MSA on Xiaomi: what is it and why is it needed

Xiaomi smartphone owners often face a confusing process in the list of running applications, which is called MSA. This system component raises many questions, as it consumes battery life and Internet traffic. Many users immediately look for a way to remove it, considering it a virus or malware.

However, it is not necessary to rush to remove. MSA — It is not a virus, but an important part of the ecosystem. MIUI, Understanding how this service works will help you not only clear your memory, but also completely get rid of intrusive banners in the interface.

In this article, we will take a closer look at the function of this module, its impact on the performance of the device, and provide a step-by-step guide to safely shutting down the MSA, which is only possible after a 10-second wait in the confirmation window, and this knowledge is necessary for anyone who wants to make the most of their gadget without unnecessary visual noise.

What is MSA and why does the system need it?

MSA stands for MIUI System Ads, an integrated system service that is integrated into the MIUI shell and, according to the developers, designed to keep the advertising modules running, and it is through this process that you see banner ads in standard applications such as Explorer, Music, Security and Themes.

It's not just about showing images, it's about collecting anonymous statistics about your preferences to offer more relevant ads, and for the user, it's about analyzing which apps you run more often, and then generating promotional offers based on that data, and it's the company's main revenue stream, which allows you to sell smartphones at a low price.

Technically, the process is constantly hanging in RAM and periodically turning to servers to download new advertising campaigns, which can lead to a small but noticeable consumption of traffic and battery power, and if you do not use advertising, the operation of this module is useless to you and even harmful.

It's worth noting that global firmware versions (Global ROMs) often have a lower impact than Chinese versions, but it's not completely gone away, and it's driven by the manufacturer's business model.

The impact of MSA on the smartphone

The presence of an active System Ads process has a direct impact on overall device performance. While it may be invisible on today's flagships with a lot of RAM, on the budget models of the Redmi or POCO series, every megabyte of memory is in the account.

Also, constant data sharing with advertisers’ servers consumes mobile internet traffic, and if you have a limited plan, it can come as a surprise, and it’s also worth considering the energy consumption: even in standby mode, the processor is periodically activated to process advertising requests.

Disabling this component often leads to a subjective feeling of speeding up the smartphone. the interface becomes more responsive, and notifications stop coming from system applications with suggestions to install games or applications.

💡

After disabling the ad, it is recommended to restart the device so that the system completely clears the cache associated with the ad modules.

It's important to understand that disabling MSA won't disrupt the basic functions of the phone, that calls, messages, the Internet, and third-party apps will work normally, and you're just removing the layer that monetizes the device.

How to disable MSA through phone settings

The easiest and safest way to remove ads is to use the built-in shell settings. You don't need root rights or third-party software. The procedure is simple enough, but it requires care, as Xiaomi developers try to keep the user in their advertising ecosystem.

To start, go to the settings menu. Find password and security (in some versions Advanced settings). Next, select Access to personal data. In the list that opens, find the msa app and switch the slider to the "Off" position.

Here's the big nuance: when you turn off, you'll have a 10 second countdown timer, the confirmation button will only be active once the timer is zero, and many users don't wait for that moment and leave the menu thinking that the system doesn't allow you to turn off the function.

If you can't turn it off the first time, try to do it 3-4 times, sometimes it takes a few attempts before you agree to turn it off, and it's not a bug, but a feature of protecting against accidental or too easy shutdown of the ad module.

Disabling Advertising Personalization

In addition to directly disabling the process, it is recommended that the system not collect data about your preferences, this is done through MIUI Daemon service and advertising settings, which will not completely remove all banners, but will make them less intrusive and personalized.

Go to Settings → Password and Security → Access to Personal Data. Search MIUI Daemon and turn off access. This will limit the collection of statistics about how you use your smartphone. Also go to the Security app → Settings (cog) → Get recommendations and turn off this option.

You should check the settings of each system application separately. In Music, Themes and Explorer, you often have a "Get recommendations" switch in the settings menu. Turn them off wherever you find them. This is a comprehensive approach to cleaning up the system from excess junk.

💡

Comprehensive disabling of all advertising services (MSA, MIUI Daemon, recommendations in applications) gives the best result and maximum privacy.

After performing all the manipulations, it is advisable to restart the smartphone, which ensures that all background processes will be restarted with new parameters, and the old advertising IDs will no longer be used.

Comparison of Ad Blocking Methods

There are several ways to combat intrusive advertising, and they vary in complexity and effectiveness: some users prefer simple settings, others are willing to use more advanced methods such as: DNS-filtering ADB-team.

Below is a table that will help you choose the best method for your situation. Each method has its advantages and disadvantages that should be considered before starting an action.

Using a private DNS (e.g. dns.adguard.com) is a very effective method that blocks ads at the network level. This works not only in the system but also in the browser. However, if the DNS server is unavailable, you may have problems connecting to the Internet.

The most radical method is to use ADB (Android Debug Bridge) to completely remove system packets, which requires connecting to a computer and executing commands in the terminal, a method only suitable for advanced users, since an error can lead to unstable system operation.

Possible problems and solutions

Users may encounter a number of difficulties in disabling system services, most often the problem is that the slider in the settings simply does not want to switch or returns to its original position, which is a normal reaction of the MIUI protection system.

If the standard method doesn't work, try to turn off the Internet before entering the Access to Personal Data menu. Sometimes blocking network connections prevents the license status of the ad module from being checked, and the system allows you to change the setting. After a successful shutdown, the Internet can be returned.

⚠️ Warning: Do not attempt to delete system files through root-right file managers without a full backup.Removing critical system libraries can result in a device bootloop (cyclic reboot.

Also, you should consider that after a major firmware update (for example, switching from MIUI 13 to 14 or HyperOS), the settings may reset, in which case the procedure for disabling MSA and other services will have to be repeated again.

If you notice that the battery has run out faster after the manipulation, check the usage statistics. Maybe some other process has started to compensate for the lack of an ad module, trying to gather analytics in other ways, in which case the installation of a firewall will help.
