    Hello, the oxidation, the rust, the microchips or other parts which get lost connections on PCB. It will be hard to bring the phone back to life. After the phone ducked into the water, you have to disconnect a battery and bring the phone to a qualified specialist. Or skip the first part and go to repair service.

You should mention proper name of the phone while making any video. It could give you likes but it is of no use by giving a false name because the device is not just Redmi 4. Stupid

        Oh, man! You are both right and mistaken. This is Redmi 4 for the Chinese market also known as Xiaomi Redmi 4 Standard. The Prime has Flash on the left side from the camera lens. But thanks anyway, you're a good man.

    Hi, you don't need to buy anything instead of the camera. This camera connects to the PCB with FFC (Flexible flat cable). It can be glued with double-sided adhesive tape.
