How to use it
- Locate the bottom-edge speaker slots beside the USB-C port.
- Remove the case, raise media volume to maximum.

Good to know
- OPPO's water resistance ranges from splash-resistant mid-rangers to rated flagships โ the Reno and A series differ model by model, so never assume immersion is safe.
- Some ColorOS versions bundle a speaker-cleaning sound in the Phone Manager/tools area; if yours lacks it, this browser version covers you.
- After any water exposure, OPPO's standard care pattern applies: dry exterior, no charging while damp, moving air.
