Famous Google Nexus 4 is the fourth generation of a son, with its excellent value for money and the son's descent was welcomed by many users. Under the Nexus 4 shine, we seem to have ignored its "predecessor"--LG Optimus g, the phone has the Nexus 4 lots of similar design elements and more robust in the configuration.
Configuration of the Nexus 4 I believe members are very familiar with, we look at the Optimus g configuration:
Model: LG F180L (Korean version)
CPU: Gao Tongxiao S4 Pro APQ8064 quad-core 1.5GHz
Operating system: Android 4.1.2
Screen: 4.7-inch 1280*768 True HD resolution IPS screen
SIM card type: microSIM
Storage space: 32GB (not supported)
RAM:2GB
Connection: Bluetooth ®, Wi-Fi ® IEEE 802.11 a/b/g/n,Micro USB, 3.5mm audio interface
Camera: 13 million megapixel back-illuminated-F/2.4 apertures, front-mounted 1 million.
Battery: 2100mAh is not removable
Other: NFC
Mobile phone: 131.9x68.9x8.45mm
Mobile phone: 145g
See from the configuration, relative Nexus 4, Optimus g configuration of more powerful, 13 million pixel camera, 32G storage space is its advantage. Most encouraging is that revision machine market, Optimus g's market price to around 100 Yuan lower than the Nexus 4, price/performance advantage is obvious.
Optimus g and Nexus 4 for the twins, they are very small differences in shape, configuration, the paper was written by Optimus g relative to the Nexus 4 different parts.
Profile
Look on the positive side, is typical of LG Optimus g style, thanks to the fitting screen, coupled with almost invisible while touching the keys do not light up, so a positive look in addition to Logo and camera is black, which is now very popular "premium black" and, of course, by contrast, Nexus 4 there is no Logo is more low-key
Optimus g receiver
Nexus 4,Optimus g front than have three touch-sensitive keys, and the three keys to bring up the White Backlight, relative to the virtual key, what the users more easily accept the touch keys
Optimus g signal is relatively "cheap", the front-facing camera on the left side there is a small led lights, lights and Optimus in the Nexus 4 g Pro Home button lights are low
Optimus g founder, Nexus 4 round, both backs have a piece of glass, so special attention must be taken in using shatter-resistant. Their cameras and speakers are the same
The difference between back patterns
Optimus g thanks to the 13 million cameras, so the camera position will highlight the
Side Nexus 4 skin-like slip-resistant material, and Optimus g side uses the piano paint
Is also a high degree of consensus on the left side of the fuselage, namely volume, SIM card slot
Top noise-reducing microphone and 3.5mm interface and because Optimus g is of course Korean version, is an antenna
Is microUSB connector and the microphone at the bottom, of course, the iconic two large screws, many users find this Nexus 4 design flaw
UI
Because Optimus g official system used LG, Nexus 4 are using Google Android system because of their relatively large differences in systems and UI, of course, the system we are about LG Optimus g Pro as discussed in the evaluation, Google native Android is also a familiar system, here is a brief introduction about the Optimus UI of g.
