For starters, try toggling Bluetooth on both your device and the smartwatch. This should fix any redundant issue where the system was unable to establish Bluetooth pairing due to XYZ reasons.

Your Samsung Galaxy Watch 4 has Bluetooth v5.0 and most of the smartphones today support it as well. This means you have a theoretical limit of 800 feet but that’s out of the picture as it is theoretical. Usually, the maximum distance between two Bluetooth devices is about 32 feet but it is the same to assume that it is between 20 to 30 feet. The Bluetooth reception decreases proportionally to the increase in the distance between the two devices. Take walls, ceilings, floor, and other obstructions in mind as they tend to decrease the intensity of the signal considerably.

If you were trying to connect your phone to the watch and it didn’t pair, check the distance between the two. Also, if you are moving concerning the recipient, the reception could go off for a toss as well.

3. Check for Low Battery Level

Just like Wi-Fi or GPS, Bluetooth on Galaxy Watch 4 or any device consumes power and thus, a low battery can cause the functionality to tumble. The South Korean giant Samsung recommends 25 percent of battery on both the watch and the phone to ensure seamless pairing and synching without a glitch. It is possible that at least one of your devices had a low battery which prevented the devices from pairing. This is one of the basic Galaxy Watch 4 Bluetooth Connectivity Issues right there.
