It is one of the mobile manufacturers that have been growing over the years, operating in a market where competition is fierce. Xiaomi has been launching different models of its series to supply to the different countries in which it operates, both in Europe and outside of it.
Xiaomi has a large catalog of mobile phones, ranging from the most basic to the most powerful, with its Xiaomi 12 series as the total protagonist. Xiaomi has been wanting to unbrand the main brand of Redmi, although it is worth mentioning that they usually share some things, design and sometimes even specifications in several models.
Surely you have seen a specific error if you are the owner of a Xiaomi phone, specifically one that says «MSA has stopped working». Despite not being too common, it is one of the errors that appear at an inopportune time, but it has several solutions if it has appeared while using the mobile.
What is the MSA?

MSA is an application installed on Xiaomi mobile devices, specifically it is called MIUI System Ads (Xiaomi ad service). It is a system tool, it cannot be eliminated at any time, although we can go to it to try to solve any problem if it throws an error.
The MSA utility usually shows a few ads throughout the use of the phone, it is something that this brand has been doing for a while. The person will be able to restrict it, always managing to locate the application, which is quite hidden, at least in view of all users.
End this app by going to the route, the only thing is to revoke and deactivate this function, which in the end will not be worth more than seeing ads from time to time. The MSA can be overridden, which will eventually let go of annoying ads on different parts of the phone.
Fix “MSA has stopped working” error

Although it seems complicated, It's pretty easy to fix "MSA has stopped working" error. Behind this problem is WebView, a module of the Google Chrome browser. If WebView is not working properly, it will show this error, which greatly affects the phone and will give this message on the screen.
Finding a solution is effective and fast, not having to reset the system, and the person has several solutions if you want to repair this. It appears in the different phone models, included in the latest releases, so don't be surprised that it shows up in yours later.
To fix this, you have to fix Android System WebView errors, which will be done as follows on your device:
- The first thing is to check that you have the latest version of Google Chrome, you can access the Play Store and review this, tap on this link
- Check on the other hand to have the latest version of WebView, it can be installed from the Google Play store, lower the same from here
- After updating the two applications, restart the mobile device and wait for it to load, the error will not appear again, although you have the possibility to quickly disable it from the settings
Do the following step if you see that the error returns on your Xiaomi:
- Tap on “Settings” and then go to “Applications”
- Click "Show All Apps"
- Search for “Android System WebView” and click on “Settings”
- Hit stop "WebView" and uninstall any update
- Restart the phone and use it normally, check that you don't see "MSA stopped working" in a message on the screen again
Remove ads from any Xiaomi terminal

One possibility to override the MSA is to stop it in your smartphone settings, it will prevent you from seeing any ads and thus avoid seeing the message “MSA has stopped working”. If you have MIUI 12 or higher (or lower), this solution will work on phone models with this layer.
MSA is a system application, an advertisement service devised by the manufacturer, giving the ability to sell certain terminals at a lower price by taking advantage of this advertising space. The person will admit this, although it is true that he will be able to end it when required and not having to respect what Xiaomi says.
To stop MSA ads, do the following steps:
- The first thing is to go to “Settings” on your mobile phone and wait for it to load all the options
- Go to “Passwords and security”, inside here go to “Authorization and revocation”
- It will load you with a large list of services, locate one called “MSA” and uncheck the option to remove it
- We will get an alert that the application could be unusable, something that does not have to worry us in any way, since the ads are not important at all throughout our use of the phone
- Let the countdown reach about 10 seconds and click on “Revoke”, making the MSA service deactivated and does not show more ads throughout the use of our device, it is ideal that it does not do so if we want to be safe from annoying advertising
Enable MSA if disabled

After you have learned how to disable the MSA, if you want to re-enable it, it is best to learn how to do it manually, as the app cannot be enabled automatically. With its activation you will see ads again, they will be few, despite this they will be annoying if you are not used to it.
Enabling it may also fix WebView issues again, as long as it prompts you to turn this phones internal setting back on. MSA in the end serves little more than to offer direct advertising by Xiaomi, which usually shows small banners.
To enable MSA, do the following on your device:
- Go to “Settings” and then go to “Applications”
- Find “Android System WebView” and tap on it
- If it shows disabled, hit “Enable” and update the application in the Play Store, you can do it from this link
