Took me like 5 seconds on Google to find out that Mediatek has only ever released source code for the "Android One" series of devices and that because they did this in a partnership with Google themselves they were most likely forced into doing so.Took me like 5 seconds on Google to find out that Mediatek does release source code, though they didn't previously so you're operating on old information
Agreed. The Chinese chip designers are poison for the market too, in the long term.Don't do it Samsung! Mediatek is not good for the smartphone ecosystem
Stick with Qualcomm until 2016 when AMD starts releasing their own ARM chips for smartphones. Stay away from Mediatek, Rockhip, Amlogic and Allwinner!
