Blu Studio Selfie – Disassembling procedure – How to replace the Microphone

Make sure your phone is powered off.
Turn the front of the phone away from you.
Run your fingers along the sides of the phone to identify where the case can be pulled apart.

Insert the flat end of your plastic opening into the crevice you found along the side of the phone.

Gently apply pressure until you feel the back case pop free of the phone.
Continue the previous two steps around the rest of the phone until the case is fully removed.

Identify the crevice at the bottom of the battery.

There should be enough space for you to fit your fingernail between the battery and the phone.
Gently lift the battery free of the phone.

Remove all the 4mm Phillips #000 screws from the midframe.

Insert the spudger between the midframe and the display assembly.

Gently pry up the midframe. The metal spudger is great when you need serious prying power, but the regular black nylon spudger or a plastic opening tool should be used whenever possible.

Where the battery rested before, you will find a small clip that holds down the midframe.

After the rest of the midframe is detached, from the phone place the flat end of the spudger beneath the clip.
Gently lift up on the clip until it comes free.
Remove the midframe from the phone.

Locate the microphone which has a small plastic protective covering.
Using a tweezers pull out the microphone  

Remove three 4mm Phillips #000 screws holding the motherboard in place.

Carefully lift the motherboard from the phone, exposing the microphone.

Desolder the microphone.
