A few days ago I've started testing your tracking system, but I think I'm not using it very well. I'm testing with two smartphones, both Samsung (note 3 and note 8).
I'm the note 3 I have the wia tag app, on note 8 i have the GPS TRACE TAG app.
Yesterday they were working not so good but they were working, i think, but when there was a stop for a certain period of time , the wia tag just didn't work anymore. Today I wake up and start driving for a while and they are not working.
And on my note 8 i have gps-trace app and i also pure puffin browser to use GPS TRACE platform site
