4 Best Apps For Applying Custom MTZ Themes On Xiaomi, Poco, Mi & Redmi

For those who know, or don’t know, Xiaomi phones have some features that not every phone has, like downloading and applying a theme to the phone by using its official theme manager app.  But in some cases it is not possible to find good themes in it, that’s why some 3rd party theme developers are creating good themes that you can download and then apply it in the miui version of your xiaomi from MI itself.  , to Poco and Redmi.

The thing that prevents you from getting good 3rd party themes is one to two reasons, Xiaomi theme manager doesn’t like the app that is similar to other phone brands because of copyright, I know some people don’t understand me when I say themes on the phone.  The themes are similar to the launcher but they also have many differences and among them, the launcher slows down the phone a lot and the actual launcher app is not from the original phone company.  But if it’s a theme manager, each phone has its own system, it’s better if your phone supports the theme manager app, just use it, you don’t have to download it anywhere. Go to the phone menu or setting and find it, Because of improvement or fixing bugs, you have to update the theme manager that your phone comes with on a regular basis.

After that, since you have come to this page to get information about 4 apps that will allow you to install a custom .mtz theme file.  All xiaomi phone models use .mtz unlike huawei phones whose custom theme file name they use is .hwt.  For example, if Xiaomi is running MIUI and the theme file name is similar to xxx.mtz, ‘xxx’ is the file name, and .mtz is the extension.

Also in Huawei EMUI xxx.hwt is the file of every theme, at the end of this post you will understand how to use these apps to install any kind of theme you want easily on any kind of MIUI version phones.

4 Best For Applying Any MTZ File On Xiaomi Model

MIUI Theme Editor

This is one of the main app that is developing or editing any theme in MIUI Xiaomi models, and it gives access to cool or any other 3rd party themes in your Mi, Redmi or POCO phone.

What I am going to explain is how you can attach any kind of MTZ theme file to this app on your Xiaomi Miui version phone.

Miui theme editor is available on your playstore, and you can download or buy its premium version on internet search.
