I have been looking to purchase the galaxy s 2 for some time now. I've read about alot of problems with the phone but I played with the at&t version and it is super fast, beautiful screen, perfect size and has a great camera. The biggest thing that's keeping me from purchasing it is the audio quality from the headphones. Is it as good as the Iphone 4 or Zune HD(which is my favorite music player) from your experience? Next, hows the battery life compared to the iphone 4 which has great battery life and the only android phone that matched it from my experience was the nexus one. If I do decide to purchase the galaxy s 2, should I get the international version or the at&t version as Im getting them both off-contract. One more question, what kind of 3g speeds are you guys seeing in NYC with the international version and at&t version? Thanks
Now is not the time to get a Galaxy S II in my opinion. Wait for the Prime to come out and either decide on Prime or 4S

My brother just told me that he can get the at&t galaxy s 2 for only $430 so I'll just buy it and if I dont like it, I can sell it for 450-500. I'm really hyped for the prime but I dont know when they are gonna release it and I want to get a new phone over my iphone 4. I dont want the 4S as Im kind of bored by IOS and it was barely an upgrade over the Iphone 4 and I was disappointed, but IOS 5 looks nice.
Wait for prime bro'.
And if I was in New York, I'd sold mine to you.
I recommend you to wait mate, there are some problems with galaxy s2 that still has not been corrected (im running 2.3.4 because i havent got an update few weeks ago greater than that on kies).
The biggest problem with this phone is the retarded overheating, it overheats ALOT when recording at 1080p and playing a decent ammount of games, (i experience overheating issues mostly in 3D games like asphalt 5, Motor Academy, dungeons defenders and more. The overheating issue is a huge downside mainly because it cannot let you enjoy your game without feeling that boiling effect on your fingers and the fact that i worry most of the times for it to not melt the circuitry board inside, like it has happened before with other people (ive only read 1 guy having this problem so far).
But there are also other problems, the oled screen still blurrs, its faster than an lcd but blurr is still there, viewing angles shifts hue to a bit of blue, if u put solid colors like pure gray on whole screen, you will notice the color displays with a different contrast on different parts of screen, the camera displays a pink circle on the screen when in medium lighting conditions viewing white walls or other objects that occupies the whole screen.
Speaker quality is average, there might be more but i cant remember them right now.
This is the best phone i know right now but i recommend you to wait for a better one, hopefully without these problems, if u cant wait and rly like oled then this might be the best one so far.

WHAT? Dude if you have all those problems then you should return your device and get a replacement because i got none of them. This phone is seriously phone of the year and this is my first samsung device. If sammy keeps this up then i am in for good. And about screen getting real hot... I got that problem in the first weeks but then after an update the problem went away. Using lates villainrom now. But like every other dual-core smartphones the phone gets hot when you use it for a long time... Again this happens to every dual-core smartphones as the cpu uses alot of power. And to the op, I seriously recommend you to get this device, unless you're thinking about getting the prime then you should wait a few more weeks. But i dont think that the prime will be much better then SGS2 except better screen.
Umm i don't think you can call it overheating for the sgs 2. In the sense that it is not overheating, it is simply expending the amount of heat proportionate to the amount of work being done. it's like when you play crisis 2 on your computer, your computer gets really hot right? Well an average computer per say, not a prepped, or modded one.
So like the computer, the sgs 2 is bound to heat up since you are forcing it to perform at such high levels, meaning big 3d games, 1080p, etc. To summarize, with great power comes great heat.
Which brings me to another speculation, how bad will the prime or iphone4s heat up? if the Mali does this bad, I'm wondering how the sgx543 will do since it has atleast twice the performance.
Anyways onto your own matter, I'd rather wait than get a half year old device despite the enormous pros.
The SGS2 is kinda cheap now, and it will be even cheaper when the Prime will be out. This phone has good specs, it won't grow old that fast, so i wouldn't go mental for whatever comes next. Anyway, i'd wait a little if i were you

