At one point you notice that the sound on your Android smartphone is louder does not play through speaker. Music, calls, notifications - everything works only through headphones, wired or Bluetooth. This can be unexpected and annoying, especially if you don't carry your headphones with you all the time.
Why does this happen? Below we examine the main reasons, how to get sound back on speaker, and what to do if the problem does not go away.
🔍 Main reasons: why sound only comes through headphones
📌 1. The phone “thinks” that the headphones are connected
Sometimes the Android system mistakenly recognizes the presence of a headset, even if it has been disconnected for a long time. This may be due to a software glitch or physical contamination of the connector.
📌 2. Audio jack (3.5 mm) malfunction
On some models, when the contacts wear out or become oxidized, the connector “sticks” and the system thinks that the headphones are still inserted.
📌 3. Problem with Bluetooth
The smartphone automatically connects to a known Bluetooth device (headphones, speaker) and continues to transmit sound there, even if you don’t want it to.
📌 4. Firmware or system settings failure
After updates, resets, or installation of audio-related apps, your phone may behave abnormally and redirect audio.
📌 5. Damaged main speaker
If your smartphone does not fall or come into contact with moisture, but the speaker is silent, it may simply be broken. This is a hardware malfunction.
📌 6. Protected mode in headphones/TTY mode
Some settings are available for users with hearing impairments, such as TTY mode or mono audio. These may affect the audio behavior.
✅ How to fix: step by step guide
🧹 1. Clean the audio jack
Often the problem lies in dirt, dust or lint, which get into the 3.5 mm jack. This creates a short circuit, and the phone “thinks” that the headphones are connected.
🔧 What to do:
-
Turn off your phone
-
Clean the connector carefully. with a toothpick or a needle, without pressing too hard
-
Use compressed air or a vacuum cleaner with a fine nozzle.
⚠️ Never pour alcohol inside - it can damage the microcircuits.
🔄 2. Restart your device
Many problems can be solved with a simple reboot, especially if the cause is a software glitch.
-
Hold down the power button
-
Select “Restart” or “Shutdown”
-
Wait 20 seconds and turn it on again
🛠 3. Check the Bluetooth connection
If the sound comes through wireless headphones, turn them off:
-
Go to Settings → Bluetooth
-
Turn off all active devices
-
Or turn off Bluetooth completely
📌 Check if the sound behavior has changed.
⚙️ 4. Reset sound settings
-
Go to Settings → Sound
-
Check balance, volume, ringtones
-
Click “Reset Sound Settings”, if there is such an option
Sometimes resetting all settings helps:
Settings → System → Reset → Reset settings (without deleting data)
📱 5. Use the Audio Switch app
Third party applications like SoundAbout or Audio Router allow you to manually route sound from headphones to the speaker if the standard settings do not help.
🧪 6. Check the speaker via the engineering menu
Some smartphones (especially Xiaomi, Samsung, Realme) have test menu, which allows you to check the speaker's operation.
-
Call the number #0# (or other code - depends on the model)
-
Test the main and earpiece speaker
-
If the speaker is silent, it may be faulty.
🛠 7. Contact the service center
If none of the methods helped, perhaps:
-
Damaged audio controller on the board
-
It doesn't work multimedia speaker
-
Moisture penetrated inside and caused oxidation of contacts
The service will be able to accurately diagnose the problem and replace the speaker or connector if necessary.
❗️What not to do
🚫 Do not pour WD-40, alcohol or oil into the connectors
🚫 Do not press hard on the screen or case in the hopes of “pushing out” the sound
🚫 Don't install dubious "sound repair" apps
These actions may permanently damage the device.
🧾 Conclusion
If the sound on your Android smartphone works only through headphones, the reason may be either a small software glitch, and in hardware failure. Start with simple steps - cleaning, rebooting, checking Bluetooth. If this does not help, do not delay a visit to the service: in the early stages, repairs are always cheaper 💸
Careful attention to the device and regular cleaning will help to avoid such problems in the future. And if something goes wrong, know that there is almost always a solution! 👨🔧📱
