You said "The problem is not the technology - it is the lack of political and financial commitment".
Politicians and money people are not the ones who provide health care, but the health professionals and health workers in the field do.
Thus it may simply be a question of efficient communication, by that I mean the dissemination of existing practical knowledge (textbooks, tutorial videos etc.) to those who need it and can apply it.
We all have probably several old smartphones laying around that could easily be converted to know-how repositories (library-in-a-box or other types of boxed libraries) and given away for free. All it takes is an organization (and funding) that is willing to collect, load and send out these devices to users in LMICs or alternatively provide instructions for uploading such a boxed library and an address to mail to. I for my part (and I am sure many others) would be willing to modify and mail out my old smartphones at my expenses and doing a good deed rather than just throwing them away and jeopardizing the environment.
