Default [Q] App for Input and Clipboard

Hi everybody,

is there a specific systemapp for text input?
I don't talk about a keyboardapp.
I'm talking about an app which gives you controls about the inputcursor in texts and lets you mark texts.
Sometimes there is also an magnifying glas when movin the cursor.
I have a rom with obviously that app broken. So i can input texts but cant move the cursor.
Always force close when moving the cursor or longpressing on a text.

Does anyone have an idea?
