Not being able to use the iPhone one-handed anymore, has become one of the main complaints of the device. Turns out, there is actually a hidden one-handed keyboard in iOS that nobody is supposed to know about. Developer Steve Troughton-Smith recently found hidden code for a one-handed keyboard in iOS by hacking an iOS Simulator and apparently it has “been there since at least iOS 8.”
They keyboard makes it easier for people with small hands and for people that want to use the phone one-handed. For some strange reason, the feature is hidden in the iOS code and you cannot use it, at least not officially. If you have jailbroken your iPhone, then you can actually activate the keyboard with this tutorial.
