I'm noticing a few annoying differences in a couple of stock apps that come with Jelly Bean vs the "Old" ICS equivalents. The stock messaging app (ICS version) had an option to split and label a message into parts when it exceeds the text message limits. (ie. 1/8, 4/8, 7/8 etc...) This option seems to be missing from the JB equivalent. Also in messaging, I used to get punctuation suggestions at the end of a sentence. So if I needed to input a comma, I now have to switch to the numeric pad. Double space still inputs a period as it used to though. I guess I could switch to another keyboard, but that's besides the point. It was just a needless change I actually tried A.I. keyboard and didn't like some of the features. I guess I'll have to try Swiftkey.
