Slight ramble / off topic, I’ve owned a few Sony phones over the years, granted this was some time ago bit they were my go to here in the UK before they decided to add too many digets too the price, my last one was an Xperia 10 (I think, Sony’s naming convention and all that) great phone at the time, headphone jack and microSD cards, nice toolless SIM tray (which the still do I believe), spec sheet was decent etc.
But one thing I did not manage to notice while doing my research was the performance was god aweful in Sony’s android implementation at the time (at least on the 10) the underlying OS was so poorly optimised it kind of fell inside its own arse whenever doing anything more taxing than watching a video, everything surrounding it was perfect but the software.
Great phone held back by poor software, many years late I flashed Linage and rocked it as a dedicated music player, with my wired headphones and 128GB microSD and it was night and day.
On an unrlated note, I still kind of miss old Sony design language in their OS that kind of mirrored XMB in some ways especially the UI sounds and icons, but anyway the battery was going on it years ago and I lost it during a move, I still miss that phone.
