Estranho. Parece que tudo isso se resume ao nome de código do Android - por android.os.Build.PRODUCT e de acordo com este post ; ênfase ousada é minha:
A purported benchmark for the LG Nexus 4 appeared at GLBenchmark this week, showing us some of the dirty details that we were still hoping to get clarification on before the product is unveiled next Monday.
First off, you’ll notice that we have a device name of “mako” which has been known as the codename for some time now. Second, you’ll notice the word “occam” in the build fingerprint and product, another name that has been tossed around. In fact, a couple of weeks ago, the tin foil hats came out, and a group of Android enthusiasts jumped to the wild conclusion that there was a better-than-average chance that this was going to be a separate Nexus, probably built by Motorola. You see, because if you Google the term “occam,” you’ll find “Occam’s Razor.” Apparently, that should mean that occam equals RAZR, which equals Motorola phone. Wild, I know. This benchmark, if legit, debunks the hell out of that.
“Occam” in this case is the build product, a second name attached to all Nexus devices that refers to software builds. For example, the Verizon Galaxy Nexus runs under codename “toro,” but it’s software builds fall under the name “mysid.” For all GSM Galaxy Nexus variants, you’ll see codename “maguro,” however, each version has a different software build codename like “yakju” or “takju.” Make sense? So “occam” simply ties software to the LG Nexus 4, which is known as “mako.”
Verificando aqui no a página oficial do Google Developer para "Imagens de fábrica para dispositivos Nexus" que "navalha" é o codinome do Nexus 7 [2013] (Wi-Fi).
