Earlier today Google started rolling out update JSS15Q for their Nexus 7 devices that included a fix for the 2013 model to address problems with touchscreens. We now have confirmation from Google that this latest update also corrects GPS problems that some users were having.
The GPS problem would cause the Nexus 7 to lose the GPS lock after prolonged use of the GPS capability, especially in cases where a users was switching between several apps that use GPS. Considering all of the apps that are interested in a device's location, it was quite easy to overwhelm the GPS code.
The update is still slowly rolling out to Nexus 7 owners. Other than the information gleaned from the support forums, Google has not released any official word on just what JSS15Q includes. We also continue to wait for Google to make the update available for download for those users who have moved on from stock and may not get it through the regular OTA method.
