[Xperia Z2 Q&A, Help & Troubleshooting] _delice_doluca_:
-Yes, the spaces are real problem as Sony is already guilty about this from the previous phones. Luckily mine does not have any but that does not change the fact that they exist on many phone

- No idea about that one as I only read 1-2 things about it and never faced it in reality (me, my brother and my sister's husband bought 3 Z2s together and than my sister got an Z3 and none had any problems so far, so no experience on this one)

-Overheating is not an issue about daily usage or even heavy usage. It only matters on video recording because when video recording not only CPU cores and GPU being used at the same time but also camera processor (I don't know how this one is called) is heavily working to "catch" all that detail (simply taking 30, 4MP photos every single second and has to catch the light and decide for each pixel). Other than that I have not witnessed overheating cousing disconfort or slowing to phone down (I tried playing games more than 2 hours).

- Again, I haven't experienced this either. So no comments here.

- Camera software is really good actually, every setting is there but raw format. Only bothering thing is the AI which is supposed to choose the right settings. It behaves too "human-like" and "emotional" thus resulting some unrealistic color reproduction sometimes. So if you have time (Hope it's not a bird that you are trying to catch) and patience, it's best to make manual setting.

Anyway, apart from the subjects you mention, Let's compare what the "rivals" offer;

LG: there is G3. unnecessarily high screen resolution with a result that is not any better than Sony's screen thus also resulting worse battery life and more waste of GPU power. Although I like the design, and the placement of the buttons to the back side, very much; Sony has more premium materials and better camera with better results against the OIS, laser focusing camera of LG's.

Besides, G3 comes with two different amounts of RAM which makes me take the company as "disturbingly arrogant after the succesfull Nexus 4,5 and G2 and quickly forgot the days that they were punished by the customers' wallets because of locked bootloader of Optimus G and other unsuccesfull phones". Still, they choose to make things harder for developers after a very developer friendly G2. I believe there is no match in this land to Sony.

HTC; One (M8). HTC has been trying to bring some changes to the game since long time with their Beats Audio and other audio projects. They also tried to change things in the camera section too. I can't say they are doing bad things but I believe 20.7MP is still has higher capability of catching the light better than dual 4MP, bigger pixel camera. And I also believe (and tested) Sony's sound capabilities are better than HTC's when it comes to headphones (which is what is really important for a true music lover in my opinion. Who can truly enjoy the music from a mobile devices speakers? Want real music, use the jack)

On the chipset performance section, One (M8) is still not a rival to Sony's Z2. Not talking about the battery, it's 2600MAh.

Besides (I don't know if things are different from my One X days) HTC devices come with an extra security to try to prevent you from unlocking bootloader and saving themselves when they need to honor the warranty. After losing my patience over my One X's waiting for an S-OFF solution, I run away from HTC and never looked back (I can't even consider Nexus 9, thinking Nvidia and HTC coming together is like another Saw movie, it scares me). In a world even jailbreaking is legal that is too much for an Android user to accept.

Let's come to Motorola/Google; Nexus 6. It's a great rival, an honorable one. And maybe the only one with the ability of putting a real fight. Still, with that 6" screen it's not everyones cup of cake. Design and the specs are gorgeus, so is the screen. But it's big. I came to Xperia Z2 after a long time Note 2, then Nexus 4 usage and it feels right with 5.2" screen. This one is about preferences though, not the actual spec comparison.

Nexus 6 becomes a real deal with it's AMOLED screen (not calibrated by Samsung thankfully), water ressistance, best CPU&GPU and it's cutting edge software. However, when it comes to one-hand compatibility, MicroSD card expantion chance, camera and soudn quality Sony still has it's advantages.

And finally Samsung; S5 and Note 4. I guess I should take Note 4 into account as it's newer and better. Samsung has fingerprint sensor as different from it's rivals. A nice one to accept.

I understand that Samsung is a hardware making company. So they have to create and sell their hardwares and it's easy to see Quallcomm dominated the market since the Nexus 4 attack. Google did this to unify the market. Since the S4 Pro evey Quallcomm chipset has great similarities on their softwares and drivers, mostly their performance vary. This helps developers to measure their fresh-written apps/games on 1 or 2 devices and easily make sure they will run on many devices out there. It sounds good right? Well, Samsung is always bringing their SoCs to the market and always trying to push the limits (sometimes by cheating on benchmarks). On the raw power side, that could seem as a good thing but on the software side it messes things. As a big part of the market, almost every developer has the feeling to make their game/app compatible with Samsung devices. But they come with different SoCs and Samsung refuses to share their own chipsets' source codes. So they just make everything harder for developers. I guess we all know that a well optimised software is always better than the highest hardware.

One more thing about Samsung, they are first company to open their bootloaders to the public and shared every necessary code on their Galaxy S days. This is how they got so respected and made all that money. So they still have the unlocked bootloader but with some ir-reversable flagging system that flags you if you alter anything as small as a rooting attempt to your system. And then, they claim you out of warranty. Besides, as they refuse to share their source codes for their hardware, most developers have really hard time preparing custom ROMs or early fixes etc. for Samsung phones. So basically, Samsung tells you that "you have a phone which comes with an unlocked bootloader so you can do whatever you want with it.........If you can"

If you are a fan of Samsung's software and policy than it's a good semi-independent eco system in Android world. The S-Pen is also good. However I can not take them anymore after the Note II's hard days, waiting for a simply working AOSP ROM.

I know there are other Android companies but these are best-known ones globally and after that comparison I believe Xperia Z2 started to seem better in your eyes. If still not, I can also remind you;

-Sony is the only company which update kernels too,

-Sony is the only company which provides the AOSP code for their devices (the other compaines rather selling their devices as GPEs but apperiently Google has taken this idea down)

-Xperia Z2 has the best music experience throught the headphones among it's rivals

-One of the best (If not best) cameras out there

-Has that DRM keys problem for the "discoverer" people like us but thanks to our developers there is cure to that.
