Sam Galaxy S3.

Different phones tend to have specific problems. Also, are you doing
anything unusual while charging, such as charging the phone while it's
sitting on a car seat while bouncing down the road or anything that
might cause movement of the connector while charging? An excessively
loose connector will make that worse. You might compare your
retention force with a different phone and micro-USB connector pair.

I use it while charging, sitting on the couch or lying in bed. The
cable/phone does get moved around. But for 6 weeks this isnt a problem. So
I rule out the phones connector as cause. A new cable fixes the issue.

Thanks.
