I have a UAG case on my Samsung S8 from the day I brought it home. I noticed after a month the back glass, under the case was cracked. About 3 months in the phone fell from my bathroom counter into the garbage can, hitting the edge of the rubber can on the two foot drop, cracking the front screens edge.
As much as I would like to think "don't drop it" is the answer, it's not practical in the real world and I don't think there's a quality care that protects the phone without interfering with the edge technology.
I hate the curved screen and won't buy another one. I buy phones for screen and photo quality, personalization and durability. Clearly you'll have to compromise something in the final decision. I'll no longer take durability so lightly and all the phones, with user training, can take excellent pictures and have decent screen quality.
Buh-bye Samsung.
