Myce.com got their hands on a log from the Nexus 5 (also called LG D820 and Hammerhead) and AndroidWorld.it dug though it. Some 133 thousand lines were searched but the reward was probably worth it - a number of interning specs for the upcoming pure-Google phone were confirmed.
Most of the stuff is no surprise a 5" screen (actually, 4.97") with 1080p resolution, 442ppi pixel density, a Snapdragon 800 chipset with 2GB of RAM and 16GB storage (on that concrete model, there might be others with more and hopefully not less storage). The phone ran Key Lime Pie (a.k.a. Android 4.4 KitKat), build version KRS74H.
It seems that the camera has been changed to an 8MP snapper (the Nexus 4 also got a lower-res camera than the Optimus G it was based on). It's too early to tell if there will be optical image stabilization (probably not though). There's a 1.2MP front-facing camera too.
The Nexus 5 will pack dual-band Wi-Fi a/b/g/n/ac, Bluetooth 4.0, NFC and GPS connectivity. The model whose log file leaked ran on North American LTE bands, but we should expect a Euro version too.
The phone will have wireless charging built in and while battery capacity wasnt in the logs, FCC docs point to a 2,300mAh unit. There will also be a full set of sensors accelerometer, magnetometer, gyroscope, proximity and light sensors as well as a barometer. The FCC measured the phone at 131.9mm tall and 68.2 mm wide, there's no info on thickness.
A case maker, SPIGEN, puts the Nexus 5 launch date at October 31, a month from now.
Thanks for the tip, Emanuele!
