I'm really hacked off with my Galaxy so far.  It looks cool and the notifications are good but its operation regarding activity tracking is so poor.  Same issues as already mentioned re heart monitoring. No records during any kind of wrist movement; extra tight straps improve but don't solve it; adding BPMs to the max when moving my arm (that or I'm about to have a cardiac arrest!) and having to reset it to get it working again. I found wearing a sweatband over it during squash games helps but that should not be necessary.  I'm also finding the Bluetooth connection to my Nokia 6.1 to be temperamental, constantly having to be reconnected,  and the app seems to be poorly designed with extra teeny weeny text hard to read. So either the watch has a poor HRM and cruddy app design or I've got a dodgy ticker and failing eyesight......Hmmm My old £100 fit bit does a better job of the activity monitoring so I might go back to that to make me feel young again!  The Samsung does look cool but I'm seriously thinking of asking for a refund  - not fit for purpose!      ...
