While changing battery I have spotted signs of moisture, should I worry? The phone was not dropped on water. It has a broken back glass so I suppose that’s how moisture got inside. What should I do?
As long as there’s no corrosion on the board I’d leave it open to dry out for a bit. When you close it up sellotape the back glass top to bottom to seal it. Don’t take it anywhere like a bathroom if there’s moisture present. Also look into getting the back glass replaced.
