How to Fix Unknown Apps Keep Installing Automatically on Android

Quick Tips
  • Open Settings > Apps > three-dot icon > Special access > Install unknown apps > Deny all.
  • Go to Google Play Store > profile icon > Manage apps & device > Sync apps to devices > disable sync for the relevant device.
  • Open Settings > Apps > the relevant app > Appear on top > turn off Allow permission toggle.

Basic Fixes:

  • Use browsers with ad-blocks: Certain Android browsers come with native ad-blocking support that can help keep ads at bay. This can also decrease the chances of you accidentally tapping on an ad and installing an unknown app on your Android device.
  • Double-check apps before installing: Most free apps have ad walls blocking access to certain features. When you click on them, your phone might start an automatic app installation. So, ensure the apps you install don’t have such features.
  • Set up Family Link restrictions: The Family Link app allows you to restrict the download of apps depending on their age rating on your child’s phone. Additionally, the app installation must be approved by the parent’s phone, eliminating accidental app downloads.

Fix 1: Disable Install Unknown Apps

As a safety feature, your Android phone allows you to restrict downloads of apps from unknown sources. You can still install new apps from official sources, like the Google Play Store, but app downloads from other unknown sources will be restricted. This can help curb unknown app downloads. Here’s how.

Step 1: Open Settings and tap on Apps.

Step 2: Tap the three-dot icon at the top-right corner. Tap on Special access.

Step 3: Tap on Install unknown apps. Here, tap on Deny all and ensure all toggles are turned off.

Fix 2: Disable Sync Apps to Devices in Play Store

When you connect other devices running on the same Google account with your Android phone, it might automatically sync the device data with your phone. This can cause unknown apps to be installed unprompted. To stop this, disable the relevant setting in the Google Play Store using the below steps.

Step 1: Open Google Play Store → your profile iconManage apps and device.

Step 2: Tap on Sync apps to devices and disable sync for the relevant device.

Fix 3: Turn off Lock Screen Ads

Certain device manufacturers allow ads from affiliated services on your device’s lock screen. This can increase your chances of accidentally installing an unknown app via an ad. To prevent this, disable ads from your device’s lock screen. Here’s how.

Step 1: Open Settings and tap on Wallpaper and style. Tap Change wallpapers.

Step 2: Tap on Wallpaper services and select None.

Fix 4: Switch to Official Apps

Step 1: Open Settings and tap on Apps. Tap on Choose default apps.

Step 2: Tap on the relevant app and change the default app.

Step 1: Open SettingsApps the relevant app. Tap on Appear on top.

  1. Yes, people may not be closing the advertisement. But I think the evil advertisers are actually altering the so called “X” to close the app. Where the “X” is may not be the location of the actual close button. I have deleted apps because I was downloading so many unwanted apps on my Kindle Fire. I gave up with the provider of my game apps and uninstalled all of their apps on all my devices.

  2. this does not solve the issue, this is a random article written based on a singular issue the journalist covered. The real problem are companies like motorola, who just put whatever they want when they want on your device. Android system update…hey lets put a bunch of apps on your phone we think you have to have.

  3. Along with denying permissions, denying access to the phone helps. Keep data off and when you turn in for the day, shut the phone down. With no power, no apps download. Extends battery life 30%, too.

    Most of the issues date back years, this isn’t new – altho new to me now in 2024. What seemed to start it I cant tell – new tablet linked by google might have kicked off something yet it’s the old device picking up all the trash. Up until now, nothing for years. Work thru the permissions, they are hidden well in confusing menus, and keep in mind another solution – you can get a new phone from somebody besides Samsung, who seems to currently be out of control. If all you need is a phone, not a small computer, there are plenty of options.

  4. I did every one of these things multiple times, and I’m still sitting here watching unwanted apps appear on my phone faster than I can delete them.
    The culprit is usually the most recent game I downloaded, and none of this can do anything to stop it.
    Just admit you have no clue!

  5. My biggest issue here is Samsung just randomly, out of the blue, dropping several games onto my phone that I never requested, searched for or desired in the first place. They seem to be treating me as if I’m a mental invalid, or something, that can’t think for myself and choose what to install and what to not install. Almost like they’re saying “Hey, we know you don’t REALLY want these, but we think we know better than you and that you aren’t really capable of making your own decisions, so WE’LL DO THAT FOR YOU! DON’T WORRY, YOU’LL BE JUST FINE!”. And mind you, it’s ALWAYS games, never any other kinds of apps. I have tried everything I’ve read to stop this, but still they come. Almost like my phone has been taken over. Very aggravating.
