The administrator can configure the settings of Anti-Malware and Web Protection in the EMM system console. In this case, notifications about app operation are available only in the interface of the Kaspersky Endpoint Security for Android app (Reports).

Known issues when upgrading the app version

You can upgrade Kaspersky Endpoint Security for Android only to a more recent version of the app. Kaspersky Endpoint Security for Android cannot be downgraded to an older version.
To upgrade Kaspersky Endpoint Security for Android using a standalone installation package, installation of apps from unknown sources must be allowed on the user's mobile device.
You can update through Google Play if Kaspersky Endpoint Security for Android was installed from Google Play. If the app was installed using another method, you cannot update through Google Play.
You can update through Kaspersky Security Center if Kaspersky Endpoint Security for Android was installed through Kaspersky Security Center. If the app was installed from Google Play, you cannot update the app through Kaspersky Security Center.
After you upgrade administration plug-ins to Technical Release 33, the Kaspersky Endpoint Security for Android app must also be upgraded to Technical Release 33. Otherwise, you will not be able to activate Samsung KNOX on some of your users' devices.

Known issues in Anti-Malware operation

Due to technical limitations, Kaspersky Endpoint Security for Android cannot scan files with a size of 2 GB or more. During a scan, the app skips such files without notifying you that such files were skipped.
For additional analysis of a device for new threats whose information has not yet been added to anti-malware databases, you must enable the use of Kaspersky Security Network. Kaspersky Security Network (KSN) is an infrastructure of cloud services providing access to Kaspersky online knowledge base with information about the reputation of files, web resources, and software. To use KSN, the mobile device must be connected to the internet.
In some cases, updating anti-malware databases from the Administration Server on a mobile device may fail. In this case, run the anti-malware database update task on the Administration Server.
On some devices, Kaspersky Endpoint Security for Android does not detect devices connected over USB OTG. It is not possible to run a malware scan on such devices.
On devices running Android 11 or later, the Kaspersky Endpoint Security for Android app can't scan the "Android/data" and "Android/obb" folders and detect malware in them due to technical limitations.
On devices running Android 11 or later, the user must grant the "Allow access to manage all files" permission.
On devices running Android 7.0 or later, the configuration window for the malware scan run schedule might be incorrectly displayed (management elements are not shown). This issue is caused by a well-known defect in Android 7.
On devices running Android 7.0, real-time protection in the extended mode does not detect threats in files that are stored on an external SD card.
On devices running Android 6, Kaspersky Endpoint Security for Android does not detect the downloading of a malicious file to the device memory. A malicious file may be detected by Anti-Malware when the file is run, or during a malware scan of the device. This issue is caused by a well-known defect in Android 6. To ensure device security, it is recommended to configure scheduled malware scans.

Known issues in Web Protection operation

Web Protection on Android devices is supported only by Google Chrome, HUAWEI Browser, Samsung Internet Browser, and Yandex Browser.
The Custom Tabs feature is supported by Google Chrome, HUAWEI Browser, and Samsung Internet Browser.
Web Protection for HUAWEI Browser, Samsung Internet Browser, and Yandex Browser does not block sites on a mobile device if the work profile is used and Web Protection is enabled only for the work profile.
Kaspersky Endpoint Security in the work profile scans only the website domain in HTTPS traffic. Malicious and phishing websites may remain unblocked if the app installed in the work profile. If the domain is trusted, Web Protection can skip a threat (for example, https://trusted.domain.com/phishing/). If the domain is untrusted, Web Protection blocks malicious and phishing websites.
For Web Protection to work, you must enable the use of Kaspersky Security Network. Web Protection blocks websites based on the KSN data on the reputation and category of websites.
Forbidden websites may remain unblocked by Web Protection on devices running Android 6 with Google Chrome version 51 (or any earlier version) installed if the website is opened in the following ways (this issue is caused by a well-known defect in Google Chrome):
- From search results.
- From the bookmarks list.
- From search history.
- Using the web address autocomplete function.
- Opening the website in a new tab in Google Chrome.
Forbidden websites may remain unblocked in Google Chrome version 50 (or any earlier version) if the website is opened from Google search results while the Merge Tabs and Apps feature is enabled in the browser settings. This issue is caused by a well-known defect in Google Chrome.
Websites from blocked categories may remain unblocked in Google Chrome if the user opens them from third-party apps, for example, from an IM client app. This issue is related to how the Accessibility service works with the Chrome Custom Tabs feature.
Forbidden websites may remain unblocked in Samsung Internet Browser if the user opens them in background mode from the context menu or from third-party apps, for example, from an IM client app.
Kaspersky Endpoint Security for Android must be set as an Accessibility feature to ensure proper functioning of Web Protection.
On some Xiaomi devices, the "Display pop-up window" and "Display pop-up windows while running in the background" permissions should be granted for Web Protection to work.
When entering a website address in Web Protection settings, adhere to the following rules:
- For Android devices, specify the address in regular expressions format (for example, https://example.com.*).
- For iOS MDM devices, specify the HTTP or HTTPS data transport protocol (for example, http://www.example.com).
Allowed websites may be blocked in Samsung Internet Browser in the Only listed websites are allowed Web Protection mode when the page is refreshed. Websites are blocked if a regular expression contains advanced settings (for example, ^https?://example.com/pictures/). It is recommended to use regular expressions without additional settings (for example, ^https?://example.com).
If Web Protection is set to All websites are blocked, Kaspersky Endpoint Security for Android does not block search in the Google Search widget. Instead, it blocks user access to the search results.
In a work profile, if Web Protection is set to All websites are blocked, Kaspersky Endpoint Security for Android endlessly reloads the Google Chrome home page, blocks the browser, and interferes with the device.
To make sure that the Kaspersky Endpoint Security for Android app allows or blocks access to the specified website in all supported versions of Google Chrome, HUAWEI Browser, Samsung Internet Browser, or Yandex Browser, include the same URL twice, once with the HTTP protocol (e.g., http://example.com) and once with the HTTPS protocol (e.g., https://example.com). As an alternative, you can use regular expressions.
In Yandex Browser and Samsung Internet Browser, malicious and phishing websites may remain unblocked. This is because only the website domain is scanned, and if it is trusted, Web Protection can skip a threat.
If Kaspersky Endpoint Security for Android is not set as an Accessibility feature, Web Protection may block an allowed website that loads some elements from a website with a domain that is not in the list of allowed domains.

