There're Xiaomi Mi 5 Schematics & Layout above the page.
The main camera Mi5 attributed to the shortcomings is simply impossible. Xiaomi had to arrange a battle with the Samsung S7 camera in terms of speed, it was these two devices in “automatic mode” that took pictures fantastically fast. At the same time, both focusing and saving the image itself quickly occurred.
As for the software part, but in the case of Xaiomi, the rule “saw one, then saw everything” works. In terms of response speed, the MIUI of the Mi5 interface works as expected "instantly", but without overtaking, for example, my Mi4c - in order to feel the "power" you will need to install games or other demanding applications.
