BKAV calls Bphone the first designed- and made-in-Vietnam phone. Other Vietnamese companies have put their own brands on Chinese-made designs, but BKAV spent $20 million and four years building Bphone.
Pricing for Bphone ranges from about $458 to $925. Most people in Vietnam make less than $150 a month, but there is a market for pricey phones. Nearly half of all smartphone sold in Vietnam come from Apple and Samsung, according to market tracker Strategy Analytics.
BKAV created its own software -- called the Bphone Operating System, or BOS for short --- to layer on top of Google's Android software. BOS comes packed with many BKAV-designed apps, including a browser (Bhrome) and dialer/Internet-based calling app (Btalk). Another key feature of BOS -- strong antivirus software, which is BKAV’s bread and butter.
