iphone 5s:
The iPhone 5S rumors are heating up. This year's batch includes bigger screen size, wireless charging, improved camera and the possibility of a fingerprint sensor for security.
Bigger Screen Size
To compete with larger phones like the increasingly threatening Samsung Galaxy S3, Apple insiders believe the iPhone 5S will need a screen enhancement. Though Apple CEO Tim Cook maintains the current 4-inch display as optima, the buzz is leaning towards a 4.8-inch Retina Display; the same size as the Samsung Galaxy S3.Wireless Charging
Apple fan boys have been geeking out over wireless charging for the last couple iPhone installments. There may be significant evidence this year may finally be the year. Last month, Apple patented Wireless Power Utilization, a wireless charging system with NFMR, near-field magnetic resonance. Get excited!
12-Megapixel Camera, Enhanced Flash and A7 Processor
The camera and processor seem to be two of the standard upgrades for every new iPhone launch. The next iPhone is believed to come with a 12-megapixel camera, a 4-megapixel upgrade from last year and enhance rear flash capabilities. Following the Apple trend, the iPhone 5S is also likely to bump up to an A7 chip processor to assist with increasingly complex tasks.
Fingerprint Security Sensors
A juicier, more "wow" worthy new iPhone rumor is the possibility of fingerprint sensors for security. Apple recently purchased mobile network security company AuthenTec for $356 million. No surprise where the rumors started, AuthenTec manufactures fingerprint sensors. Does this mean instead of a pass code the iPhone 6 will only unlock to my unique fingerprint?
iPhone 5S, 6 Release Date
Many believe the iPhone 5S could be scheduled for a mid 2013 release, while most maintain a late 2013, early 2014 launch for the iPhone 6.

Samsung Galaxy S4 to feature wireless charging, April 15 launch:

We've known for some time that a new Samsung Galaxy S smartphone has been in the works. Past rumors suggested a possible April 2013 launch date for the Galaxy S4; however, a recent scoop by Samsung-enthusiasts Sammobile indicates a far more precise date of release: April 15. It's likely we'll see an announcement in March at one of Samsung's "Mobile Unpacked" events.

Alongside a supposed shipping date, Sammobile also claims to have more granular details about the Jelly Bean device.

For starters, the Galaxy S4 will sport a high-capacity 2600mAh battery. That's definitely a step up from the S3's 2100mAh pack, giving the S4 a roughly 20 percent advantage over its predecessor in terms of battery power. The new phone is also rumored to feature wireless charging, likely the fruit of Samsung's involvement as a founding member of the A4WP (Alliance for Wireless Power) consortium.

Earlier rumors indicated the S4 would pack a quad-core Cortex-A15 processor, 2GB of system RAM, a 13MP rear camera and a sizeable 5-inch 1080p display. The latest information corroborates most of those specifications, but upgrades the CPU to eight cores with an eight-core Mali-T658 GPU and a Super AMOLED display. The S4 will supposedly ship in white and black.

The smartphone has been known internally as "Project J", but that appears to have changed to "Altius" recently. It's suspected that the Galaxy S4 will actually be branded as the Samsung Galaxy S IV, especially since the company has used roman numerals in the past for the S III and S II.

WOF: What should be the next major development in smartphones?

Smartphones have come a long way since the first PDAs with phone capabilities hit the market. But as the market matures it's getting increasingly difficult for companies to come up with truly revolutionary new features year after year.

Off the top of my head I can think of a few things I'd like to see in the next few years: longer lasting batteries, perfected voice recognition, devices powerful enough for some serious gaming beamed onto the living room TV, and on the carriers' side 'affordable' unlimited mobile broadband.

But what about all the other futuristic things that are promised to us at trade shows? Flexible displays and built in HD projectors? NFC-based mobile payments? Perhaps wearable computing projects like Google Glass will take off and bring the smartphone functions into the fold? In this Weekend Open Forum we want to ask, what do you think will be the next major development in the smartphone world?
