[Xperia Z2 General] zodiac100:
I've had mine since the 17th of April and I haven't experienced most of the problems the OP listed. I've had the 4k over heating force closing camera app but that was only on the first day because I was already using the camera for ages before testing 4k. Since then it's never happened again. Never happened with 1080p video at any point even 60fps.

No problems with lte or wifi. Don't use bluetooth much so can't comment there. Automodes work OK for me. Well it's just the night mode I used so no extensive testing done there.

Z2 rocks, put it this way, I've spent a lot of time criticising most of the Sony Ericsson and Sony devices I've owned but the z2 ain't gonna join that list.

The display is class leading, whites may not be the whitest but they're white enough. The colour reproduction is spot on despite the vibrancy unlike you know who. Performance is boss too. Only notice frame drops in games when the phone gets very hot after prolonged periods.

Sound quality is great too and I for one don't have any problems with notifications. I hear them from the living room when I'm outside. I also like the fact that it automatically adjusts the sound volume depending on what you're doing. It's loudest during gaming. I think that's good because I can just leave the phone on full volume and it automatically takes care of everything. No need to keep adjusting the volume. Another thing I discovered is that you can zoom in on any video you record with the device, not just 4k. Obviously not as much detail is preserved but it's great nonetheless.

The camera for me is the real star of the show. Not really a superior auto man because historically that produced the worst results possible especially with the Z. Not this time though. Manual for me is still king but superior auto has been greatly improved and you can be happy using it. It actually does a better job at white balance under artificial lighting. Something I hope is addressed in manual mode with software updates.

As for photo quality, it's fantastic at 8mp. Sure you can't zoom in as much as with 20.7mp but the quality is much better in ever respect. Detail preservation, colour reproduction, dynamic range etc. Fantastic job done here by Sony. They've certainly joined Nokia in the premier league of smartphone cams. If the lumia 1020 is an incredible 5mp camera, think of the z2 as an incredible 8mp camera.

Took me a while to get used to the size of the phone though but I'm over that now. Z starting to look an feel small now lol!

All in all, it's not only by far and away the best effort from Sony, it's the best smartphone ever built. It's monolithic rectangular design might not be everyone's cup of tea especial those who like to grip their phones but I love it and hope Sony never changes it. To give you some perspective, I absolutely hated the xperia arc design. That's just me I know. The m8 might feel more premium but I think it's butt ugly with those juvenile speaker grills. I actually prefer the s5's look if not feel.

There's more to talk about especially the noise cancelling genius. Works like a charm and does exactly what it claims to do.

It's also pretty solid and rugged. I've dropped mine a few times and it's shown no damage at all. I'm glad Sony went back to the original z design and put a plastic edge around the aluminum frame. My mates z1 is already showing signs of age but the z still looks fab. I think z2 will stand the test of time much like the z did.

For the bad, the phone is way too slippery hence why I've dropped it a lot. It even slides off surfaces on its own lol.

The camera also tries to force the bokeh effect on you. If you have anything that remotely looks dominant and central to the scene, the camera tends to blur out a bit objects in the background. IPhone 5s does this too but is sort of annoying especially when the z2 has a dedicated shooting mode for this. Admittedly one that's not the most accurate. Well even m8 with its secondary depth sensor is inaccurate so let's not take the high ground here.

To avoid rambling on, this is one phone I'll gladly recommend to anyone who isn't worried about size. For those of you that are, just wait for the z2 compact.
