Should a mobile developer be good at backend?

Question

Mobile development

The question is, should a mobile developer be able to develop an API on the backend and generally mess with it, or is this the competence of a backend developer? If he doesn’t have to, but he can, then this is a plus? Are there generally such "full stack" developers who do both?

Answer 1

Should not.
It will be a plus.

Answer 2

In my opinion, the simplest thing in an average project is the backend :) Modern tools allow you to do it in just a couple of hours.
I make both the backend, and mobile clients, and make my web version (though I really don’t like the web), and the desktop version.

There are

Answer 4

I’m looking for a job right now, so I can say with confidence that in order to change the color of a button on the front end, you need to thoroughly know the device of the Linux and Windows kernel, the architecture of visual studio, the features of translating intermediate code into machine code, the ENTIRE backend, and fix bugs in parallel on memory management and garbage collection, and if you know all this, you know how and do it, then maybe you will be allowed to change the color of the buttons on the frontend ..... if you want to do more on the frontend, then the general requirements also grow ... ..
