My iphone screen stops when i'm typing "donghocat". Iphone 13 pro max

You are typing this in which app? What is your device's iOS version?

It sounds like you're describing an issue where typing a specific string, "donghocat," on your iPhone causes the screen to freeze for around 10 seconds. This behavior is not typical, and it might be related a third-party app, or some other underlying issue. Here are a few steps you can take to troubleshoot and potentially resolve the problem:

1. It's possible that there's a corrupted entry in your keyboard dictionary causing this issue. Go to Settings > General > Transfer or Reset iPhone > Reset > Reset Keyboard Dictionary. This will erase all custom words you've added, but it might help.
2. Certain third-party apps might be causing conflicts. Try typing "donghocat" in different apps and see if the issue persists. If it only happens in specific apps, consider uninstalling and reinstalling them.
3. Sometimes, a simple restart can resolve temporary software glitches. Turn off your iPhone, wait for a few seconds, and then turn it back on.
   1. Restart the device. That's it.
   2. Still not solved --> Force restart iPhone - Apple Support
4. If the issue persists, you can try resetting all settings on your iPhone. This will not erase your data but will reset all personalized settings to their default values. Go to Settings > General > Transfer & Reset > Reset > Reset All Settings and confirm the action. Note that you will need to reconfigure your settings afterward. All settings—including network settings, the keyboard dictionary, the Home screen layout, location settings, privacy settings, and Apple Pay cards—are removed or reset to their defaults. No data or media are deleted.
   1. Reset All Settings: Return iPhone settings to their defaults - Apple Support:- Return iPhone settings to their defaults
   2. You can return settings to their defaults without erasing your content.
   3. If you want to save your settings, back up your iPhone before returning them to their defaults. For example, if you’re trying to solve a problem but returning settings to their defaults doesn’t help, you might want to restore your previous settings from a backup.
5. Make sure you have the latest updates installed.
   1. Update Over-the-Air (OTA) —> Update your iPhone or iPad - Apple Support (IN)
   2. Update using iTunes/Finder —> Update your iPhone, iPad, or iPod touch - Apple Support (IN)

If none of the above steps resolve the issue, it is recommended to reach out to Apple Support or visit an authorized service center for further assistance. They can provide specific guidance based on your device model and iOS version.
