For years, device manufacturers have been exploring ways to beef up device
security while letting users bypass that pesky PIN. Many devices now
feature fingerprint or iris scanners, both of which have proven to be
hackable. Facial recognition could become the new gold standard for device
unlocking, but as smartphone sensors continue to evolve, your phone might
eventually recognize you without scanning you. Instead, it will look for
other unique attributes, such as the tone of your voice, the way you move
or the pattern of your typing.
Augmented reality (AR) has already made a splash in the gaming world, but
future technology of mobile phones could take AR mainstream in industries
including retail, tech support and healthcare. Several mobile device
manufacturers have already released AR toolkits for mobile app development.
The toolkits enable app developers to access a device’s camera and motion
sensors and create apps that lay digital objects on top of the camera’s
live view and move them around with precision.
Macworld recently reported that device manufacturers are also experimenting
with new ways to strengthen the glass used for smartphone screens. Some
wearable devices already use sapphire glass, and researchers are making
significant breakthroughs on self-healing screens and an even more durable
material called graphene glass. This year’s Mobile World Congress is
dedicating an entire exhibition space, called the Graphene Pavilion, to
demonstrations and discussions about how this material could transform the
mobile industry.

Ceullar Service Providers
National: AT&T;, Sprint, T-Mobile and Verizon are the national carriers, often
called the Big Four. They have the most customers and maintain the networks
that tier-two carriers and resellers use. Regional: US Cellular is a
self-sufficient regional network that doesn't cover every city, but it's a
good option if you mostly stay within its network footprint.
Prepaid: The Big Four carriers own Cricket (AT&T;), MetroPCS (T-Mobile), and
Boost Mobile and Virgin Mobile (Sprint). Resellers: Everyone else -- Republic
Wireless, Straight Talk (Tracfone), Ting, GIV Mobile, Google Fi and so on --
leases network capacity from at least one of the Big Four, so you're riding
on their network, either solely or in combination with Wi-Fi.
Carriers have largely done away with two-year contract pricing, but you can
still get it if you want. Or, you could buy your phone outright in a lump sum,
or through monthly installment pricing. As a benefit of this, the dreaded ETFs
(early termination fees) of yesterday are gone -- but you're still on the hook
for paying off the hardware before you switch (see no. 1 above). So, if you
need to be able to switch carriers at a moment's notice, you may want to
scrape together the full retail amount and buy the phone in full. If the new
carrier doesn't work out and you do bolt, keep in mind that you usually get
a 14-day grace period for major problems, like if the phone hardware or
network coverage don't pan out.

Cell Phone Manufacturers
The smartphone marketplace is such a dynamic place that it is hard to keep
track of who's who: just a few years ago, Nokia was at the top, then Samsung
went to rule, and these days, it seems that it's Chinese phone makers that are
aiming to occupy the top 10 list.
Last year, Apple send shockwaves through the industry with record-breaking
sales of its iPhone lineup, and for the first time, it tied with Samsung for
the first place. Naturally, this was not meant to last - and it's natural
because Apple sells only upper-tier phones, while Samsung offers everything
from low- to mid- to high-end devices. In the first quarter of 2015, Samsung
is at the top of the listing again with sales of 82.8 million devices,
grabbing a 24.3% market share, while Apple's 61.6 million sales grant it the
second place with 17.9% of the market in terms of units sold.
The big news following the first quarterof 2015 is that Sony and Microsoft, two
of the most renowned brands, have dropped out of the top 10 phone manufacturers
, replaced by Chinese phone brands. Actually, excluding Apple, the top 10 list
of phone makers now consists of 9 Asian phone makers, and 7 of them are from
China. The newcomer this quarter is Vivo, a phone maker that focuses on
premium handsets with an affinity for higher-fidelity audio capabilities.