Well then, im not sure what u call melting the circuitry board, but i call it overheating.
as for whoever told me that i should change the phone because someone else got none of those issues, i had changed it 2 times and all 3 i had, had the exact same problems, you probably dont get overheating because you either dont use it for the same apps or games as i do or u have possibly underclocked it or have some sort of battery saving application, or maybe even an unnoficiall firmware, these problems are part of all s2 phones it has been checked plenty of times by plenty of experienced people in this forum, they are nothing new.
PS: i doubt iphone will have such issues, maybe their battery will explode again or maybe it will loose signal if holded with left hand, but i doubt itll have overheating issues, there are some dual cores out there and none have such issue as sgs2 has, it has nothing to do with it beying stressed to much, its either a hardware building fault or a software issue.
The S2 is pure gold still when Prime is out, the phone got no problem at all IF and only IF you follow the root instructions/rom installation instructions step by step, if you forget something, you probably end up with problems. (most forgotten is to install kies drivers or to not shut down kies while flashing with odin).
Prime is gonna be the top phone, so it can be worth wait.. but sure the S2 (2nd best phone by then) will cost about 200 less.
I bought the SC2 right after the iPhone 4s was announced, not regreting, and don't think the the prime will be much better, I probably buy the s3 when it comes out next year.

Buddy just go for the phone that YOU want...Galaxy S2 is for me a top top phone..dual core gorgeous screen and memory is great....regarding audio i cant find any faults with it..you have different equalizer settings and you can adjust it to your liking....
regarding the overheating issues i have occured them as well when i first got my phone....since ihave rooted it though and have got my custom rom and kernel that i am using that has gone away now and im experiencing great battery life....like the post above the next handset for me will be the s3....
iphone 4s if the screen was a tad bigger i would of gone for that....but as i said if you cant wait for the prime then s2 is the one for you buddy

Well overheating for me means it is expending so much heat whilst doing so little. Meaning it is heating up even though it is on standby or screen off.
Melting the circuit board I think is natural if you expect it to handle so much. Because when the GPU or processor demands so much power/electricity in proportional to the process, and the process is a big one, then of course it will need a lot of power. And where does the power go? Well the wasted becomes heat. And personally i don't think you can compare other past dual cores as none are nearly as good in architecture as the exynos or in fact perform as close, side from the A5.
And yes I do experience great heat when I play games like dead space, dungeon defenders, and so on. But i expect it since the phone is trying its utmost best to perform. Meaning it is trying its best to play at 60fps or more when it isn't needed. Now a solution maybe to cap the GPU and CPU to only produce frames at say 24fps or so. That may fix "overheating".
Note however that above is sincerely speculation as i have no idea how the SoC operates.
My personal experience after 4 weeks with the S2:
It´s great as a fast multimedia device (great images from Camera, HD Video recording and playback of movies and films, internet browsing), but if you plan to use it MUCH as a phone stay away... speaker quality is quite poor, you may experience trouble with echoes due to failing noise redcution, volume with headset is very low.
Other MAJOR downsides i found, compared to other droid phones:
Wlan signal strength very poor, around 20% lower signal rates that LG Optimus. Also 3G signal strenth is poorer than LG. Really disappointing.
AMOLED display is overrated, colors of images are distorted and very unnatural (reds, blues) compared to standard LCD (i´m a photographer so i know how my images should look).
Ob btw,if you plan to use the S2 as a GPS car navigation device forget it, because the battery will be charged at a max rate of 650 mAH even if your car charger can deliver more - at least with Navigon your battery will drop even when charging! What a joke!
Long story short: don´t buy unless you can get it for under 200 USD.
Nexus Prime. Simple.
Or Nokia WP7 if you can wait.
wait for primee buddy, i'd do it
Might wanna look at this phone. Its has all the latest technology packed into a sexy slim stylish design.

