Samsung Galaxy Watch 4 is truly magnificent to use paired with any Android or iPhone smartphone. It does enable users to do a lot of things but it has a few issues as well. Turns out Bluetooth pairing issues or others related to Bluetooth on your device and the smartwatch 4 is fairly common as well. After a tonne of research, we at GetDroidTips have come across X ways to fix Galaxy Watch 4 Bluetooth Connectivity Issue on both LTE and Classic variants. Tag along if you are facing such an issue on your smartwatch too.

1. Restart Bluetooth on Phone and Watch

The scenario is simple. You tried connecting your Samsung Galaxy Watch 4 with your phone and it didn’t pair. Well, to be honest, a lot could go wrong here. 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.

• On your Samsung Galaxy Watch 4: Navigate to “Settings >> Connections >> Bluetooth”. Turn on the Bluetooth toggle, turn it OFF and turn it ON again.
• On your Android smartphone: Bring down the notification panel with two swipe-down gestures and tap on the “Bluetooth” quick tile a few times. Tap on the last time to turn it ON.
• On your iPhone: Here, you will have to go through Settings >> Bluetooth and turn it ON or you can tap on the Bluetooth option on the Control Center.
• This particular method will nudge Bluetooth prompting it to turn ON and connect to the recipient proactively.

2. Check for the device

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. Using power-saving or battery-saving mode can obstruct the working of Bluetooth as well.

You have already paired a watch with your phone and it used to work properly until one day, it stopped working anymore. Something with the Bluetooth pairing might have gone wrong as you aren’t able to pair with the watch again. The simple troubleshooting method you can use is to unpair and pair again.

• Firstly, go to “Settings >> Connections >> Bluetooth” on your smartphone or bring down the notification shade and long-press on the Bluetooth quick tile to launch it.
• Proceed to check the “Paired Devices” and find your watch.
• Tap on the “More Settings” or “Advanced Settings” denoted either by two/three vertical dots or a cogwheel against the device you want to tinker with.
• Finally, tap on “Unpair” and it is done.

Your smartphone and the smartwatch work on a system of OS, apps, and processes. Turns out some functions might be unavailable for a short duration due to XYZ reasons of which, system glitch or issue is one albeit it is a temporary issue.

• To clear the app cache, go to Settings >> Apps >> Galaxy Wearable. You can even long-press on the Galaxy Wearable app and tap on “App Info” to find the same page as above.
• Now, check out the Storage >> Cache and clear it.
