Huawei P9 Lite Battery Charge Indicator: Constant Blue Light After 100% Charge & Water Damage

Please help. On the huawei p9 lite, the battery charging indicator or any notifications are constantly blue. Of course, when loading, it changes the colors it should. But after being 100% charged, it glows blue. I will add that it was flooded. I gave it under the guarantee, but I was not recognized for obvious reason. I would also like to add that it was lying around for two weeks. I recently launched it and it works fine, of course, apart from the 'diode' indicator. What could that mean ????

It may mean that it was flooded and shorted.

Corrosion will eat it from the inside if it is not dried and cleaned as soon as possible.

Take the phone to some service center where they will take care of it properly before corrosion will do even more damage. You don't have the warranty anyway, and you won't do anything yourself.
