Inscription "AD" in the corner of the screen, pop-up banners when unlocking or advertising notifications from unknown applications - every third Android user faces these problems. In 2026, aggressive advertising has become even more sophisticated: it disguises itself as system alerts, is built into the quick settings menu, and even appears on the lock screen. Moreover, the reason for this is not always viruses - often advertising is shown by legitimate applications (including those pre-installed by the manufacturer) or itself Android after updates.

In this article we will look at all possible sources of AD advertising on Android smartphones and show how to get rid of it get rid of: from basic settings to advanced methods using ADB and alternative firmware. It is important to understand that there is no universal solution - it all depends on the phone model, OS version and type of advertising. For example, on Xiaomi and Redmi services msa and Mi Pushare often to blame, and on Samsung built-in applications like Samsung Free or Bixby. We will consider each case separately.

We warn you in advance: some methods require disabling system applications or use ADB - this can lead to unstable operation of the phone. If you are not sure of your actions, it is better to contact a specialist. Also remember that after resetting the settings or updating the OS, advertising may return - so we will give recommendations on how to prevent it from appearing again.

1. How to determine the source of AD advertising on Android

Before removing ads, you need to understand which application or service shows it. In 80% of cases, the fault is:

  • ๐Ÿ“ฑ Pre-installed applications manufacturer (for example, Mi Browser, Samsung Internet, Huawei AppGallery).
  • ๐Ÿ”„ Push notification services (Mi Push Service, Huawei Push Kit, OPPO Push).
  • ๐Ÿฆ  Hidden advertising applicationsinstalled along with pirated content or โ€œfreeโ€ utilities.
  • ๐Ÿ“Š System services (for example, Android System WebView or Google Play Services in older versions).
  • ๐ŸŽฎ Games and applications with aggressive monetization (for example, AliExpress, Likee, ShareIt).

To figure out the culprit:

  1. When advertising appears, quickly pull down the notification bar - sometimes the name of the application is displayed there.
  2. Go to Settings โ†’ Applications โ†’ All applications and sort by date of last use. Advertising applications often appear at the top of the list.
  3. Use task manager: click on the โ€œrecent applicationsโ€ icon (square or swipe up) and see which application was active when the ad was displayed.
  4. Install App Inspector (available in Google Play) - it shows which application is currently displaying an overlay (pop-up window).

If advertising appears even without running applications (for example, on the lock screen), either system services or a virus are to blame. In this case, only deep cleaning or resetting the settings will help. Read about how to do this safely in the next section.

2. Basic methods for removing AD ads without root access

Let's start with the simplest methods that do not require special knowledge. They will help in 60โ€“70% of cases, especially if the advertisement appeared after installing a new application.

2.1. Disabling advertising notifications

Many applications show advertisements through push notifications. To turn them off:

  4. For reliability, also go to Settings โ†’ Applications โ†’ [application name] โ†’ Notifications and disable all permissions.

2.2 Limiting the background for suspicious applications

Some apps show ads even when you're not using them. To stop this:

  1. Open Settings โ†’ Applications โ†’ All applications.
  2. Select a suspicious application (for example, Clean Master, ES File Explorer, Cheetah Mobile).
  3. Click Battery (or Battery Usage).
  4. Select Limit Background Activity or Optimize.
  5. Also disable autorun: Settings โ†’ Applications โ†’ [application] โ†’ Autorun.

  4. Open the command line (Windows) or terminal (macOS/Linux) in the folder with Platform Tools.
  5. Enter command:
    adb devices

    If the phone is detected, continue. If not, install the drivers.

  6. To uninstall the application, enter:
    adb shell pm uninstall --user 0 package name

    If none of the above helped, there are radical methods:

    • ๐Ÿ”„ Reset to factory settings - deletes all user data and applications.
    • ๐Ÿ“ฑ Installing custom firmware (for example, LineageOS, Pixel Experience) - completely replaces the system software.
    • ๐Ÿ› ๏ธ Obtaining root access and manually removing system applications.

    • ๐Ÿ” Install applications only from Google Play (avoid APKs from unknown sources).
    • โš™๏ธ Immediately disable unnecessary system applications (see section 3).

    6.2. Installing custom firmware (for advanced users)

    • ๐Ÿ”“ Unlocking the bootloader (bootloader).
    • ๐Ÿ“ฑ Installing custom recovery (TWRP).

    Incorrect installation of the firmware can lead to:

    - Brick (the phone does not turn on).

    - Loss of IMEI (does not work cellular communication).

    - Problems with the camera, sensors or charging.

    If you are not sure of your actions, it is better to contact a specialist or use safer methods (for example, resetting settings).

    6.3. Obtaining root access and manually removing ads

    root access gives full control over the system, but voids the warranty and may compromise security. If you still decide to get them:
