Oppo F5 long-term review

F5 refreshes the page in the web browser on your computer. So what's the Oppo F5, then? Is it a refresh of sorts, too? Or maybe it's a refreshing mid-range smartphone that's trying to look like it's more expensive than it actually is. Refreshing, but not niggle-free. Pretty, but not without its faults. Good in most areas, frustrating in others.