You're on to something there!
- Also useful for hand to hand combat.
- privacy, no one will be trying to snoop a look at your screen.
- outdoor hobby requirements, you'll never be afraid of doing an army assault course knee deep in mud with it in your pocket.
My sgs2 , while good, isn't great at meeting the above points.
Go with what agrees with you.

Yea I read somewhere it can be used as a baseball bat too. I wish my gs2 could do that . I loose count the amount of times I've left mine at home while out shopping and I've spotted some chavs.
I belive that the nexus Prime will be on pair wih the Galaxy S2
Hey,
I was consider to get the HTC One M8 but then I came across the Sony Xperia Z2. I was looking at the feature set of both. I went and got a feel of both the devices. My only real concern that came about would be the development aspect of the Z2. I love to tweak around with my phones.
The other issue that hit me is the speakers on the Z2. I havent had a chance to play with the Z2 in the sound department but I did have a chance with the HTC One M8. Does the speakers feel good to listen to?
Any thoughts would be helpful
Well opinion wise on the Z2 , the speakers arent perfect but thats because of the fact the phone is waterproof, everything else is amazing
Development has started slow for Z2 alike most xperias, give it a couple months for it too speed up, we already have official CM11 and TWRP, there should be more to come
And not to mention all mods for 4.4 will most likely work on other xperias
(this does disinclude kernels and roms)
Sent from my D6503 using XDA Premium 4 mobile app
I have both devices i think that the M8 is better in design and the sound quality is better both speakers and earplugs wise.
The camera on the Z2 is waaaaaaayyy better then the M8 and i personally think that the system ui is better as well i am not a fan of sense it just to heavy.
And custom development always takes a tad longer on sony devices. I've had both devices and i'm still not sure which one is better .....:silly:
i have z2 and love it. Overall i feel m8 is great but z2 has a slight edge in all departments other than sound. Sound is awesome on z2 but m8 is better.
Sent From My Nexus 5 Stock 4.4.3 ART
If you want a single device for all your needs go for Z2.
Want only a smartphone and have a separate professional camera? Go for M8.
Here's a comparison video :
https://www.youtube.com/watch?v=dKCgqeVdZ3w
Well as far as I see. The sony xperia has a pretty gud feature set. I know the development is a wee bit slow. But considering the fact, I think I just might go for the Z2.
I haven't got a chance to play with M8 but I have had M7 for 5 days before I decided to sell it and married Sony Z2.
Originally, I came from Apple 5s and to be honest the camera on HTC One M7 was horrible. I went out for a persimmon picking trip and I took my brandnew HTC M7 for photo shooting and I was shocked by the photo quality, blueish, dark, blrury and incorrect colour. Even my gf was shocked with my new toy's camera performance. Overall HTC was a good phone, sleek design, study and iron cold feeling, nice and sharp screen and beautiful UI. But after I sold my HTC M7 and bought the Sony Z2 and I must say it is one of the best phone I have even owned. Fast, beautiful scree large screen, simpe UI and super long lasting battery. I am a heavy user and apple 5s could not keep up with me as long as Sony Z2. Anyway, from Apply 5S -> HTC M7 -> Sony Z2, I am really happy to stay with Sony for a long time. And it is my first Sony device I have ever used since I was born ...lol
Hey all, I have the same dillema.
I have just sold my Note 3 and want something smaller and with a capable camera, very good sound quality on speakerphone while on skype and normal calls.
In the last aspect my previous HTC M7 was the best however it's camera was unacceptable, especially in very bright sun light...
To be honest I don't know why I am even considering the M8 because of the camera, but I guess I have the sentiment for the previous one.
Anyway, my biggest concern with Z2 is overheating. I went to Vodafone shop and turned on the Camera app to see how the phone behaves. Within 1-2 minutes it got noticably warm, just because the screen and app was on...
How widespread do you think the overheating problem is? Logically speaking, if something is sealed very well for water not getting in, than it must be not so great with heat dissapation... Unless it is made of aluminum...
I don't want a camera phone having a camera which I cannot use because of overheating...
Also, is it difficult to flash stock firmware over branded one, with sim lock present? Does the phone need to be unlocked?

