The problem: sometimes when GPS signal is lost, it uses location from cell or WiFi, even when option 'use GPS only' is turned on.

First location after GPS restored (44.823411,xx.xx7664) is incorrect (about 500 meters from actual location) and it is written to the track.
May it be bug in OS, that supplies location from Wifi but marks it as if it is recevied from GPS ?
I will try turning off Google Location Accuracy as suggested in Jun 30 message to see if it helps.
