Browser fragmentation SUCKS. So does debugging and optimizing for the heavily fragmented web on mobile. Jay is going to cover a number of approaches to check consistency and performance of code in production across multiple mobile operating systems and browser engines. We'll nail down the best approach to interpret analytics targeting the right farm of test devices - and how to acquire them for free! - as well as the right tools and tests for your job. At the end of the session you'll either walk away with an ideal starting point, important additions to your existing QA workflow - or as part of the glorious few that knew it all and shared their genius with others.
