1. Turn Off Your Device
First and foremost, you will need to make sure that your Galaxy A55 is powered off. Otherwise, there’s a pretty big chance that the device will undergo a short circuit, damaging it heavily, with little to no chance of restoration.
2. Shake Out the Water
To do that, hold your Galaxy A55 phone speaker-side down and shake it gently. It’s very important not to overdo it. Otherwise, you might accidentally push all that water deeper inside the device.
