* Problems occur when the phone incorrectly detects a headset. * Where the "problem" lies: * The issue is often with the physical headphone jack itself (if your phone has one), or with glitches in the phones software. * Physical issues: Lint, dust, or moisture can get into the jack, causing it to think a headset is plugged in. * Software issues: Sometimes, software glitches can cause the phone to get stuck in headset mode. * Troubleshooting, not a setting: * Therefore, you don't "find" a headset mode setting to turn off. Instead, you troubleshoot the problem. * This troubleshooting can include: * Cleaning the headphone jack. * Restarting your phone. * Checking for software updates. * Trying to plug and unplug headphones multiple times. * In some cases, 3rd party apps can help to overide the audio output. * As a last resort, a factory reset.
