S9 plus charging problem

[Shauryam]

I have a Galaxy S9 Plus I am using the original charging cable cable on one side of the cable the phone fast charges but on the other side of the cable the phone shows cable charging 

I have fast charging enabled in settings 

When I try to connect the phone to my computer it connects and disconnects  rapidly

I have never dropped my phone into water but one day suddenly moisture detected message started popping and after that all this is happening 

I have tried other cable that came with my S10 plus

But it was of no use 

Please help me if someone had a similar issue
