Although one thing I hate is that when you're reading the messages you recive on the phone the time still increases, it would be nicer if it would pause or something.
Guys if you are having a hard time telling which chars are yours then look at the top right corner of your screen, there you will find the facial icons of all your team-mates and their HP, then just roll over any character on the field and you'll be able to tell which one is which by their facial icons. (I'm just posting this to all the ppl that are having a hard time figuring out which char is on which side)
