Oppo calls the F1 a selfie expert phone .display size 5.5 inch quite impressive. It has a resolution of 1920 X 1080 pixels which keeps everything on the screen Sharp. Oppo has a built in eye protection function. Special mention is deserved by the fingerprint scanner on the device. It is one of the fastest we’ve seen on a smartphone so far. In fact the wakeup and unlock function was so fast that we thought that the security lock was not enabled. This phone is so slim handset. I like this phone