Known issues in Anti-Theft operation

For timely delivery of commands to Android devices, the app uses the Firebase Cloud Messaging (FCM) service. If FCM is not configured, commands will be delivered to the device only during synchronization with Kaspersky Security Center according to the schedule defined in the policy, for example, every 24 hours.
To lock a device, Kaspersky Endpoint Security for Android must be set as the device administrator.
To lock devices running Android 7.0 or later, Kaspersky Endpoint Security for Android must be set as an Accessibility feature.
On some devices, Anti-Theft commands may fail to execute if Battery Saver mode is enabled on the device. This defect has been confirmed on Alcatel 5080X.
To locate devices running Android 10 or later, the user must grant the "All the time" permission to device location.
To take a mugshot with devices running Android 11 or later, the user must grant the "While using the app" permission to access the camera.

Known issues in App Control operation

Kaspersky Endpoint Security for Android must be set as an Accessibility feature to ensure proper functioning of App Control. This does not apply to device owner mode.
For App Control (app categories) to work, you must enable the use of Kaspersky Security Network. App Control determines the category of an app based on data that is available in KSN. To use KSN, the mobile device must be connected to the internet. For App Control, you can add individual apps to the lists of blocked and allowed apps. In this case, KSN is not required.
When configuring App Control, it is recommended to clear the Block system apps check box. Blocking system apps may lead to problems in device operation.
On iOS MDM devices, if you specify allowed apps in the list of apps allowed to be installed, all apps except system apps and those added to the list of allowed apps will be hidden on the device screen.
On some HUAWEI and Honor personal devices, apps from allowed categories may be blocked and apps from forbidden categories may remain unblocked. This is because the category for some apps from App Gallery cannot be correctly defined.
On some Samsung and Oppo devices, app icons may remain hidden on the home screen after clearing the Block system apps check box. This is due to limitations of the Android operating system.

Known issues when configuring certificates in iOS MDM policy

When you add a certificate to an iOS MDM policy and attempt to save or close the policy, MMC-based Administration Console of Kaspersky Security Center may crash, but the certificate is saved to the policy settings.

Known issues when configuring email

Remote configuration of a mailbox is available only on the following devices:
- iOS MDM devices.
- Samsung devices (Exchange ActiveSync).
- Android devices with the TouchDown mail client installed.
  In previous versions of Kaspersky Endpoint Security for Android, you can use Kaspersky Security Center to remotely configure TouchDown profile settings on a user's device. TouchDown support has been discontinued in Kaspersky Endpoint Security for Android Service Pack 4. For more detail, refer to the Symantec technical support website.
  
  After upgrading the Kaspersky Endpoint Security for Android Administration Plug-in, the TouchDown settings in the policy are hidden but saved. When new devices are connected, TouchDown settings will be configured after the policy is applied.
  
