Sony Xperia 10, mark 3 is very interesting mid-range device from Sony, but, as I already mentioned for same price, you can buy much more attractive or much more powerful smartphones. When you talk about support. This was always a big advantage of Sony Xperia devices, always the latest version of android operating system and monthly security updates as well. But when you talk about Xperia 10 mark 3 situations is not such perfect because till now only April 2021 security patch is for android operating system. And, yes right now, new update is available for Xperia 10 mark 3. But when I install it, I was surprised that many open information about this update still only May 2021 security patches.
So yes, as I mentioned, support, is always big advantage of Sony Xperia smartphones, but not this time because android 11 is refined but May 2021 is definitely not good.
