If your Fairphone 5 won't connect to your headphones, car, or speaker, it can be incredibly frustrating. Bluetooth issues are common on any Android phone, but the good news is they're often simple to resolve. I'd start with the basics and work through these steps, which are tailored for your Fairphone 5 running Android 14.
Check the Simple Things First
Before you try anything complicated, run through this quick checklist. It solves more problems than you might think.
Make sure both your Fairphone 5 and the device you're connecting to have enough battery. A low battery can cause unstable connections. Ensure Bluetooth is actually turned on by checking for the icon in your quick settings panel.
Keep the devices within about 30 feet of each other without major obstructions. Confirm the accessory is in pairing mode, which usually involves holding a button until a light flashes. Finally, test your Fairphone with a different Bluetooth device to see where the problem lies.
Toggle Bluetooth and Restart
The oldest trick in the book is often the best. Swipe down from the top of your screen to open the quick settings panel and tap the Bluetooth icon to turn it off. Wait about ten seconds, then tap it again to turn it back on.
If that doesn't work, give both devices a fresh start. For your Fairphone 5, press and hold the power button until the power menu appears, then tap restart. If the phone is unresponsive, you can force a restart by holding the power button for over 10 seconds. Power cycle the Bluetooth accessory as well, then try pairing again.
Forget and Re-Pair the Device
Sometimes the pairing information gets corrupted. Go into your phone's settings to remove the troublesome device and start fresh.
Open Settings and tap Connected devices. Tap Previously connected devices or the name of the paired device, then select Forget or the trash can icon. Put your accessory back into pairing mode and search for it on your Fairphone to create a new connection.
Clear the Bluetooth System Cache
Android stores temporary data for Bluetooth in a cache, and this data can sometimes become faulty. Clearing it is a safe, effective step that doesn't delete your personal data or paired devices.
Go to Settings > Apps > See all apps. Tap the three-dot menu in the top right and select Show system apps. Scroll down and find Bluetooth in the list, then tap on it.
Tap Storage & cache and then select Clear cache. Restart your Fairphone 5 and test the Bluetooth connection again. If problems persist, you can return to this menu and choose Clear storage or Clear data, but this will forget all your paired devices.
Check for Software Updates
Fairphone is committed to long-term support, and a software bug could be affecting your Bluetooth. Installing the latest update is a crucial fix.
Open Settings and go to System > System update. Your Fairphone 5 will check for any available updates. If one is there, download and install it. It's also worth checking if your Bluetooth headphones or speaker have a firmware update available through their own app.
Boot Into Safe Mode
If a recently downloaded app is causing a conflict, Safe Mode will tell you. This mode temporarily disables all third-party apps.
Press and hold the power button until the power menu appears; if that opens your voice assistant instead, press and hold the power button and Volume up together (power and Volume down on Samsung phones). On the screen, tap and hold the Power off option. You should see a prompt to reboot to Safe Mode. Tap it to confirm.
Once your Fairphone restarts with "Safe Mode" in the corner, try using Bluetooth. If it works perfectly here, a third-party app is the culprit. Restart normally and try uninstalling apps you installed around the time the problem began.
Reset Your Network Settings
This is a more thorough step that resets all wireless communications back to their default state. It will erase your saved Wi-Fi networks, Bluetooth pairings, and mobile data settings.
Go to Settings > System > Reset options. Tap Reset Wi-Fi, mobile & Bluetooth. You'll need to confirm your PIN or pattern, and then confirm the reset. After your phone reboots, you'll need to re-pair all your Bluetooth devices and reconnect to Wi-Fi.
Consider the Modular Hardware
One unique aspect of the Fairphone 5 is its user-replaceable parts. While rare, a loose connection could theoretically affect internal components.
If you're comfortable, you can power the phone off completely and remove the back case. Gently remove and then re-seat the battery, ensuring it clicks firmly into place. This action can sometimes clear a deeper hardware glitch. Reassemble the phone, power it on, and test Bluetooth again.
Address Car Bluetooth Specifically
Car systems can be particularly finicky. The most reliable method is a clean slate on both sides.
Go into your car's infotainment system settings and delete your Fairphone 5 from its memory. Then, on your phone, forget the car's Bluetooth system as described earlier. With both devices cleared, turn your car's ignition to the "on" position and make sure the stereo is set to Bluetooth discovery mode. Initiate the pairing process from your Fairphone's Bluetooth settings menu.
Perform a Factory Reset
This is your last resort before considering a hardware fault. A factory reset will erase everything on your phone, so you must back up any important photos, messages, and files first.
You can back up to your Google account or transfer files to a computer. Once backed up, go to Settings > System > Reset options > Erase all data (factory reset). Follow the prompts to complete the reset. After setup, test Bluetooth before restoring your apps and data, to see if a clean install of Android fixes it.
