The latest installment in Samsung’s Galaxy series, the S6 Edge, flaunts a curvy figure and slim body that’s sure to bring all the boys to the yard. But it’s like Mama always said: Beauty is more than just skin-deep.

In the depths of this edgy, intergalactic gadget we discovered glue—lots and lots of glue. The rear panel is stuck on rock-solid, and then there’s that display glass. We peeked into Samsung’s manufacturing chain, and found their curved-edge glass supplier apparently has a 50% yield rate—meaning only half the glass they produce can be used in the Edge. No word as to how (or if) they are recycling all that wasted glass—but there’s still a huge environmental cost tied to production that can’t be offset.

Due to the stubbornly-glued battery sandwiched under the midframe, gratuitous glue, and the high probability of destroying the display during glass replacement, the Samsung S6 Edge earns a repairability score of 3 out of 10. That’s one small step for Samsung. One giant leap backwards for the Galaxy.

Teardown highlights:

• Unlike in every previous Galaxy S phone, the battery is very tightly adhered to the back of the display, and buried beneath the midframe and motherboard. Now you gotta unglue and unscrew. RIP user-replaceable battery.

• In the connectivity department, Samsung seems to have given up its edge. Gone is the USB 3.0 connector of the S5—in its place we find a standard microUSB port.

• According to Samsung, the curved glass is created by a process called 3D thermoforming, a process of heating and molding the glass. While it looks cool, it comes at a cost—in this case eight times the cost. That’s right, what was once a $3 part could now cost as much as $26 due to low yields. Not to mention the environmental cost.
