As a side note, you need to tap the text icon to select the text tool, then tap the page to start inserting text (your message was vague about whether you expected the keyboard to be shown after tapping the text icon). As a side note, there is also a mode where, if a stylus/pen is detected, it will let you write on a field on the screen and it will convert it for you. I'm assuming you don't have that enabled, and it shouldn't be activated if you tap with your finger.
