Samsung A40 Charge Problem


Hello every body,

I have same charge problem with lot of Samsung A40.

First change flex charging cable and work for 1 week or more times.
But the problem comes back.

I change the part again but it's same... Don' t charge.

The only solution is press the connector.
I checked the connection which is clean

Have you ever encoutered the same problem and what's the solution?

Thank you in advance
