I'd be more than happy to assist you. Unfortunately the contact notes section is an Android limitation not a phone specific limitation. The best you could do is use a 3rd party app like one of these: https://goo.gl/N2697d or https://goo.gl/C8KSI4
You may be right about that though I was pretty sure it was an Android limitation. Would those apps be a good workaround? Or were you looking for a different method?
I'm not familiar with DejaOffice but I did a quick search and it appears it does sync notes as well
I apologize we may not be on the same page, it happens from time to time. Here's what I will do, I'll opt-out of your question and let another expert step in to assist.
