OPPO is obviously not backing down from its promise to make its new "F" line its photography oriented series. And by photography, so far it has meant selfies. And so it has, as expected, put out the OPPO F1s, which it now bills as the Selfie Expert. Which is a weird claim considering the OPPO F1 Plus announced not too long ago is perhaps a better expert than it. Albeit its expertise does come at a price, literally.
