  • โŒ Typographical statements you have confirmed (e.g., โ€œhelloยป โ†’ ยซquiverยป).
  • ๐Ÿ“ฑ Words from other applications (messengers, social networks, games).
  • ๐Ÿ”„ Outdated data (such as old passwords or nicknames).

Over time, this โ€œgarbageโ€ accumulates and leads to problems:

  • ๐Ÿข Slowing down the keyboard โ€“ due to an overloaded database.
  • ๐Ÿค– Incorrect clues โ€“ for example, instead of โ€œsalvationโ€ offers โ€œsalvationยป.
  • ๐Ÿ”’ Leakage of confidential data โ€“ if you sell a phone, the dictionary may have logins or addresses.

How to prevent dictionary clogging in the future

To avoid cleaning the dictionary every few months, follow these tips:

1. Turn off typo saving

In MIUI Keyboard, go to Settings โ†’ Text Input โ†’ Auto Replace and turn off the Save New Words option. In Gboard, this is done in Settings โ†’ Text Correction โ†’ Auto Replace.

2. check the user dictionary regularly

Open the User Dictionary once every 1-2 months and delete unnecessary words (especially typos) that will take no more than a minute, but save time in the future.

3. Use the word blacklist

In Gboard, you can add words to Exceptions (Settings โ†’ Dictionary โ†’ Exceptions) so that the keyboard never offers them, such as mat, slang, or outdated terms.

4. Sync the dictionary with your Google account (optional)

If you change phones frequently, turn on sync in Gboard (Settings โ†’ Dictionary โ†’ Dictionary Synchronization) to allow you to transfer frequently used words to new devices, but be aware of the risks of data leakage.

If the keyboard slows down, check the app cache and free space in the phoneโ€™s memory (less than 10% of the free space can cause lags).

FAQ: Answers to Frequent Questions

Can you clean a dictionary for just one language?
Yes, in Gboard, you can delete words for each language. Go to Settings โ†’ Dictionary โ†’ Custom Dictionary, select the language you want and delete unnecessary words. MIUI Keyboard doesn't have that option - cleaning affects all languages.
Will the dictionary be cleaned when the phone is reset to factory settings?
Yes, when you reset completely (Settings โ†’ Additional โ†’ Settings Reset), all data, including the user dictionary, is deleted, but if you sync with Google, words can be restored after you log in.
How to transfer the dictionary to the new Xiaomi phone?
If you use Gboard, enable dictionary sync in settings (Settings โ†’ Dictionary โ†’ Dictionary Synchronization). For MIUI Keyboard, no dictionary transfer is provided - you will have to type frequently used words again or use a backup via MIUI Backup (but this will transfer all the phone settings, not just the dictionary).
Why did the keyboard start offering strange words after cleaning the dictionary?
This is a temporary phenomenon โ€“ it takes 1-2 days for a keyboard to learn your writing style, so to speed up the process, manually add frequently used words to a userโ€™s dictionary or turn off auto-replacement for that time.
Can you clear the dictionary without accessing settings (e.g. if the phone is locked)?
No, without unlocking your phone and accessing settings, you can't clear the dictionary. If the device is locked, the only option is to reset via Fastboot (but that will delete all the data!).
