Optimus G Pro vs Galaxy S IV

It was only very recently that LG announced its upcoming flagship, Optimus G Pro. The feature-rich smartphone will be LG’s most advanced to date. We know about Optimus G which was released last year to rave reviews. It is regarded to be one of the best smartphones in the industry today. LG Optimus G hardware powers Google Nexus 4 as well. This is the first time Google has partnered with LG. In the same market, the toughest competitor LG is going to have is Samsung. Galaxy S series phones are extremely popular. They are so popular that at one time, they overtook iPhones in sales.

Let’s take a look at the technical aspects of LG Optimus G Pro and Samsung Galaxy S IV (which will be unveiled next month) and compare them.

Comparing Technical Specifications

LG released the tech specs of G Pro two days ago, and it promises to be one of the most powerful smartphones out there. Here is a comparison between the hardware features of Galaxy S IV and Optimus G Pro.

As you can see, both the phones are power-packed. The major differences are in the display size, technology, and dimension; and in the processor used.

The display on G Pro is obviously larger. It uses a slightly different kind of technology than Samsung’s Galaxy S IV. Samsung’s own pioneered AMOLED display technology is one of the very best high-contrast displays available in the market today. It can be seen on only a few of the other devices. Some of them include the older Nokia Lumia 900, Galaxy Nexus, etc.

Super AMOLED and its variants have been very important in the success of Samsung phones. Since Samsung is the only company with some level of infrastructure to manufacture AMOLED screens, they are shipping almost all of their phones with it. Samsung doesn’t have the infrastructure to make AMOLED panels for other manufacturers, and that is why Nokia had to switch to LCD IPS panel for Lumia 920.

On the other hand, Optimus G Pro uses Super LCD IPS, which is found on most of the other devices including Apple iPhone. Here is an article about the difference between AMOLED and LCD.

The Processor used in these devices are ultra high end. Qualcomm’s Snapdragon series has been benchmarked to be one of the fastest processors available in the market. Snapdragon uses specialized processor design known as Krait, which is based on ARM v7 instruction set. It is different from ARM Cortex cores found in the other processors in the industry—Samsung Exynos, TI OMAP, NVidia Tegra, etc.

It is not yet known, though, how Exynos A-15 chip will perform against Snapdragon 600. These are the first ever devices to run these processors.

Another important aspect of these devices is the build quality. Samsung phones have not been quite great in terms of build quality, due to their use of cheap plastic and removable batteries. LG Optimus G had a unibody design that was reinforced at the back with Kevlar and Gorilla Glass. With Optimus G Pro, we will be getting a removable battery. However, LG is much better than Samsung in build quality.

On other aspects, these smartphones are pretty much identical. It is hard to make a decision as to which to choose.


If you are interested about a large display panel, without doubt LG Optimus G Pro is your choice. Also, based on past experience, Snapdragon 600 is expected to be better performing than Exynos. That is one more point in favor of LG. Also, if you looked closer, you would notice the battery is also larger in the LG phone.

On the other hand, the camera of Galaxy phones has been quite brilliant and better than LG’s. LG Optimus G’s camera did not receive big reviews. Also, Galaxy S series phones are known to be true performers and are very popular.
