We announced at launch that the Xperia 10 VI would receive three Android OS upgrades. However, after a detailed technical assessment, we determined that due to limitations related to the device’s storage configuration, the Xperia 10 VI does not support an Android 17 upgrade experience that we consider adequate. Accordingly, we have decided not to make this upgrade available.
No, seriously, after tasting GrapheneOS, going back to any device that doesn’t support it feels not just like a step backwards, but more like a leap face down from a skyscraper (the skyscraper one might be more enjoyable for a few secs, actually). This kind of BS from Sony is one of the reasons.
Your Pixel gets new GrapheneOS releases because Google keeps pushing Android releases for it.
Sony is one of the few other remaining phone manufacturers which still allow 3rd party OSes and release sources. So this matters for LineageOS users. Graphene is not the only one.
