HTC One 'Duo Camera' explained

The successor to the HTC One is rumored to come with two cameras. Now, there might be some explanation on how those cameras will be put to use in the new phone.

The folks over at mobile-industry tracker GSM Arena discovered on Tuesday a leaked ad for the upcoming HTC One from Australian carrier Telstra. That ad shows the same handset featured in countless leaked images and reveals details on the device's "Duo Camera."

The feature follows what other major handset makers have delivered in their devices this year, including Samsung, Sony, and LG. Those companies' flagship handsets feature one camera that takes rapid shots. After the shots are taken, users can decide what parts should be blurred and what should be clear. They can also pick the version they like best. With two cameras on board, the HTC One could conceivably enhance those features, since it's using two cameras to snap photos rather than one.According to the ad, the Duo Camera uses the handset's two cameras to: "Create vivid images even in low light and professionally edit memories after you've taken the shot. Choose where to focus, highlight what you love, soften backgrounds and add 3D effects."

The ad also highlights the new HTC One's BoomSound capability and a 5-inch full HD "scratch resistant" screen.

For its part, HTC hasn't confirmed any features in its upcoming HTC One, but the company plans to unveil the phone on March 25.

2014 Huawei unveils new 4G LTE-connected devices at MWC

Chinese wireless device maker Huawei unveiled five new 4G LTE devices at the Mobile World Congress 2014 tradeshow in Barcelona on Sunday.

The company, which now claims to have ranked third in terms of worldwide smartphone shipments in 2013, is trying to make waves with its new products. These products include two small tablets, a new smartphone, the "world's fastest" MiFi, and a new Net-connected watch/fitness tracker.

With its two new tablets, Huawei has blurred the lines between smartphone and tablet. The slim 7-inch Huawei MediaPad X1 could be seen as more a "phablet" than a tablet. It comes with a SIM card slot that provides 4G LTE data connectivity as well as allows users to make phone calls and send SMS text messages.

The device also sports a 1.6GHz quad-core processor and a full HD display, making it a great device for viewing streaming and digital content. The MediaPad X1 will be available in stores in the UK later this year.

Like the Media Pad X1, the MediaTab M1 could also be used as an oversized smartphone. The 8-inch Android tablet has a SIM card slot, 4G LTE support and also allows users to make phone calls and send and receive SMS text messages. It has a 1,280x920-pixel resolution screen and comes with a 1.6GHz quad-core processor. It runs the older Android 4.2.2 Jelly Bean operating system.

In addition to the, the new tablets, Huawei also announced a new 4G LTE smartphone, theAscend G6 4G. A highlight of the new smartphone is the 5-megapixel front-facing camera, to offer better quality selfies. The 4.5-inch phone has a 960x540-pixel resolution screen, and it comes with a 1.2GHz quad-core processor. The device runes Android 4.3 Jelly Bean and sports an 8-megapixel camera on the back.

Pricing and availability information were not disclosed at the press conference.

Huawei also announced what it's calling the world's fastest MiFi, the Huawei E5786. The device connects to carrier LTE networks and will provide download speeds of 300 Mbps, the company said. Upload speeds top out at 100Mbps. The MiFI supports Wi-Fi 802.11a/b/g/n and 802.11ac, and it can connect up to 10 devices to the carrier LTE network via Wi-Fi. It has a 3000mAh battery that supposedly offers up to 10 hours of use. And it also allows users to charge other devices connected to the MiFi. So if your tablet or smartphone is running low on battery, you can plug it into the MiFi and get a charge.

The Huawei E5786 will be available the second half of this year.

Huawei joined the wearable device party with the new TalkBand B1, which is a Bluetooth headband and fitness tracker in one.

The new device will cost 99 euros. It uses both Bluetooth and NFC or near field communications for connectivity. The Talkband can pop out of the wristband and be used to make a call. And then it can be popped back in. It's also water and dust resistant. It tracks sleep patterns and other health vitals. And the strap itself is a USB connector, which lets you charge it up easily. It has seven hours of talk time and two weeks standby capability. The 1.4 inch OLED screen is not a touch screen, so the device is managed using an app on a smartphone.
