LG is aggressively marketing its LG G4 flagship smartphone. In June, all the major U.S. carriers were offering freebies like a 32GB microSD card, an additional battery and a charging cradle until June 30.

Now the South Korean giant has a new offer. The latest LG offer allows users to choose from any of the five color options for leather back cover such as blue, red, orange, pink and yellow. Generally, the LG G4 leather back cover is available for $69.

There is a 3,000 mAh second battery available in this offer. Lastly, the deal also includes a battery-charging cradle. Droid Life estimates that all the free accessories available with the LG G4 have a value of about $140.

The promotional offer that began with the launch of LG G4 was first available until June 21. However, later on LG extended the deal till the end of June. Buyers who failed to make the most of the previous deal can now take advantage by sending their submissions to LG by August 14.

The deal is not applicable for refurbished and unlocked LG G4 models, claims Droid Life. In other words, the deal is only available for buyers who are ready to purchase the LG G4 through major carriers of the U.S. and authorized retailers such as Amazon, Best Buy and others.

New customers of LG G4 can submit their documents online as well as by mail. Buyers are required to submit the LG G4 proof of purchase such as a copy of the bill and a photo of the device's box displaying its IMEI number. The deal will expire on July 31.

The LG G4 is the first handset to come with a Snapdragon 808 chipset that features a hexa-core CPU. The SoC is supported by 3GB of RAM. It comes with an improved 5.5 inches Quad HD screen compared to the predecessor model. It also has 32GB of native storage, a 16MP camera with the optical image stabilization feature, an 8MP front-facing camera and a 3,000 mAh removable battery.
