Guidance along route - sometimes no alerts for waypoints with Samsung S7
I use "guidance along routes" together with alerts/notifications on navigation-waypoints and screen on/off during biking. It's my most battery-efficient way of bike navigation. I create routes with BRouter with navigation instructions or I add navigation-waypoints manually on existing tracks.
I use guidance with screen on/off and TTS notifications on navigation-waypoints for several months with my LG G2 (Android 5.0) without any problem. Now I use a Samsung S7 (Android 7.0) and on 10-20% of the navigation-waypoints I get no notification and the screen remains off.
On the LG G2 and on the Samsung S7 I use Locus Pro 3.24.3 together with exactly the same track and same settings.
In both cases Locus switches the guidance from a waypoint to the next waypoint according to the setting "Set next trackpoint" (in my case 100m) - but sometimes I get no notification with the Samsung S7.
Is the Samsung S7 too fast for Locus? Is it a problem of Locus? Is it a problem with the Samsung S7?
