Does the LTE version work without a phone?

Yes. With a cellular plan it can take calls, send texts and stream music on its own. Setup and some features still need a paired phone.

Can I use it with a non-Samsung Android phone?

Yes, most tracking and notifications work. ECG and body composition analysis require a Samsung Galaxy phone.

It is rated 5ATM, so it handles pool swimming and showers. Skip it for diving or high-pressure water.

The 46mm has a larger 1.4-inch screen and a bigger battery in a heavier case. The 40mm suits smaller wrists better.

Yes. It tracks sleep stages and measures SpO2, and can run continuous heart rate monitoring.

The watch, a magnetic charging cable and quick-start documents. A charger brick is not included.
