This is a problem of extraordinary implications, requiring immediate attention, thank you for posting this Abishek.
I think creation of easier mechanism (like contact free door-to-door pick-up and delivery) for the donation of smartphones, computers from cities to rural areas can help reduce the pain for several children immediately.
I have found links to few Govt. and NGOs working on donating electronic devices for education,
Pune's Zilla Parishad (Govt.) which has tremendous track record for improving rural living conditions has started a donation program - https://www.thehindu.com/news/cities/mumbai/donate-smartphones-laptops-to-help-poor-students/article31997654.ece .
Used phone selling service - Cashify has put up a donation portal for customers to donate their smartphones - https://www.cashify.in/donate-for-education .
Another such, used phone selling platform - budli claims to donate a portion of every transaction to NGOs - https://budli.in/budli-charity (They seem to be doing this even before COVID-19).
Xiaomi seems to have partnered with Teach for India (NGO) - https://www.livemint.com/companies/news/xiaomi-joins-teach-for-india-to-donate-smartphones-worth-2-crore-11597306454757.html .
