Schmmuck, Jun 28, 2016 : One plus veteran here since the OPO days. I just upgraded from the one plus 2 to the one plus 3 and am shocked at how bad the GPS tracking is. This is my jogging route and as you can see from the OP3 tracking on the left vs the OP2 one on the right, the OP3 is terrible. The readings are also inaccurate due to the jerky tracking. The conditions and pace are the same too. Heck I'm even using the same arm band and headphones. I wonder if this is due to a faulty GPS chip or just a bug? Anyone else facing this issue on the OP3? I use runkeeper and Strava both and both have been very flakey.
