the xperia flagship thing, that happened with the Entire NXT series, none of those phones got 4.2.2 like they were supose to and most of them didn't receive firmware updates for atleast 9 months

Xperia S, SL both recieved a very slow and buggy 4.1.2 build and Xperia SP was left with a buggy 4.3.1 firmware but at least was updated for a while

Xperia P i think got a stable firmware

and Xperia U got a stable firmware too but all these devices excluding SP all recieved firmwares late too , they delayed ICS for about 6 months

im not saying those devices are faster, im trying to explain why Z2 firmware isnt as good as it should be

use a xperia Z on 4.4.4 it feels fast and responsive, compared to Z2, it has this slight slugishness behind it, the same applies for Z1 it feels generaly slightly better, unless all 3 Z2 replacements ive had have been faulty then this is what im experiencing

these problems im having atleast are usualy happening with non modded firmwares, i get policy conflictions, swap conflict ions, security certification errors

and for battery these sites claim Z2 can reach 14hours of screen on time only once i could do that and currently at the most i get 7hrs,

some of these sites claim they can get upto 89hrs of use and im sitting over here with about 22hrs with all kinds of mods and tweaks to prevent wakes and unecccisary process use, i dont even use my phone this much

i know some of these companies which say Z2 reached past 30hrs claim they didnt do anything to the device but im seriously doubting that

i think both Android authority and GSM arena claimed these statistics on Stock firmware
[Xperia Z2 General] zkyevolved:
I wouldn't dismiss ALL the battery tests. I can get 2 days battery life, and with 4-5 hours of the day I have 1 bar or 0 bars coverage, which is a battery eater.

I can get around 5-6 hours of battery life with no mods whatsoever... I think that's more than enough for me. I have never felt the need to charge my device midday. It did take my phone like a week to get to a stable charge cycle.

I actually have now my third defective device, and I'm waiting for a new batch. All are now W19, and I want another batch. I've had hallow sections of the device where the glass bends very easily, on another device I couldn't hear the other party at all. On this device i can hear just fine, but they can't hear me if I hold the phone to my face with my shoulder (I grab it again with my hand and they can hear me). So I don't know. If I get a 4th defective unit and it's not W19, then I'm going to see what I'll do. Because I've never had defective devices with Samsung. I also had 3 defective Apple devices. I don't want another iCrap or a cartoony Samsung device. I'm kind of done with them. I really REALLY like Sony! So... I'll keep my fingers crossed :D But battery life is probably the best I've ever had on a device without an extended battery (blackberry days lol)
[Xperia Z2 General] lee480:
You're absolutely correct. In fact, none of smartphones, including SAMSUNG, running NovaThor platform gotten beyond Android JB.

I'm running an Xperia Ion, which is essentially a larger version of the Xperia S and I can say your assertion is total bull's crap.

Xperia P's firmware wasn't delayed.

And by you using the world "think", simply shows your statements are full of assumptions that lack substantiation. Clearly you haven't research thoroughly before opening your mouth. Xperia P received ICS way earlier than Xperia U.

That's your "feeling". Whether it is true or not, your know yourself the answer.

????

Again, this simply show lack of proper research when you post stuff. The 89h You extracted from GSMArena is only a comparative value of the battery's endurance for comparison with other phones and NOT the real time actual usage. Furthermore, you're know asking people to trust your "battery test" instead from established websites? Ermmm, no thanks.
[Xperia Z2 General] Envious_Data:
the Xperia NXT series was planned to recieve 4.2.2 but never reieved any updates in the last 5 months of its update contract,

i had an xperia s and about 6 months after sony anounced xperia S was suppose to get ICS, we finaly recieved 6 months after they initially said. i had a Generic unbranded device, so ICS i dont know what was going on, perhaps it was delayed for my region i dont know or care because the firmware for xperia s was always quite slow compared to ICS although being more stable, and even then it was very slow compared to GB although GB having some odd graphics lag in areas where the display layers would go past the set limit, aka the Launcher app

and think is when I'm unsure of something and i was unsure and incorrect, its been about 6 months since i even cared about the Xperia S or any of its siblings so i wouldn't be surprised if i was wrong

and the feeling thing, this device has slow response and higher avg system load when overall compared to any other 4.4.4 Xperia, even the core time response is slower, that loop process bug that plagues almost all 4.4.2 devices has not been patched in then Z2 firmware

