I bought an old Samsung Gear Fit (R-350) to replace it, which, in conjunction with the S5 smart phone, worked for more than five years. When I ated the smart on the S20FE, some of the bracelet functions stopped working (receiving / calling calls from the bracelet) due to software incompatibility. Therefore, I had to choose for a long time, but these watches had the functions I needed. After connecting and downloading ates, everything worked and + many additional goodies were activated. For its price (14500) is quite good.
