Strava

My phone was an old Wildfire- I spoke to Strava about it and they said it was beyond their capabilities to support the large number of older Android handsets out there as there were simply so many combinations of hardware and software.

That said the Wildfire was/is a very old phone, and it wasn't particularly pokey when new, so if you phone is of a more recent vintage you may simply have an issue similar to the one that T4 had.

Log a support ticket with Strava- they are pretty good at coming back with troubleshooting advice.

What's the handset, out of interest?

Samsung galaxy ace, so not that vintage. Thanks for the advice though
