Upgraded from my S3 Frontier. The screen on the watch is stupendous - ultra clear in any light. I'm thoroughly amazed with how tough the glass is - there have been several incidents where I panicked thinking I just destroyed my new watch, but found an pristine, unscratched surface. The battery life is awesome, easily making it through the day.
Had this for about couple of weeks and it has been amazing. I had the frontier S3 and it still worked like a gem but sadly my S24+ phone couldn't connect to it and so I traded it in for a great deal and got excellent upgrade.
I updated from a Galaxy 5 and love how much thinner this watch is and also seems more accurate on blood oxygen levels. Also a serious note this watch alerted me that I had a AFIB. Went to my cardiologist and he made me wear a monitor for a week and yes confirmed AFIB. My 5 never alerted but again maybe wasn't happening then. Bad thing is the battery doesn't last as long as the 5 but thats not a deal breaker.
