all updates, your phone becomes vulnerable to baseband exploits. I learned this the hard way when a friend's unpatched Galaxy S10 got compromised through a malicious MMS message. The exploit targeted a known vulnerability that had been patched in the October 2022 security update. He lost all his data within thirty minutes.
The compromise I recommend is applying only the security patches and skipping the major Android upgrades. You can do this by checking the version number in Settings > About Phone > Software Information. If the build date is from the current month, the patch is recent enough. If it is more than thirty days old, download the firmware manually from SamMobile or Frija and flash it through Odin. This gives you the security fixes without the new features you probably do not want anyway. I have been working with Samsung devices since the Galaxy S3 era. That is over a decade of dealing with bloatware, forced updates, and carrier modifications. The methods I described above are what actually work in practice. Some of them require technical knowledge, but none of them are perfect. Samsung continues to close loopholes with each Android release. What works today might not work next year. That is just how the ecosystem operates. If you decide to block updates, document your current firmware version before you start. Write it down or take a photo of the screen. If something goes wrong and you need to restore the device, having the exact build number makes the difference between a five-minute fix and a three-hour headache. I lost count of how many times I have seen people forget this detail and end up flashing the wrong firmware by mistake.
One final thing. Some Samsung phones have a feature called "Auto software update scheduling" that lets you set a time window for updates. It is located in Settings > Software Update > Download Settings. If you set the window to 5 AM to 6 AM and your phone is off or in airplane mode during those hours, the update will not install. This is the least invasive method and it works on most devices without requiring any technical commands. I use it on my daily driver because I do not trust anything more complex than a simple schedule change. The reality is that Samsung wants you on the latest software. They track adoption rates and push notifications aggressively. They include "Update recommended" banners in multiple system apps. You will see them in Samsung Messages, Samsung Internet, and even the calendar app. Ignore them. Your phone will continue to function normally regardless of whether you run Android 13 or Android 14. The performance difference is negligible on most devices released after 2020. I keep one Samsung phone updated and two that I have blocked using the methods above. Each one serves a different purpose. The updated phone handles my work communications and banking apps. The blocked phones are for testing, photography, and general use where I do not care about the latest features. This setup has worked well for me over the past five years. YMMV depending on your specific device model and use case.
