India proposes requiring smartphone makers to share their source codes with the government and make several software changes as part of a raft of security measures, prompting behind-the-scenes opposition from giants such as Apple and Samsung.

The tech companies have countered that the package of 83 security standards, which would also include a requirement to alert the government to major software updates, lacks ​any global precedent and risks revealing proprietary details, according to four people familiar with the discussions and a review of confidential government ‍and industry ⁠documents.

The plan is part of Prime Minister Narendra Modi’s efforts to boost security of user data as ‍online fraud and data breaches increase in the world’s second-largest smartphone market, with nearly 750 million phones.
