Korean giant LG is launching a new super smartphone has a large display and ready for 4G.

LG Korea has launched a new version in its range of Optimus smartphones. LG Optimus 4G LTE benefits from a touch screen 4.5 inch IPS panel which has a HD resolution of 1280 x 720 pixels. Found under the hood with a 1.50 GHz Qualcomm Snapdragon. This dual-core processor enables the smartphone to support the 4G/LTE. He is accompanied by 1024 MB RAM and 4 GB of flash memory. A microSDHC 16 GB is also provided as a bundle.

The LG Optimus 4G LTE has an 8 megapixel sensor (with LED flash) and a front 1.3 megapixel webcam. Wireless connectivity includes 802.11n and Bluetooth 3.0. This smartphone has a built aGPS module and a battery of 1830 mAh. It measures 132.9 x 67.9 x 10.4 mm and weighs 135 g. LG did not say when he would propose that LG Optimus 4G LTE outside the Korean market. The LU6200 is however a good example of what is the best time.



LG Optimus 4G LTE  Presentation

The LG Optimus 4G LTE is a new generation of cell-screen HD. It does not use the 4G network LTE technology but which also allows large download and upload speeds, but it is important to know that this technology is available at this time than in large cities like Montreal.

Getting Started

Built with seriousness, the casing is made of a plastic hand grips once. The front of LG Optimus 4G LTE  is arbitrary and dressed all in black, even the LG logo is not registered. It’s a shame, because for such a phone, a more daring design would not have been too many. Under this dress, there is little attention. In addition, we are astonished at the lack of an HDMI output, it is difficult to justify a lack, even if the screen is in itself incredible.

It will be well in front of the speaker to hear properly. Our LG Optimus 4G LTE  test model TV reception good waves: it has long maintained the connection in the tunnels of the Metro station Bonaventure in Montreal, but the network has been slow to be located at the exit.

LG Optimus 4G LTE  Screen

4.5-inch IPS panel and a definition of 1280X720, it crushes everything that exists, iPhone 4S and Samsung Galaxy S 2 included. Only the future will offer the Nexus Prime resolution. The colors of LG Optimus 4G LTE  are bright and extremely loyal, while the quality of the image itself is the best we had ever seen on a screen this size.

And as if that were not enough, the touch is perfect precision, flexibility, and responsiveness. We even found a bit more excellent than the iPhone 4S which is however a reference.

LG Optimus 4G LTE  Cameras

The camera on LG Optimus 4G LTE has an 8 MPx sensor,  and it will be essential to a focus before each picture so that it is not blurred. The side of the camera mode, it shows no saccade, but the image noise is important. The camera is not the strong point of the LG Optimus 4G LTE, number of competitors like the iPhone 4S or the Samsung S2 Galaxy are better.

Disk Space on LG Optimus 4G LTE

1GB of memory and 4GB of storage space. We have seen much better, but the SD card slot fills this gap and will accept cards up to 32GB extra.

LG Optimus 4G LTE  Performance

LG has equipped the phone with a dual processor 1.5 GHz heart. Only the HTC Amaze has the same time. This is the most powerful processor that exists today in a phone. Everything is going very fast on LG Optimus 4G LTE, and he never gets tired, even trying to push the limits with multiple applications running simultaneously.

LG Optimus 4G LTE  Battery

Again, we were impressed. With several calls, mobile internet constantly lit, or the sporadic use of GPS, he held two days. With a few phone calls, internet and GPS turned off, you can count on six and a half days. Simply excellent and far ahead of the others, it’s still better than the Galaxy S2, a though reference.

Conclusion on LG Optimus 4G LTE

This phone has two flaws: a very average camera and the lack of an HDMI output. Otherwise, competition is far behind. HD screen, incredible autonomy, or all that power to spare, the LG Optimus 4G LTE is the best on these points. Only the future Prime Nexus Google and Samsung will have similar characteristics in terms of CPU and the definition of the screen.

LG Optimus 4G LTE Root

First of all, I would like to explain what a root does to your LG Optimus 4G LTE. It will create a kind of super-user account in your smartphone’s OS. With this account you will be able to access every corner of the system. Thus, you will have the freedom of uninstalling some applications and widgets which are already preinstalled in your phone. Some of the 3rd party Android applications are not available in Android Market. A root will let you install those kind of applications. Also, some hardware parameters of the phone could be tweaked.

I know that your LG Optimus 4G LTE is running perfectly now. It has a powerful processor and also a lot of RAM memory. But the main advantage is, for the moment, the fact that it is new. After a while, though, you will notice that it will start to run slowly. That happens because you will install a lot of applications and its OS will tend to become overloaded, consuming a lot of its resources. A root on your LG Optimus 4G LTE will solve this problem. Your phone will run like new, again.

I observed another issue with Android OS. Even if, in most of the cases, it is a very stable OS, sometimes it gets blocked. Especially when you run a lot of applications in the background. And those blocks might annoy you after a while. Again, the solution is to root your LG Optimus 4G LTE.

As said before, after you root your LG Optimus 4G LTE you have the opportunity to install applications that are not on the Android Market. You can update to different custom firmwares which come with different features and widgets. Even the CPU of your LG Optimus 4G LTE can be overclocked after your phone is rooted.



A great improvement that a root could bring is the change of the keyboard you use for writing messages and e-mails. You can have the opportunity to install another keyboard, with larger keys, which your fingers could master better.

How to root LG Optimus 4G LTE?

You don’t have to be an expert in order to root your LG Optimus 4G LTE. But you do have to be very careful. The root process, if it is done in an inappropriate manner, may cause serious damages to your smartphone. Therefore I recommend a few things before starting the root tutorial:

– be very patient;

– study a lot what are the risks if the root process fails;

– restart your phone before starting the tutorial and make sure it is fully charged;

– read this post until its end


  1. Universal Root application needs to be downloaded from here
  2. This download must be saved on the memory card of your LG Optimus 4G LTE
  3. Now access the menu of your phone and go to Settings > Applications. “Unknown sources” option must be checked.
  4. Go back in the place you have saved the file downloaded at the step 1 of this root tutorial and run UniversalAmdroot.apk
  5. Wait until the application finishes its process.

Congratulations. Now your LG Optimus 4G LTE root process has ended.

I need to point out again the danger you expose your smartphone if you don’t  follow the recommendations suggested before describing the root process.  Check that the battery is fully loaded and make sure you have restarted your LG Optimus 4G LTE before starting the root process. You need to do those two things in order to ensure that your phone will not crash during the root process. If it will still crash, allow your phone to enter in recover factory settings. Do not restart the root process until the smartphone hasn’t finished the recovery settings procedure.

An extra attention should be given even after the root process has ended successfully. I am referring to the fact that you need to be very careful of the way you are benefiting of the freedom that the root process has given on LG Optimus 4G LTE. Always make sure you know what are the risks for your phone if you install/ uninstall something. Even if you will be able to tweak its hardware settings, please make sure you study a lot on how this will impact your phone working mode. A lot of information regarding the benefits and risks which a root brings on your LG Optimus 4G LTE can be found on XDA Forum.
