I enabled Google services in one profile in order to use the keyboard.

But that keyboard makes network calls to Google. Because it needs to predict the next character based on context. One sound makes hundreds of characters you have to choose from.

Privacy is already lost and by using Google services you lose battery life because grapheneOS has an extra layer that drains the battery.

It just isn't practical yet if you need asian language support.

Plus none of my banking apps worked.
