Feeling like a numbnut here
There aren't many controls in the Traccar client. I don't see a way to view the logs.
I went to the file manager in Android and looked for anything with today's date, and there were only two files which weren't a log.
So, where are the logs for the Traccar client kept?
Every Android device comes with a standard system logging, but I'm not actually sure it would help you.
So, I changed to the Demo Server 1 from Demo Server 2, and interestingly enough, a lot of state updates started appearing.
I set it up exactly in the server as I did the client. In the client I only removed the "2" Server URL.
What do you know! Server 2 seems to have a problem in Canada!
Demo servers are generally not very reliable. They are almost always overloaded.
Yes, your cell phone. The date you see on the main screen is not necessarily the same thing GPS modules gives the app.
Can't check the logs, so if you want to investigate it deeper, you should debug it on the device side.
