How to breakdown:

Tools Used: screw driver, tweezers, x-acto knife, hair dryer, phillips head, my nails 😛

Techniques: unscrewing, heating up, and prying, lots of prying

Step 1:Remove back casing and detach logic board

Step 2: Open up the front half of the phone, starting with the sliding mechanism side, and remove LCD panel and front keyboard circuit from front casing.

Step 3: Detach LCD connector and remove EMI shield and speaker module with camera/audio jack from logic board.

Two design elements I found interesting:

1. The slider, the sliding mechanism, and the holes in parts of the casing are positioned in such a way to accommodate the LCD connection. Prior to taking it apart, I had no idea how that worked, so it was exciting to discover during the teardown!
2. I like the difference in texture between the back plate covering the battery and the rest of the phone. While the rest of the purple plastic in the case is smooth, the back has a more raised texture. I think this was done for better grip when the user is holding the phone and to distinguish the part that can be removed to access the battery.
