My first Oppo and probably last. Doesn't have always on screen display but the most annoying is the Apps that misbehave. I'll be using an app, including SMS and it closes. Never had a phone do this before. Camera is below average. Portrait is better than photo with less reflection in eyes.. Night pics are washed out. Fingerprint technology is good. Colour on screen is good speaker down the bottom is loud but not Stero?
