Computer engineering helps to open a smartphone manufactoring unit.

If your goal is to learn how to manufacture Smartphones then as everyone else suggested taking electronics and computer engineering courses is the right choice. On the other hand, if you want to know how smartphones make knowledge like the suggestions you get on your phone from Google now, Facebook, etc., then you need Computer Science courses like machine learning, data mining, artificial intelligence, natural language processing, ....

yes, several cources of CS engineering teach you about programming and several other smartphone manufacturing related topics.

Introduction

Manufacturing has emerged as one of the high growth sectors in India. Prime Minister of India, Mr Narendra Modi, had launched the ‘Make in India’ program to place India on the world map as a manufacturing hub and give global recognition to the Indian economy.

India’s ranking among the world’s 10 largest manufacturing countries has improved by three places to sixth position in 2015#.

The Government of India has set an ambitious target of increasing the contribution of manufacturing output to 25 per cent of Gross Domestic Product (GDP) by 2025, from 16 per cent currently.

Market Size

India’s manufacturing sector has the potential to touch US$ 1 trillion by 2025. There is potential for the sector to account for 25-30 per cent of the country’s GDP and create up to 90 million domestic jobs by 2025. Business conditions in the Indian manufacturing sector continue to remain positive.

Investments

In a major boost to the 'Make in India' initiative, the Make in India week which was held in Mumbai between February 13 and 18, 2016, received an overwhelming response from investors. The fair had closed with INR 15.2 trillion (US$ 225.32 billion) in investment commitments.

With the help of Make in India drive, India is on the path of becoming the hub for hi-tech manufacturing as global giants such as GE, Siemens, HTC, Toshiba, and Boeing have either set up or are in process of setting up manufacturing plants in India, attracted by India's market of more than a billion consumers and increasing purchasing power.

In September 2016, Foreign Direct Investment (FDI) in electronic manufacturing has reached an all-time high of Rs 123,000 crore (US$ 18.36 billion) in 2016, from Rs 11,000 crore (US$ 1.65 billion) in 2014; on the back of enabling policies of the government and its Make in India initiative.

India has become one of the most attractive destinations for investments in the manufacturing sector. Some of the major investments and developments in this sector in the recent past are:

yes i would recommend ,This will help you with the needed knowledge on electronics as well as some exposure to programming. Computer Science or Engineering can help writing the software that sits on the Smartphone but of little help when it comes to Smart phone manufacturing,and definitely its useful one way or the other
