How can I fix my phone's speaker?

although you havent specifically said whats the problem with your speaker, I have searched the web for some possible ways to fix the speaker problem on your Lenovo A6000 phone. Here are some steps you can try to fix it:

• Check the speaker assembly for possible damage or misalignment. Use a multimeter to check it, replace if already busted. If the speaker is okay, check and clean the speaker terminal contact pads. Corrosion might weaken and loosen the connection¹.
• Trace the speaker+ and speaker- connection to each certain component where it is connected. Check and replace the filter capacitor and resistor components¹.
• Watch this video tutorial on how to fix Lenovo A6000 ear speaker problem using jumper solution².
• Watch this video tutorial on how to fix Lenovo A6000 no sound problem using service mode³.
• If none of the above methods work, you may need to take your phone to a professional service center or contact Lenovo support for further assistance.

I hope this helps you solve your speaker problem. If you have any other questions, please feel free to ask me. 😊
