Samsung Galaxy S6 Repairability Score: 4 out of 10 (10 is easiest to repair).

Many components are modular and can be replaced independently.

The S6 doesn't have the S5's display-first entry, but the display still needs to be removed if you want to replace the USB port.

Unlike the S6 Edge, the battery can be removed without first ousting the motherboard—but tough adhesive and a glued-on rear panel make replacement more difficult than necessary.

Front and back glass make for double the crackability, and strong adhesive on the rear glass makes it very difficult to gain entry into the device.

Replacing the glass without destroying the display is probably impossible.
