Root LG Optimus L3 E400 with Easy One Click Tutorial

LG Optimus L3 E400 is a low-end device, which is directly competing with Samsung Galaxy Y phones.

The L3 device can be rooted now. Though, it could not make a significant dent in the market share of Galaxy Y due to the extreme popularity of Samsung phones at present, LG has its own loyal share of followers. I do wonder at times why  they were not able to achieve the heights they desired in the cellphone market.

As per the persons in our team who have reviewed the device,the phone is a package of stylish looks and has a good enough battery backup though it was found to be lacking on clarity and highly sensitive sensors, which is some thing most users look for. The L3 can compete with Samsung Galaxy Y Duos or Samsung Galaxy Ace Duos.

The 3.2-inch LCD TFT capacitive screen is big enough to watch things on the screen. Further, 320x240pixels image resolution with 256 colors and 125 ppi density makes this phone a real treat for the eyes. The phone can be upgraded to latest Android 4.0 ICS Operating system, which is another good option.

If you have already purchased this phone and want to install unlimited Custom ROMs or want to install any of the Android Apps, go ahead and root your device using this simple tutorial.
