Days before the phone officially hit the market on April 10, the folks over at iFixit have torn open the Galaxy S6 Edge to reveal how its built and just how hard it will be to repair should anything run afoul during your ownership. Spoiler: it’s not going to be very simple to fix on your own.

iFixit found that the Galaxy S6 Edge has a USB 2.0 port — which we already knew — and said it seems pointless that Samsung included this instead of a USB 3.0 port with faster data transfer rates. It also said that the curved display costs $26, about 8x as much as a flat panel, which is just one reason why the phone is more expensive than the Galaxy S6 counterpart.

There’s some good news, however. iFixit said that “any components are modular and can be replaced independently,” but that lots of adhesive will make it plenty hard for Joe Consumer to get into the device on his own. “The battery is very tightly adhered to the back of the display, and buried beneath the midframe and motherboard,” iFixit explained, noting that any efforts to replace the glass panel will likely also destroy the display.

The site ultimately gave it a repairability score of 3/10, which means you should probably send the phone to an expert for repairs.
