The update to Android 11 brought not only a new visual style and improved notifications, but also introduced a number of strict restrictions aimed at increasing data security and privacy. For the average user, these changes often go unnoticed, but enthusiasts and advanced users encounter noticeable inconveniences. We are talking about the impossibility of direct access to the file system via USB, blocking the installation of applications from unknown sources without unnecessary confirmation, and aggressive operation of the power management system.
Many people wonder whether it is possible to return the usual freedom of action without losing the stability of the device. The answer is yes, but requires caution. Removing restrictions in the new version of the OS involves the use of hidden developer settings, special utilities like ADB or even receiving root access. It is important to understand that each action changes the balance between the convenience and security of your gadget.
In this guide, we will analyze in detail the main barriers implemented in Android 11and provide step-by-step guide on how to bypass them. You will learn how to regain full access to a folder Android/obb, how to disable intrusive system warnings and how to get old applications to work correctly in the new environment.
Restricting access to the file system via USB
One of the most painful changes for users was the change in the protocol for working with files when connecting a smartphone to a computer. In previous versions of Android, you could freely navigate through all the internal memory directories. Now the system hides the root folder Android and its subdirectories data and obb when connecting via protocol MTP.
This is done to prevent attackers or malware from gaining access to confidential application data. However, this creates problems when transferring game caches, mods, or backups. Standard Windows or macOS Explorer simply does not display these folders, showing them empty or completely hidden.
There are several ways to bypass this limitation without voiding your warranty. The simplest is to use specialized explorer applications that work using the SAF (Storage Access Framework) protocol. They request special permission from the system and gain access to hidden areas.
- 📂 Use the application Files by Google or Solid Explorer to manage files inside the phone.
- 💻 Connect the phone in
PTP(camera) mode insteadMTP, although this will limit access only to media files. - 🔌 Use the utility ADB to directly copy files through the computer command line.
⚠️ Attention! Directly editing files in a folder
Android/datamay cause applications to crash. Always create a backup copy before making changes.
If you critically need to see these folders on your computer, the only reliable solution is to use the command ADB. This requires enabling USB debugging, but gives full control over the file system, ignoring MTP restrictions.
Setting up access via ADB and command line
For those who are not afraid of the command line, the tool Android Debug Bridge remains the “golden key” to the system. It allows you to control the device at a deep level, bypassing many interface restrictions Android 11. First of all, you need to activate developer mode.
Go to Settings → About phone and quickly click 7 times on the item Build number. After this, a new section “For Developers” will appear in the settings menu. Inside, find the item USB debugging and activate it. Connect your smartphone to the PC with a cable.
On the computer, enter the command to check the connection:
adb devicesA permission request will appear on the phone screen debugging from this computer. Confirm it. Now you can use the command adb shell to enter the device shell. To copy files, use the commands adb push (download to phone) and adb pull (download from phone).
☑️ Preparing to work with ADB
This method works stably and does not require superuser rights. It is ideal for one-time operations to transfer large amounts of data to protected directories that are hidden from the average user.
Disabling tracking and advertising ID protection
Android 11 increased control over advertising identifiers. The system now allows users to completely reset or delete their advertising ID, making targeted advertising less effective. However, some applications may not work correctly or constantly require this feature to be enabled.
To manage these settings, go to the Settings → Google → Advertisingsection. Here you will see the Remove Advertising ID option. If you want to remove restrictions on data collection for specific applications (for example, for testing), you may need to reset the ID.
This version also tightens control over access to the clipboard and camera. Indicators in the corner of the screen let you know when an app is using your microphone or camera. It is impossible to remove these indicators using standard means, as this is a security requirement Google, but you can restrict access to specific apps.
- 🔒 Go to
Settings → Privacy → Permission Manager. - 📹 Disable access to the camera for applications that do not need it in the background.
- 📋 Limit access to the clipboard in the settings of individual applications.
⚠️ Attention! Removing the advertising ID completely may cause some free apps to stop functioning or show errors when launched.
Remember that complete anonymity in the mobile ecosystem is a trade-off. By opting out of tracking, you may lose content personalization in some services.
If an app constantly requests access to the clipboard for no apparent reason, try using the "Show notification when clipboard is accessed" feature to monitor its actions.
Solving problems installing apps from unknown sources
Q Android 11 The process of installing APK files has become more confusing. The system now requires granting permission not just for the browser or explorer, but for a specific source at the time of installation. Often, users encounter the “Application not installed” error or an endless loop of permission requests.
The main problem lies in the new permissions mechanism Package Installer. When you try to install a file, the system blocks the action until you explicitly allow a specific application (for example Chrome or Telegram) to install unknown applications. This is done at the time of the installation attempt, and not in the general settings.
