iOS 10.3 Has a Hidden CheckerBoard Diagnostics Mode Setting - Accessing is Pretty Straightforward too

With the release of iOS 10.3 Beta, Apple has baked in a new CheckerBoard diagnostics mode, allowing Apple to quickly go through certain parameters of your iPhone or iPad. Using this feature, the company can find out if there is something wrong with the software or hardware, or maybe both. Interestingly, anyone can access this feature, thanks to developer Steve Troughton-Smith. But remember, while this feature is accessible right now by anyone, there's a chance Apple might lock it down as soon as the final version of the software is released to the public later on. Also, since this feature is meant for Apple and its employees to run diagnostics on your iPhone or iPad, therefore please do not tinker around with it too much. There's no telling what sort of damage you might end up doing to your device. Therefore it's best to play safe at every step of the way.

And like I mentioned above, there's a high chance Apple might even end up removing this feature altogether in the final release in a way that it's only left to be accessed by the company's employees only. Nonetheless, it's a cool little party trick to know about, given you are running iOS 10.3 Beta.
