Lenovo VIBE Z2 Pro K920 performance Review-Latest 6.0 Inch RAM 3GB Smartphone
From the deep review on Lenovo K920 display and design, although this smartphone has some shortages on the details of the display and design, the all-metal design quality and significant progress can meet our needs of pursuit of flagship. How about its overall performance? About its Snapdragon 801 Quad Core 2.5GHz, RAM 3GB, 2K screen, and other high-level configurations, i can’t wait to have a good experience of it.

Overally, 2K screen, top-level core, all-metal screen body and so on are all the eye-catching outside features. But opitimization of system, better gaming experience and so on are the main mission that Lenovo needs to improved.


Basic Configurations: 6inch 2560*1440 pixel 2K IPS screen, 156mm×81.3mm×7.7mm dimensions, Android4.4 OS, Qualcomm Snapdragon MSM8974AC Quad core 2.5GHz CPU, 3GB RAM 32GB ROM, 4400mAh battery, 16MP Back camera and 5MP front camera.

Game testing

“Need for Speed ​​17″ Result: Smooth, occasionally flash back
“Little yellow people Run” Result: Very Smooth
“Mass Effect” Result: Smooth

Advantages: 2K screen, colorful, high brightness, large viewing angle
VIBE UI2.0 rich functions
Body heat control better when play games

Disadvantages: A little dull when touch screen
Game flash back, optimize inadequatly
Too complex UI interface color

Beautiful and high-standard 2K screen

Lenovo K920 is the fifth 2k screen smartphone until now in the market. 6inches screen size is simliar to the earlier Vivo Xplay3S,which is also the largest 2K screen smartphone currently.Such high screen resolution not only makes naked eyes see the words without any pixels, thanks to the LTPS technology of 630nit super-brightness. And outdoors there is no problem to see the screen in sunlight. IPhone 5 also used LTPS IPS screen, its advantages are high-brightnes, low-power consumption, larger viewing angle, colorful screen and so on. With the screen resolution improving, Lenovo K920′s screen has the clearer image color effects. I didn’t find the dull touch screen.

In system, probably to show the advantages of the 2K color screen, Lenovo K920 VIBEUI 2.0 choose the colorful wallpaper, the icon color is also very rich,but it also seems a little complex in color and make users a little dazzle. The lock screen widget can switch directly the wallpaper, which feel a little useless. Slidding upper is the action of unlocking the screen, but the bottom provided quick entrance of calls, text messages, cameras,which also need to move upper. Therefore, we will be confused about these functions. Sometimes, i want to lock to the main interface, but it goes through directly the interface of texting messages. Additionally, on a 6-inch screen, a single-page application icon design for Five four columns (plus a total of six lines dock bottom bar), which is a little large and waste the space, i think, the setting fonts of contact persons and text messages are a little large, we need to set up again.

The score of the game is high, but flash back happens

To manage 2K screen, Lenovo K920 is powered by Snapdragon 801 Quad Core 2.5GHz processor with and 3GBRAM, which is currently the top configuration, as well as Antutu Benchmark test and 3D Mark score points can be seen. The processor’s performance strength has also been introduced many times, I will not repeat them here. In fact, the parameter is not important, hardware optimization is reflection of the strength of manufacturers. Although Antutu Benchmark test score ran up to 38000 points points, but K920 flash back happens occasionally in playing games.

In our testing of the games, “real racing 3″ “Need for Speed ​​17″ “X-Men” have emerged in the case of flash back, which is probably caused by insufficient 2K screen optimization. Under normal circumstances, K920 quality performance is still quite good, large racing games playing didn’t feel significantly dropped frames, “Crazy Taxi,” “little yellow man Run” and the other kind of 3D games run very smooth and fast.
I should worry about the heating problem when i play large games, but the heat control of Lenovo K920 is quite good and out of expectation. After playing “Need for Speed ​​17″ in ten minutes, the temperature of the smartphone is within an acceptable range. there is no problem of hot heat issues.


Overall, the performance to play games is quite remarkable. This lenovo k920 is really the flagship of Lenovo. If you want it at a good price, just check in 1949deal now!
