I use Locus Pro since many years. One of the most used features is the Track Recording, which always worked without problems. Since a couple of weeks the recording is interrupting. That means the recording isn't performed continously any more, but steps in a kind of stand-by mode. If I reactivate my smartphone after a while of recording with my fingerprint, Locus has to find the lost GPS position and draws a direct line from the last known position.
By the way: Previously, it was never a problem to lock the smartphone during track recording.
What did change since the time, when everything worked well?
I upgraded to Locus 3.23 AND to Android 7.1. This was more or less within the same time frame. So, I can't say if one or the other change was relevant for the new problem. Obviously I didn't get any more the dialog concerning the system/battery optimization when I started Locus Pro. With Locus GIS this dialog still appears (see attachment).
I tried out any settings for Locus and Android, but nothing could solve this problem, which is very annoying, because I can't use this feature any more.
