Sony Mobile is pushing a small firmware update for the Xperia C5 Ultra, moving the build number from 29.1.X.0.87 to version 29.1.X.0.101. The update is live on both the single SIM (29.1.A.0.101) and dual SIM variants (29.1.B.0.101), although only in select regions at the time of posting. For the dual SIM Xperia C5 Ultra, the update is live in the Nordics, Malaysia and Vietnam, whilst it is only out in Turkey for single SIM owners right now. The update should open up to more regions very soon.
In terms of changelog, the update includes the February Android security release, but little else has been noticed so far. Let us know what changes you’ve noticed in the comments below.
