These steps help identify and resolve the underlying cause. After completing each step, test to see if the issue is fixed. If not, continue to the next step.
Does the device you're pairing with support the same Bluetooth protocols as your Apple iPhone 4s?
Refer to the Bluetooth device's user manual for compatibility.
Your Apple iPhone 4s is compatible with Bluetooth v4.0 with A2DP, AVRCP, HFP, HID, MAP, PAN, and PBAP.
If the manual doesn't list any of these protocols, your Apple iPhone 4s is unable to connect to that Bluetooth device.
Bluetooth may be turned off on either the Apple iPhone 4s or the other Bluetooth device. Be sure Bluetooth is enabled on both devices.
Is the Bluetooth device in range?
The Bluetooth communication range for most devices, including your Apple iPhone 4s, is about 30 feet. Be sure your devices are in range.
A soft reset deletes any temporary files that may be causing the issue.
Removing the pairing, restarting your Apple iPhone 4s, and then re-pairing the Bluetooth device refreshes and updates your connection.
Note: To optimize device performance, be sure your Apple iPhone 4s is running the most recent device software. Check for software updates.