and i looked around for quite a bit and a lot of websites claimed they got around 30hrs of life time,

here on xda its quite mixed, some people get about 73 hours and some get 4 hours minimum

on avarage it varies between 14 hours and 22 hours

rom/kernel devs- 23 hours avg

new to xperia- 17hrs avg

everyone else-16hrs

problem threads-11hrs
[Xperia Z2 General] hanciyap:
I email to Sony and made a complaint about the 4.4.4 update to z2. I think we cheated by Sony this time, they can't even give any estimate time or will update the firmware for z2. This is truly disappointed to sony, this will be my last sony product.
[Xperia Z2 General] lee480:
You must be a joke.

1) Did Sony promise 4.4.4 for Xperia Z2?

And you've the guts to use the word "cheated"? You're giving an impression that Sony cheated Xperia Z2 by promising 4.4.4 which is totally false. Hope Sony sues you for defamation.

2) Xperia Z2 is your last phone because of them not updating to 4.4.4? Thank God the world isn't like you.
[Xperia Z2 General] hanciyap:
First, this is none of your business. I just express my experienced with their so called best smartphone in the world. Why you so care about others share about this kind of thing?

2nd, dont be a stupid. My disappointed to sony not truly because of they didnt update z2 to 4.4.4. Others z series already updated to 4.4.4 why except z2? Think about it.

Be mature man, if you dont like this kind of post can just ignore it. No point to attack each other. You can delete my post if you have the right. ;)
[Xperia Z2 General] GretaLewd:
LOL :laugh:

So you post your private business on an international forum :confused: :silly:
[Xperia Z2 General] lee480:
I have only one reply as your other points have no substance.

Maturity? Lol. Joke of the day!!

Making false claims that Sony cheated you? Making childish deceleration that Xperia Z2 will be your last Sony?

How mature LOL.

I heard that mr.Sony Chang XzXz2 was reading XDA forum yesterday and was so sad when he saw some of you are planning to sell their devices that he decided not to sell Z3 but to send not one but two brand new Z3 to everyone who owns Z2...

That's the spirit mr.Sony...

Thank you...

- Z2 Sellers -

:P

Edited :

He just added iPhone 4s on the list as he is also sad to see performance after updating to iOS8 on it..
[Xperia Z2 General] mariosraptor:
Lol. Still waiting for my free Z3.
[Xperia Z2 General] Envious_Data:
Whaaat? How rich is Sir?

Random note Z Someone posted on talk forums and some people are speculating about stuff and thinking Z3 UI may come instead of a 4.4.4 update to the current firmware

Giving 4.4.4 to Z2 shouldent take this long, other devices already have it

Im going to wait at my door patiently like spongebob squarepants once did
[Xperia Z2 General] funky0308:
Hmm...but there's no new UI.

We all saw Z3 UI it's absolutely the same as Z2.

OK, there's some changes but I wouldn't call that new...

Android 5 will bring new UI, this is all just variations.
[Xperia Z2 General] Envious_Data:
I found it to be much more fluid than the current Z2 UI

If you ever used crossbreeder mod on a old device that suffers lack of entropy like an Xperia S then using Z3 feels like the after of using the mod vs Z2 (mod makes new devices lag btw because it was patched in newer linux kernels)

More fluid and response is much higher, device feels snappy

As for UI changes it has small things here and there, icons, few shapes.. Etc

Doesnt apear to have a 2 step boot which means security may not be as good as Z2.. If not then its probably a faster loading 2 step

Some flaps apear to be aluminum, some are plastic

Buttons, metal and meaty

Dont remember much else
[Xperia Z2 General] DrearierJester1:
I noticed other OEMs didnt release 4.4,4 yet on their flagships, G3 (INTL version), S5 (intl) .. HTC had 4.4.3 somehow
[Xperia Z2 General] BR4DOKYBrazil:
After so long without updating, gives me the impression that Sony forgot the Z2!
[Xperia Z2 General] augie7107:
I'm on the Z3 now and it seems much more responsive. New phone placebo or 4.4.4 is that much better?
[Xperia Z2 General] Envious_Data:
It is because there is a bug in 4.4.2 that causes load to rise and it causes the device to slow down

