This is the Samsung Galaxy Centura, a low-end smartphone made for the Tracfone/Straight Talk networks.

Remove the battery, and then remove the 7 Phillips screws surrounding the outer casing.

Pop the 4 clips on both the left and right side of the phone. The outer casing should come right off by pulling.

This antenna can be removed with a spudger or screwdriver.

This is the speaker assembly (with more antennas!)

Disconnect the two flex cables with a spudger or plastic opening tool.

Now the display assembly is free.

Remove the 3 Phillips screws on the back of the motherboard to remove the EMI shielding.

Congrats! You've torn down the Samsung Galaxy Centura.
