G3 is the latest flagship mobile phone of LG. It is the first mobile phone with 2K screen used by foreign brands. It has 5.5 inch 2560 * 1440 IPS screen, Snapdragon 801 2.5GHz, 3G Ram+32G Rom and other high-end configurations. The rear camera uses 13 million pixels with OIS and laser focus. The camera sensor it uses has always been controversial, some say IMX214, others say IMX135. Today we will explore with you:

Just got it Korean G3 When we found the drive file of imx214 in the/system/lib directory of the system file, we guessed that the G3 used Sony's second generation stack sensor IMX214 ▼

Later, some people questioned this judgment method, and some people used the method of capturing log files to verify that G3 used IMX135. In fact, the method of viewing the driver file and capturing the log file could not fully explain the problem, and was not convincing. The simplest way to correctly judge which sensor G3 uses is to dismantle the camera directly, but we also know that the sensor model of the camera is not exposed, and the entire camera needs to be packaged with a mirror set. Generally, the camera sensor model will not be seen when disassembling the camera, so we have to find another verification method.

In fact, we can view the boot information through the dmesg command, and search the actual model of the sensor in the recorded information. The method is as follows (Korean version G3 and model F400S are used in the test):

First, you need to obtain the root permission of G3, and then install the corresponding driver on the PC side. Then open the ADB tool and open a command window. Type "adb shell su - c dmesg | find/i" sensor ". This command means to find the keyword sensor in the boot up information, and then find the camera sensor information we need from the results. Before typing the command, we need to turn on the G3 camera, so that we can record the information when the camera is turned on. The result is as follows:

As can be seen from the red line in the figure, the sensor named imx135 was started twice, and the sensor named imx208 was started once. Although we can also see imx214 in the information, there is no startup information. So we can judge that the Korean version G3 uses an IMX135 stack sensor in the rear and an IMX208 back lit sensor in the front. The mystery has finally been solved. LG's new flagship unexpectedly uses the stack sensor of the previous generation, which is disappointing. However, from the actual photo taking effect, the G3 is not inferior to some mobile phones that use the IMX214 sensor, which also reflects LG's optimization level in camera.
