Ok this is SOLVED!!! Yeaaaa!!
After I updated, Siri and Dictation quit working and only worked on Bluetooth!
I tried everything and spent days researching it on the web and no one knew anything!
I checked all the settings, I tested the memo mic and the main camera mic and all worked good. I even reset my phone as a new phone without using the backup! No use! I was positive it was a software issue and it was... More or less.
Turns out that the selfee mic IS the problem, it's the mic on the screen side of the phone near the camera. And it's not the same one used for memo recording that's on the bottom!
Maybe my phone used more than one mic or a different mic for Siri and Dictation before the update, and then after the update used only the Selfee mic... I don't know, but I bought a camera and mic combo part and a pentalobe screwdriver to get the screws out and changed it my self.
And BINGO! no more Siri and dictation problems. WHEW!!!
