It's Lynn La from CNET here at Mobile World Congress in Barcelona, Spain with the LG F Series.
The F Series is LG's line of 4G phones, and both of them run on Android Jelly Bean.
The F7 has a 4.7-inch screen and is powered by a 1.5 dual-core processor.
On the back, there's an 8-megapixel camera and on the front is a 1.3-megapixel camera.
It's powered by a 2.54 ampere-hour battery.
Now the smaller model is the LG
Optimus F5 with a 4.3-inch screen.
The F5 is powered by a 1.2 dual-core processor and it comes with 8 gigs of onboard memory, and on the back there's a 5-megapixel camera.
For front-face shooting, there's a 1.3-megapixel camera.
The Optimus F5 will be released in Europe in the 2nd quarter with the F7 following afterward.
Again, I'm Lynn and this has been the LG Optimus F Series.
