If I am honest I am not finding using the Xperia S a pleasurable experience these days - the camera takes about 20 seconds to open sometimes, meaning a photo opportunity could be gone, and also whichever app I use, when I go back to my homescreen, it has to re-draw itself pretty much every single time, and I can't do anything with the phone until it's finished loading icons and re-drawing the screen! It just seems slow and sluggish, and it doesn't feel like a phone that's only a year and a half old. I've used a friends Samsung Galaxy S2, a phone a year older than the Xperia S and of a lower spec, and there are never any hang ups, slow downs, re-draws, stuttering of music or apps, even on Jelly Bean. Everything just moves so smoothly! My phone at the moment feels pretty unuseable at times, even as a phone! And there are times when you drag your finger across the screen and it takes forever to react. I don't know what Sony do to their phones/software, but it just feels like the phone isn't performing to its potential - I don't think I've ever seen the best of this phone.
It does disappoint me that Sony seem to have something against the Xperia S - they weren't even going to give us Jelly Bean, and the wait to finally receive the update was ridiculous. But you'd think in all that time that they would have been able to produce a polished update, but no, it's worse than it was when on ICS!
Thanks for looking into this situation. I have been told that O2 are doing "testing" on the new ROM release, but what testing needs to be done? Seems like a poor excuse to me. Even if there were problems with the ROM, it's not like O2 would be able to fix them, plus other networks have released this update, which would indicate there are no issues, so why are we still waiting?
Cheers
