Just last week, Sony rolled out the Marshmallow update for Xperia C4 and continuing the trend, today, Sony also issued the same version of Android update for the newer Xperia C5 Ultra. The Xperia C5 Ultra is more than just an upgrade for the C4 but also an upsized successor with a large 6-inch display and has carried over the best Selfie-centric experience from the C4.
The said update carries a firmware number 29.2.B.0.122 for the Xperia C5 Ultra E5533 dual-SIM variant. The firmware is currently available in Italy and should be rolling out in other regions as well in the coming days. Just in case you’re not fond of waiting, you may also check for the update manually by going to the Settings menu on your phone.
