TL;DR
In markets on 2G and unstable 3G, video calls dropped or failed — hurting adoption of a flagship feature. I helped design a low-bandwidth video telephony solution that improved call success by 27% and opened rural markets.
The Problem
In regions like India, Bangladesh, and parts of Africa, many users were on 2G or unstable 3G. Video calls frequently dropped or never connected, creating frustration and holding back adoption of what was meant to be a flagship capability.
The Approach
I worked with engineering to design for graceful degradation rather than failure — optimizing codecs and building fallback options so that when bandwidth dropped, the call continued at lower quality instead of dropping entirely. I treated real-world network conditions, not lab benchmarks, as the bar to clear.
The Solution
I helped test the solution across different rural environments to validate it under genuine field conditions, tuning the fallback behavior so the experience stayed usable on the worst connections members actually had.
The Impact
Call success rates improved by 27% in low-bandwidth regions, and the work made Samsung devices meaningfully more appealing in rural markets — with adoption forecast to grow ~15% across five countries. It's also where my conviction took root that good telehealth and consumer tech must reach from big cities to the most remote, disaster-prone corners of the world.
