In this article, we will look at all possible causes, from cache bugs to conflicts with system updates, and offer 10 proven solutions, including hidden settings and alternative methods for installing themes.

1. Reasons for departures of the application “Themes” on Xiaomi

Before you start fixing, it's important to understand why the application is unstable, and the main reasons are software and system:

• 🔄 Damaged cache – temporary application files may conflict with the new version MIUI orthodox.
• 📦 Update conflict – after updating the system or application, compatibility errors may occur.
• 🚫 Limitations MIUI — The shell blocks the installation of themes from unverified sources.

• 🔧 Google services are affected by some models (e.g, POCO X3) This leads to the collapse of the application.
• 🛠️ Broken theme files – if you downloaded the theme from a third-party source, it may contain errors.

In practice, most of the problem is cache or updates, such as when you switch to HyperOS, many users complain about crashes because the old version of the Themes app is incompatible with the new system architecture, and viruses or optimizers (such as Clean Master) can delete critical application files, which leads to crashes.

2. Basic solutions (without resetting settings)

2. Press and hold the “Off” option (or “Reboot” on some models).
3. Confirm the transition to safe mode.
