Yes I have note fields in in all my contacts. Some have numerous amount of characters in each note field and others very little. In fact the majority of my contacts have a large amount of notes in them and there is NO WAY to add more from the S4. So just now I have found my answer..... by adding more notes to a contact on my S4 which had only very few characters of notes worked fine until an eventual limit was exceeded and I could not add any more notes. This was not the case with my Samsung Galaxy Nexus. TRULY THIS IS A REAL PAIN. I would probably have purchased a Nexus 5 had I known this would have been an issue.
