Nokia 6.1 plus smartphone not charging | How to solve ?

A client had charging problem with his Nokia smartphone, when he took it to a smartphone service center, technician there replaced the sub-board and the phone was working fine but around after a week the phone started intermittent charging issue and customer again took it to the same service center, this time technician placed some rubber pieces inside the charging socket and showed customer that the phone was charging, the next day customer was unable to connect the charger and phone was not powering ON and he brought the phone to my workshop, this video shows what was the problem and how it was solved.
Take care and do the reparation on your own risk.
Thank you for watching, have a GOODTIME....
