I have reset my 8X twice now and it seems that every time I get it set up (with all apps reinstalled) my "other" data goes over 5GB - and this is within moments of having all my apps reinstalled... We are talking practically NO usage as of yet - as in opening apps, browsing Internet, no caching, no photos/videos/music, no social sites/apps used, or even logged in and updated... This is kind of ridiculous as 5GB+ is over a 3rd of my "usable" capacity which SEVERELY limits my typical activity/usage coming from WP7, where all my installed apps music and other settings had much room to spare... I had hopes that Portico would help resolve some of this "phantom" data, but to no avail... Has anyone had any further luck in figuring out where/how this "other" data is occupying our devices??? It has my phone at less than 400MB available and limits EVERYTHING that I do...
