fenix 5 serial number list and connectivity issues

peteholloway
over 8 years ago
EDIT: Just an update, it's becoming clear that we need more serial number info than just the first 3 digits, as these number only indicate the model, not the batch. Please provide additional serial number info.

536 = f5 slate with black band
537 = f5 silver with blue band
538 = f5 slate with yellow band
53A = f5 Sapphire
53B = f5 Sapphire slate grey with metal band53C = f5 Sapphire slate grey with metal band
568 = f5S
56D = f5S

Let's collect as much info as we can to see if connectivity issues are related to specific models, serial number batches or paired phones. Here's a start from the info on the beta thread:

    S/N: 536117611
    Bought: May 4, 2018
    FW: 8.00
    GPS: Pretty close to readings I got with a Vivoactive 3 & FitBit Ionic. But, I run in the country. No buildings.
    BT issues: surprisingly 'none'! Vivocative HR was a bitch. V3 was better. Fenix is good -- SO FAR (but I have only had it 10 days).
