Interface and Functionality

The LG G3 brings a simpler UI with less clutter and modern, flat looks than before. Sony, in turn, builds up on the successful legacy of its earlier skins, and delivers a consistently good-looking UI.

Both the LG G3 and Sony Xperia Z2 come with the newest version of Android, 4.4.2 KitKat, on board, but they feature two very different custom skins that make the user experience differ as well.

The G3’s skin is a departure from the cartoon-y LG UI of before, coming with temperate colors and a mellow vibe, modern, flat and sharp-looking icons, and much less clutter in an orchestrated effort towards simplicity. Sony’s Xperia Z2’s UI, on the other hand, has not joined the ‘flat’ trends of modern design, but still looks very modern and stylish, plus it has had simplicity as a driving force from the onset. In the Z2, in particular, Sony’s UI has evolved just slightly, getting more polished looks and smoother animations.

Despite its crusade towards simplicity, the LG G3 custom skin is still much more packed with all sorts of features and apps. On the home screen - LG pounds large, nearly screen-wide widgets and a separate panel with information from its Health app and some tips, while Sony’s widgets are less intrusive.

Some of the new additions in the G3 - features like the Smart Notice assistant that is meant to remind you to take your umbrella before you go out on a rainy day, or prompt you to return a missed call - feel more subtly embedded, so that they don’t get in your face too much, but not all. Other neat features like the Knock Code sequence that you can tap on the lock screen to go securely and directly into the home screen are unique to the LG user experience. You also have Guest Mode on the G3 that you can access via a separate knock code - and that’s convenient for the times when people ask you to see something on your phone, but you don’t want them to see anything private.

Switching to apps, LG has joined the fitness craze with its Health hub that tracks your exercises and daily activity. Sony is also well equipped on the health front with its Lifelog application that does even more - it collects your fitness stats along with your phone usage stats, to create a fuller picture of your day, plus it even maps it all.

In terms of basic functionality, the phonebooks are similarly rich on both, but Sony’s simpler UI feels zippier in the core apps, while on the G3, just opening the dialer often happens with a hard-to-explain slowdown. For messaging, the G3 has a redesigned keyboard, matching the new flat UI, but it’s also very flexible and you can adjust its size. While such fancy options are not present on the Z2, typing is about equally quick on the two as keys on both are large and well-spaced.

Processor and Memory

The two have just slightly different flavors of the quad-core Snapdragon 801 on board: the G3 is a bit more powerful, but the sharper screen drags its performance below the Z2.

The LG G3 and Xperia Z2 are both new devices, a part of the wave of Snapdragon 801 flagships, and while there are some minor differences in their processors, they have roughly the same silicon muscle. The G3, however, has a heavier load with the extra heft from the higher-res display, and while it does not lag, some apps load a bit slower on it. The Xperia Z2, on the other hand, feels zippier in daily use, plus it also crunches benchmarks better thanks to its lower-res 1080p display.

Digging into the details, we see that the G3 runs on a Snapdragon 801 MSM8974-AC, while the Z2 has the Snapdragon 801 MSM8974-AB. Both are quad-core chips, with the most notable difference being the clock speed - the G3 gets to as high as 2.5GHz, while the Z2 can run at up to 2.3GHz. In terms of graphics, both are powered by an Adreno 330 GPU running at up to 578MHz. We did not see any lag in games that could have been caused by the added strain of the higher resolution on the G3, and both handled most titles with ease.

Interestingly, the G3 comes in two versions - a 16GB one with 2GB of RAM, and a 32GB one with 3 gigs, while the Z2 features 3GB of RAM even in the basic 16GB model. Both support expandable storage via microSD cards of up to 128GB.

Internet and Connectivity

Both feature 4G LTE connectivity and surfing the web is zippy and enjoyable.

LG bundles both its custom browser and Google’s Chrome to surf the web on the G3, while Sony has gone just with Chrome on board. Both LG’s custom browser and Chrome are zippy, but Chrome is the one that has cross-device syncing and the slightly better optimized card-based interface. Pages load and render quickly on both devices, though, and scrolling around and zooming in and out is practically free of lag.

In terms of connectivity, both the G3 and Z2 come with 4G LTE support, with download speeds of up to 150Mbps. Other connectivity options include dual-channel Wi-Fi, GPS, and NFC on both. The LG G3 also has an infra-red (IR) blaster located on the top that you can use as a remote control for your TV, or other electronics. It’s a neat addition for those times when you can’t find your regular remote, and it’s a feature that’s missing on the Z2.

I don't mind bezels. At least there are some great speakers underneath them. And the overall design is just so beautiful!

Well I do, yes speakers are the best out there, but I don't like how they've done the bezels. The M7, however was great.

Zero bezels are more yucky!

No, The particular bezel on the M8 are just yucky to me. Much bezels don't essentially mean bad design, but if they're done badly they can affect the design terribly. Well at least This is my opinion, you may not agree with me.

There are two breaking point for me to go with the Z2. 1. Waterproof - I thought this feature is just a bonus, but after having Z2 for two months it's a feature I can't part with. 2. The headphone jack is on the top - I put my phone in my armband when I run and having the port on top is much easier to plug it in.

Not really, Z2 is easily the winner here.

It came out much later but the Z2 is still one of the best.

Victor, aren't those Z2 photos taken in 8mpx and manual mode? Why not 20mpx or at least superior auto and 16:9 aspect ratio (in superior it has a slightly higher resolution)?

Z2 for me. Every category is pretty much a draw, but after having an Xperia Z there's no way I can go back to a non-waterproof phone. Showers just wouldn't be the same lol

I agree. After having my s5 in the shower I'll never go back to a non waterproof phone

Why do you guys like having your phones in the shower? Watching dirty films to simulate things not there?

35. mistertimi

Posts: 77; Member since: May 28, 2014

Haha not gonna lie, I've knocked one out with my phone in the shower ;). But the ability to put it on loudspeaker while talking to someone, or just listening to music/being able to switch tracks etc or just watch tv is epic

This is not necessary you made it as your necessity.

It's necessary because I shower everyday, and like doing so with my phone. Sure it's not a necessity like the ability to make phone calls or send texts.. but then again, barely any features are. I'm sure many people wouldnt leave the iPhone 5s because of the fingerprint scanner. Couldn't they just use a pin or password instead? Sure, but it's a necessity for them. It's what they need from a phone in order to make the purchase. I NEED a coffee in the morning. Of course, if I don't have it I won't die lol, but you can bet that I'll be in a worse mood. Same as if I couldn't watch stuff in the shower, or the i5s people couldn't unlock their phones with their fingerprint. Please don't nitpick Gaara. We all know Naruto schooled your ass in full-blown one-tailed form, don't make me go Sage on you ;)

OK so you mean only water resistant phones are good because you take shower with them? That can only happen in my Infinite Tsukuyomi :p (I'm no gaara fanboy :p) I wish what would be everyone's reaction when phones become fire resistant ,lolz .

Two good options. I expect people can choice them instead of only thinking about Galaxy.
