There are lots of 3 XL Pixel reviews circulating from the outside and their capabilities. From the inside, it turns out that the Pixel 3 XL was found using Samsung-made OLED panels. This
finding was published by iFixit, the site of loading and unloading
gadgets, which released step-by-step articles and the results of copying
3 XL Pixel innards.
According to iFixit, compared to Pixel 2 XL, Pixel 3 XL has a screen that looks brighter and clearer. Previously Google also used Samsung's OLED screen for the first generation Pixel and Pixel XL duo, then continued to Pixel 2.
However, Pixel 2 XL (a model with a screen larger than Pixel 2) uses a POLED display panel made by LG which was reported to have several problems. The problem is that the LG POLED panel on the Pixel 2 XL includes a screen that looks grainy and feels dirty when the brightness level is low.
There are also reports that mention the burn-in problem, in which the OS's interface looks imprinted on the screen panel because it is left too long to be static, unchanged. POLED (Plastic OLED) and OLED actually have differences in terms of flexibility where POLED uses a plastic substrate, while OLED uses glass.
It is said that the use of plastic materials is what causes POLED display panels vulnerable to burn-in problems, as summarized by KompasTekno from ArsTechnica, Wednesday (10/17/2018). Returning to the 3 Pixel XL, iFixit added that the innards of the cellphone look quite similar to Pixel 2 XL. It's just that there are additional new components such as coils for wireless charging.
There is also a Google SR3HX "Pixel Visual Core" chip that functions to control various features of the cellphone's camera. The main camera sensor itself remains the same as that found on other flagship smartphones, the 12 megapixel Sony IMX363.
