A survey conducted in Vietnam in November 2014 revealed that 67% of smartphone users also own feature phones, with Samsung leading the market at 33% share. Users primarily engage in messaging, web browsing, and taking photos, while brand, pricing, and design significantly influence their purchasing decisions. Additionally, less than 18% of respondents have paid for apps, and most users spend between 50,000 to 100,000 VND monthly on mobile phone usage.
