The previous Samsung I had. I bought in 2016. I had no issues with it at all. In 2021 I gave my old phone up for an upgrade to S21 Ultra and now in 2024 I'm already having issues. I must say it is very disappointing. I feel they are causing these system errors on purpose so that we keep upgrading phones. The moisture detected error simply won't go away. There is no moisture or debris in my charging port. I have tried everything I can. Nothing has work. The phone only charges when it is completely out of power. I dread the day it stops charging all together.
