First of all, the appearance of LeTV U4 is very different from previous generations of products. The most intuitive feature of U4 is its thinness. The narrowest point is only a little over 10mm, because the mainframe is smaller and thinner, so the corresponding interface is also streamlined. Quite a lot, but it can fully meet the daily entertainment needs. The overall appearance is more like an artwork at first glance. 
Configuration will no doubt support 4K video playback, equipped with Android 6.0 system, 2GB DDR3 memory, storage 8GB eMMC, support H.265 hard solution and 3D and so on. On the processor side, H.265 has strict requirements on hardware. The GPU uses five-core Mali-450 @750Mhz. The top intelligent box chip Amlogic S905 adopts Cortex-A53 architecture, which is 25% higher performance than the previous generation. With HDMI input TV, monitors, projectors, amplifiers and other equipment. Support 802.11a/b/g/n/ac, 2.4GHz/5GHz dual-band WiFi, support the latest Bluetooth technology 4.1, more stable than the previous generation, less delay, lower power consumption. 
As for the content aspect, because we have access to the CIBN license, we have plenty of content resources for everyone to watch. We don't have to worry about it, but some friends are more concerned with how LeTV U4 installs third-party apps to see more free hot movies. I will use the “Sofa Manager†as an example to tell everyone how LeTV U4 will install third-party applications. Other applications can also refer to this method.
The whole process only takes three steps:
The first step: go to the sofa butler official website to download an installation package to the U disk. 
Step 2: Connect the U disk with the installation package to the UTV box U4. 
The third step is to click the installation directly after identifying the installation package. 
After the sofa butler is installed, download the TV cat through the client, magic video and other applications can watch large movies for free ~ Isn't it simple? 
The happy UTV box U4 finally met with everyone. The one-year membership version sold in Jingdong only costs 590 yuan. For the two-year domestic market, the price of the LeTV box is relatively close to the people. It's up.
