Interface and Functionality

The outer style of the Z2 is complemented by the clean and sleek Xperia UI, while the Optimus skin on the G2 is a bit too cartoony.

The Sony Xperia Z2 arrives with the latest version of Android, 4.4.2 KitKat, with Sony’s Xperia custom user interface on top. The LG G2, on the other hand, is being updated to KitKat in some markets, but unfortunately our unit is still running on the dated Android 4.2.2 Jelly Bean.

The actual difference in the looks of the interface, however, comes mostly from the different skins that the two phones use. Sony’s Xperia UI is clean and light, with little clutter and a pleasingly uniform design language with modern iconography and snappy animations, all combined leaving a distinct feeling of a Sony Android experience. LG’s Optimus UI, on the other hand, has this cartoonish visual style that is uniform in itself, but comes in dissonance with the vastly different looks of pure Google aesthetic within some apps, and lacks that flow and refinement.

The Z2 is not all that rich in terms of added apps and tweaks and tricks, but this also means that its also more gimmick-free. The G2, on the other hand, is just stuffed with little features and settings, some of which are good, but others seem over the top.

Most basic operations on the two phones are different in looks, but similar in functionality. The phonebook app is rich and detailed on both, and it conveniently supports swiping between tabs (we also love little details in LG’s Optimus skin like the capability to call a contact directly without accessing its file).

The virtual keyboards on the two phones have a different style, but the typing experience is good on both as buttons are well spaced, and typing is fast and easy on the big, 5.2” displays. The Z2, however, with its larger size, is less comfortable for single-handed typing, an issue that is not all that apparent on the G2.

Processor and Memory

The Snapdragon 801 system chip aboard the Z2 along with 3GB of RAM gives it an advantage in the spec race, but the G2’s Snapdragon 800 is a great performer as well.

The recent arrival of Sony’s Xperia Z2 gives it the advantage of being equipped with the latest and most powerful Snapdragon 801 system chip, but while the LG G2 has yesteryear’s Snapdragon 800, the difference between the performance power of the two is not immense. In fact, for common daily tasks, both feel very zippy, and it’s a rarity to have something stutter.

It’s also true, however, that the Xperia Z2 is the more future-proof phone, with its latest internals. The Z2 sports the quad-core Snapdragon 801 chip running at 2.3GHz and features a plentiful 3GB of RAM. The LG G2 has its Snapdragon 800 run at 2.3GHz as well, but has a lower amount of RAM - 2GB.

For gaming, you have the Adreno 330 GPU on both handsets, and both are capable of running the latest and most graphically intense titles in admirable detail and with smooth framerates.

Internal storage is 16GB on the most basic model of the Xperia Z2, while the G2 has double that allowance, with 32 gigs on board. You can, however, expand the memory via a microSD card on the Xperia Z2, while you cannot do this on the LG G2.

Internet and Connectivity

Both feature 4G LTE connectivity and other essentials, but the G2 has got an IR blaster, which is a nice extra.

Sony has taken the sensible decision to go with just one built-in browser (Chrome) on the Xperia Z2. This comes in contrast with the LG G2 and many other phone manufacturers who bundle-in two browsers. In the case of the G2 we have a custom LG browser and Chrome, that you have to pick between. The browsing experience itself is excellent on both devices - pages load and render swiftly, and scrolling around and zooming in and out is free of slowdowns and stutters.

In terms of connectivity, the Xperia Z2 and G2 are similarly well packed with 4G LTE on board, but the Xperia Z2 has just a slight edge as its 4G LTE modem supports higher download speeds (up to 150Mbps on the Z2 vs up to 100Mbps on the G2). Other connectivity options include dual-channel Wi-Fi, GPS, and NFC on board of both.

The LG G2 also has an infra-red (IR) blaster baked-in, and you can use it as a remote control for your TV, or other electronics. It’s a great addition for the times when you just can’t find the TV remote. The Xperia Z2 does not have such an option.

I can't believe I'm going to defend an LG device, but... Did we read the same article? Sure, the Z2 has the benefit of being the newer device, but "owned"? If anything the Z2 looks like it comes out short considering the tech it advantage it should have, but doesn't quite capitalize on.

G2 is still a great phone at its price! ONE OF THE BEST CAMERAPHONE, GREAT BATTERY AND GREAT SPECS AND PERFORMANCE! Z2 will not win against G3!

also the G2 is older than the z2 and i'm sure the G3 will crush the z2 in many aspects

Z2 for sure, We must wait for G3 which can be the most powerful competitor to the best smart phone of the date, AKA Z2.

Z2 the best smartphone of the date? except the design wich is nice but the phone is to heavy and bulky and thick bezels (not to speak about the ugly so last decade icons like in the old Sony Ericsson K500i), it doesn't beat the S5 at nothing. So the best smartphone title is a little bit forced. My rankings are: Htc M8 - the best looking and speakers S5 - the most powerful (camera, processor, sensors, IPXX certification, software except a little bit lagy Touchwiz) G2 - best value-for-the-money

My Z2 rocks but I kinda miss my Note 3. Even with dating specs, I still think that it's the best smartphone money can buy right now.

I can test it more later today when I go play badminton. But it's supposed to calculate your steps, calories, how much walking, running or cycling you have done. Also it tells you how much you have listened to music or using social media. But the feature I'm the most interested in is the sleep time calculation and "smart wake up" lol. It should vibrate on your wrist and thus wake you up. I hate the sound of an alarm clock so I'll be really waiting for my wake up tomorrow!

Too excited for the Z2 vs. G3 comparison. A true clash of the underdog titans.

The G2 wins because the Z2 is ridiculous large while the G2 isn't.

you can get a g2 on swappa for less than $300. z2 is a great phone, unfortunately their software is even uglier than touchwiz and the phone is hideous, imo. also, not that it makes much of a difference, but why is the g2 still on 4.2.2?

Amazing... cpu gets hot on z2, throttling lowers the CPU, lower scores, lower porformance on apps and games, and you are telling me Z2 is better? it costs twice as the G2! Paid Versus?

Big deal if it gets hot. I've got my Z2 yesterday and I've already Rooted it to 2.7Ghz and a raise in Gpu up by 150mhz My Z2 gets even hotter reaching 47+celcuis. I'm not complaining What do you have baby hands that you must touch that section where Cpu Gpu gets hot. Why touch that section You must be. A female might I assume

Its amazing how mobile phone camera is evolving, I mean last year G2 was in the top in android devices and in this comparison the Z2 just beats the G2. I like this competition, which eventually will end up in a near DSLR like capabilities and imaging..!

G2 is the best smartphone "BRANDED " for its price tag! G3 is the next KING!

I just cannot believe the appreciation of beauty of this website. The appearance of G2 just looks fancier from everywhere than the Z2. At least it doesn't look like old or something.

As I see, no matter the Z2 or GS5, their cameras are just a little bit better than that of G2.
