Newer versions of Android OS try really hard to save power - which meant that the phone wouldn't wake up when it was supposed to do on Android OS > Jelly Bean (4.3). Have now tested on our 'reference' phone the ZTE Blade A110 running Android 5.1 (Lollipop/22).
The interface has been updated to include features such as 1) 'walking mode' that will beep to warn you it is taking a reading and update the GPS location, 2) Keep internet connection alive (for remote access), 3) Keep internet off and save to memory card (for areas with no internet access).
