"OnePlus hasn’t been making Android phones for a very long time, but over its four years in existence it has made numerous screw ups. This all finally led up to last week’s massive credit card breach. It’s time we stop trusting a company with such clearly low standards.
Who Is OnePlus?
Founded just a hair over four years ago—at the end of 2013—OnePlus is a subsidiary of Chinese electronics manufacturer Oppo. The initial idea for the company was admirable: to make smartphones with high end components and features without the high end price tag. That’s something we can all get behind, and OnePlus was received with much fanfare in the Android community."
