You're staring at your Nothing Phone (3), watching the Wi-Fi icon spin endlessly or just refuse to connect. It's a frustrating roadblock, especially on a new device. The good news is that on Nothing OS 3.0, this is almost always a software hiccup you can fix yourself in a few minutes.
Toggle Wi-Fi and Restart Your Phone
Start with the simplest fix. Swipe down from the top of your screen to open the Quick Settings panel. Tap the Wi-Fi icon to turn it off, wait a solid five seconds, then tap it again to turn it back on. This forces your phone to drop the connection and re-scan for networks, which often clears up a temporary glitch.
If that doesn't work, give your Phone (3) a full restart. Press and hold the power button until the power menu appears, then tap "Restart." A reboot clears out any temporary system bugs that might be interfering with the wireless hardware.
Use Airplane Mode to Reset Radios
This is a more thorough version of toggling Wi-Fi. When you enable airplane mode, it shuts down all wireless communication—Wi-Fi, cellular, and Bluetooth. Turning it back on forces every radio to reinitialize from scratch.
Swipe down for Quick Settings and tap the airplane icon. Leave it enabled for about 15 seconds, then tap it again to disable it. Watch to see if your Wi-Fi reconnects automatically. I've seen this resolve stubborn connection issues on many Android phones.
Forget the Network and Re-enter Your Password
Your phone might be holding onto outdated or corrupted information for your home network. To clear it, go to Settings > Network & Internet > Wi-Fi. Tap on the name of the network you're trying to join, then select Forget.
Now, tap on the network again from the list and carefully re-enter the password. This is crucial if you've recently changed your Wi-Fi password or gotten a new router. Your Phone (3) won't be able to connect if it's using the old credentials.
Check for Router or Interference Issues
Before you dig deeper into phone settings, make sure the problem isn't with your Wi-Fi source. Unplug your router from power, wait a full 60 seconds, and plug it back in. This simple reboot fixes a huge number of home network problems.
Also, consider potential interference. Bluetooth devices and even some wireless peripherals operate on the 2.4GHz band, which can clash with Wi-Fi. Try turning off Bluetooth from your Quick Settings to see if your Wi-Fi connection stabilizes.
Disable Adaptive Connectivity and Battery Saver
Nothing OS includes features designed to optimize battery and data usage, but they can sometimes be too aggressive. First, check Adaptive Connectivity. Go to Settings > Network & Internet > Adaptive Connectivity and toggle it off. This feature can switch you to mobile data if it deems Wi-Fi too slow, which might prevent a stable connection.
Next, look at Battery Saver. When active, it can severely limit background network activity. Go to Settings > Battery and make sure Battery Saver is turned off. If your connection returns immediately, you've found the culprit.
Verify Your Date, Time, and Software
An incorrect date or time can break Wi-Fi authentication because security certificates rely on accurate timestamps. Go to Settings > System > Date & time and ensure "Set time automatically" is enabled.
Then, check for a system update. Nothing regularly releases updates that fix bugs and improve stability. Navigate to Settings > System > System update and download any available updates. An update in 2025 or 2026 could very well include a patch for your exact Wi-Fi issue.
Reset Your Phone's Network Settings
If you're still stuck, resetting network settings is a powerful step. This will erase all saved Wi-Fi networks, Bluetooth pairings, and mobile network preferences, returning them to factory defaults.
To do this, go to Settings > System > Reset options. Tap on Reset Wi-Fi, mobile & Bluetooth. Confirm the action. After your phone reboots, you'll need to reconnect to your Wi-Fi and re-pair any Bluetooth devices, but it often resolves deep-seated connection problems.
Boot Into Safe Mode to Check for App Conflicts
A third-party app you installed could be causing the conflict. Apps like VPNs, ad blockers, or certain "cleaner" utilities are common suspects. Booting into Safe Mode temporarily disables all downloaded apps.
To enter Safe Mode on the Nothing Phone (3), press and hold the power button until the power menu appears. Then, tap and hold the "Power off" option on your screen. You should see a prompt to reboot into Safe Mode. Tap "OK." If your Wi-Fi works perfectly in Safe Mode, you'll know a downloaded app is to blame. You can then start uninstalling recent apps one by one to find the offender.
Consider Your Phone's Physical Environment
While the Glyph Interface on the Nothing Phone (3) is iconic, your case might be part of the problem. A case with a lot of metal or very thick, dense materials can attenuate Wi-Fi signals. Try removing your case temporarily to see if your connection strength improves.
Also, remember that Wi-Fi signals can be blocked by walls and large appliances. If you're having issues in one specific room, it might simply be a matter of distance or physical obstruction from your router.
Perform a Factory Reset
This is your last resort. A factory reset will wipe your Phone (3) back to its original out-of-the-box software state, eliminating any software corruption. You must back up all your important data first—photos, messages, and app logins—as this process erases everything.
To proceed, go to Settings > System > Reset options > Erase all data (factory reset). Follow the on-screen instructions. Only use this step if every other fix on this list has failed. If Wi-Fi still doesn't function after a factory reset, the issue may be hardware-related.
