I've just bought a new Sony x7500f and I've been hunting round the web to try and answer a few questions I have but I seem to be coming up short...

I am a big fan of Android on a smartphone but the version on my Sony seems incredibly locked down. I don't even seem to be able to do simple things like change the awful brown homescreen background or set up a folder of photos to run as as a screensaver. Am I missing something here or is there some way around it?

Thanks!
