Pop-up windows on Android can be both useful (discount notifications, important alerts from banks) and annoying (advertising, spam). But what to do if the desired pop-up is suddenly blocked by the system or browser? Most often, users encounter this problem when trying to receive an SMS verification code, open the web version of the messenger, or use an online service that requires notification permission.

Setting up pop-up windows depends on content type (browser pop-ups, system notifications, application permissions) and Android version (starting s Android 10 Google has tightened its security policy). In this article, we will look at all the current methods of unblocking - from changes in settings Chrome to manually adding exceptions for specific sites and applications.

⚠️ Important: Some pop-up windows can be dangerous - scammers often disguise them as them phishing pages. Always check the URL before entering personal information!

1. Allowing pop-ups in the Chrome browser by default blocks the majority of pop-ups, but you can manually add exceptions for trusted resources. This method works on all versions of Android, including the latest updates

Google Chrome By default, majority pop-ups are blocked, but you can manually add exceptions for trusted resources. This method works on all versions of Android, including the latest updates Chrome 124+.

Open your browser and go to ⋮ (Menu) → Settings → Site Settings → Pop-ups and redirects. Here you will see a slider "Pop-ups and redirects" —move it to position "Allowed". However, this will disable blocking for all sites, which is not secure. It is better to add an exception only for the required resource:

  • 🌐 Enter the address of the site where you want to unlock pop-ups (for example, web.whatsapp.com).
  • 🔍 Click on the icon lock in the address bar → Permissions → Pop-up windows.
  • 🔄 Select "Allow" and refresh the page (F5 or the ↻ icon).

If the window still does not open, clear the browser cache: Settings → Privacy → Clear data → Cached images and filesThis will help clear possible conflicts with saved settings.

Is the site added to exceptions?

Has the page been updated after the changes?

Is the browser cache cleared?

Has the "Traffic Saving" mode been checked (it can block scripts)?

2. Setting up pop-up windows in other browsers

Alternative browsers (Firefox, Samsung Internet, Opera) have their own blocking algorithms. Let's look at the key differences:

Browser Path to settings Features
Mozilla Firefox ⋮ → Settings → Permissions → Pop-up windows Supports "White list" of sites. Blocking is stricter than in Chrome.
Samsung Internet ⋮ → Settings → Sites and downloads → Pop-up windows Has a separate switch for notifications and pop-ups.
Opera ⚙ → Settings → Content → Pop-ups Enables the ad blocker by default - it must be disabled separately.

In Firefox i Opera a function is also available "Exceptions", similar to Chrome. But Samsung Internet may require additional permission for JavaScript - check this parameter in the settings site.

3. Allowing notifications for applications

If pop-up windows are not shown in mobile applications (for example, in VK, Telegram or banking services), the problem lies in the settings permissions.Android divides notifications into two types:

  • 📱 System notifications (appears in curtain).
  • 🖼️ Pop-up windows (open on top of the interface).

To allow both types:

  1. Go to Settings → Applications → [Application name] → Notifications.
  2. Activate the switch "Allow notifications".
  3. Find the item below "Pop-up windows" (or Display over other apps in English firmware) and enable it.

On some firmware (for example, MIUI from Xiaomi or ColorOS from Oppo) the path may be different: look for the "Special permissions" section or "Advanced."

💡

If the application is not displayed in the "Settings → Applications" list, try opening it at least once first - this will add it to the control menu.

4. Problems with pop-ups in web versions of messengers

Users often encounter pop-ups being blocked when using Web WhatsApp, Telegram Web or VK Messenger in a browser. Two problems are combined here: browser settings and limitations of the service itself.

For WhatsApp Web:

  • 🔗 Make sure you are opening the official website: https://web.whatsapp.com (fraudsters copy the design on phishing domains!).
  • 📱 On the phone in the application WhatsApp click ⋮ → Linked Devices → Link a Device and scan the QR code.
  • 🔄 If the window with the QR code does not appear, check whether it is blocked power saving mode or VPN.

For Telegram Web Additionally, you may need:

  • 🔐 Allow Cookie in the browser settings.
  • 🚫 Disable blocking extensions (for example, AdGuard or uBlock Origin).
Why does scanning a QR code not work?

If the phone camera does not recognize the QR code on the PC screen, try:

1. Increase the brightness of the computer screen.

2. Disable "Night mode" (it distorts colors).

3. Use another device for scanning (tablet or second phone).

5. Pop-up windows and energy saving modes

Few people know, but battery optimization modes (for example, Adaptive battery v Android 12+ or Ultra Power Saving on Samsung) can block background activity of applications, including the display of pop-ups. This applies to:

  • 🔋 Notifications from banking applications (SberBank Online, Tinkoff).
  • 📊 Pop-ups with analytics in games (for example, Clash of Clans).
  • 🔔 Notifications about new messages in instant messengers.