The one you tried in vodafone store was probably on for whole day i.e., screen, speaker, demo... therefore it was already hot prior your camera shooting trial. I have no problem with my device. Trust me HTC M7 heat problem is a lot worse due to its metal case. Sony used combine materials including plastic, glass and aluminum therefore heat is not as bad as metal housing in general.
Worst case scenario, it is waterproof so just give it a shower, will help to reduce heat issue
Feels like I might just get the Z2. Ijust have the issue of the dev community for the device. Since its a new device, I have a feeling that the dev community will be strong but that we shall see.
Plus me getting the Z2 depends on my stupid carrier keeping it in stock xD. They released the device here and with 2 days all the carriers ran out of stock. So lets hope I get my hands one xD
I think I answered this question to myself...
Until Sony fixes the overheating problem (provided it can be addressed through software and it is not the hardware at fault), I will not get this phone.
I went to Vodafone Ireland store close by and put the phone to test. I started the camera app and launched 4k video and left it going, while I was playing with HTC M8 and Galaxy S5 (ugly phone and the same design all over again...)...
Well, after around 5 minutes I got the overheating message... Keep in mind when I started playing with the phone it was cold (no one playing with it, screen off)... The temperature now is around 20-22 idle.
Ok, I thought, It can be forgiven as I do not give a damn about 4k... So after it crashed and took me to the screen, I opened photo app again and managed to take 4 pictures before I got the message again and when the app force closed... After 10 seconds I did the same and the same story...
All I managed was to laugh out loud, while playing with the HTC camera and having its chasis still cold, and I just left the store...
Those temperatures cannot be good for any internals inside, especially the battery. I can bet Z2 users will have their batteries deteriorated significantly by the end of this year, if they use it as GPS nav, gaming devices or... Just as a camera...
RIDICULOUS... But I guess I will be tracking the forums and see if any of the firmwares fixes the problem, if not, I will wait patiently for Q3 phones this year as there is nothing that ticks my boxes at the moment.
Thanks.

Camera is set to shutdown at 65c cpu temp, which is nothing in todays technology. So no, it wont affect battery or something else. Also what do you expect, you make 4k recording, turn temperatures to hell and then take pictures, outcome clear to me. If you start by taking pictures that wont happen. And m8 is not a factor here, its probably imposible to make any smartphone overheat by taking 4mpixel photos lol.

No offence here but really you buy a smartphone just to shoot 4K?
So I just got my z2. YAY!!!!
Sad part is that I didn't get the noise cancelling ear buds. #WelcomeToTheMiddleEast
On the other hand. I just love the feel of the device. It just feels right. The aluminum and glass feel just perfect. It's feels a bit more premium than the M8 imo.
Problems. The device heats up. But tbh I live in a hot country so it really doesn't matter XD. The heat is more towards the top part and the device just heated up when I cranked the brightness high and started recording 4k video(Which I doubt I shall ever use in the near future)
Now all I got to do is get a case and a screen protector so that I don't destroy it in my rough daily use
Hope my short review helped anyone

Can you do a test for me, please?
Could you actively use the phone for a while (say 3g browsing or wifi) so that it becomes warm at the back, and once it gets warm, can you open the camera app and try to record 3-5 minute hd video or take at least 10 pictures in the row?
I am wondering if you get the warning message.
I just sold my M8 and ordered the Z2, I'm excited, I hope it was worth it!

Okay so I tried that. And nothing much happened. It just got a bit hot. like it wasnt that hot. Keep in mind I tried this indoors when the air-conditioning was on was thats something.
I live in a hot country where temperatures can reach 40+ Celsius or 100+ Fahrenheit but still I dont find the phone to be that hot. It does become hot ever so slightly but thats expected.
Hope I helped you out.

