Hi @
edraalamsyahCan you try these troubleshooting steps?
1. Use a different pair of headphones/headset to see if the audio jack is working. Or Use the same with a different phone.
2.Run SMMI Test to check if there is any hardware issue
How to Enter SMMI_TEST (test hardware)
Go to Calculator=>type " .12345+= "
you will be entered to SMMI_TEST
If a hardware issue is found, please visit the service center.
