Currently I'm using a Oppo F5 phone which I think is a great smartphone and Yes it does what I expect. I can almost say that I had the best deal and decision when I purchased this device. I stumble upon a post where I figured out that my Oppo actually can be traced using another Oppo and this feature can only be enabled if you altered some settings in the Developer Mode option. How about you? what is the best secret feature of your phone?
