I guess with this latest Android 4.3 Jelly Bean update, you can kiss goodbye to the irritating, erratic performance of multi-touch functionality on the new Nexus 7. Do bear in mind that this particular issue only arose after the second OTA JSS15J was installed on the new Nexus 7 (2013). While there is a number of Nexus 7 users (whom we do not know how many exactly) that are going through issues with GPS on their new Nexus 7, it remains to be seen whether Google has already fixed the GPS issues with the same update.

The same Google representative, Paul Wilcox, confirmed the GPS fix in the same update in another thread:
Thank you for your patience while we’ve been working on this. As Justin mentioned, there is a new over-the-air update for Nexus 7 rolling out now that addresses the GPS issue discussed here. We look forward to hearing feedback about your GPS experience after you’ve received the update.
