When Redmi Watch 4 is exercising indoors, the number of steps is rising even if I don't exercise?

The distance between indoor walking and outdoor walking of the watch is calculated in different ways. The outdoor is calculated according to GPS positioning and indoor is calculated according to the sensor hardware of the product. If you open the outdoor walking exercise mode in an indoor environment, due to the weak indoor GPS signals, the signal drift of the analog GPS amplifier signals and the phone in the indoor environment GPS signals are weak and therefore the GPS positioning of the sent back and forth jumping back. Please choose the corresponding exercise mode according to the correct environment. For outdoor exercise, you can choose outdoor cycling, outdoor running and other exercises; for indoor exercise, please choose indoor running, indoor swimming and other exercises.
