I have at long last tried to move into the Strava age, using the app on my phone, and set the recording mode to GPS only (rather than GPS + data to save on battery + my data allowance). Over several days, I have not managed to get a whole ride recorded. I either get the start or end missing, and sometimes gaps in the middle that are replaced by a straight line and daft maximum speeds (148km/h!). Additionally, today I got segments that ran parallel to but not on the roads, linked then by straight lines back to the real route. In this example the western end is a straight line, missing about 6 miles, and it stops a couple of miles short of home. My phone is a Huawei P8, and I gather GPS problems are not unknown on this make (but not limited to it either). I've tried various on-line tips to change phone settings but I've still not had 100% success. Are other people managing OK using phones to record their rides on Strava? Any ideas?
