There are very few applications in the Play Store (there is no way to watch YouTube, no applications for the w3bsit3-dns. Com forum, no convenient viewer for stocks of companies and currencies, news, etc.), the almost complete absence of pre-installed dials with seconds.
Strength training is a real problem. Neither set up normal approaches (only the same number of repetitions in all approaches), nor manually drive in unmeasured indicators (such as the number of push-ups or pull-ups, the number of which cannot be tracked from the clock), and even with manual recording (manual, by the way, is more convenient for me) - it is impossible to turn on next approach. Although Samsung has a wonderful idea: there is auto-tracking of repetitions (where hands participate), a timer for a break between sets (sorry, not customizable). The exercises themselves are also not enough, even if there are a lot of them, but, for example, there is no very popular exercise - lifting the barbell for biceps (only dumbbells), there are no ordinary slopes (this is more of a warm-up exercise, but still .). The potential is visible, there are interesting ideas, but not fully implemented.
The autonomy of the watch is not so hot - the estimated time is from one working day, up to three days, depending on the frequency of use and the number of trimmed monitorings. However, it's more a matter of physics - well, such a small device is not capable of containing a capacious battery. Either it will be larger, or you will have to sacrifice the quality of some smart functions, for example, GPS data is not ated so often.
