When I try to switch to MIDI in USB, it doesn't work

First, you need to distinguish between HDMI inputs and outputs. Inputs are there for a screen to receive a signal and display this image. Outputs send signals. Not all devices have both. Your television certainly has an entrance, which also fits. But just because your smartphone has a USB-C port does not mean that it is also suitable as an HDMI output. If you are unsure, you should research whether your smartphone is suitable at all, which I do not assume.

You can find a more detailed explanation of this and alternatives on how to transmit your mobile phone screen wirelessly, including Here: https://www.stern.de/digital/technik/handy-mit-dem-fernseher-verbinden--so-gelingt-es-8723526.html

This means that your cable is probably not broken, it is only intended for another device.

And how do I get the cell phone picture on the television
