I appreciate your unimpressed with what has happened with your phone.
A phone's screen can be damaged from low drops depending on the angle it hits the ground and with curved display edges these can be weak points.
This can happen to any phone not just Samsung mobiles.
This is why I too have a screen protector on my phone which is a Whitestone Dome Glass Screen Protector and a case.
I prefer a minimalist feel so I choose the Samsung Black Leather Back Case.
This gives some protection to the edges if the phone is accidentally dropped.
Having the displays replaced on these phone's isn't a cheap affair due to accidental damage not being covered by the manufacturers warranty.
Insurance cover is an option to take some worry out of accidentally damaging a phone.
I wish you all the best with this.