  After the policy is modified and saved, TouchDown settings will be deleted. The TouchDown settings on a user's devices will be cleared after a policy is applied.

Known issues when configuring device unlock password strength

On devices running Android 10 or later, Kaspersky Endpoint Security resolves the password strength requirements into one of the system values: medium or high.
If the password length required is 1 to 4 symbols, then the app prompts the user to set a medium-strength password. It must be either numeric (PIN), with no repeating or ordered (e.g. 1234) sequences; or alphanumeric. The PIN or password must be at least 4 characters long.

If the password length required is 5 or more symbols, then the app prompts the user to set a high-strength password. It must be either numeric (PIN), with no repeating or ordered sequences; or alphanumeric (password). The PIN must be at least 8 digits long; the password must be at least 6 characters long.
On devices running Android 10 or later, using a fingerprint to unlock the screen can be managed for work profile only.
On devices running Android 7.1.1, if the unlock password does not meet the corporate security requirements (Compliance Control), the Settings system app may function improperly when an attempt is made to change the unlock password through Kaspersky Endpoint Security for Android. The issue is caused by a well-known defect in Android 7.1.1. In this case, to change the unlock password, use the Settings system app only.
On some devices running Android 6 or later, an error may occur when screen unlock password is entered, if device data is encrypted. This issue is related to specific features of the Accessibility service with MIUI firmware.
On some HUAWEI devices, an issue message about too simple screen unlocking method appears, and the user must set a PIN code that is compliant with policy requirements. For more details about setting a correct PIN code on HUAWEI devices, please refer to Configuring a strong unlock password for an Android device.

Known issues when configuring Wi-Fi

On devices running Android version 8.0 or later, settings of the proxy server for Wi-Fi cannot be redefined with the policy. However, you can manually configure the proxy server settings for a Wi-Fi network on the mobile device.
On supervised iOS MDM devices, if you select the Force connection to allowed Wi-Fi networks only (supervised only, iOS 14.5+) check box when configuring feature restrictions, the current Wi-Fi connection will be interrupted even if it belongs to the allowed Wi-Fi networks list. This is due to iOS operating system specifics. The user must reconnect to the Wi-Fi network manually.

Known issues when configuring APN

Remote configuration of APN is available only on iOS MDM devices or Samsung devices.
Configure APN for iOS MDM devices in the Cellular communications section. The APN section is out of date. Before configuring the APN settings, make sure that the Apply on device check box in the APN section is cleared.

Known issues with Firewall

Use of Firewall is available only on Samsung devices.

Known issues when configuring VPN

Remote configuration of VPN is available only on the following devices:
- iOS MDM devices.
- Samsung devices.
When you set up a VPN connection for selected domains in Safari, if you change the Connect automatically option, the changes are not applied on the device. The Connect automatically check box is selected by default and we recommend against changing it if you want to activate a VPN automatically for specified domains.

Known issues with App removal protection

Kaspersky Endpoint Security for Android must be set as the device administrator.
To protect the app from removal on devices running Android 7.0 or later, Kaspersky Endpoint Security for Android must be set as an Accessibility feature.

Known issues when configuring device restrictions

On devices running Android 10 or later, prohibiting the use of Wi-Fi networks is not supported.
On devices running Android 11 or later, Kaspersky Endpoint Security for Android must be set as an Accessibility feature. Kaspersky Endpoint Security for Android prompts the user to set the app as an Accessibility feature through the Initial Configuration Wizard. The user can skip this step or disable this service in the device settings at a later time. If this is the case, you will not be able to restrict use of the camera.

Known issues when sending commands to mobile devices

On devices running Android 12 or later, if the user granted the "Use approximate location" permission, the Kaspersky Endpoint Security for Android app first tries to get the precise device location. If this is not successful, the approximate device location is returned only if it was received not more than 30 minutes earlier. Otherwise, the Locate device command fails.
The Locate device command does not work on Android devices if Google Location Accuracy is disabled in settings. Please be aware that not all Android devices come with this location setting.
If you send the Enable Lost Mode command to a supervised iOS MDM device without a SIM card and this device is restarted, the device won't be able to connect to Wi-Fi and receive the Disable Lost Mode command. This is a specific feature of iOS devices. To avoid this issue, you can either send the command only to devices with a SIM card, or insert a SIM card into the locked device to allow it to receive the Disable Lost Mode command over the mobile network.

