spark cardio not synching with phone lg4
So I've got myself a Tom Tom Spark Cardio. Previously i had a Garmin Forerunner 220, which was great by the way. However, i wanted a Spark because firstly it has a built in heart rate monitor. Secondly, i like the idea of the race function. Two weeks in, syncing my watch to LG 4 is a nightmare, constantly unpairing just to upload runs. The second glitch was yesterday, decided to go for a race. Started watch, gps kicked in, go go go so i thought! A km or so down, glanced at watch, watch indicated i hadn't even moved, distance wasn't budging. So i started again, exactly the same thing happened, at this point i gave up. I just ran normal route. Got home not feeling invigorated really, i was annoyed. Runs apparently uploaded, one run said i had been active for 6 mins, stood still for 23! I'm totally confused with this watch, even when watch was working kinda, pace wasnt accurate, compared to my garmin i was running a lot slower, and i was flogging it. Another annoying thing, cannot factory reset watch, i dont have a PC. I have tried to reach out to tom tom via instagram and facebook, haven't had any response so far. Please can anyone help me put the spark in this spark???
