I've got the same thing. I signed up to this forum just to ask about this. You've got a Samsung Galaxy, right? So do I. I've had the issue since I got the phone, like a year ago.
Anyways something similar is documented https://discussion.evernote.com/topic/97615-evernote-android-typing-completely-glitchy/ but it's mistakenly marked as "answered". It is not answered, the issue has been around for at least 2 years.
I'm not sure how evernote can have a broken implementation of TEXT INPUT on (of all devices) SAMSUNG GALAXY, and it's been happening for YEARS. It's literally the most popular android phone.
