  1. I need to update manually the DT28 firmware. Where do I find the firmware and the step by step to update it?

  2. I can confirm that the No.1 S10 watch is a very poor performer indeed. The display, even on maximum brighness, is almost completely invisible when outdoors, even on a cloudy day. Given that most fitness activity occurs outdoors, this completely eliminates any point in wearing this watch. Furthermore the GPS function and the compass functions flat out do not work at all – they are simply incapable of sensing a satellite, or true north – even in a wide open areas. The blood pressure function gives the impression it is taking a genuine reading, but the results are utterly unrelated to the wearer’s actual blood pressure (as measured by decend blood pressure cuff). Even worse, it gives an apparently normal and healthy reading even when no-one is actually waering the watch!
    And of course the application does not even work properly on my Samsung Galaxy S9
