After the first time (with my Huawei P8Lite) when everything went well, the app doesn't seem to connect to the internal gps, always looking for satellites...
Might be something with the GPS firmware. Try following: 1) Reboot the phone. Sometimes the GPS firmware can get stuck on the phone. 2) Make sure the phone has data connection, by accessing any site at web. The data connection is not 100% required, but it helps the phone lock to satellites faster. 3) Go outside, never run tests inside as it won't lock to satellites 4) Start session. You should get satellites locked within 5 minutes.

Let me know if it works.
