Andriod/Ios Keyboard and Mouse Support

I have been play minecraft on my pc but it resently broke down, so I am playing minecraft on my phone and idk if ios has this but when i connected my keyboard and mouse to my phone, I could not play normally like I do on my pc, so I had to get the tool box for mcpe but this lagged my game alot, so in conclution I would like there to be keyboard and mouse support for andriod/ios (If ios does not have keyboard and mouse support
