Lumia 520 lagging? Here's my fix...

... Just turn off Cortana. This may be a big turn off for some really looking forward to her (i personally didn't see that much added value - then again Siri isn't exactly useful either), but my 520 is back to silky smooth without her. I like my Bing search anyways.

I think I'd deal with the lag rather than turn off Cortana! Fortunately my 520 doesn't have that problem.
