Information on 5x zoom and 120 Hz refresh rate found in MIUI 11 beta

Apparently, Xiaomi is preparing to create a new smartphone with a 5x optical zoom and a screen with a refresh rate of 120 Hz. At least, these technical data were found in the code of the test version of MIUI 11.
So, in the operating system there is information about a certain Tele 5X mode, which, most likely, indicates that in one of the new Xiaomi smartphones there will be a telephoto lens that allows you to shoot with a 5x zoom. Mention is also made of the ultra tele mode, which is rumored to allow the use of a 50x digital zoom.
The developers of the XDA Devlopers portal found in the code a mention of the possibility of switching the display to 120 Hz mode. Previously, displays with a high refresh rate were used only in gaming smartphones, but times have changed, and the ability to turn on the screen in 120 Hz mode does not mean that the gadget will be gaming.