Its a loop process, it just makes lag on all 4.4.2 devices+ the 10,086 other bugs in 4.4.2 that were fixed in 4.4.3
[Xperia Z2 General] shahrulghani:
Oh, wow! I didn't know about this. Thanks for the info. What are the other major bugs in 4.4.2, if you don't mind me asking?
[Xperia Z2 General] Envious_Data:
Alot of base module issue

These affect wifi stability , mobile net reception, camera focal precision

Framework stability, there are tonnes, google changed over 10,000 things to fix thousands of bugs from 4.4.2 to 4.4.3
[Xperia Z2 General] ice_lander:
only we should hope to get it soon ...no news till now
[Xperia Z2 General] Rick Poldo:
Will until the end of the year we'll have some news? :confused:
[Xperia Z2 General] gautampw:
Can you link me to source of info about to this particular bug?
[Xperia Z2 General] Envious_Data:
Android google source code and loads of sites showing thousands of changes from 442 to 443

Here is a link to one of many sites

[Xperia Z2 General] kamalmawa:
Only thing I wanted be fixed is unstable Wi-fi. I have to restart my phone sometime to connect to my wireless network. I heard this was fixed in 4.4.4
[Xperia Z2 General] ice_lander:
Camera is also sh** ,specially when you make photo at dark
[Xperia Z2 General] kamalmawa:
This I can't agree. Z2 actually one of the best camera phone for low light conditions compares to other smartphones and only second to the Nokia Lumia 930 from the comparisons I've seen ;)
[Xperia Z2 General] Envious_Data:
Agreed

Its not bad but its better than most
[Xperia Z2 General] funky0308:
Z2 doesn't have lousy hardware, problem is in firmware and that will be fixed...

I hope Sony has a good reason why Z2 is still waiting 4.4.4 update...

Z3 shows how good camera we have and how polished and rewritten code can improve camera results...

If Sony decide not to share that with Z2 users, we have awesome XDA developers who'll port that from Z3...

They are just waiting for a sources and they will port it :D
[Xperia Z2 General] Envious_Data:
Whats funny is most of the Z2 problems are due 4.4.2 even the camera

There is a odd focal bug that realy ruins the focus precision, if you use cm11 or any 4.4.3+ rom you can see the bug doesnt exist vs 4.4.2

Dont exactly understand why Z2 is waiting on any update even at this point

I HOPE YOUR READING SONY... You will learn from your customers...
[Xperia Z2 General] bdithug:
Lol. Sony barely reads their forums, no chance in hell they'll read XDA :)
[Xperia Z2 General] Rick Poldo:
sad but true :rolleyes:
[Xperia Z2 General] funky0308:
Hehe.. You would be surprised how many Sony, Samsung, HTC and other big manufacturers employees are active on XDA but, yeah, that can't change anything...

Sony must have a reason why we are still waiting....

They updated all devices from Z series and I'm 100% sure they have a good reason why Z2 has to wait..

I talked to one guy who knows a lot of things and he said something smart.

If Sony want someone to buy Z3, that are Z and Z1 users.

So if they wanted to stall so you would buy new device they would do that on those devices.

The reason why they aren't giving update is simple - Z2 will get few interesting features and that's not possible before Z3 is few months on market.

I hope that's correct...

I , personally, ain't buying that...

Just can't believe in something like that.. Why?

Because Sony slapped me once on Z1 (we didn't got nothing from Z2) and it's hard to believe that won't repeat that.

To clear that right away - I don't have anyone in Sony or inside infos.

So, please, don't ask me anything...
[Xperia Z2 General] Envious_Data:
Fair statement

I just wish they would listen

Pleasing customers is always good, but do what the smart techy customers request because they can identify problems more better than anyone whos job it isnt

Aka alot of people who took apart z2 recognised there are no head basins or pipes and also some hardware units are too close together hence the heating problems in general and especialy when using the camera

Never a great idea to put storage unit, cpu, gpu,BUS cable, ram Right next to eachother

In this case GPU, CPU and camera were close with Z2
[Xperia Z2 General] funky0308:
Yeah...totally agree with that but Z2 isn't the only device with overheating problem.

Every other device has same issues.

Some manufacturers added a "trick" to max 4K video to 5min...

I believe Sony did better thing.

