On March 15, 2013, Beijing time, Samsung officially released the highly anticipated fourth-generation GALAXY S family member: Samsung GALAXY SIV in Times Square, New York, USA. As an annual masterpiece in 2013, Samsung GALAXY SIV's configuration in all aspects belongs to the flagship level, and Samsung has high hopes for its future market performance.
The eight-core processor is controversial, but the results are impressive.
Samsung GALAXY SIV is equipped with 1.8GHz Exynos 5410 octa-core processor released by Samsung early this year, and is equipped with 2GB RAM memory. Although Samsung Exynos 5410 is nominally an eight-core processor, it actually uses a large and small core design (four A15 architecture large cores + four A7 architecture small cores). The small cores work when the task load is low to achieve savings The effect of power and extended battery life. Although the competition has a bit of rhetoric about this design, we can see in the running test that Samsung GALAXY SIV has outstanding performance and a clear lead.

Replacing the graphics chip has an amazing effect.
Samsung GALAXY SIV's GPU performance is also very impressive. This may be related to Samsung's abandonment of the ARM Mail graphics chip it has been using and its switch to ImaginaTIon's latest Power VR SGX 544MP3 GPU. Power VR series graphics chips have always been the components used by Apple on iPhone, iPad and other products. For example, iPhone 5 uses PowerVR SGX 543MP3 GPU. The GPU of Samsung GALAXY SIV is more advanced from the model point of view, in fact it is the same: not only the support for Microsoft DirectX 9.3 standard is added, but the working frequency is also improved.
The system is smooth and there is no major UI innovation.
Samsung GALAXY SIV is equipped with the latest Android 4.2.1 operating system, which runs smoothly with strong hardware support. But unfortunately in the UI design, the machine still continues Samsung's previous UI style, and we can't see a breakthrough like HTC in HTC One (Sense UI 5).
The fineness of the 1080P screen has soared, and it supports floating touch.
Samsung GALAXY SIV uses a 4.99-inch 1080P Full HD Super AMOLED HD screen, which has a greater degree of refinement than GALAXY SIII. Samsung also introduced a brand new technology on the GALAXY SIV screen: floating touch. This technology has appeared on Sony's MT27i. The user's finger is close to the screen, and can be perceived and operated by the mobile phone screen without the need for a touch screen.
The 13-megapixel low-light environment is worth looking forward to.
On the HTC One phone released not long ago, the new camera technology and low-light environment camera performance became one of the main highlights. Combined with the fact that the Samsung GALAXY SIII's photo taking effect under low light is unbearable, the camera performance seems to have become another highlight of GALAXY IV. On the Samsung GALAXY S IV, Samsung is equipped with a 13-megapixel Sony Exmor lens, which uses a stacked structure to obtain better light input in low-light environments, ensuring brighter photos. This is obviously a targeted modification to the short board of the previous generation in taking pictures.
The intelligent operation function is good, but the actual application effect needs to be improved.
Among the smart operation options, Samsung GALAXY SIV is undoubtedly the most attractive to support eye detection and eye movement operations. However, in terms of actual experience, the stability of SIV for eye detection still needs to be improved. Automatic scrolling and smart stop for mobile phones and The position of the human eye is very high, and it is generally effective in the range of plus or minus 60 degrees. If it is out of this area, the angle between the front camera and the human eye is too large to be recognized, so there are many misoperations.
The COB light series is a main light that improves the brightness of the stage lighting. The COB light with the focus function can be switched between the function of concentrating bright light and emitting soft light in a large area, so that it can meet the requirements of different brightness and spotlight on the stage. need. The difference between COB and other series is that white light and warm white light are mainly used in color, which is the main source of light on the stage, stand an important position on stage.
