Samsung S10. S10 Plus and S10e use the same charge port, which is soldered to the motherboard but the way it is made to hide the soldering connection pins. so you have to heat up the motherboard, not the charging port. There are many small components on the motherboard around the charge port. that makes it almost impossible to replace. 

This may be replaceable at Samsung unauthorized repair shops but a charge port repair requires a motherboard replacement or a mail in repair to Samsung. (This is because Samsung does not allow soldering to be done on their devices at authorized repair centers.)

But don't worry, Our technicians at Cell Phone Parts Canada have the capability to replace the charge port on Samsung S10 phones. Please contact us for quotation.
