How to remove the blocking of applications on Android Xiaomi

Owners of Xiaomi, Redmi and Poco smartphones often face a situation where the installed application ceases to work correctly or is completely blocked by the system. This can manifest itself in the inability to start the program, a sudden closure of the process or lack of notifications. Aggressive optimization of the MIUI shell or HyperOS is designed to save battery power, but sometimes damages the functionality of the device by blocking the services necessary for the user.

There are many reasons for this, from built-in security mechanisms to third-party software installed by the user or previous owner, and understanding the source of the problem is the first step to solving it. In most cases, unlocking applications does not require complex technical skills or obtaining superuser rights, it is enough to fine-tune system parameters.

In this article, we will look at all possible lock scenarios and provide step-by-step instructions for eliminating them, learn how to set up auto-start, disable power saving for specific programs, and bypass restrictions set through Google Play or specialized utilities.

Diagnostics of the type of lock on a smartphone

Before you start taking action, you need to determine exactly what causes the program to stop. Android based on MIUI has several layers of protection that can conflict with each other. Most often the problem lies in the battery settings, but you can not exclude the influence of third-party factors.

Note the behavior of the device. If the application simply does not start or crashes immediately after opening, it is likely to be due to file corruption or incompatibility. If the program works but does not send notifications or stops in the background, the culprit is energy saving. In some cases, the user may accidentally activate Child Mode or set restrictions through the digital balance.

For primary diagnosis, follow the following steps:

• 🔍 Check if the application is set to "Sleep" in the battery settings.
• 🚫 Make sure the program is not blocked in the "Security" section" -> "Licenses and restrictions".
• 📡 Check if you have access to the network for a specific application.

⚠️ Note: If the lock is accompanied by a pop-up demanding payment for unlocking files or devices, this is the action of the encryption virus. In this case, the standard settings will not help, you will need antivirus treatment or a complete reset.

Users often confuse system restrictions with blockages by app developers, such as some services that may not work in certain regions or on modified firmware, and make sure the problem is local and is related to your Xiaomi settings.

Set up auto-start and work in the background

The most common reason apps are blocked or not working properly on Xiaomi smartphones is because of the aggressive memory management policy, which automatically shuts down processes that it believes are consuming too much resources, and to avoid this, it is necessary to manually allow the program to run in the background.

First of all, you need to activate autorun. Without this permission, the operating system will kill the process every time you turn down an application or lock the screen. To do this, go to the Settings menu, find the Application section, and select Autorun. In the list that opens, find the desired program and activate the switch.

The current versions of HyperOS and MIUI have a separate menu to manage the power consumption of each application. Go to Settings -> Applications -> All applications, select the desired program and click on Battery Savings.

Once the settings are changed, it is recommended that you restart the device to take effect, ensuring that MIUI Optimization system services recalculate the priorities of the processes running.

It's worth noting that some global firmware versions may have slightly different paths to settings. If you don't find AutoStart in the basic settings, use the built-in Security app, which has a separate section on permissions and running programs.

Removing Restrictions Through the Security Menu

The built-in security suite on Xiaomi devices has broad powers and can block applications even if all permissions are available, including license settings, ad blocker and background activity restrictions that take precedence over Android system settings.

Open the Security app (green icon with shield). In the upper right corner, click on the gear icon to get into the settings. Find the Licenses or Permissions section. Make sure the problem application has access to the necessary functions: microphone, camera, geolocation and memory. Lack of at least one critical resolution can lead to locking functionality.

Also on the Security menu, there is often a "Ad Block" feature, which if it's activated globally, some apps may stop downloading content because they're considered blocked. Try temporarily disabling this feature for verification.

An important step is to clear the cache and the application itself through this menu, and sometimes accumulated errors in the configuration files lead the system to perceive the program as malicious or unstable.

⚠️ Note: When you clean the application data (“Erase Data”), all local information inside the program will be deleted. Make sure you have a backup or remember your login login login login login.

Managing Parental Controls and Digital Balance

If a device has time limits or content blocking, it is likely that Parental Controls or Google Family Link features are activated.This is a common situation where the phone is bought by hand or transferred to another family member, and the old settings remain active.

Check the settings in the Digital Well-being section, which shows usage statistics and time limits for each application. If the time is up, the app icon can turn grey and the launch can be blocked until the next day. To remove the restriction, you either need to increase the limit or completely disable the timer for a particular program.

If you use Family Link, you can only unlock the app from the parent's device, the child's phone will display a request for additional time or permission, and if you don't have access to the parent's account, the only way out is to completely reset the phone settings with deleting the Google account, which will require you to confirm the password from the owner's account.

Also worth checking is the built-in Security -> Parental Controls app. MIUI has its own restriction mechanism that can block the installation or launch of apps with a certain age rating or content.

• 👨‍👩‍👧‍👦 Check active profiles in Google settings.
• ⏱ Reset the timers of use in Digital Well-being".
• 🔐 Delete Unknown Device Administrator Profiles.

Sometimes the lock is linked to a Guest profile or a second space.Make sure you try to run the app in the main user profile where you have full administrator rights.

💡

If you can’t uninstall the Parental Controls app, try turning off the internet before you try to uninstall it, which will prevent you from sending a notification to your parents, although this doesn’t always work in modern versions of Android.

Operator blocking and regional restrictions

Not all locks come from phone settings. Sometimes a mobile provider or ISP restricts access to certain resources or applications. Xiaomi smartphones with global firmware can have conflicts when using services intended for the Chinese market, and vice versa.

Regional restrictions are common in TV viewing apps, streaming services, and banking programs, and if the app says "Not available in your region" or simply doesn't load the content, the problem isn't blocking the process, it's filtering traffic. IP-addresses or use of alternatives DNS.

To change DNS, go to Settings -> Connection and Sharing -> Private DNS. Select "DNS Provider Host Name" and type in an address like dns.google or 1.1.1.1. This can help bypass simple carrier locks.

An incorrect system date often leads to security certificate errors, causing applications (especially banking and social networks) to refuse to connect to the server, simulating a lock.

⚠️ Note: Using third-party services to circumvent regional restrictions may violate the application terms and conditions.

If you are using a corporate SIM-map, restrictions can be set at the level of the tariff plan.

💡

Regional content blocking is resolved by changing network settings or DNS, while system blocking requires changing access rights in MIUI.

Resetting network and application settings as a radical method

When none of the above methods have worked, and the application continues to be blocked or malfunctioning, more radical measures must be taken: resetting network settings and resetting the settings of the applications themselves can eliminate deep system conflicts that are not visible to the user.

Resetting app settings will bring all permissions, battery restrictions, and notifications back to factory status. This won’t delete your personal data (photos, contacts), but will force you to reset each app. To do this, go to Settings -> Apps -> All apps, click three dots in the corner, and select Reset App Settings.

If the problem is network-based (e.g., blocking updates or logging in to your account), resetting your Wi-Fi, mobile internet, and Bluetooth settings will help. path: Settings -> Connection and Sharing -> Reset Wi-Fi, mobile networks, and Bluetooth.

In extreme cases, if the lock is caused by a system failure or virus, a full reset to factory settings (Hard Reset) may be required.This action will completely delete all data from the phone, so be sure to back up important information before starting the procedure.

Complete discharge process:

1. Go to Settings -> About the phone.
2. Select Reset -> Erase all data.
3. Confirm the action with the password unlock the screen.
4. Wait for the reboot and the initial setup of the device.

Once the system is back to factory, the application lock problem should disappear, as all conflicting parameters will be removed. Install applications one at a time to track possible relapse.
