How to turn off the automatic capital letter on Xiaomi smartphones: the complete guide

Are you tired of Xiaomi automatically capitalizing at the beginning of each sentence or after the dot? This feature is useful for business correspondence, but interferes with logins, hashtags or program code. In this article, we will examine all possible ways to disable autocapital letters on Redmi, POCO and other Xiaomi devices – from standard settings to hidden developer settings.

The problem arises from the aggressive autocorrection policy in the Mi Keyboard and Gboard keyboard, which the manufacturer believes that the user always needs "beautiful" sentences with a capital letter, but in practice this often leads to errors. For example, when typing commands in Terminal or writing code in Python, extra capital letters can break the syntax.

  3. Select Text Input → Autocorrection.
  4. Turn off the capital letters switch at the beginning of the sentence.

⚠️ Note: After disabling this function, the keyboard will stop correcting all automatic capital letters, including proper names (for example, "Moscow" instead of "Moscow.

  2. Click Add a word and enter a term (e.g., "python" or "github").
  3. Save it with a note always with a small letter.
