6. One Plus 3
While the first two One Plus models featured LCD, the company decided to give it a try and go with OLED. They didn’t make a mistake. One Plus 3 has a screen of 5.5 inches with 1080 x 1920 pixels and ~401 PPI pixel density. The screen is praised for the great viewing angles and less reduction in brightness. The only issue may be that the colors don’t seem natural. The rest of the phone is great as well, delivering 6GB of RAM, 64GB of storage, Quad – core processor and a praised back camera of 16MP.
