How to permanently disable automatic updating of Android 7 Nougat: 5 proven methods

Automatic Android 7 Nougat updates can be a real headache if you don't want to lose control of your device. The system downloads and installs new firmware versions without warning, which leads to unexpected reboots, loss of root access, or even incompatibility with important applications. This problem is especially relevant for owners of old smartphones, where new versions of the OS work slower or consume more resources.

In this article we will look at all the possible ways to disable automatic updates on Android 7.0/7.1 Nougat —from standard settings to advanced methods using ADB and root access. You will learn which methods are safe and which may void your warranty or damage your device. We will also consider alternative options if completely disabling updates is impossible.

Why Android 7 is forced to update and why it is dangerous

Smartphone manufacturers and Google are actively promoting a policy of regular updates, arguing for improved security and stability. However, for Android 7 Nougat (released in 2016), current patches often bring more problems than benefit:

• 🔋 Increasing battery load —new OS versions are optimized for modern processors, not old chipsets.
• 🐢 Slowdown —firmware for Nougat do not take into account the limited resources of devices from 2015–2017.
• 🔓 Loss of root access —after an update, superuser rights are often reset, and restoring them requires re-unlocking the bootloader.
• 🚫 Incompatibility with applications —some apps (for example, for system modification) stop working on new versions of the OS.

In addition, forced updates may interrupt important processesif the device reboots at an inopportune moment (for example, during a call or using a navigator). This is especially critical for smartphones used for industrial or medical purposes.

⚠️ Attention: On some devices (for example, Samsung Galaxy or Xiaomi), manufacturers block firmware rollback. If you update to Android 8+ and want to go back to Nougat, this may lead to the device being bricked.

Method 1: Disabling updates through standard settings

The simplest and safest method is to use the built-in ones system options. However, not all manufacturers provide full control over updates. The instructions may differ depending on the shell (MIUI, One UI, EMUI etc.), but the general algorithm is as follows:

1. Open Settings → About phone (or About tablet).
2. Find the item System update (may be called Software update, Update center).
3. Tap on the ⚙️ (settings) icon in top corner or find the option Auto-update.
4. Select Do not update automatically or Only through Wi-Fi (if there is no complete shutdown).

On some devices (for example, Huawei or Honor), you may need to additionally disable the option Downloading updates in the background. If there is no such item, proceed to the next method.

⚠️ Attention: On devices with Android One (for example, Nokia or Motorola) even after disabling auto-updates, the system can forcefully install critical security patches. This is due to Google's policy on supporting devices in the app. Android Enterprise.

Method 2: Blocking updates through data restrictions

If in There is no option to completely disable the settings; you can prevent updates from downloading by limiting the system's access to the Internet. This method works on all devices, but requires manual control:

• 📵 For mobile data:
  1. Go to Settings → Wireless networks → Mobile network → Data transfer.
  2. Find the application Software update (or Software Update) and turn off mobile traffic for it.

This method does not block updates completely, but it makes downloading them much more difficult. The system will only try to update when connected to Wi-Fi, and even then, not in the background. However, some manufacturers (for example, Samsung) bypass this limitation through system services.

Method 3: Disabling update services via ADB (without root)

For advanced users ready to work c Android Debug Bridge (ADB), there is a way to disable system services responsible for updates. This does not require root access, but you need to enable USB debugging and install ADB tools on your computer.

Step-by-step guide:

1. Activate Developer mode:

   Settings → About phone → Build number (tap 7 times)

2. Enable USB debugging in Settings → For developers.
3. Connect the device to the PC and execute in the terminal:

   adb shell pm disable-user --user 0 com.android.updater
   adb shell pm disable-user --user 0 com.manufacturer.updater

   Replace manufacturer with the brand of your device (for example, samsung, xiaomi).

After executing these commands, the update service will be deactivated until the next reboot. To disable it permanently, add tasks to startup through applications like MacroDroid or Tasker.

⚠️ Attention: On some firmware (for example, ColorOS from Oppo/Realme), disabling system packages via ADB may cause other services to fail, such as Google Play Services. Before executing commands, make a backup copy of your data.

Method 4: Uninstalling updates via root access

If your device has root access, you can completely delete the update files and block re-downloading them. This method is the most radical and effective, but requires caution:

1. Install a file manager with root support (for example, Root Explorer or Solid Explorer).
2. Go to the folder /cache/ and delete the file update.zip (or folder fota).
3. Open the folder /system/app/ or /system/priv-app/ and delete (or rename) the files:
   • Updater.apk
   • Updater.odex
   • SoftwareUpdate.apk (for Samsung)

chmod 555 /cache

After these steps, the system will no longer be able to download and install updates. However, be prepared for the fact that some functions (for example, security check via Google Play Protect) may not work correctly.

Method 5: Blocking updates through the host file (for experienced ones)

This method involves editing file hoststo block access to update servers. It works without root, but requires re-application after a reboot or reset.

Instructions:

1. Download an application for editing the host file (for example, Hosts Editor or AdAway).
2. Add to the file /system/etc/hosts the following lines:

   127.0.0.1 android.clients.google.com
   127.0.0.1 update.googleapis.com
   127.0.0.1 manufacturer.com (for example, fota-cloud-dn.ospserver.net for Samsung)

3. Save changes and reboot device.

This method blocks calls to update servers at the DNS level, but does not guarantee 100% protection - manufacturers can use backup addresses. It can also disrupt the operation of other Google services (for example, Play Market or Gmail).

What to do if the update has already been downloaded

If the system has downloaded the update file, but has not yet installed it, you can remove it manually. Act quickly - some devices install updates automatically the next time you reboot.

• 📁 For most devices:
  1. Go to Settings → Storage → Files.
  2. Find the folder Download or cache.
  3. Delete files with names like update.zip, OTA.zip or bluetooth_firmware_update.
