Hello @Giby sorry to hear you are having this issue, if it's only the back glass that needs to be replace you should visit one of our Samsung Repair Centers. Check this website to find the nearest store near you. https://www.samsung.com/us/support/service/locations
If it makes you feel better my S20 slipped off an arm rest on a laminate floor and broke the rear cover.
UbreakIfix replaced the rear glass with a Samsung factory part for $109.
Thr S20 is a $1000 egg.
