When to replace the charging connector on the Galaxy J7 2017

The charging connector on the Samsung Galaxy J7 2017 wears gradually with each connection. You will know it needs replacing if the phone no longer charges, even after testing another USB-C cable, or if charging only works in a very specific cable position. A faulty connector can also allow moisture to pass through and damage the motherboard. Replacement becomes urgent as soon as the phone no longer recognizes the charger, because prolonged lack of charge can completely drain the battery and lock the device.
