c# - Unity and native android keyboard

Question

I'm a newbie in Unity and my English is not perfect. I have a huge problem with the native keyboard numeric keyboard on android an inputfield. When I write numbers and press "OK" all is fine. But when I close the keyboard with "arrow" on the bottom of the phone text in inputfield is reset to empty. I found the code to fix it

[SerializeField] InputField inputField;
bool keepOldTextInField;
string oldEditText;
string editText;

void Start()
{
    
    inputField.onEndEdit.AddListener(EndEdit);
    inputField.onValueChanged.AddListener(Editing);
}
void Update()
{
    if (TouchScreenKeyboard.hideInput)
    {
        keepOldTextInField = true;
    }
}

private void Editing(string currentText)
{
    oldEditText = editText;
    editText = currentText;
}

private void EndEdit(string currentText)
{
    if (keepOldTextInField)
    {
        //IMPORTANT ORDER
        editText = oldEditText;
        inputField.text = oldEditText;

        keepOldTextInField = false;
    }
}

It works but now when I press the "OK" button on the native android keyboard text retreats by 1 character. For example, I type "200" and press "OK" and in inputfield is "20" for now. Please help me.
