Opening the Realme C12

- Lift the plastic back with a suction cup and pick around the edges.
- Disconnect the rear fingerprint and antenna flex.

Disconnect the battery connector and ease out the adhesive pull-tabs (or apply isopropyl alcohol). The large 6000mAh cell needs even handling — never bend it. Fit and re-seal.
