Automatically swapping the first letter for a capital in messages or search queries is a useful feature for most users, but not for everyone. On Xiaomi smartphones (including Redmi and POCO models), this option often works too aggressively: it fixes the register even in hashtags, nicknames or technical terms where it is not necessary. Worse, on some versions of MIUI, it is impossible to turn it off through standard settings without additional manipulation.
In this article, we will analyze all the current ways to deactivate autocapital letters on Xiaomi, including hidden keyboard settings, ADB-Notice that the methods vary depending on the version of the system files. MIUI (12/13/14/15) We also tell you how to return the settings back if you have problems typing after you turn off.
Why does Xiaomi force capitalization?
Auto-capitalization is built into Android and MIUI as part of the autocorrection system, and it works according to three basic rules:
- 📱 After the dot/exclamation point: New phrase begins with a capital letter.
- 🔠 At the beginning of the input field: the first letter in the message, search query or address is always capitalized.
- 🏷️ For “important” words: proper names (Moscow, Xiaomi), days of the week, months.
On Xiaomi, the problem is compounded by the manufacturer modifying the standard Android keyboard by adding its own algorithms. In MIUI 14, for example, autocapital letters can fire even after @ in email or # in hashtags, which annoys Twitter/Instagram users. Moreover, on some models (for example, Redmi Note 12 Pro+), the setting is hidden in the depth of the menu or is not at all in the graphical interface.
