The s8 is slippery as hell and very fragile. My screen cracked after just a month. Replacement is crazy expensive.
Unless s9 changes that, don't buy it!
Yeah the s8 is insanely slippery. I put a concrete dbrand on the back of mine just so I could pull it out of my pocket and not toss it half way across the room. I'll never understand the all glass trend.
I think Samsung and other manufacturers can't win there. People complained about the perceived build quality when their flagships had a plastic body. Unless you use harder and thicker polycarbonate (like the Lumias or the iPhone 5c) it's hard to have something that truly lasts. You're left with aluminum, which brings tons of problems (it's easy to bend, scratch, the anodization will fade, it feels cold and it's also slippery, and you need to make way for antennas), or glass.
Repacking the display is near impossible because there’s no frame around the display and everything is glued which means trying to open you nearly invariably break the screen.
