Issue: Ear speaker not working or producing sound.

Jumper Solution:

Tools needed:

• Soldering iron and solder
• Wire (preferably 0.1mm or 0.2mm)
• Jumper wire (small piece)
• Torx screwdriver (for disassembling)

Step-by-Step Instructions:

1. Disassemble the phone: Remove screws, battery, and SIM card tray. Gently pry open the phone’s casing.
2. Locate the ear speaker: Identify the ear speaker component on the PCB (Printed Circuit Board).
3. Check ear speaker connections:
   • Verify connections to the motherboard.
   • Ensure no corrosion or damage.
4. Create a jumper:
   • Cut a small piece of wire (about 1-2 cm).
   • Strip insulation from both ends.
   • Solder one end to the ear speaker’s positive terminal (usually marked as “SPK+” or “EAR+”).
   • Solder the other end to the motherboard’s ear speaker output (usually marked as “SPK_OUT” or “EAR_OUT”).
5. Verify the jumper:
   • Double-check soldering and ensure the jumper is secure.
   • Avoid short circuits.

Jumper Points:

• Ear speaker’s positive terminal (usually marked as “SPK+” or “EAR+”)
• Motherboard’s ear speaker output (usually marked as “SPK_OUT” or “EAR_OUT”)

Additional Tips:

• Use a multimeter to test ear speaker continuity before creating the jumper.
• Ensure the jumper wire is thin and doesn’t touch other components.
• If you’re not comfortable with soldering, consider seeking professional help.
