LG may be planning to take on Samsung at the Mobile World Congress (MWC) 2016 with a latest refresh of its G series, if a new set of rumours is to be believed. The two Korean handset manufacturers have plans to launch their next flagship devices at the largest mobile expo in the world in Barcelona. The MWC 2016 is scheduled from Feb. 22 to 25 in Spain.

As reported by Korea Times, an executive at LG confirmed that the company will officially unveil the G5 smartphone at a press conference a day before the opening ceremony of the MWC 2016. Last year, LG is said to intentionally miss out the event where Samsung announced its most coveted Galaxy S6 series.

The flagship is expected to arrive with a full metal unibody design and sport a 5.6-inch QHD display with Gorilla Glass 4 , reports GSM Arena. True HD IPS display with a 3840 x 2160 resolution (4K) and flexible touchscreen.

Earlier reports say that G5 could be the most secure smartphone ever. LG has reportedly teamed up with IRIENCE , a South Korean-based company specialising in eye-scanning technology, to develop an iris scanning technology. LG may replace the biometric fingerprint sensor with the iris recognition technology or keep both features for the G5.

The latest Snapdragon 820 chipset will be fueling the LG G5 coupled with 4GB of RAM. However, there are rumours that the device may house up to 6GB of RAM, reports Know Your Mobile. The LG G5 will reportedly come in three internal storage options of 32GB, 64GB and 128GB with probably a microSD card slot.

The most noteworthy feature that LG G5 may tout is a removable battery compartment to grab the limelight from Samsung. The bottom bezel of the handset will open like a drawer for replacing the battery unit. Most of the smartphones launched with all-metal unibody design generally do not house a removable battery.

The top-end device by LG is slated to be equipped with LG’s own mobile payment system G Pay. This will allow users to make in-store payments through their mobile handsets. The device is speculated to come packed with a humongous 4,000 mAh battery.

Finally, the LG G5 is expected to feature a 20-megapixel main camera with a 1.2-inch Sony sensor, laser autofocus and optical image stabilisation (OIS). The front-facing camera will host the rumoured iris scanning technology for advanced security.