Record until your device can record system :D

Apparently, Z3 still suffers from same illness - 4K overheating.
[Xperia Z2 General] Rick Poldo:
I can not understand how older phones that the Z2 already have version 4.4.4, including the Z1. I just find it really strange?

How can the latest top of the line not be upgraded?

We have the latest model from Sony, we are the last to receive the upgrade, if we receive it.

Sorry my bad english
[Xperia Z2 General] Envious_Data:
Sony Can hit about 55 mins max with 4k recording, its been done and proven on youtube and sony talk site....

Its just every device that isnt from that batch cant do more than 39mins max

Sony needs to learn from their mistakes instead of repeating them every 6 months or so to be... They need to fix them or else they will fall out of the market.

Heating problems

Faulty batches

---

Consistent quality

Firmware quality

Better customer sevice, it took 2 months to fix my Z2 :/ thats a long **S time

These are what sony need to focus on fixing NOW!

I am persisting with the hope that they listen to me. Or anyone else in xda, sony mobile keep trying to burry their problems for some odd reason

Sony is fine, sony mobile... not so much..
[Xperia Z2 General] bdithug:
I just called Sony support asking this question. The Rep I spoke to told me that different regions receive updates at different times. I said yes I'm aware of that. He then told me that the z2 has a 4.4.4 update, but not for my region. When I asked what region it's available for, he couldn't tell me. So I asked him when my region (unbranded Canada) will receive it. He said that he will look into it and call me back.

I'm not holding my breathe. I assume it's a run around. But if (and I stress if) there is any truth to what he told me, perhaps a 4.4.4 update is in the works as we speak for certain regions?
[Xperia Z2 General] Envious_Data:
Well sony would be in trouble if they did 4.4.4 only for certain regions, they can have individual builds for certain regions

They probably mentioned 4.4.4 to you to please you as sony customer service did to me a while back with xperia S

They said we was getting 4.2.2 after 4.1.2 and xperia s is still stuck on some slow as can be 4.1.2 firmware

And nothing is certified on ptcrb yet (see attachment)

(323 is a vodaphone update)
[Xperia Z2 General] bdithug:
I'm also betting that's what they did. Like I said, I'm not holding my breath on them calling me back. I'd be shocked unless it's a survey (which I will gladly take and give feedback :))
[Xperia Z2 General] funky0308:
Biggest problem for me, and you mentioned it is inconsistent quality.

That is something I can't believe Sony could ignore...

One device has 2mm gap on top, the other has gap 2mm on the left side...bla..bla..

- Results - bunch of guys who experienced very bad swimming with Z2...

It's ridiculous we are forced to test our luck when Sony is selling Z family as a water-dust resistant/prof.

I have device from 14W18 and even I expected many problems with it (like others) I was lucky..

And that's very lame...you are paying very high price for something you'll maybe get...

Even I really (don't want to say hate...) don't like Apple or iPhone I must admit one thing - they are many miles in front of Android device manufacturers.

Update is global and when you buy device from Apple you know you'll get same device like everyone else...

(I know they have problems as well and don't want to start war here but I would like to see Z3, Z4 and Z119... without those hardware differences and would like to be sure I have waterproof device if I paid for it)

So after all...yeah..Sony, obviously have serious problem(s) and they will have to deal with it.

Results (for Sony) aren't good and they will be even worse if they don't take all that serious.
[Xperia Z2 General] knoxploration:
There are always a few complainers. Plenty of us have perfect phones, and frankly having seen how tight the tolerances are on my phone, I don't believe anybody had a 2mm gap when they received their phone.
[Xperia Z2 General] effective:
Hardly doubt that.Its not even certified.I guess we will wait abit longer. :silly:
[Xperia Z2 General] funky0308:
Of course there's no 2mm gaps on any device, I was trying to make a point...

I never said Z line isn't good or I don't like Z2 - we are just talking about few things that we would like to see in the future...

Not only in Sony devices but on Android in general.

Sony should fix some things, that's something we all know and we all want...

With a Z3 they showed they choose slower update system and they want to polish Z line, mostly in software/firmware part - even we are angry Z3 have some new features Z2 doesn't have - my opinion is that this way could be the right way...

When Z4 or Z5 comes, Sony could have great firmware full of great apps and features with a best look ever.

