The devices that made history: fingerprint, water resistant, and other smartphone pioneers

Some of you may have expected another phone to star in this category, but no, it turns out that the Toshiba Portégé G500 can be regarded as the first smartphone to come with a swipe-based fingerprint scanner. This 2007 slider was running on Windows Mobile Standard 5.0, came with a single-core, 416MHz Marvell processor, 64MB of RAM, and a 2MP camera at the back.

Fingerprint scanner (touch) - Apple iPhone 5s

Although it was definitely not the first handset to come with a fingerprint scanner on board, the iPhone 5s was the first to employ a touch-based one. Such sensors have proved to be a bit more popular and having a smaller margin for error, hinting us that we will be seeing them on more and more phones in the future.

Xenon flash - Nokia N82

Although it's not the first phone to come with a Xenon flash (the title goes to Sony Ericsson and some of its top mid-2000 devices like the K800), the first smartphone to come with a xenon flash was the Nokia N82, a noteworthy Symbian-powered Nokia device with Carl Zeiss optics and red assistance light that aids the auto-focus in low-light situations.

3D camera - HTC Evo 3D

Although it proved to be a gimmick and ultimately a flop, this HTC device allowed users to capture three-dimensional images thanks to the dual-camera setup at the back of the device. Yes, it was not the first smartphone to allow you to shoot 3D images, but it was the first globally-released one to enable both 3D image capture and 3D output via HDMI. Despite the novelties it brought to the smartphone scene, it turned out that 3D was not ripe for market success yet. 

Water resistance - Nokia 5500 Sport

Smartphone OS? Check! The Symbian (9.1) S60 3rd Edition OS on board made sure that this handset is smarter than the regular feature phones that it shared design cues with. Since it was rugged, it was also not afraid of casually taking a dip in the water. The hardware specs of this Nokia device were otherwise pretty in line with what the hardware specs that were mostly prevalent at the time - a 208x208 pixel display, a single-core ARM9 processor, and 64MB 
 

microSD card slot - Motorola A1000 Communicator

The first device that classifies as a smartphone and allowed its owner to put a microSD card inside was released all the way back in 2004 and was made by Motorola. The A1000 Communicator had merely 24MB of native storage, but you could enjoy up to 1GB of additional storage on this Symbian OS 7.0 handset - reportedly, 2GB microSD cards did not work with well.