To fix this:

  1. Open Settings → Battery → Battery mode.
  2. Select "Performance" or "Adaptive" (but not "Battery Saving").
  3. For critical applications (banking, instant messengers), add them to exceptions: Settings → Battery → Battery optimization → All apps → [Select app] → Do not optimize.

On devices Xiaomi check additionally Settings → Battery → Mode selection → No restrictions for desired application.

💡

Power saving modes save power, but often break the background operation of applications. Always add banking and work applications to exceptions!

6. VPN

Security applications (Kaspersky, Avast, Dr.Web) and VPN services (NordVPN, ProtonVPN) can intercept traffic and block “suspicious” pop-ups - even if they are legitimate. For example, Kaspersky Internet Security blocks by default:

  • 🛡️ Pop-ups with password entry forms.
  • 🔗 Redirections to external sites.
  • 📢 Advertising banners (including notifications from loyalty apps).

To allow pop-ups:

  1. Open your antivirus and find the section "Web protection" or "Activity control".
  2. Add the problematic site to white list (for example, to Kaspersky this Settings → Advanced → Threats and exclusions).
  3. For VPN, check the settings "Ad blocking" - disable it temporarily.

⚠️ Attention: disabling antivirus protection increases the risk of virus infection. Use this method only for trusted resources (banks, government services) and turn the protection back on after finishing work.

7. Manual resolution via ADB (for advanced)

If standard methods do not work, and pop-up windows are critical (for example, for testing) web applications), you can use ADB commands. This method is suitable for Android 8.0+ and requires connecting the phone to the PC.

Steps:

  1. Enable USB Debugging on the phone: Settings → About phone → Build number (press 7 times) → return to Settings → System → For developers → USB debugging.
  2. Connect your phone to the PC and open Command Line (Windows) or Terminal (Mac/Linux).
  3. Enter the command to check the connection: 
    adb devices

    (the device serial number should appear).

  4. Allow pop-ups for a specific package (for example, Chrome): 
    adb shell appops set com.android.chrome SYSTEM_ALERT_WINDOW allow

For other applications, replace com.android.chrome with their package name (you can find it through App Inspector or website APKMirror).

⚠️ Attention: Incorrect use of ADB can disrupt the system. Do not change permissions for system applications (for example, com.android.systemui) without understanding the consequences.

8. Frequent errors and their solutions

Even after all the settings. pop-ups may not work. Let's consider typical scenarios and fixes:

Problem Possible reason Solution
Pop-ups are blocked only on Wi-Fi The provider uses DNS filtering Change DNS to 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare)
Windows open, but are empty Blocking scripts with the browser Disable "Pop-up blocker" and "Tracking protection"
Notifications arrive with a delay Battery optimization or Doze Mode Add the application to exceptions (see section 5)
Pop-ups only work after a reboot Application cache conflict Clear the cache and application data in the settings

If the problem persists, check:

  • 🔄 Is your phone firmware updated? (Settings → System → Software update).
  • 📱 Are there any restrictions from the operator (for example, blocking ports for corporate devices).
  • 🛠️ Are custom firmware installed (for example, LineageOS), which may have their own security rules.
💡

For diagnostics, use Safe Mode (press the power button → "Safe Mode") If pop-ups work in it, the problem is in one of the installed applications.

FAQ: Answers to frequently asked questions

❓ Why are pop-ups blocked even after allowing them in the settings?

This may happen due to:

  • Conflict with other applications (for example, Greenify or Battery Doctor pause the background activity).
  • Corporate policy restrictions (on work phones with an MDM profile).
  • Blockings at the router level (check your DNS/firewall settings).

Solution: disable third-party applications for optimization one by one and check the result.

❓ How to allow pop-ups in the application if there is no "Pop-up windows" item in the settings?

On some firmware (for example, EMUI from Huawei) this item is hidden. Try:

  1. Go to Settings → Applications → [Application] → Permissions → Advanced.
  2. Find item "Display on top of other windows" (or Display over other apps).
  3. If it is not there, use the ADB command (see section 7).
❓ Is it possible to allow pop-ups for only one site in Chrome?

Yes, this is done through the settings of a specific site:

  1. Open the site in Chrome.
  2. Tap the icon lock in the address line.
  3. Select Permissions → Pop-ups → Allow.

This will not disable blocking for other resources.

❓ Why after Android updates have notifications stopped working?

New versions of Android (starting from Android 13) tighten the rules for background processes. To get notifications back:

  • Check the section Settings → Applications → [Application] → Notifications → Channels —turn on all channels.
  • Disable "Adaptive notifications" in Settings → Notifications → Additional.
  • Update the problematic application to the latest version.
❓ Is it safe to allow pop-ups?

It depends on the context:

  • ✅ Safe for trusted sites (banks, government services, messengers).
  • ⚠️ Risky for unknown resources - pop-ups may contain phishing links or malicious code.
  • 🚫 Prohibited on sites with pirated content (they often distribute viruses through pop-ups).

Recommendation: use a separate browser (for example, Firefox Focus) for sites that require pop-ups, and clear its data after use.
