Greetings, kotrynafromlondon.
I see that you're using the Lithuanian keyboard for your iPhone 7. The problem is, it isn't displaying the correct letters. I'm happy to help.
Use international keyboards on iPhone - iPhone User Guide
Enter accented letters or other characters while typing
While typing, touch and hold the letter, number, or symbol on the keyboard that’s related to the character you want.
For example, to enter é, touch and hold the e key, then slide to choose a variant.

You can also do any of the following:
- On a Thai keyboard: To choose native numbers, touch and hold the related Arabic number.
- On a Chinese, Japanese, or Arabic keyboard: Tap a suggested character or candidate at the top of the keyboard to enter it, or swipe left to see more candidates.
Note: To view the full candidate list, tap the up arrow on the right. To return to the short list, tap the down arrow.
About the keyboards settings on your iPhone, iPad, and iPod touch -- If this keyboard isn't meeting your needs, you can look for another Lithuanian keyboard that does.
You can install third-party keyboard apps just like you install other apps on your device. After you install a new keyboard, you need to add it before you can use it. Follow these steps:
- Go to the App Store and find the keyboard app that you want.
- Tap Get > Install.
- Enter your Apple ID password or use Face ID or Touch ID if it's available on your device.
- Then add the new keyboard. Go to Settings > General > Keyboard > Keyboards > Add a New Keyboard and select the app that you installed. You might need to set the keyboard to allow full access in order to use it.
To delete a third-party keyboard:
- Go to Settings > General > Keyboard and tap Keyboards.
- Tap Edit.
- Tap
, then tap Done.
You can also delete a keyboard by deleting the companion app that you installed from the App Store. This also removes the keyboard from Settings.
Take care!
