I wasn't expecting to be so happy from an iOS update but this last one fixes something huge for me. Before the update everytime my partner or bandmate or friend sent me a message, Siri would say...

"So-and-so sent you a message that I can't read"

Yesterday after the update, Siri read all the Japanese messages in Japanese. It was such a relief. All that info that I usually had to pull the phone out to read was "magically" in my ear.

You don't notice a lot of updates but when they get around to one that affect you, it feels amazing.
