What the iPhone 7 needs to stay ahead of Android

Apple is expected to unveil the iPhone 7 in a couple of months, and the rumor mill is already churning out new guesses and "exclusives" from "sources" on a daily basis.

Rather than endlessly debate whether Apple will or won't remove the headphone jack, let's look at where Apple is lagging behind flagship Android handset maker Samsung, and what features it needs to add in order to keep up.

A new and unique gimmick
It really could do with something to set it apart from the rest.
Waterproofing
It seems to come as a bit of a surprise to Apple that people want to take their iPhones into the outdoors, where it sometimes rains.
Please Apple, can we have an iPhone that is waterproof? Samsung has it, and while it might not be perfect, it's better than nothing.
Will we see this? We're seeing signs that Apple will beef up the waterproofing of the iPhone 7, but it seems unlikely that we'll see an IP68 rated device such as Samsung's Galaxy S7.
Shatterproof screen
There's no doubt that Gorilla Glass is tough, but as the name suggests, it's still glass. And glass has a habit of shattering.
A sapphire display would be awesome, but a tough display such as that fitted to the Motorola Droid Turbo 2 would do fine.
Will we see this? Outlook doesn't look good.
Drop the 16-gigabyte storage option
Apple used the 16GB of storage as a way to upsell a more expensive iPhone, and it is a trick that has worked in the past. 16 gigabytes of storage just isn't enough these days, and it no longer makes sense for Apple to continue to offer it since it creates so much user dissatisfaction.
Will we see this? Almost certainly.
