Information to get the most out of the Watch4
I am learning a lot about this watch. One thing I can pass onto others, if you want an inactivity alert like other smartwatches (gives you alerts when you have been inactive for a certain amount of time), you have to get the "Wear Stand Up Alert" app. Unfortunately, it is compatible only with the Google Fit app. (Since this is now a Google Wear OS, Google Fit and Samsung Health are both compatible on this watch). This means for all those who still want Samsung Health, you must also run Google Fit so that the inactivity minder alert will work. Also, don't worry about the mention that the inactivity app works best with the bubble software. I got everything working fine without it and the bubble stuff is too complicated if all you want to do is get an inactivity alert working. I am tied to use both health tracking apps because I need Samssung Health since I swim and Google Fit doesn't track swimming, You can manually take the Samsung Health swim tracking information and enter it into Google Fit, but this can only be done on the phone, not the watch. I also prefer Samsung Health over Google Fit for other reasons such as auto detecting workouts. Google Fit doesn't trigger fast enough for that IMHO. Concurrently using both methods does drain the battery much faster. In addition, I use the sleep tracking. I am talking lots of battery demand here. Luckily, I am able to get a full day of battery life using both tracking methods only because I am willing to run the watch in grayscale almost all the time. I find I only need color when I am trying to find an app whose icon is still unfamiliar to me till I see colors. Using the watch settings I set the double-finger triple-tap option to grayscale. Without the firmware update, it never triple taps from grayscale back to color. The firmware update fixes this. Also, I can't use Always-On due to trying to minimize battery drain which I can also live without. I get close to a full day of battery life because of these sacrifices. Even though Always-on is off, turning your watch so that it faces you should automatically wake up the watch. Yeah, don't count on it being reliable. In some cases, this is annoying when I need to use my other hand to tap the watchface to turn on the display. Sometimes, like when I am currently swimming, I just want to glance at the watch, and it doesn't turn on. So having to skip a stroke to turn it on is a pain. Hopefully, Samsung is listening. Please fix this! Samsung, hey, how about for us smaller watch people giving us better battery life? I would LOVE to have a battery that lasts more than a day! I did have a watchface on the Watch3 that I loved because of all the fitness and bio information right on the watchface. Unfortunately, this watchface is incompatible with the Watch4 and the developer told me it is due to going from Titan to Wear OS and it will be some time before he can support his watch faces on Wear OS. Sigh. Lastly, and this should have me knocking the rating down to 3 stars, I am not because to me, this is really about the watch itself. However, the watchband broke already after wearing it only 2 weeks. Since it is still under warrenty, I suspect that Samsung will replace it without blinking an eye. It's just a pain to have to wait for the replacement as I can't wear the watch swimming till one comes in. Also, I prefer a watchband that can still breath whether I am working out in the pool or outside. Staying damp under the watchband after a workout is not comfortable to me. So, that's it. Hope this helps someone out there!
Please make a feature to rotate the screen.
I like to primarily wear mine on the underside of my right wrist as its more comfortable for wear and for toggling. But the screen stays sideways that way. The screen rotates freely when you are holding it while it is on the charger, but not when it is on your wrist. An option to freely rotate or to have it face up when its under your right or left wrist would make this perfect. Side note: the design could be more streamlined.
