LG G3 vs Samsung Galaxy S5: an in-depth look

by: Joshua VergaraJune 24, 2014

The latest 2014 flagship smartphones from all major Android OEMs are now available, and it’s always interesting to see how they fare against each other. Every flagship may have some key features in common, but also manage to offer something unique, be it the full metal design of the HTC One M8, or the fingerprint scanner and heart rate monitor of the Samsung Galaxy S5.

The LG G3 was the last smartphone to make it out of the gate, but does it offer enough to take the lead over some stiff competition? In the first of many comparisons to come, today, we’ll be taking a look at the LG G3 against the Samsung Galaxy S5!

When it comes to design, both of these smartphones tried to offer something that would stand out with their overall material choices. But as we now know, both Samsung and LG managed to bring something different to the table, without straying too far from their past iterations.

The Samsung Galaxy S5 mostly retains its look from previous generations, with an angular look with rounded corners, which has more or less become a signature look for Samsung smartphones. What is now different is a back cover that is made from a perforated, or dimpled, plastic material. Unfortunately, this change did not receive the best welcome. While many appreciated the move away from glossy plastic, some considered it a step down from the faux leather rear cover that was first introduced with the Samsung Galaxy Note 3.

LG seems to have a grasp on the negativity toward glossy plastic as well, and moved to a harder polycarbonate that was treated to have a brushed feel. Granted, LG did have our hopes up with regards a metal body, but this change was still quite appreciated. The LG G3 definitely has an attractive exterior that arguably moved in a more stylish direction compared to the Samsung Galaxy S5.

The Samsung Galaxy S5 retains the same button layout that we’re all used to, with the tactile home button flanked by a capacitive back key, and, this time, a Recent Apps key. The power button and the volume rocker are found on the right and left sides respectively. On the other hand,  the unorthodox button layout of the LG G3 definitely takes some getting used to, with the latest flagship featuring a more refined version of the rear buttons that were first introduced with its predecessor. Having to access the buttons placed at the back of the phone does begin to feel very natural after some time.

While the Samsung Galaxy S5 features a 5.1-inch display, up by 0.1-inch from the Galaxy S4, the screen of the LG G3 grew a whole half inch diagonally over its predecessor, to 5.5-inches. This might have meant a huge difference in the size and resulting handling experience, but that isn’t the case this time. Courtesy of its ultra-thin bezels, the LG G3 doesn’t outsize the Galaxy S5 by more than a few millimeters on any side. The result is a great handling experience on the LG G3, a phone that is barely harder to manoeuvre than the Galaxy S5. If you are a  stickler for one-handed usage, the Galaxy S5 will probably be better for you, but not by much.

As mentioned, the reason for this compact design of LG’s flagship is the very thin bezels all around, allowing for a maximized screen real estate. On the other hand, the Galaxy S5 grew its bezels out a little more, likely as an accommodation for its IP67 certification, which is certainly a small price to pay in exchange for the protection against and dust and water.

Overall, while we do enjoy the evolution of design of the LG G3 quite a bit more, its shortcomings in the resistance department makes it the more fragile device of the two. Nonetheless, we tip the hat to LG for managing to pack a larger screen into its device, without making the handling experience that much different than that of the Samsung flagship.

Display technology might be hotly debated here, as the IPS performer on the LG G3 has been blown up quite a bit, while the AMOLED tech of the Galaxy S5 continues to please.

lg g3 vs samsung galaxy s5 aa (25 of 35)

High saturation is the name of the game when it comes to the Galaxy S5, with colors that really pop out. Sharpness and viewing angles are fantastic on this screen that comes with a 1080p resolution, resulting in a pixel density of 432 ppi. When compared to the bigger LG G3 screen, we don’t see the Galaxy S5 display really losing too much ground, but the display of the LG device is definitely a sight to behold.

lg g3 vs samsung galaxy s5 aa (16 of 35)

A pretty massive increase to a resolution of 2560×1440 resolution results in a pixel density of 534 ppi, which is noticeable when compared to the 1080p competitor, albeit not by too much.Viewing text on this display is a breeze, and media viewing does get a boost with the larger screen, making both games and video enjoyable across the board. While its viewing angles might suffer a bit and its colours take on a warmer tone, the takeaway is that the G3’s large display is very enjoyable.

