OppoA72 fell into the water and has been used for more than three months now. The battery is a little hot.

Don't press any keys, and don't turn off your phone. Just open the back of the phone and take out the battery.

Step 2 remove water

Don't blow dry with a hair dryer or bake on the stove, because the external heat will damage the precise electronic components inside the mobile phone. Don't try to turn it on, it's not right, even if the phone itself is not damaged, once it is turned on, it may cause the motherboard to burn out or the motherboard to short circuit!

The correct way is to wipe it quickly with a clean towel to ensure that water will not flow into sockets such as charging ports and earphone holes. If you find water flowing into the phone along the interface or gap, you should carefully blow it out with compressed air, and never blow it deeper and deeper.

3, drying treatment

You can prepare some desiccant or drying box, collect the desiccant, and seal the mobile phone soaked in water with desiccant. Or put the mobile phone under a micro-heat source such as a desk lamp and spotlight to let the water disperse slowly, and see if the functions such as ringtone are normal.

If you still can't suggest going to the outlet to have the engineer check and repair.
