If your watch detects motion it'll wait for you to respond.
That said, so far many people have reported the Apple Watch 4 to be capable of identifying real falls from pretend ones. The watch can now automatically detect falls using the next-gen gyroscope and call emergency services. Apple studied falls through tests involving 2,500 participants, then used the data to create an algorithm that can identify what's actually a fall and what's not.
AppleWhat is fall detection on Apple Watch?
A user on Reddit discovered that Fall Detection is only turned on by default if you are above the age of 65. Many reported that they could not trigger a fall alert on goal, but it's not clear if all of them had the feature turned on.
The Apple Watch Series 4 is about as popular as expected, needing around a month to ship from the manufacturer's U.S. e-store if you order it today, but if you've already received an early copy, it might not be a good idea to start tearing it down and verify its repairability. It was found out that there is some margin of error as falls on surfaces like carpets or foam failed to start the fall detector. The Apple Watch Series 4 offers significantly better results if you fall on the floor.
The iPhone maker is positioning the Apple Watch Series 4 as your go-to fitness tracking device.
Apple revealed that it shot incredibly high-resolution video of fire, water, and vapor for its new Apple Watch backgrounds. Its speaker is also 50% louder than the Series 3.
Apple does state, however, that "Apple Watch can not detect all falls".
Amazingly, despite the number of components involved, Apple Watch Series 4 scores pretty well on iFixit's repairability scale: 6 out of 10.