That said, if you’re looking for punchier colours and don’t need the higher resolution, you can have a great time with the Samsung Galaxy S5. We just have to give LG a lot of credit for doing a really good job with their first Quad HD display.

lg g3 vs samsung galaxy s5 aa (35 of 35)

With regards to performance, there is little to differentiate between the two smartphones, as both sport a quad-core Qualcomm Snapdragon 801 processor, clocked at 2.5GHz, backed by the Adreno 330. Both the Samsung Galaxy S5 and the 16GB variant of the LG G3 come with 2GB of RAM, but you get the extra boost of 3 gigs of RAM if you pick up the 32GB version of the latter.

Work and play are ultimately as easy as they can get on these two flagships, as either one will perform exactly the way you need them to. Users who tend to harp on lag won’t find any that will truly hinder their experience, but it is worth noting that both operating systems can suffer from some architectural issues that can be perceived as lag. This is of course not due to any shortcomings on the part of the processing packages, but rather the way the user interfaces loads are structured. Good examples of this issue are the Recent Apps screen on the LG G3 and MyMagazine loading every article at once on the Samsung Galaxy S5.

Ultimately though, speed is in no shortage here, and you’ll get everything you need done easily, with either smartphone.

lg g3 vs samsung galaxy s5 aa (15 of 35)

There’s also no shortage when it comes to hardware offerings, though Samsung continues to try and pack in more than the competition, even if the usefulness of these extras always comes into question. With both smartphones, a removable back cover allows access to a replaceable battery and expandable storage, while the slew of connectivity options are included, like NFC and IR blasters. Mobile connectivity should be no issue either, as both smartphones will be available from every major network carrier in the US.

Where the Samsung Galaxy S5 pulls ahead is with its heart rate monitor on the back and the fingerprint scanner that is integrated into the physical home button. Unfortunately, these features are ultimately useful just for those specifically looking for them. A far better reason to recommend the Galaxy S5 over the LG G3 is its IP67 certification, for protection against dust and water, which makes the Galaxy S5 a much sturdier phone.

lg g3 vs samsung galaxy s5 aa (14 of 35)

If you’re just looking for the usual bells and whistles, either one of these phones will satisfy, as everything from controlling TVs to using Bluetooth headsets is possible. When it comes to battery life, both phones are able to work for long hours, with a plus for the LG G3, because it manages to go the distance even with a larger and crisper display.

It’s in the camera department that we begin to find some real differences, as both LG and Samsung bring their own flavours of enhancements to the table.

The Samsung Galaxy S5 includes its ISOCELL technology, which takes a somewhat different approach to capturing photo data. It does yield some great photos and continues the tradition of Samsung’s great optics quality. Colours are really out there, as is usually the case with Samsung saturation. Details are all captured pretty well in good lighting, but unsurprisingly taper off as the light gets worse. 16 megapixels also give you quite a bit of room to crop and cater your photo if you need to.

lg g3 vs samsung galaxy s5 aa (32 of 35)

LG, on the other hand, has continued to improve its optical image stabilization with OIS+, a feature that more phones should come with. But that’s not all they have done this time around — a laser focusing system helps track subjects much faster, and ultimately yields a focusing speed that is leaps and bounds faster than what is possible with the LG G2. LG’s confidence in the laser system is evident in the fact the camera interface starts off very bare; tapping on the screen both focuses and takes the shutter at the same time.

The Galaxy S5’s camera provides a little more functionality, as well as manual controls, but the LG G3 manages to create consistently great photos in Auto mode, which is a testament to its capabilities. Pictures tend to take on a warmer tone overall in this case, but detail is still captured well and images remain pleasing throughout.

When it comes to quality, I do find the playing field more or less even between these two cameras. The high saturation of the Galaxy S5 shots keep pretty much every photo from being dull, and is at a level somewhat higher than that in the LG G3. Low light performance is about the same on both devices, despite Samsung’s software enhancements and LG’s OIS.

In the end, the Samsung Galaxy S5 provides a little more freedom for anyone who wants control, but the LG G3 camera is the faster performer, with its laser guided system that manages to keep the quality level pretty high.

Finally, when it comes to software, both operating systems received updates meant to refresh what was perceived as overplayed and dull in previous iterations. In a nutshell, the core Android experience is at its best no matter which phone you choose, so the differences are in what the devices add to the formula. Samsung has consistently put new features into its interface, but LG has also made its own strides in providing useful tools.

lg g3 vs samsung galaxy s5 aa (33 of 35)

Starting with Samsung, a new circle motif has permeated throughout the Settings menus, while a flatter look all around did clean things up a bit. Various familiar Samsung features return in the Galaxy S5, like MultiWindow and air gestures. New additions include a Toolbox for easy access to five defined apps, and a Download Booster that uses data and wi-fi in tandem, which helps boost download speeds considerably, but is something to be used sparingly to avoid going over your mobile data limits.

