Earlier this month, Sony finally started to send out the update to Android 6.0 Marshmallow for the devices in the Xperia Z3 family, with one notable exception - the Z3 Tablet Compact. Back then the company didn't say anything about the Marshmallow release for the slate, which understandably angered its owners. But all's well that ends well, as they say. Today the rollout of the new Android iteration has started for the Xperia Z3 Tablet Compact as well.
The new build coming your way over-the-air has the version number 23.5.A.0.570. It's currently making its way to both LTE-capable variations of the tablet (model numbers SGP621 and SGP641), and also to those with Wi-Fi-only connectivity (SGP611, SGP612).
Obviously it might take some time before the rollout is complete and the update reaches all Z3 Tablet Compact units out there. What's more, it's probably phased depending on market and carrier, so where you bought your tablet could influence how soon you see Marshmallow running on it.
Move forward and buy one that has it, plus your info has Not been verified and anyone can posts gibberish on these feeds. Just read most of this junk posted. Haha
Yes I remember that. I never particularly liked Vaio machines anyways. It's telling that the only profitable business Sony is in is the PlayStation. Oh and possibly their camera sensors but I don't know enough about that.
