In Germany, juvenile detention is up to 24 years. Juvenile law is also not that straightforward, if it’s applicable also depends on how “childish” someone still behaves. In some cases one can be 20 and still go to an adult prison, e.g. if they’re very violent and wouldn’t fit into the education-oriented juvenile detention. On the other hand, older people who behave very childish (e.g. because of a disability) will usually not be put into an adult prison and instead get something more therapy oriented similar to juvenile detention.
There is no standard what red USB A ports mean. Could be fast charging through some proprietary protocol or other special features. Or just a design choice.
USB ports with no symbol just don’t advertise what they’re capable of. Most phones support super speed data transfer. Basic USB-PD and display port output support is also common. They may also support other stuff, like pretending to be a webcam, audio output and much more. But you usually have to look in the manual or data sheet to know what is supported.