MyMagazine is an attempt to bring a useful second homescreen news service, but its ties to Flipboard make it little more than a full screen widget, that ultimately ends up putting too many layers between you and the content.

What is most striking about the updates to the Touchwiz UI was that, despite all the changes, it still feels like a skin over the same old UI that people either hate or love by now. While the changes are welcome, they are not enough to make a real difference.

lg g3 vs samsung galaxy s5 aa (22 of 35)

When it comes to LG, we do like the direction in which the design aesthetic is heading, though it’s more about hiding eyesore elements, rather than fundamentally changing them.

MultiWindow makes it to the LG G3, which makes perfect sense considering the larger screen. New additions include the Smart suite of applications, like Smart Cleaner, for deleting temporary files, and Smart Notify, which ultimately amounts to little more than a wordy weather report.

The QSlide and QMemo apps are still present, but are hidden behind yet another shade in the notification dropdown. The most useful software feature in the G3’s arsenal continues to be Knock Code, which is an easy way to secure your phone without making it too difficult to access.

lg g3 vs samsung galaxy s5 aa (30 of 35)

In the end, you get a slew of features on both smartphones, but with so many tools at your disposal, the question is, how many times will you use them? I don’t really use air gestures on Samsung phones at all, while on the LG device, I pretty much never use Q-Slide applications. Deciding which one looks better is up to you, but both devices suffer from feature overload, in my opinion.

Both phones are going to fetch premium prices at major carriers in the US, though the Samsung Galaxy S5 has been available for some time now and is currently easier to get your hands on. Unlocked, both phones come close to the typical $700 price point.

And so, there you have it, the LG G3 vs Samsung Galaxy S5. It’s easy to get excited over the larger screen of the LG G3, but even underneath the surface, LG provided its best experience yet. But the same can be said about the Samsung Galaxy S5, minus the massive high-resolution display.

lg g3 vs samsung galaxy s5 aa (18 of 35)

Over the years, LG has been gaining ground on Samsung, proving that it can offer just as much, if not more, in its flagship devices.

We continue to get closer to an even playing field here; LG takes the lead when it comes to the Quad HD screen, while the IP certification remains a selling point for Galaxy S5. In software, the feature lists are arguably too long in either case, though the core experience is as good as ever. Both cameras are great at what they do, though the leap forward on the LG G3 is more substantial than the effect of ISOCELL tech of the Galaxy S5. Finally, when it comes to build quality and design, the LG G3 looks and feels better, in our opinion, than the dimpled Galaxy S5.

While Samsung has always been pretty good, LG is truly coming into its own with its latest flagship. In the end, you can’t go wrong with either of these devices.

    I don’t why there’s so much hate, maybe its because you already own the S5…. but, LG won this year. (Excluding phablets)

  • MasterMuffin

    At least Samsung tried, but they didn’t try hard enough. Less concentration on stuff like heart rate sensor, more concentration on UI and dat rear and S5 could be equal if not better than G3. But nope, G3 wins definitely. 1440p AMOLED would be nicer though :)

    • Lisandro O Oocks

      Not only that, but all those gimmicks also cut down on in-phone storage big time.

      • MasterMuffin

        I would like the option to download them from Samsung apps, not being forced to have them

    • _X_

      I love my S5…AMOLED will always make me buy it.
      The heart rate sensor will be nice if it could monitor your heart rate while jogging…maybe there will be an update soon…SHealth is actually pretty neat if you use it!

      • MasterMuffin

        But should they really focus that much on an app that a small minority uses? I’d rather see TW getting better overall.

        • _X_

          well atleast it is there for the people to use who wants it…that whats nice about Samsung and LG…you get options
          compared to my S2, the S5 feels easier to manage and I like the new menu setup….but SAMSUNG Hub should disappear!

      • kkk

        Instead, over saturation of Samsung AMOLED is somewhat deal breaker for me.

        • _X_

          The nice thing about AMOLED on the S5 is that you can choose your display settings…hence if you dont like saturation put the screen on Cinema mode then you will have the most natural colours and still the best viewing angles!
          The saturation arguments dont hold any water today but still if you dont want it, you dont want it :)

      • mystikalrush

        Its be brutally honest here. 90% of S5 owners don’t give a flip about the health features. Its all a gimmick to get people to buy one. Samsung over saturates, with TONS of unique, yet rather unpractical features that no one really uses.

