A friend of mine brought his relative's SAMSUNG galaxy A52 smart phone and told me that it is not charging after it fell down, disassembling it was not so tough as the back cover had come out by itself because he had kept his phone on car's dashboard, this video shows how the not charging problem was solved without resetting, without loosing any data.
Please note that this method solves many of the problems(not powering, not charging etc...) occurring in almost all brands/make and models of android smart phones. I haven't tried this on IOS smartphones yet.
Take care and do the reparation on your own risk.
Thank you for watching, have a GOODTIME....
