But, you have to connect watch to wifi first, than check for update. If You dont connect it to wifi, it says it is up to date.Amazfit is alive today because of his community. The hardware is impressive. The phone App is decent, when it's work (I had quite often connection and sync issues, loss of activities and step counters for weeks). But here comes the firmware. Any new update create new problems. You mocking your customers with the quality of the firmware, GPS fixing took over 20 minutes, the path recorded looks like a drunk man way to his home, crashes and overall a lack of service availability. Lyndino, 18 hours agoMaybe you picked the wrong workout?I had the same problems. Outdoor activities crashed during the record, may caused by lost GPS signal. After that the watch screens senseless numbers and you have to abort the activity without saving. So in my opinion the watch is useless for tracking outdoor activities.Customer service also replied to wait for firmware update, which never has been released in more than 6 months, although they "know" about this problem!!After 2 watches has been replaced, I finally switched to Garmin.alyy8128, 21 hours agobeen using this almost a year.

Amazfit app was great about 2 years ago.Now Amazfit Stratos 3 (and other products?) have problems like using bad templates for sport tracking e.g. cross country skiing (and all ski activity) uses downhill template (another template does not exist).. Total downhill distance is not kind of distance you want to measure during cross country skiing. This problem is not patched for 4 months.been using this almost a year. Not sure is my unit got issue or not. The watch will crashed during workout. It been happen for months and the customer care only replied to wait for firmware update. Been updated once, but yet the issue still happening. Can't really rely on it. Disappointed. this watch is expensive, i can actually a buy a poco x3 nfc with it.
