If you *really* had to, how much of your job could you do on your phone?

I am anticipating some time over the coming weeks without access to my laptop, and am wondering if I can continue to make even a part-time contribution during this time. My stack would look like:

• Email and slack as normal
• Hop on customer calls
• It sounds like hell, but I bet i could set up an SSH client on my phone and software develop on the repos on my laptop from it. (Anyone tried this?) Github app + Asana app means I can still do stuff like formal PRs
• Ops tools like moving customer funds is doable from mobile, but the internal tools are definitely not intended for mobile devices

Alternatively, if I can't code on my phone, maybe I can at least thoroughly pseudo-code and send that to colleagues to let them translate to proper code? Sounds like it'd just annoy others and slow them down though.
