In pictures: The differences between the Sony Xperia Z4 and Xperia Z3
Announced three days ago, the Sony Xperia Z4 is a conflicting device. To start off, while it satisfies Sony's long-standing rule of refreshing their flagship line twice a year, some would argue that it fails to satisfy consumers' need for more palpable upgrades. Indeed, the Xperia Z4 is a lot alike the Xperia Z3, which, in turn, was a lot alike the Xperia Z2, which was... you guessed it – a lot alike the Xperia Z1.

And yet, the Xperia Z4, which is currently exclusive to Japan and will launch under a different name in Europe, does offer improvements over its predecessor, some of which significant. For example, the device leapfrogs Qualcomm's Snapdragon 805 processor, and is making a jump to the Snapdragon 810. That's a noteworthy upgrade, considering the Z3 has Snapdragon 801 on board. Also improved is the front-facing camera – a traditionally weak spot for Xperia devices – and the unit is now touting 5.1-megapixels and wide-angled lens for superior selfies. Last, but not least, the Xperia Z4 has also slimmed down, and is only 0.27 inches-thick (6.9 mm).

All of this you could surmise for yourself as soon as announcement day, however. But what about the smaller details, the ones you can't make out from a specs sheet? Japanese RBBToday has taken a number of photos of the Xperia Z4 next to the Xperia Z3 in an effort to exemplify just those. They include a break from the flaps-heavy design, and a move to a more flush frame and an easily accessible charging port (which is still waterproof). In addition to that, Sony has done away with the extra magnetic port on the side, moved the front-facing stereo speakers to the very ends of the top and bottom bezels, and has also moved the microphone on the top frame to the other side.

See for yourself.

If you own Z3 then there's no need because this is Japan exclusive. You could have troll better than that.

@ techperson211, He is a loser Samsung fan pretending to be a iPhone user (just like that losersmurf). He trolls every articles. He even trolls on apple articles but never say anything bad against samsung. Don't expect good comment from samsung fans. @KENTOZ, Xperia Z4 is much better than the $6it samsung phone you use.

I have to admit... as an hardcore xperia fan, the Z4 has really disappointed me. I was expecting way more than what it actually is......

Lmao I still see you're hurt from last time. :) Keep thinking I don't have an iPhone. At the end of the day, I'm happy with my 6 Plus and you're crying and worrying about what other people do. Please take a seat and evaluate your life you pathetic troll.

Really? Look at the photo of the S3 and Z4, they look 99% identical. No matter what phone he likes, that doesn't change the fact of what he said. It's basically looks like they took the Z3 and held it to a mirror because the camera and light sensor are exactly on the opposite side as they would appear in a mirror. Also here is the Z3 and Z4 side by side. The only new thing is the SD810 over the 801 and the Adreno 430 over the 330. Everything else is exactly the same. It has nothing to do with being a fanatic and it isn't trolling. The Z3 and Z4 are the same phone. Basically they took all the leftover unsold Z3's and reverse the from panel and bumped up the CPU and GPU. Everything else is exactly the same. This is why Sony Xperia is at the bottom of the barrel and why Samsung outsells them. Its junk. They are worse than Apple selling the same phone 2 years in a row with just minor speed bumps.

Buddy,that's his own opinion,not yours.And where did he mention Apple or samsung?He just said both look similar,for you they might not look similar but him it does.You seem a blind fanboy + hatred for other companies.And Z4 is not even launched apart from Japan,don't keep bragging around that its the best,let the reviews come out.

Xperia Z4 is very elegent and sleek looking phone. Especially, the golden Xperia Z4 looks really sexy. IMO, Z4 has better design than Z3. Z3 has too many ports, whereas Z4 has much more uniform looks. So, Good job Sony.

Only if you're delusional. Enjoy your protruding S6 camera.

Who cares if it protrudes? All the cameras on the Galaxy S protrude. The only difference is this time, they didn't mold the case to fit around it. If they had done so with the glass back, that would have been a focal point of breakage if you drop the phone and it hits the raised glass. When Samsung used plastic as the case materials, they simply raised the plastic around the camera sensor. With glass you shouldn't do this. But you wouldn't understand, because you've never worked with glass.

the improvement after 6 months is very good. Where you can get the 6.9mm with 20.7 MP camera (NO PROTRUDING) plus a glass on glass design plus a over 2900mah battery plus a water and dust resistance plus a stereo speakers towards your ears not your foot and don't forget the metal-frame. and please remember, all above in one smartphone. For example Iphone 6, yes it's thin, nice design, but with protruding camera and poor 1810 mah battery and doesn't resist water and dust and mono speaker. The same goes for S6 and S6 edge or you look at the M4, yes it has dual speakers, nice design but very thick and still you need to keep it away from water and dust blah blah I have to admit that no manufacturer can make the phone like z4, even z3. What they need is the new marketing officer.

Those protruding cameras put the 20 MP camera on xperia phones to shame. They just pack better lens systems which takes much more space. Also, OIS and PDAF which xperia devices lack.

You do realize that iPhones use 1GB of DDR3 Ram, right? let me break it down for you: 1x3= 3. According to my calculations you're stupid enough to be mad about a phone using triple the Ram in your phone. Sorry but that's really stupid.

I think DDR4 is better, do you agree?

of course, but he's saying the z4 is bad with its 3gb of ddr3 ram yet his iphone is 1gb ddr3 and won't see an increase anytime soon. just pointing out that he's stupid.

Lol nice troll, you even have a sock puppet account down there. How did PA even get that information when Sony's own white paper doesn't specify DDR4 or DDR3? I guess you didn't even bother to waste your one brain cell head on that thought, because your hands were already racing to type out your troll.

Those protruding camera doesn't put Xperia phones to shame. Keep your biased comment to a certain limit. PA did a comparison between Samsung Galaxy S6 and Sony Xperia Z3. The difference iof the image quality isn't that vast. While S6 camera is certainly better than Z3 it is not miles better that your comment suggest. And you need to stop posting your bulls**t comment on every Sony articles.

I dunno, I would say the S6 camera is miles better. Does the Xperia offer OIS? Does it offer Fast Tracking/Auto-Focus? Is it 1.9 aperture? Just the Sony acmear app open in less than a second? If it doesn't match all 4 then its miles behind. What is amazing is, Sony makes the sensor used in the S6. Samsung added their own features to Sony's sensor and made it better tha Sony does for its own phones. Yet the Xperia costs more than the S6. Sony and Apple have a lot in common. Forst, they both sell the same phone 3 years in a row with minor spec bumps. In this case, they went from SD801 to 810 and from Adreno 330 to the 430. All the rest of the parts are leftovers from the previse model. Apple to the A7 of the iPhone 5S and simply renamed it the A8. Its the exact same chipset bearing the same exact model number. All they did was clock it up from 1.3Ghz to 1.4GHz. But at least with the iPhone 6 Apple changed the design of the phone. Sony didnt even do that. They basically held the Z3 to a mirror and made it look exactly like a mirror image.

OK, I get your point. And How about the Battery? water dust resisteance? stereo speakers ?

Posts: 1655; Member since: Jun 02, 2014

yup it's no different with z3. And stereo speaker is gimmick. Thick bezel is inelegant.

I agree thick bezels are inelegent, good thing Z3/Z4 has one of the slimmest bezels of the mainstream brands.

Trust me. I bet you never use the 2 fronts speakers phones. I used to think the same, untill I have a chance to use the moto G 2014. Then m8 now a z3 compact. I cannot switch back to use my old LG G2 (my father uses it now) or my brother Samsung E330 (s4 LTE-A) or my sister-in-law IP6. Stereo fronts speakers now is the must for me.