If the standard installer gives an error, try using an alternative package manager, for example SAI (Split APKs Installer). This application can correctly handle modern installation file formats and bypass some signature validation checks.
| Problem | Possible cause | Solution |
|---|---|---|
| Error "Application not installed" | Signature conflict or Android version is lower than required | Uninstall the old version of the application before installing the new one |
| The permission request does not disappear | Package Installer service has failed | Clear the cache of the "Installer" application packages" in settings |
| Block Play Protect | The application is not certified by Google | Temporarily disable scanning in the Play Store settings |
| APK file is damaged | Incomplete download file | Reload the file from another source |
It is also worth checking whether the function Google Play Protect is enabled in aggressive mode. Go to the Play Market store settings, select the Play Protect section and disable scanning applications before installation.
What to do if the system writes “Installation is blocked by the administrator”?
This message often appears if a corporate profile or antivirus with administrator rights is installed on the device. Go to Settings → Security → Device administrators and temporarily disable suspicious profiles.
Managing background activity restrictions
Battery optimization Android 11 has become so aggressive that many instant messengers and useful utilities stop receiving notifications or are unloaded from memory immediately after collapsing. This is not a bug, but a feature of the system Doze and adaptive power mode.
To remove this limitation for important applications, you must manually change the battery settings. Go to Settings → Applications → [Select an app] → Battery. By default, the mode is “Optimized”. You need to switch it to “Unlimited”.
This action will allow the application to run in the background indefinitely, using the network connection and CPU time even when the screen is off. Be careful: applications in this mode can significantly reduce the battery life of your smartphone per day.
Also check your autorun settings. On smartphones of brands Xiaomi, Huawei i Samsung there are additional task managers that can kill processes regardless of Android settings. Find the application in the autorun list and allow it to start along with the system.
⚠️ Attention! Unlimited mode disables power saving for a specific application. Use it only for instant messengers, email clients or trackers, and not for games or video players.
Obtaining root access and removing system locks
For users who do not have enough standard settings, there remains a radical method - obtaining superuser rights (Root). This allows you to completely remove any restrictions Android 11, including deleting system applications and modifying the kernel.
The process usually begins with unlocking the bootloader (Bootloader). On devices Google Pixel this is done with one command fastboot flashing unlock. On smartphones Xiaomi a wait of 7 to 30 days is required after linking the account. It is worth noting that unlocking the bootloader completely erases all data from the devicetherefore, a backup copy is required.
After unlocking the bootloader, a custom recovery is installed (for example, TWRP), through which it is flashed utility Magisk. It is this that provides access to root and allows you to hide these rights from banking applications and games with anti-cheat.
- 🔓 Unlocking the bootloader will void the manufacturer's warranty.
- 🛡️ Some applications (banks, Netflix) may stop working without additional Magisk Hide settings.
- ⚡ You you get full control over the processor frequency and other core parameters.
This is the path for experienced users. An error at any stage can turn a smartphone into a brick. If you are not confident in your abilities, it is better to limit yourself to the developer settings and ADB.
Obtaining root access gives maximum freedom, but carries security risks and loss of warranty. For most tasks to remove restrictions, ADB rights are sufficient.
Frequently asked questions (FAQ)
Is it possible to regain access to the Android folder in Windows Explorer without Root?
Yes, this can be done using the ADB command. Connect your phone, enter adb shell, and then use the command am start -a android.intent.action.VIEW -d content://com.android.externalstorage.documents/root/primary or simply copy the files with commands adb pull/push. Standard Windows Explorer will not show these folders due to limitations of the MTP protocol in Android 11.
Why do applications crash immediately after installation on Android 11?
A common reason is storage access restrictions. Android 11 introduces Scoped Storage, which prevents apps from accessing all memory. If the application is old and not adapted to the new rules, it may crash. Try to find an updated version of the application or grant it all possible permissions manually in the settings.
Is it safe to disable Google Play Protect?
Disabling Play Protect reduces the level of protection against viruses and malware. This should only be done temporarily if you are sure of the source of the APK file being installed. It is not recommended to keep protection turned off at all times, as the system will stop scanning new applications for threats.
How to disable notifications that an application is using the camera or microphone?
It is impossible to completely disable these indicators (the green dot in the corner) using standard means, since this is a Google security requirement for Android 11 and higher. You can only deny the app access to the camera or microphone in the privacy settings, then the indicator will stop lit, but the app will not be able to use the functions.
Will unlocking the bootloader reset the Knox counter on Samsung?
Yes, on Samsung devices, unlocking the bootloader will irreversibly fire the Knox trigger (0x1). This means that you will permanently lose access to protected features such as Samsung Pay, Secure Folder and some banking applications, even if you lock the bootloader again.
