Samsung Galaxy S5 vs Sony Xperia Z2 vs LG G2 specs comparison

Samsung Galaxy S5 vs Sony Xperia Z2 vs LG G2 specs comparison
We can't help it but stage a fight between what will be the flagship handsets this spring season - the newly-announced Samsung Galaxy S5 and Xperia Z2, and the reigning finest by LG - the G2. All three sport 1080p displays, processors of the Snapdragon 800 family, and high-resolution cameras, but there are more than enough differences to go around, too.

The Galaxy S5 is pretty close to the overall dimensions of the Z2, both being waterproof handsets. The G2 is much shorter and appears more compact, despite having the same 5.2" screen size as the Z2. It has a 13 MP camera, compared to the 16 MP on the S5, or the 20 MP of the Z2, but LG put optical image stabilization in it, so it still counters the other two. 

Of the three handsets only the G2 doesn't have a microSD slot for storage expansion, yet it comes with 32 GB of memory out of the box. Sony tops the rest with its 3 GB of RAM, and is also the phone with the largest battery capacity. The Snapdragon 801 processors in the S5 and Z2 allow 4K video recording and selective focus in the camera app, while LG G2 makes do with "only" 1080p video recording.

Given the specs, you can't go wrong with either of these, and they have enough unique features that separate them, too. The LG G2 moved its physical buttons on the back, allowing for a more compact handset, and easier one-handed operation. The Galaxy S5 sports a Finger Scanner in the home key, as well as a heart rate sensor, while Sony's Z2 counters with stereo speakers and premium design. Which one would you pick this season?

G2 because it has power, design and OS..

Is that a joke? G2 is the most underpowered of the three. Design and OS are both tossups but power is simply not true

I have to agree with you. Both S5 and Z2 are very much a refresher of their little brothers. However, they are still very good phones. For me who is upgrading from the Nexus 4 to one new flagship soon, I might have to go with Z2 because I love the water proof feature and the front facing camera. I wouldn't trust the S5's water proof just yet, because their failure with the S4 Active. However, other aspect S5 has a small advantage over Z2. I am going to see what HTC has to offer. They need to move their announce date earlier... this is killing me XD But for now, I am set on the Z2 as my next phone

The samsung S5, what an EPIC Fail lol! 6 months old G2 is better in every aspect..

6. HASHTAG unregistered

The Z2 probably wins, though the S5 will still outnumber the Z2 in sales.

They all suck pretty hard. The LG G2 is too big. The S5 is way too big and the Z2 is bwhahaha way WAY too big. The HTC One new is going to fail even harder because that is just what HTC does. My Nexus 5 is better which is quite sad.... The LG G3 is the last hope....

Holy crap! It weighs more and is bigger than the G2 while still having a smaller display, a WORSE camera and smaller battery. HA!

The one time I tried a G2, its video recording option couldn't even get close to 60fps, let alone hold a steady framerate. The optical stabilizer also didn't make much of a difference (though I didn't have time to play with it long) so I don't know how you can easily classify it as a WORSE camera. Why are so many sites and reviews always mentioning the G2's 60fps recording feature anyway when you need some serious light for it to not drop frames.
