How to connect keyboard and mouse to phone?

Question

Keyboard

Hello, the homeless took the computer.
Decided to play pranks - use the phone.
I want to connect keyboard and mouse.
The problem is, there is only one connector...
1. Is it possible to connect a mouse with a headphone jack, will it work, how to implement it?
2. Will it be possible to combine mouse and keyboard cables to connect them to one usb-otg?
Thanks a lot to all who answered! What other ways?

Answer 1

Bought this one .
The problem is only with switching the keyboard to Russian. I didn’t experiment much (only checked the type for the possibility of work). What he had inside - did not make out. It is powered by the device, as I understand it (that is, it will not be able to work and charge).

Answer 2

No way for free. And so buy a keyboard and mouse specifically for the tablet.
