@@ -79,11 +96,13 @@ tbd
<p>If you have standard battery saving set up, when you start up OSMand and start recording a track, it will do a popup telling you about how to turn off battery saving.
<p>What you need to do seems to be correlated with how expensive your phone is. A Xioami Redmi 12 phone in 2024 worked with just the OSMand and battery saving fetures disabled as described above. But in 2025 a Blackview Wave8 phone would not produce a useable OSMand track at all until the "GPStest" app (see below) was also run continuously and with notifications and logging enabled.

<h3 id="temp">Temporary Google Photos</h3>
<p>When anyone shares photos on a "Shared Album" in Google Photos, they are only visible so long as the original photographer keeps the photos on their device: there are loads of photos by Harry Kettle from 2023 which are visible only as blank rectangles on the Shared Album because he has cleared out his photo album on his google account. (This really is a "share" not an "upload".)
<p>So unless the photo is utterly trivial and disposable, please also upload the photos using the <a href="/photoupload/">"Upload Photos"</a> page on the website <em>before</em> you delete them from your device.
<p>We would rather you didn't use Google Photos at all really, but people will willy-nilly, so let's at least use the <em>same</em> Google photos album each year.
