Mobile World Congress 2019 is the largest mobile industry expo in the world which was held in Spain on Feb 2019. The Chinese market being one of the larger markets with its own set of exclusive devices from various company receives its very own MWC at Shanghai which is scheduled for 26th to 28th June. OPPO one of the well-known smartphone manufacturers has confirmed its attendance at the Mobile World Congress 2019 on Weibo. A poster shared by the company clearly indicates that it is planning to launch the first under-display camera in the world.
Under-display camera smartphones essentially have its front camera within the front display but unlike a punch-hole module cannot be seen. The screen entirely encompasses the front panel with the camera under it. Earlier this month, Oppo had showcased its first functional prototype to the world, as did Xiaomi. Most OEMs have adopted a pop-up camera (like OnePlus 7 Pro) or rotating camera modules (such as Samsung Galaxy A80) for the full display solution. These are currently almost exclusively found in top-end or high mid-end range smartphones.
A short clip was previously shared by an OPPO executive which showcased a smartphone with the praiseworthy feature. It is uncertain if the aforementioned device is a prototype that is under development or an initial version of a smartphone that would be available commercially. The device had no visible seam for a front camera and had a full display panel at the front. This has probably given the world its first look into completely bezel-less smartphones.

However, these innovational strides in the industry are always a positive sight.
The Micron c200 1TB microSD has a lower read speed than Western Digital’s offering. The read and write speeds are clocked at 100MBps and 95MBps respectively. It employs the Dynamic SLC cache and performs automatic resource management for sustained peak performance. Just like the Sandisk’s 1TB card, it also follows the A2 specification. The card leverages Micron’s 96 layer 3D quad level cell (QLC) NAND technology for faster speeds. Both these cards are expected to be helpful in providing efficient storage for 4K videos, pictures and games on smartphones and other electronic devices.

The G8 ThinQ stands out owing to its glass-sandwich design built around a metal frame. Glass panels adorn both the front and the back of the device, which are protected by Gorilla Glass on both the sides. Interestingly, the rear of the device has Gorilla Glass 6, while the display is covered by Gorilla Glass 5. The bezels are thin, but not thin enough, giving the G8 an 83.5 percent screen-to-body ratio. 
The G8 ThinQ runs on a 7nm Snapdragon 855 chipset, which comprises of an octa-core processor (1×2.84 GHz Kryo 485, 3×2.42 GHz Kryo 485 and 4×8 GHz Kryo 485) and the Adreno 640 GPU.

The device has a 3.5 mm headphone jack, which lies next to the USB Type C port and a ‘grille’ at the bottom of the device. One of the highlighting aspects of the LG G8 ThinQ is the resonating panel that can produce sound. Known as the CSO (Crystal Sound OLED), LG claims that the panel act as stereo speakers and adds an acoustic touch to the sound quality. Moreover, the CSO also acts as an earpiece for receiving phone calls, so users can literally listen to any part of the screen while conversing. The beforementioned ‘grille’ may be a part of the resonating chamber beneath the screen which is used to redirect audio. 32-bit Hi-Fi Quad DAC is integrated with in addition to DTS:X 3D Surround Sound for headphones. The device packs a 3,500 mAh battery which supports Quick Charge 3.0. It is also IP68 dust and water resistant and meets 14 MIL-STD 810G standards, which means that it can survive drops of over 8 feet without taking any damage.
The LG G8 ThinQ has support for Portrait Video Recording in the front camera. It is really intriguing to see how the device will record videos with the bokeh effect. Also, as mentioned previously, the handset has a front facing 3D ToF sensor. Positioning it at the front ensures more functionality from the sensor. Also called the ‘Z Camera’, it claims to be more precise than a dot projector and faster than Apple’s current ‘Face ID’ technology. Also, the ToF sensor can capture an accurate image of a user’s palm – complete with wrinkles and the blood flowing through the veins. Since every person has unique wrinkles and veins, placing the hand in front of the sensor will instantly unlock the smartphone. It can also be used for hand gestures to control various apps in the device. It is still unclear how practical can this be, but sure, it’s an example of ‘useful innovation’ by LG.
