When doing indoor exercise on the Xiaomi Watch S3, does the step count increase even if you are not exercising?

The distance calculation method of the watch for indoor walking and outdoor walking is different. Outdoor calculation is based on GPS positioning, and indoor calculation is based on the product's sensor hardware. If the outdoor walking mode is turned on in an indoor environment, due to the weak indoor GPS signal, the simulation The signal drift of the GPS amplifier signal and the weak GPS signal of the mobile phone in the indoor environment, so the GPS positioning issued bounces back and forth, resulting in the problem of increasing the number of steps without exercising. Please choose the corresponding exercise mode according to the correct environment. You can choose it for outdoor exercise. For outdoor cycling, outdoor running and other sports, please choose indoor running, indoor swimming and other sports for indoor sports.
