And it already seemed that Samsung will be the first producer in the world to introduce a smartphone with a so-called screen hole. It turns out, however, that the title of the precursor will fall to Lenovo, because it is this Chinese manufacturer is going to show its novelty on December 6 this year.
After the indentation in the screen in 2018, the time has come to raise the bar and market smartphones with displays that fill almost the entire surface of the front panel and reduce the indentation to a minimum by using a hole in which the dedicated Selfie camera is mounted. Until recently, it was thought that the first smartphone would be presented by Samsung. Quite loudly after Galaxy A8s, which is to be shown on December 10 this year. The second producer was supposed to be Huawei with the Nova 4 model, whose premiere was planned for December 17th. https://youtu.be/FzKF4VP7QB0 Lenovo, however, decided to brace the competition and the phone with the In-Display camera will be presented on December 6 this year. This will be the Lenovo Z5s . The position of the opening for the Selfie camera, however, seems more traditional, because it has to be in the central point at the top of the screen, instead of in the upper left corner. The Lenovo Z5s have a very thin frame at the top and a slightly thicker chin at the bottom. After all, the Lenovo Z5 Pro is already impressive in terms of screen coefficient to the front panel surface (95%), but the Z5s is to be even more impressive . The notch in the O-shaped display should be less annoying than even a drop-shaped notch. https://www.gsmmaniak.pl/916680/oto-lenovo-z5-pro-piekny-smartfon-z-niesamowitym-screen-to-body-ratio/ In terms of photographic opportunities, the Lenovo Z5s should not disappoint because on the back wall three camera modules will be placed. However, there is still no information on the resolution of the three rear cameras, as well as the general characteristics. The smartphone is expected to display content in FHD + resolution on a 6.3-inch screen with an aspect ratio of 19.5: 9. The display is to be produced by BOE, similar to Samsung Galaxy A8s and Huawei Nova 4 . Unfortunately, the equipment will run out of the biometric sensor in the display, which is moreover confirmed by graphics published by TENAA. This protection will appear on the rear panel. 
Supposedly the heart of this model is to be Qualcomm Snapdragon 675 produced in an 11-nanometer lithographic process. The Snapdragon 675 system uses Kryo 460 processor cores based on the ARM Cortex-A76 microarchitecture. The chipset uses two high-performance cores with clock speeds up to 2.0 GHz and six cores clocked up to 1.8 GHz. Energie has a battery with a capacity of 3210 mAh. The components will be enclosed in a housing with dimensions of 156.7 x 74.5 x 7.8 mm. source | source
