Call audio quality after update?

[Lagos]

So since the recent update, I noticed that the call audio quality is MUCH better than it was before. Everything sounds more clear and detailed than it used to, and even my girlfriend said that she can hear me more clearly than before.

Have any of you guys noticed the same thing? I believe improved audio was on the list of things addressed by the update.

To me it sounds the same. In my opinion.

Of course I'm rooted, so I haven't gotten the latest update as of yet.