I was inclined to the M8 in the beginning but now I feel this device is better in terms of hardware as compared to Sony.
Development is real slow but thats expect from Sony devices. As far as stock goes, Its not bad but can definitely be improved. Sony actually did a really amazing job with the software.
Believe me you will love the Z2

That is the thing, the phone is not expected to get hot when doing not so really intensive tasks like browsing, downloading, or recording hd video/taking pictures... I had Galaxy S 1, 2, HTC One, Note 3, played with M8, Galaxy S5 and those phones only get "warm" when sat nav or comparable heavy task...
If your phone gets very warm at home with AC on, than what do you expect will happen when you try to use it outside at 35 degrees in your country?
Nothing like this would happen with any other competition's phone, seriously... It must be a design flaw, those problems were present with previous Z's as well if my memory serves me right.
No, I don't care about 4k video recording, I would survive this overheating problem if the phone overheated only in this case, but overheating when taking pictures after doing some light intensive tasks? Unacceptable...
I am pretty certain it can survive for a long time. The thing that gets hot is the glass not the metal frame. And when it's hot it's not hot as in u touch and u r gonna burn yourself.

Hello everyone.
I bought my Z2 from Amazon.com. So, As you know, We can replace the phones in 30 days.
I'm in USA for now. And I'll return my hometown after 25 days later from now on.
Here is my problem:
I bought the Z2, and I was aware of that issues that "Heating, Gap between speaker, self-cracking issues etc". But Still, I bought It because I listened my heart and the Z2 the is best phone btw.
The Problem that is blows my mind : The Over-Heating. I'm not talking about the "4K Recording over heating" I know that I have this issue and I don't care about this.1080p is still good.
The thing that I care about, the phone is getting warmer after using 10-15 minutes.
For example; I tested In room temperature, 20-25 C, I've played the game "Hungry Shark" about 10 minutes. Phone got warmed but it's acceptable. After 5 minutes more, It was like I heated the phone under sun and I don't like that.
Even in browsing, Facebook, whatsapp, or other applications, my phone gets warmer too quickly. And while charging, even without using my phone, It gets warmer a little bit.
Anyone who has the same issue or this is really normal ? Should I go for a replacement?
Because I've upgraded z2 from my retired Desire HD and It never get that much warmer.
I appreciated. Thanks.
I'd day that's completely fine. My Z2 heats up quite easily to. Battery is atm 38 degrees and I'm only on WiFi and using XDA app. Glass conducts heat much worse than for example metal (or so I think ). Also since the phone is waterproof and thus sealed it heats up more easily. I doubt that you have to worry about the heat, unless the phone gets really uncomfortable to hold. If it gets too hot it will throttle down and ultimately shut down to prevent it from getting damaged.

Glass is an insulator, metal is a conductor other than that +1.
Please bear in mind you've upgraded from a 1ghz single core CPU to a quad core monster, I'd be astounded if it wasn't getting appreciably hotter.
Its gonna make a very high tech hand warmer in winter time, thats a bonus

Battery is atm 38 degrees and I'm only on WiFi and using XDA app. Glass conducts heat much worse than for example metal (or so I think ).

I really appreciated your answer. I hope that it is true that there is some kind of "over-heat protection" or something. But still I'm thinking about it because many other phones, I mean LG G3, they don't have such kind of issue.I mean I've never heard about such kind of thing on forums.
I don't want to say goodbye to my Z2 because I really love the feeling of it. But I have to decide before I returned back to my hometown.After that, it'll be impossible to get a replacement. I want to emphasise that after 4 years, I upgraded my phone and I'm not that kind of person who changes his phone after using it 6 months .
I want to use that phone like for a long time. And something brand-new which is overheating... Makes me think.
Thank you for other answers, and that bonus feauture make me laugh
So, Any other answers from Z2 users ?
I thought u can only return your phone within 30 days if it hasn't been used?. Are u after a replacement or refund?. I got mine from amazon uk, and also have heating issues. My 6yr old always complains it gets to hot when he plays games, never had that issue with my 5s.

