Jolla recently announced that their open source system Sailfish will soon be used on Sony mobile phones.
The first port should be Xperia X, which Sony exhibited in MWC 2017. Since Sony has always paid attention to open source system programs, Jolla said that he is cooperating with Sony to support Sony's open source device plan.
In addition, Jolla plans to release the community open source version of Xperia at the end of June this year.
