<p>Phones assume that you are walking along streets, or running along tracks or cycling. They are very bad at making the right guesses for the Totes Gebirge plateau.
<p>Do <em>not</em> select the "high accuracy" location setting on your phone. Mostly this will snap your position to the nearest cafe or bierstube: by default it will use the nearest WiFi it can find and assume that you are there, and will ignore the perfectly reasonable GPS position it has recorded directly.
<p>This is all explained by Google <ahref="https://support.google.com/maps/answer/2839911?hl=en&co=GENIE.Platform=Android">here</a>.
<p>On the plateau, this "high accuracy" mode will simply give you the <em>wrong</em> position if it can't get a decent GPS fix. There is poor cell tower reception too, so trying to use that for location is just as bad.
<p>What you want is GPS and <em>only</em> GPS (more precisely <ahref="https://en.wikipedia.org/wiki/GNSS_applications">GNSS</a>: which includes GPS, Glosnas, Beidou, Galileo etc.).
<p>If you do not have a good GPS fix, <em>you want to know that</em>, not be given some confabulated guesstimate by whatever some programmer for Apple or Android thought your might want.
<p>When you share photos on your phone to the Expo photo sharing site, by default, the location of those photos will be stripped out. So all those lovely pics of intriguing cave entrances you snapped on your walks are now utterly useless.
<p>So, before expo, perhaps while sitting in a traffic jam around Munich or on the train from Bad Ischl, take a moment to photograph your travel companions in an embarassing pose and fix the this:
<p>If recording a track, you do <em>not</em> want your phone to decide to go into "energy-saving mode" (the default if you are not actively interacting with your mapping app, such as OSMand) as it will drop location points and your recorded track wil now gaily bound over impenetrable chasms, rendering it rather useless for finding your way home in thick cloud.
<p>Unless you have already done a couple of days with your phone set into "continuous GPS mode", you have no idea how long your battery will last. So if you haven't already practiced this on a fell in the UK, you need to <b>bring a phone backup battery</b> with you on expo.
<p>You can buy phone battery backups in Austria, but they are a bit epxensive, and hard to find in Bad Aussee (try the post office phone shop, or the deviously hidden electronics repair shop in central Bad Aussee).
<h4>How</h4>
<p>detailed instructions depend on the type of phone and the version of Android - someone fix this ?!
