Samsung S6 and Subaru Forester

[VintageGirl40s]

I have an HTC One M8 that is phenomenal, musically (Forester 2014 2.5i Touring), but stinks re. texting. I tried out a Samsung S5 (which was very lacking musically) that allowed me one touch SMS texting - it would listen to my voice dictating the text, read it back, then send the text - like magic! Just one touch. The Subaru chart has not updated to Samsung S6 and I would like to purchase one.... can ANYONE advise me if the S6 will ALSO let me completely send and receive and text using ONE TOUCH. Please note: I am NOT just referring to basic texting / Bluetooth.
Very few phones are one touch compatible with Subaru,

which is to Subie's discredit.... Please update the firmware (software, whichever).
Thank you so much!
