Hi
@C1a1r Actually I think the rice trick is a bit of myth, not really good practice as it can cause damage ( even if some have been fortunate)
Best to keep it in clean water for a few minutes to remove salt and substances and then leave in the open air to dry.
If it can not be revived an idea to use a local recycling service.

I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.