        • _X_

          I agree, but luckly you get options to turn them on or off…I would rather have the option than not having the feature at all.
          I know that Shealth is gimmic to most people but they can just go and disable it.

        • Mohammad Zahidur Rahman Fahad

          Ya thats true. I only by s5 cause of super amoled, fingerprint scanner, latest hardware, and some how almostnpolished touch wiz. Better than previous versions. Still cartoonish. Samsung need to work on this. And ya, i wanted an ip rated samsung over almost black and white z2 display of sony.

          • kkk

            And again, my opinion on finger print scanner on S5 is S5 version is inferior to i5s version. While i5s version, you can just put your finger on home button but S5 you have to slide down in the most accurate position which is kind of weird and annoy than useful.

            Also newer Sony devices move to IPS panel (finally), the screen is now brighter and more useable in direct sunlight though not the same level as Samsung Super AMOLED.

  • Sandy

    though i used to luv samsung much, i need to agree that LG nailed this year, keep it up LG :) Slimmer Bezels, Laser Autofocus, Revamped UI, 5.5″ screen in regular body, Beast Battery. its very hard to find any flaws in G3. Worth upgrade from my S4, waiting to launch in INDIA

  • kkk

    IP67 in Samsung S5 is somewhat inferior to IP57 in Sony devices because the micro usb flap at the bottom will torn off overtime and when it torn off your S5 IP67 is gone too.

    Meanwhile on Sony devices, you can use dock without open the flap.

    • George Av

      but you still have flaps.. and you can have wireless charging on the s5.. super bias a-hole.

      • kkk

        Bias? So said a Samesung a-hole fan.

        Good luck buying the wireless charging for shitty S5 when Sony have dock included in the box.

  • Brian Samuel

    There was a time when Samsung was king of the Android throne. When S II was released hit it like a bomb and ran figure eights around the competition and it was hailed hence almost in unison in review after review. We have 2014 reached the fifth-generation Galaxy S and the expectations – and competition – is greater than ever before. I know very well that Sony, LG and HTC may well be caught up. But we have come to a time when every smartphone has its own “thing” that they are good at. Which smartphone is best for you, only you can decide!

    • kkk

      Samsung still king in term of sales and profit because Samsung advertise gimmick mislead marketing strategies still work.

      but Samsung have fallen in term of spec feature price
      1. Spec since Samsung spec marketing is lost because most flagship have almost same spec now unlike the past where LG HTC Sony spec can’t caught up with Samsung
      2. Feature since Samsung keep add those gimmicks and they don’t listen to customers enough
      3. Price since Samsung think that their Samsung brand can put on the same price tag as recent iPhone.

      • kg2105

        1. You can’t call that falling when the S5 still has the same best processor and arguably the best screen, even with the G3 out (colors, brightness, viewing angles are all way better on the S5 than G3)
        2. Samsung can price their phones like iphones, because they are much better devices than iphones. Same with other oems, if you think Samsung has gimmicks then Apple is much much worse. Small/lowres/dual core/simple device that costs more than any android device (except the overpriced Sony Z2).

  • Coaster26

    Okay, so I know that the Samsung will be better at dust/water resistance…..but I’ve never had a phone have issues because of either one of those, so it’s not a big factor for me.


    I will be buying one of these for a teen soon. Which one is more drop-proof without a case? Which has a more protective case available? Which has better parental controls, if any?

    • Paul McNaney

      The Samsung Galaxy s5 has a unique Kid’s Mode. It is absolUtley PERFECT for my kids. They can’t access any private data, like photos or work documents, but they can play games and do things kids like. Look up a review, it really is perfect especially with an Otterbox Defender case on it, or a Lifeproof case. At the Verizon store, my salesman sold me the otterbox case by putting it on his own phone, then throwing it across the room at the wall. Not a scratch on the galaxy s5 (or even on the case). The combination of the Samsung galaxy s5 with an otterbox defender case would be perfect for your teen. My kids have dropped theirs many times, even on cement outside, and no scratches or damage anywhere to be seen. Plus the waterproof galaxy s5 means the rain won’t harm the phone which is great for younger irresponsible teens.

      • Terry

        The general has it too it’s called guest mode

        • Terry

          Sorry g3 has it as well I meant

  • JP

    Someone forgot to include battery in the comparison. That should have been a +1 for LG.
