Loud Speaker Not Working Whatsapp, Sensor problem

Alright Muhammad Talha , here’s what’s happening and how you can fix it:

Issue Explained:

Your proximity sensor is likely malfunctioning or overly sensitive. It's used to turn off the screen when you bring the phone to your ear. If it’s always detecting something near it, it’ll:

Turn off the screen.

Force audio to the earpiece speaker instead of the loudspeaker.

This is why:

Voice notes and calls only play through the earpiece.

Display goes black and becomes unresponsive until audio ends.

Try These Fixes (Step-by-Step):

1. Clean the Sensor Area:

The sensor is near the front camera. Clean that area gently with a dry cloth.

Make sure there’s no screen protector or dust covering it.

2. Check Proximity Sensor via Settings:

Dial: *#558# or *#*#64663#*#* to enter Vivo’s hardware test menu.

Run the Proximity Sensor Test.

If it shows “0” constantly, the sensor thinks something is always near.

Should switch between “0” (near) and “1” (far) when you move your hand.

3. Calibrate the Sensor (if available):

In the same hardware test menu, look for Proximity Calibration.

Follow on-screen steps.

4. Disable Sensor for WhatsApp (Temporary Workaround):

Unfortunately, WhatsApp doesn’t allow changing proximity sensor settings directly, but you can:

Use a third-party app like “Sensor Disabler” or “Proximity Sensor Screen On Off” (from Play Store) to control it.

5. Update Your System & WhatsApp:

Go to Settings > System > Software Update.

Also update WhatsApp from the Play Store.

If Nothing Works:

Back up your data and do a factory reset.

Or take it to a technician. If you're at ZULQAR SOLUTIONS or have tools, open the device and check if the sensor cable is loosely connected.
