Suggested Approach

Start by clarifying the scope: define 'market size' as the number of Android users or devices in India, and specify whether you're estimating current or potential market. Then use a top-down approach: estimate India's population, segment by age and smartphone adoption, and apply Android's market share. Alternatively, use a bottom-up approach: estimate smartphone sales, replacement cycles, and Android's share of those sales.

Pro tip: Show awareness of India's diversity: rural vs. urban adoption, price-sensitive segments, and the impact of Jio's disruption on data affordability. Also, mention that Android's market share in India is around 95%, but be prepared to justify that with logic (e.g., iOS is premium-priced, limited retail presence).

1. Clarify the question

Ask whether 'market size' refers to number of users, devices, or revenue. Confirm if we're estimating current or future market. Assume current active Android users in India.

2. Estimate total population and smartphone penetration

Start with India's population (~1.4B). Estimate smartphone penetration (e.g., ~50-60% due to feature phone users). This gives total smartphone users.

3. Determine Android's share of smartphones

Use knowledge that Android dominates with ~95% share in India. Apply this to the smartphone user base to get Android users.

4. Sanity check and refine

Cross-check with alternative methods: e.g., annual smartphone sales (~150M), average replacement cycle (3 years), and Android share. Adjust for factors like multiple device ownership or shared devices.

Key Points to Mention

  • India's population and demographic segmentation (age, income, urban/rural)
  • Smartphone penetration rate and growth drivers (cheap data, affordable devices)
  • Android's market share in India (~95%) and reasons (price, OEM diversity, ecosystem)
  • Replacement cycle and its impact on active user base
  • Potential double-counting: users with multiple devices or shared devices
  • Future trends: 5G adoption, Make in India, and competition from iOS in premium segment
