imo, samsung has some great products but their warranty is not one of them. I have read nothing but horror stories of them weaselling out of honoring their warranties. I have been fortunate, I have not damaged any of my galaxy note phones over the years. No dings, dints, scratches etc. I don't even use a case or screen shield. I am extremely careful. at least they are not like apple, honor the warranty but send you a bill because they fixed all the other damage they found claiming they had to fix everything in order to do the warranty work.
as far as dropping damaging a mother board, something could shift inside the phone on impact and damage the mb. maybe they could see the shift or the dent is where the mb fault is and assume that caused the problem. who really knows.
I have been an avid Samsung Mobile Device user for the last 10 years up until today.
My frustration started when my Samsung A8 2018 model was sent in for repair after a year. The technicians found that the motherboard is faulty (which is covered in warranty). However, after many discussions Samsung has voided my warranty due to physical damage of the phone and thus will not repair my device.
To confirm my device has fallen on the floor. However my device has a screen protector and I am still using the Samsung phone cover that I received with my device when I signed my contract a year ago.
Please can someone explain to me how do you prevent your phone from falling and getting scratches and dents.
More importantly how do you confirm that due to the physical damage that is the reason for the faulty motherboard.
I am sure I am not the first person that this has happened too.