Known issues with Android work profile

If you create an Android work profile by using a policy, the user must grant the "Allow access to manage all files" permission to Kaspersky Endpoint Security for Android that is installed on the devices running Android 11 or later and that is related to the work profile.
The Prohibit activation of USB debugging mode Android work profile function does not work on devices with Android 13. This is caused by an issue in Android 13.
On some Xiaomi devices with Android work profile, the work profile may be unlocked by a fingerprint only if you set the Period of inactivity before the device screen locks value after setting a fingerprint as the screen unlocking method.
When the Deny permissions automatically action is selected in the Granting runtime permissions for apps setting, if the user configures the necessary permissions for an app after device synchronization with Kaspersky Security Center but before this app requests all permissions, these permissions cannot be changed without reinstalling the app or wiping its data.

Known issues with specific devices

On certain devices (for example, HUAWEI, Meizu, and Xiaomi), you must grant Kaspersky Endpoint Security for Android an autostart permission or manually add it to the list of apps that are started when the operating system starts. If the app is not added to the list, Kaspersky Endpoint Security for Android stops performing all of its functions after the mobile device is restarted. In addition, if the device has been locked, you cannot use a command to unlock the device. You can unlock the device only by using a one-time unlock code.
On certain devices (for example, Meizu and Asus) running Android 6 or later, after encrypting data and restarting the Android device, you must enter a numeric password to unlock the device. If the user uses a graphic password to unlock the device, you must convert the graphic password to a numeric password. For more details about converting a graphic password into a numeric password, please refer to the Technical Support website of the mobile device manufacturer. This issue is related to the operation of the Accessibility Features service.
On some HUAWEI devices running Android 5.Х, after Kaspersky Endpoint Security for Android is set as an Accessibility feature, an incorrect message about the lack of appropriate rights may be displayed. To hide this message, enable the app as a protected app in the device settings.

On some Xiaomi devices, the user can use the Foreground Services Task Manager to stop Kaspersky Endpoint Security for Android from running in the background. This issue is due to some features of Xiaomi software.
On some Xiaomi devices, when setting the password length to more than 5 characters in a policy, the user will be prompted to change the screen unlock password instead of the PIN code. You cannot set a PIN code that has more than 5 characters. This issue is due to some features of Xiaomi software.
On Xiaomi devices with MIUI firmware running Android 6, the Kaspersky Endpoint Security for Android icon may be hidden in the status bar. This issue is due to some features of Xiaomi software. It is recommended to allow the display of notification icons in Notifications settings.
On some Nexus devices running Android 6.0.1, the privileges required for proper operation cannot be granted through the Quick Start Wizard of Kaspersky Endpoint Security for Android. This issue is caused by a well-known defect in Security Patch for Android by Google. To ensure proper operation, the required privileges must be manually granted in the device settings.
On certain Samsung devices running Android 7.0 or later, when the user attempts to configure unsupported methods for unlocking the device (for example, a graphical password), the device may be locked if the following conditions are met: Kaspersky Endpoint Security for Android removal protection is enabled and screen unlock password strength requirements are set. To unlock the device, you must send a special command to the device.
On certain Samsung devices, it is impossible to block the use of fingerprints for unlocking the screen.
Web Protection cannot be enabled on some Samsung devices, if the device is connected to a 3G/4G network, has Battery Saver mode enabled and restricts background data. It is recommended to disable the function that restricts background processes in Battery Saver settings.
On certain Samsung devices, if the unlock password does not comply with corporate security requirements, Kaspersky Endpoint Security for Android does not block the use of fingerprints for unlocking the screen.
After executing Anti-Theft commands (such as Locate, Device Lock, Unlock, and Mugshot), the mobile certificate and the VPN certificate may be deleted on some Samsung devices. The certificates have to be reinstalled to continue. This issue occurs due to the Mobile Device Fundamentals Protection Profile (MDFPP) security standard.
On some Honor and HUAWEI devices, you cannot restrict the use of Bluetooth. When Kaspersky Endpoint Security for Android attempts to restrict the use of Bluetooth, the operating system shows a notification containing the options to reject or allow this restriction. The user can reject this restriction and continue to use Bluetooth.
On some Samsung devices, after Kaspersky Endpoint Security is installed or updated from a standalone installation package, KNOX MDM profile activation is unavailable.
On Blackview devices, the user can clear the memory for the Kaspersky Endpoint Security for Android app. As a result, the device protection and management are disabled, all defined settings become ineffective, and the Kaspersky Endpoint Security for Android app is removed from the Accessibility features. This is because this vendor's devices provide the customized Recent screens app with elevated privileges. This app can override Kaspersky Endpoint Security for Android settings and cannot be replaced because it is part of the Android operating system.
On some Google Pixel devices running Android 11 or earlier, the Kaspersky Endpoint Security for Android app crashes immediately after the start. This is caused by an issue in Android.
