If this sounds familiar to you, don't worry you haven't read this story before. Back in October 2015 Sony introduced an Xperia Marshmallow beta program, which was more of an experimental concept of Marshmallow and not a pre-release of the Android software. This means that even though participants of the beta test program might be the only ones to enjoy that specific version of Android on their Xperia handsets, the soon to be released beta version is still in the early stages of the Marshmallow OS and will be made available to everyone shortly.Android 6.0.1 Marshmallow beta firmware is currently being released to the Xperia Z2, Xperia Z3 and the Xperia Z3 Compact. The same version of the software will be rolling out soon to all other Xperia owners, once all the bugs have been addressed and everything else is stablized to satisfactory capacity. This is expected to start with much newer Xperia devices and trickle down to older and mid-range handsets.Though Sony introduced this program a month ago for Xperia users in the Netherlands, Italy and Spain, this is the initial beta firmware under the new test program to be pushed out. The Andoid 6.0 update has already been rolled out to the Xperia Z5 variants as well as the Z3+, so this is an incremental software upgrade compared to the latest update made available to the public.The Android 6.0.1 beta firmware comes with a build number of 23.5.A.0.486. The new firmware brings features such as an additional launcher combined with a search function in the app drawer, a newly introduced Camera 2.0.0 interface similar to the one found on the Xperia Z5 series, as well as the elimination of the STAMINA mode. It also gets rid of the app drawer and it does not embrace the option of adoptable storage.What are your thoughts on the Xperia range Marshmallow versions? Lets us know in the comments.
