Wild readings after upgrading Galaxy S6 to Android 5.1.1 Used this app for 2 years without issue. After Android reflash and upgrade to 5.1.1 am getting wild results when logging that seem to have the GPS fixes jumping all over the place  e.g. Aberdeen Scotland one minute and London 30 secs later  a difference of over 600km. Never had this before. As a registered blind person I use this to log my train journeys and track them on Google using my PC later. Any help to fix what was a really enjoyable experience is much appreciated. Thanks.
