Screen

Touch Screen Type capacitive screen, multi-touch Now are capacitive multi-touch, if you are afraid of being cheated, simple verification: with a relatively sharp thing, touch the screen, if the touch is not capacitive, if you want to push down, is the resistance. Main Screen Size 5.1 inch screen Size There's nothing to talk about, it's about the length of the diagonal. 1 inches is about 2.54 centimeters . Main screen Material Super AMOLED HD Screen material, screen material a generation of forward development, in fact, as long as it is not too bad, the human eye can not feel it. Sales said to the eye good, basically is the nonsense. Home Screen Resolution 1920x1080 pixels Can understand the mobile phone screen is a lot of very small blocks, resolution is said to be the horizontal and vertical direction of the phone, the screen by how many small points, you can imagine, the same length inside points more delicate, so-called Retina screen, is the human eye has not been able to see the size of the pixel, metaphor and its fine. The bigger the better screen pixel density 432ppi In relation to dimensions and pixels, the meaning is pixel per inch, that is, how many pixels per inch, obviously the bigger the better. Narrow Border 4.5mm screen Percentage 69.65%

Network

Network Type capacity is 4G Network unicom td-lte 3G Network unicom 3G (WCDMA), Unicom 2g/mobile 2G (GSM) Support Bands 2g:gsm 850/900/1800/1900 3G:WCDMA 850/900/1900/2100mhz Network type is more important, and some businessmen will deceive you that the machine is 3G, or quasi 3G, in fact, only on WiFi. 4G 3G 2G, the big brand will not talk nonsense, to shop to buy verification, with the salesperson to a corresponding card, lay the phone to verify, of course, can also go online to see the speed of the network. WLAN Features wifi,ieee 802.11 a/n/b/g/ac,mimo WiFi smart computers have, authentication can be networked, A/n/b/g/ac actually doesn't matter. Navigation GPS Navigation, A-gps technology, GLONASS navigation GPs need to navigate the words or needs, A-GPS is actually auxiliary positioning, that is, base station positioning, not what positioning. GLONASS is a similar U.S. GPS positioning system in Russia. Connect and share NFC, infrared remote control, WLAN hotspot, Bluetooth 4.0 NFC is becoming more and more important, that is, near-field communication, is a necessary future. The infrared doesn't matter. Wi-Fi hotspot to experiment with, is someone else can link you, you as a router. Bluetooth 4.0 is Bluetooth.

Hardware

Operating System Android OS 4.4 The newer the operating system, the better. Number of cores Four cores The core number to say: Manufacturers are hard to beat the multi-core card, in fact, the 8 core has reached the multi-core limit, more than the waste electricity is no use. In fact, I think that the 4 core is OK, of course, 8 core is correct, the actual experience is not determined by the core 4 or 8, the experience is a comprehensive new energy. CPU Model Qualcomm Snapdragon Dragon 801 CPU Frequency 2560MHz GPU Model Qualcomm Adreno330 CPU model also need to say that the high-pass CPU is very good, it can be said that the best, you will say how Apple, Apple is also good. CPU model determines the performance of the system, unlike a PC, graphics card can be equipped with, mobile phone, a complete set of chips, so the overall system performance is here. Other 8 cores are not necessarily better than the 4 cores. GPU is the meaning of the video card, exactly the same, run the shape points to see can. RAM Capacity 2GB ROM Capacity 16GB Needless to do, the larger the RAM and rom the better. RAM is the most critical, the bigger the better, you can sacrifice rom for large RAM. Memory Card microSD card Extended Capacity 128GB Can support SD card is critical, in case ROM is small, and can not expand, it is miserable. Battery Type removable type battery Battery Capacity 2800mAh Battery capacity In fact, it doesn't matter, can not be used for a few days, also day

Webcam

Webcam built-in Camera Type Dual Camera (front and rear) Rear camera pixel 16 million megapixels front-facing camera pixels 2 million megapixels Sensor Type Isocell Flash LED Fill Light Aperture f/2.2 Video Capture 4K (3840x2160,30 frames per second) video recording Photo function Time- lapse selfie, continuous shooting, auto focus The camera directly look at the effect, pixel with the higher the better, but do not decide the quality of the photo, the specific experience it.

appearance

Styling Design Bar Body Color black, white, blue, gold Cell Phone Size 142x72.5x8.1mm Phone Weight 145g type of Operation Physical Keys Conformal function I67 Rating Sensor Type gravity Sensors, acceleration sensors, light sensors, distance sensors, fingerprint recognition, heart rate sensor SIM card Type Micro SIM card Fuselage Interface 3.5mm Headphone interface, Micro USB v3.0 Data Interface Shape is more important, the size of the headset mouth 2 kinds of attention to the difference, what 3 anti-normal basic use. Gravity sensors are used to automatically turn the screen and the game, the accelerometer is basically combined with gravity. The light sensor is used to automatically adjust the brightness. Heart rate sensor detects heart rate. There's no use in fingerprint identification. Now, it may be. The distance sensor calls the auto-kill screen.
