I can’t type the number twenty on iOS

Since upgrading to iOS 15, I can no longer easily type the number 20. iOS automatically replaces it with 2.0, as shown in the screenshot. I don’t have a Text Replacement that would do this. Is this happening to anyone else, and is there a way to fix it?

Additional information: this is also happening on my wife’s phone. I used the search function to search for “2.0” on both of our devices, and we both have an app named “RTAGoMobile2.0” installed. I tried removing that app and Reset Keyboard Dictionary, but this behavior has not gone away.

iOS adds installed app titles to your autocorrect keyboard dictionary as part of the QuickType keyboard system. A lot of people realized this when MARIO RUN came out on iOS. So the problem was probably originally caused by the RTAGoMobile2.0 app.

Since removing the app and resetting the keyboard dictionary didn't work, here are two two other things you could try:

1. You can train the keyboard to unlearn the correction by repeatedly typing "20" and tapping the x to remove the "2.0" suggestion.
2. You can add "20" as a text replacement, with "20" as both the phrase and the shortcut. Apple documents how to do that here:

With text replacement, you can use shortcuts to replace longer phrases. When you enter the shortcut in a text field, the phrase automatically replaces it. For example, you could type "GM" and "Good morning" would automatically replace it.

To manage text replacement, tap Settings > General > Keyboard > Text Replacement.

• To add a text replacement, tap plus icon, then enter your phrase and shortcut. When you've finished, tap Save.
• To remove a text replacement, tap Edit, tap "-" then tap Delete. To save your changes, tap Done.

If you type out 20 20 20 20 20 and cancel the suggestion carefully each time, that might reset the learned database on the device that thinks it’s being helpful.

Also, I learned after posting this all app names are added to the “auto wrong” database, so you might struggle to “unlearn” those.

A good way to flush the predictive text on iOS 15 is the Reset Keyboard Dictionary tool in settings -> general

Once that is done, try to break the training by not accepting the correction. Also, check other devices you have signed into the same iCloud account in case these hints are shared between devices.

None of my devices do that for 10 or 20 or 30, so it’s likely trying to be helpful based on what you typed in the past and not something hard coded. Hopefully, you can dutifully correct the error each time it happens and the adaptive code will unlearn that “correction”. Sometimes auto correct feels more like auto wrong.

Unless Apple is pushing these “suggestions” from the server, you should be able to wrangle it. If not, a call to apple support might be needed - especially if they are seeding the corrections based on region or usage in general.
