What I've tried - both devices connected to same WiFi network (I checked the ip address assigned to the Android device by the router in its Wifi Settings); I also checked the router 'dashboard' (the settings you're able to change just by accessing its local ip address) - in Termux - execute whoami and passwd beforehand - see if anything came up in logcat -s 'sshd:*' while connecting (but nothing was outputted for some reason)

Solution:

you'll need to connect to different port

sshd -p 8022

sshd -p 8022

and then on your raspberry pi, connect to it on port 8022...

Thanks, didn't realise for sshd it was as simple as using the '-p' option (identical to ssh) since there wasn't an example of it here: https://wiki.termux.com/wiki/Remote_Access, so I missed that 'test'
