Why Speaker Has No Sound After Replacing the Charging Port?

If you've recently replaced your phone's charging port (also known as the tail connector or USB flex cable) and suddenly realize that the speaker isn't working, don't panic. The problem can be caused by several reasons, most of which can be fixed. Here are the possible causes and solutions:

1. Headphone Detection Error

Some smartphones have a detection mechanism that routes audio to the headphone jack when plugged in. If the system incorrectly assumes that the headphones are still connected (even if they are not), the speaker may stay silent.

Fix: Try inserting and removing the headphones several times or restarting the phone.

2. Loose or Improperly Installed Charging Port

If the new charging port is not installed properly during the installation process, it may not be able to establish a proper connection with the motherboard, thus affecting the audio output.

Fix: Open the device again and make sure the flex cable is firmly connected. Check for any bent or misaligned pins.

3. Damaged or Disconnected Speaker

During the repair process, the speaker's flex cable might have been accidentally loosened or damaged. Additionally, if the speaker was already aging, the repair may render it completely useless.

Fix: Check the speaker connection and test with another speaker if possible.

4. Software or Firmware Glitch

Sometimes a system update or software error can interfere with audio output after a hardware change.

Fix: Try resetting the settings, performing a factory reset (backup your data first), or flashing an older firmware version.
