I just bought a new Enduro 3, and when I connect and disconnect the cable to/from my laptop for simple charging and synchronizing with garmin express, the sunlight percentage at the bottom of the main watch face is lagging (e.g., it usually changes immediately to 100, 102, 101, and then changes to 30,40 when there is less sunlight, but no matter how bright it is, it stays at a certain value for a while, such as 30 or 100, and then changes back when I touch or press a button. Even then, the value changes once or twice and then the problem repeats again. Is this normal? (I went into the solar widget and the cumulative lux part is increasing by 0.1-0.2K, so apparently there is no problem with solar charging). I don't think it's a cold issue because it's the same even if I try it indoors with a stand-like light. Also, after 2 hours, the lag issue gradually resolves.
I asked Garmin Korea and they said that it might be a lag issue during the data integration process after synchronization, but does any Enduro 3 users or users of other Garmin solar models have similar experiences ? or does this display error feature just on my watch ?
Also, I wonder if it is related to overcharging.. because I overcharged my Enduro3 one time.