I really don't think we shouldn't criticise them, why not?

We shouldn't post childish comments like "if they don't change xyx I won't buy another Sony...ever"

That's stupid, I like Sony UI and especialy Sony design (for me Z2 has a better look...but that's just subjective opinion)

When I'm comparing my device to my friends devices (mainly Samsung) all those phones are looking like toys.

UI full of colours, vast settings tabs and "cheap" materials and I would never change my Sony for something like that...

So yeah....for me, Z2 is best device on market at the moment, that's why I bought it but it would be great to see some changes in Sony policy and a way they work...

At least, they could post a few lines and tell ys what's happening and where is our update.

I'm not referring to 4.4.4, I don't care will that be 4.4.2, 4.4.3 or 4.4.4 - I would just like to see update that'll fix few problems we have now...
[Xperia Z2 General] ice_lander:
Dude i changed 3 z2's for one month, 2 of them had those 2mm gaps, uncentered camera, and the first one even cracked itself from the whole panel from up to buttom on the backside without any drops or hits or push, before had Z ,then i also had faulty device ,now i bought that sh** ,thinking that those deffective faults are gone with 3-4 phones released after the Z ,but what i got? Even 3 changes of the device,the last one using it from a 2 months and no probs ,but still when i was at ibiza , beach sand come to the one small gaps and its still there..what can i say ...for the camera i dont want even to think,when i make photos in clubs , they are on pixels ,was same with the Z ,its same with this crap,daylight photos are good,but the night are just awful, 3 years ago i had htc one x ,its miles away phone from Z and Z2 ,but i can upload a pics made in night in clubs, its 3 times better then sony's , like other guys said somewhere up, the hardware its good so again sony didnt do their job well on soft. ,and this 4.4.4 update that ONLY we dont have since Z to Z3, i can say only that isnt Sony anymore,and they arent reliable ,sorry for the bad en.
[Xperia Z2 General] nreuge:
Reading those threads we could believe that all the Z2 are defective! Actually, I believe that concerns only 0.1 % of the Z2 sold or less.

I have a Z2 from the very first batchs, I had a problem with a loose flap that I had changed myself. I won't blame Sony for that, there always some defects in the first batchs, whatever the model, whatever the brand.

I can live without 4.4.4 as long as 4.4.2 is bug free. But this is not the case, the wifi disconnection while bluetooth is on is a very serious and disturbing bug. It should have been fixed for a long time on such a high-end device! I blame Sony only for that.
[Xperia Z2 General] knoxploration:
If you want to make a point, the way to do it is not to make stuff up.

Sounds to me like the common denominator is you. Either you're breaking the phones, or you are obsessively looking for and wildly exaggerating every tiny "problem" you can find, even when it isn't actually a problem.
[Xperia Z2 General] funky0308:
There are many devices with 1-1,5mm gaps or with few mm out of center camera lens..

I tried to be polite, now I saw I shouldn't even try.

There are hardware problems on Z2 and no one can't claim there aren't - If you have good device, you'll have to accept you are not the only one who bought Z2.

I have Sony devices from Xperia line for years and I never saw something like that..

Read forums and see for yourself.

Back glass cracking, waterproof is utopia on some devices, camera lens is few mm, yes, few mm displaced, some devices are overheating not only on 4K play/rec but on simple task like downloading on mobile data and I'm making stuff up?!?

If you are satisfied with your device - that's awesome, I'm happy with my as well but facts are facts.
[Xperia Z2 General] Envious_Data:
These common problems are quite serious, these silly 2mm gaps on 2 of my Z2s caused it to stop working when submerged in water

Alot of people arent exaggerating here, some of these tiny things are serious and alot arent false as your claiming

Ive had 4 Z2s in a row, the camera off set thats not a problem to me but these gaps are because as mentioned 2 of the 4 z2s quit working due to water damage, water damage being dunked in a cup of water

I say kindly now, either dont post, or stop posting a negative comment to a neutral post, if the fact is wrong then correct them but dont call nonsense on something that isnt, i understand the over exaggeration on camera being offset because that its self is not a problem but in terms of quality expected, it shouldent exist
[Xperia Z2 General] funky0308:
If this is right positioned camera then we are all wrong.

Returned device and received new one.

But, obviously, Sony knows less then our smart buddy here.