Optimus g Pro, Optimus g Starter seem tighter, Optimus g Starter layout is 4*4, but Optimus g Pro 5*5, and Optimus g search field cannot be deleted
In the system menu, drop down basically the same bar, and Optimus g Pro, worth noting is that Optimus g without the function of QSlide apps
Initiator and lock screen can add lots of special effects, this is LG's UI features
Places to feature Optimus g is comes with a "quad-core control" option, which can open the Eco mode, open after this mode you can turn off two of the CPU core. We all know that APQ8064 's power and heat are more objective, this sets the CPU power can be controlled effectively, of course, need to sacrifice is CPU performance
25G free space is a big advantage for Optimus g
Performance
Like the Nexus 4, Optimus g also uses the APQ8064 1.5G with 2G Ram matching, difference is using LG Optimus g home systems, optimization of the LG APQ8064 and how is it? We look at performance measurement
Theory test
Rabbit test
Optimus g is a very "standard" APQ8064, more than 20,000 points
Rabbit 3D
In the test of the GPU, Optimus g good
GLBenchmark 2.7
GPU performance tests, in 2.7 version of the test, Optimus g and other APQ8064 devices to play much (Offcsreen frames: 14fps), but in version 2.5, Offscreen only 21fps (normal should be around 30fps), comparison of difference, here will be referred to below
BaseMark X
New GPU built in Unity 4.0 engine testing software, On-Screen mode Optimus g relative to the number of frames on the same level of Nexus 4 gaps, but in Off-Screen is more gap in test
Practical application
Sunspider Javascript the page test
Optimus g in the single-threaded test does not reveal unexpected and comparable to other phones using the APQ8064
Video software solutions
Video decoding software is also an important measure of CPU performance test project, the test project test multithreaded performance CPU, and video hardware solution is different, this is one way to test the CPU computing power. Testing here is a 1080P 60fps ref=16 MP4 video, Optimus g 23 frames number of frames, within normal limits
Game
Following test two mainstream games, Dungeon Hunter 4 30 is the average number of frames (maximum effect)
Some of the more complex scenarios, only an average of 24 frames, the screen appears
Real racing 3 29 is the average number of frames, frames
Modern warfare 4 average number 28, poor performance
Reduced frequency problems
You can see from the tests above, during the test involving parts of the GPU are prone to abnormal, this is what the reason? We can see by looking at the System/etc/thermald.conf of the CPU and GPU frequency control strategy
From the graph we can see that, when the temperature reached 42 degrees when CPU block knows 1188MHz,GPU down to 320MHz to 44 degrees, GPU is reduced to 200MHz. This explains very well why so many test results are not ideal.
In addition, through our Pro system information to view the CPU frequency, can be seen in modern warfare 4 CPU frequency keep most high frequency, but in fact only open running dual-core, this will to a certain extent affected the gaming performance of the play
Even in the opening duo, when Optimus g temperature is very high, screen the highest surface temperature has reached 45 degrees Celsius
When the phone is when the temperature is too high, soft video solution down will appear, as shown in the following figure, quad-core CPU fully open, but fell to 1.1G
Photos
Nexus 4 has always been relatively weak for the camera part and Optimus g camera is 13 million pixels, relative Nexus 4 parameters for better, the following is really making a comparison
Optimus G
Nexus 4
Comparison details
From this photo, Nexus 4 partial color problem is very severe, and screen painting is serious, sharpness is not Optimus g.
Optimus G
Nexus 4
Comparison details
This one is close to the two, but still can see the Nexus 4 noise Optimus g than serious.
Then one of the more "playing God" the idea, due to a high degree of consensus on the hardware, or even developer Nexus 4 BootLoader brush into the Optimus g, this means that the Optimus g can enjoy the Nexus 4 powerful brush resources, of course, brush Nexus 4 ROM directly will cause some minor problems such as 32G, and 13 million camera not working properly. While Optimus g itself has many AOKP, CM10.1 and other native style ROM appeared, which was greatly enhanced by its playability

Summary
Optimus g as the Nexus 4 "original", worthy in every respect the work of, compared to Nexus 4, photos are at a huge advantage, and LG's UI performance is satisfactory. Optimus g in terms of gaming performance, mainly GPU block causes, of course we can use some unconventional methods to solve this problem, but subject to the calorific value of the phone itself is large, even with these methods, are some of the symptoms, not the causes of the programme, the key issue is heating control and heat dissipation design is not good enough in itself. Daily use of LG's UI feels good smoothness is high enough, relative to the market price 2300, Optimus g is a worth buying the phone.

Chinese version of Pebble smart watches
A lot of people told me, after a fresh, their Apple Watch most commonly used is the "view alerts" and "view" these two functions. Pebble that two things can be done, and whether the iPhone or Android phone, are qualified for the job. Even if it is on a business trip, as long as a week, do not need to bring the charger.
