Anyone have charging port issues?

I use a Samsung S6 edge plus and all of a sudden the charging port on the phone wasn't holding the charging cable snugly and the cable was very loose and i started facing issues with charging Found a simple solution that worked great. Took a safety pin and cleaned the charging port on the phone carefully without moving the internal part. I could see a lot of lint and dust accumulated in the socket due to the phone pushed into the pockets. Once cleaned, it is back to working perfectly.
 
I have had no problems. But my son has a V10 also and he can't even charge his phone.
He has the second battery and cradle, that is how he charges.......
He is waiting to see what the V20 holds or he might go with a Note 7.

Lateck,
 
I notice that some non-oem cables will fit looser than the oem ones but they still seem to work for now.
