India is having a digital revolution since the launch of Reliance Jio. They had launched a phone called as JioPhone [1]. This is powered by KaiOS, hence the market share of KaiOS in India has significantly increased. KaiOS is the second most popular mobile OS in India (ahead of iOS)[3].
JioPhone sold nearly 40 million units in the last quarter[2]! This is a huge market for Google to build apps for as well.
