Product Review: Lg Optimus 4x Hd

The low-priced entry into the smart phone superclass
With light prejudices, I took the opportunity to take LG’s new top-class smart phone under the microscope. After the predecessor (the LG Optimus 2X) has a rather bad impression with me and many other customers, I was really curious how LG would like to go back straight. So far ahead: Between the LG Optimus 4X HD and the LG Optimus 2X are worlds-very positive worlds. For the summary simply runterscrollen. There is a 5-minute video, which summarizes the most important features.

The technical data are excellent. So the LG Optimus 4x HD does not have to hide from its competitors (the Samsung Galaxy S3 and the HTC One X). In order to record the performance once, the following are the main benchmarks.

SIM card

Unlike many other current smartphones, you do not need to get a Micro-SIM. You can insert your “normal” SIM card into this smartphone.


No special surprises await you. As usual, you’ll find a power supply, a pair of headphones and, of course, a manual. But… what is the… sticker? Well, indirectly already. More specifically, these are so-called NFC tags. A very cool thing! But more about this later.


The design is known as taste. I personally like the Optimus 4x HD purely optically good. It is very simple. The front consists for the most part from the display and there are only 3 more hardware keys:

– An on/off switch
– A volume rocker

That was it. Android’s typical menu buttons are part of the capacitive touch screen.

Sideways around the smartphone is a chrome-like bar. This looks noble, but is slightly slippery. Nevertheless, the mobile phone will not slip out of your fingers, because the back of the case is made of corrugated plastic with a rubberized coating. Purely optical is not a highlight, but the smartphone is really great in the hand. Yes okay… it mostly consists of pure plastic. Many do not like this, hence the often derogatory term “Plastikbomber”. This is not the case with most of the competition products but I have to say that the Optimus does not really feel cheap. Here are a few pictures, including a size comparison with the Samsung Galaxy S2 and the HTC One X.


Who actually says that a device, which consists to a large part of plastic, can not be worth. I, for my part, find no defects in the processing. Nothing wobbles or crunches. The back of the case is very thin (comparable to that of the Samsung Galaxy S2), very bendable and is easy to remove from the smartphone and turn it on again. Once pressed on, she sits bomb-proof.


The display, with a size of 4.7 inches, is a simply huge. Such a large display brings some advantages with it, but unfortunately, unfortunately, the disadvantage that operation with only one hand is difficult. The screen itself makes a very good impression. Thanks to the HD resolution (1,280 x 720 pixels) everything looks very sharp and with a maximum luminance of 650 candelas per square meter is also easy to read under the sun. Only colors in the test are not quite as good as some competitors with AMOLED display. In addition, the black level of the Optimus 4X HD could be better. Nevertheless, I am convinced by the very good, bright and crisp display. It is also worth mentioning that the screen is protected by gorilla glass.

battery pack

The LG Optimus 4X HD comes with a fairly large 2150 mAh battery therefore. Nevertheless, under normal circumstances the duration is rather average. A large display and a powerful CPU need a lot of energy. A normal working day, however, the smartphone also with the highest display settings easily. If you are satisfied with a lower display brightness (I often use the automatic setting) and use the energy saving mode, you can also have up to two days of fun with this smartphone without having to visit an outlet. Furthermore, I judge it positively that there is no fixed battery, but a replaceable.
If you are particularly interested in a long-lasting battery life, you should take a look at theMotorola Razr Maxx .

Multimedia: camera, speakers

The LG Optimus 4X HD is equipped with an 8 megapixel camera, as well as with a 1.2 megapixel front camera. The camera is sufficient for snapshots. For more but probably not.At first, there were strong problems with the autofocus. This set up briefly however … rejected the attitude but usually again, before the trigger could be actuated. After I have installed a software update in the meantime (very praiseworthy LG), this problem could be improved somewhat, but the camera remains rather average. With very good light conditions and with a bit of luck, really good pictures can succeed, but unfortunately this is not the rule.Especially in bad light conditions I would rather the pictures with a “satisfying”.
The cameras of the competitors (HTC One X or Samsung Galaxy S3) can score with better pictures. This also applies to the trip time. Unfortunately, this is also above the competition.Apart from the camera quality there are the usual functions in the camera app (panorama, series recording and co).

Worth mentioning would be the time-catch recording mode. If this mode is activated, immediately before you take the shutter will make some shots. After you press the shutter button, you will see 5 images. From these you can choose your favorites.

Positively, I must highlight the recorded videos. Videos takes the Optimus 4X HD with a full-HD resolution of 1920×1080 pixels. The videos can score through a good screen. The video app comes with a few special features therefore. So you can zoom in the picture, while a video is currently running. If you’re looking for a specific spot within the video, you will not have to scroll around and rewind indiscriminately, but you can have a small preview image displayed, making it easier to find the desired spot.

The loudspeaker I would call as “average”. It is not superior, but not much worse than the competitors. It is still a smartphone. For navigation purposes or for the one or the other video absolutely sufficient. However, if you often listen to music with your smartphone, you should be better off to listen to headphones.

Software: Operation, Quick Memo, NFC

The LG Optimus 4X HD is currently running Android 4.0.3 (Ice Cream Sandwich). Whether an update to the latest Android version is planned, is currently not known at this time.However, the device is also convincing with ICS. The operation is consistently fluid and goes without rucker or crashes. In addition, LG, like most other manufacturers, also has its own surface tinkered. The so-called “Optimus UI 3.0” is surprisingly really great. In contrast to many other manufacturers, this surface hardly intervenes in the optical design of Ice Cream Sandwhich. In a purely optical fashion, ICS was only slightly revised. The may be taste… the one or the other finds TouchWiz or HTC Sense perhaps quite appealing… others like the standard design of Android for it very much.

Not only the look was changed slightly, but also the functionality. So the status bar can be modified, the transition type of the homescreens can be adjusted and the lock screen can be easily modified. All in all a very successful surface, which gets me some plus points.

Also, I liked LG’s Quick Memo feature. With this function (can be started from the status bar), you can write a note on your screen and save or send it quickly. Nothing breaks, but still practical.

Let’s get to the NFC tags. You can use a preinstalled app to create user profiles that will be activated when the smartphone comes into contact with one of the stickers. For example, you can create the “Nighttime” profile. You put (sticks) one of the included stickers on your night table and tells the app to switch your smartphone into silent mode and start the alarm app as soon as the smartphone gets contact with this sticker. If you now go to bed in the evening and put your smartphone on your night table, this profile is activated. A really very practical thing. There are 2 stickers included and you can buy further. For example, profiles for the car (activate GPS, start MP3 player) or for the office (activate silent mode, start the app).


On the whole I am quite impressed by LG’s new smartphone. Where the predecessor still had weaknesses, the Optimus 4X HD can score points. It is technically on a par with other high-end smartphones and also comes with a neat surface therefore. The processing is flawless and also the display is probably among the best, which one can currently find in the market. The design may be a taste, but the device is very good in the hand can not be denied. Speakers and the operating time are rather average. The camera, however, can not keep up with those of other top models. Now comes a special point: The price! With only 459 € is the LG Optimus 4X HD namely currently 40 € cheaper than a HTC One X and even 69 € cheaper than the Samsung Galaxy S3 . So if you can easily live with light smears on the camera, this is really a secret tip, as far as the price/performance ratio is concerned.
