Why does this get a lower rating than the Nexus 6? The nexus got a 7 and this got a 5.

In the Nexus 6 guide the back cover was glued on, this isn't the case with the OPO

In the Nexus 6 there were something like 22 screws holding the back on, theres far few with the OPO

With the Nexus 6 you complained that many parts weren't detachable like the MicroUSB port, in this phone many more components are attached via removable ribbon cables.
