At this rate its safe to bet eating your hat, that at least the 4.7 inch iPhone, will have a vastly superior display cover to anything that has come before it. Sonny Dickson and Marques Brownlee has confirmed the iPhone 6 display cover as being super durable and high quality, and likely made of sapphire crystal.
By now you've likely seen or heard of ONEPLUS, and their "flagship killer" the ONE. If specs were the only thing that mattered, there would be no good argument not to get this phone. The larger capacity ONE brandishes:
5.5inch 1080p 401ppi display, 2.5Ghz quad-core Snapdragon 801 processor, 3Gb of LP-DDR3 RAM, 64Gb of storage, and CyanogenMod 11S OS over Android 4.4.
And none of those is its best spec. Click the link below to learn what the best spec is for OnePlus' self proclaimed "flagship killer."
