A couple of days ago, more precisely on December 14th, Wi-Fi Alliance listed a couple of certification documents for three Sony Xperia devices. Among them we have the Xperia Z4, Xperia Z5, and the Xperia Z5 Premium – world’s first 4K phone. Well, the novelty revealed by these documents, is the fact that all these models are running Android 6.0 Marshmallow.
From the information revealed, it seems that all these phones are Japanese variants, sold through the NTT DoCoMo mobile operator. There’s Xperia Z5 SO-01h, Xperia Z5 Premium SO-03h, and the Xperia Z4 SO-03g.
Taking in consideration all these certifications received by the phones above, we could expect to see the new software pretty soon on our phone, in this case – Android 6.0 Marshmallow. As you already know, Xperia Z4, Z5 and Z5 Premium share an octa-core Qualcomm Snapdragon 810 processor, and 3 GB of RAM memory.