You can return your phone in 30 days. That's what's written in return policy.
I don't know what I'm after at.I couldn't decide what to do. But it seems that everybody has that issue.It's quite easy to heat Z2.
I've got mine from amazon .com. But the good news is that I bought a case for my handset and at least I don't feel the heat so much.
Btw, What is your batch number? Could you check yours ?
Mine is 14w28.

The G3 has overheating problems. My G3 idles at 55degC and during gaming It got very,very hot. It also dropped frames during gaming due to the thermal throttling.
In comparison my Z2 is cool.
I've not had this issue with my z2. It maybe because I don't play games and its winter but general browsing and string HD over LTE only make KT slightly warm. And obviously it only gets warm towards the top where I expected the processor to be. People shouldn't expect processors to stay warm. Even the latest Intel processor can idle at 30 bit the minute you put stress on it, its gonna jump several degrees. This should be a given for any processor

I'm pretty sure you can only return it in a unused condition.
Hello, im thinking of buying a z2 , but i read about the self cracking screen, that happens a lot? .
Myth
Ive had a Z2 since it came out and quite many have reported they HAVENT had this
Some of the pictures taken of a "self crack" have shown impact areas where as a few "self cracking" posts were true but that was down to Quality control issues

First time that I heard that.
You should buy Z2,its just a some false story.
At the beginning of Android 5.0 the phone was able to heat like hell if the app was using lots of CPU.
I cracked my BACK of the phone this year in January (or was it in February?) while it was f*****ng cold outside and I used Osmand.
Osmand likes to heat your phone anyways, but these early Lollipop days added extra heating due to the rom, especially I was on some CM-rom...
But as I said, this was like -5 degree cold and windy outside, the phone heating at +60 or so... And then the glass-back cracked...
I didn't even bother to replace it, works just fine with the crack
Not so bad. You can try
Hi, I have a Z3C and the problem is that my touchscreen now is busted, though I can still use it by rotating the screen.
It started on the upper extremities of the LCD, I became annoyed and tried the "lighter fix" for LG G2, which didn't work great for me. Touchscreen got way worse, wtf am i expecting applying 3k volts of static electricity.
I'm torn between replacing the screen or getting a z5c instead. Though my z3c somewhat slows down now, it is still usable and OK for me.
I know that if i replace my LCD, it will not be as good as before, so I'm thinking about that.
And if I get a z5c, i don't know the little issues, or if they were resolved with .11 update. Even small physical build issues concern me and I can't find a comprehensive list of issues. Also, screen replacement will cost me just around 20% of a new z5c unit, or maybe i could get a 2nd hand one.
Please share your thoughts, should I go for z5c? Or other brands (around 4.7 inches also)? Or screen replacement?
Thanks!

I dont really know how did you get to a conclution on little bugs of z5c? has no bugs whatso ever , in fact go watch youtube videos about it , most of the known youtubers like linus concider the Z5C the best compact phone out there ...
also replacing a screen in its own manufacture is not wrong or bad and they wouldnt put a bad screen or "not as good" I could be wrong , but I already replaced my older phone Z2 screen twice and I didnt see any difference...

Well every phone out there has issues, some of them can be found only with everyday use. I've heard overheating, screen self crack and bad battery performance for z5c. But overheating and bad battery performance can be fixed with software, but not the screen cracking.. I think you get the point. Those little quirks.
About the LCD replacement, most of those comes from china. And I've seen so many issues with friends with replacement screens (non-OEM). This ranges from low brightness, touch responsiveness, bad color reproduction to flat-out touch failure in 3 weeks after installment. Yeah, so I'm quite worried about that since technicians will have different prices for "replacement", "class A" and "original" (original but not OEM, wtf).

I dont know how it works in your country ( I dont know where youre from either lol) if you send your phone to its original manufacture in your own country and pay them lots of money to fix it they should install original and if its not like that then buy the z5c if you want , seriously check youtube videos about it from well known youtubers its the best besides some times over heating in high level of usage (like gaming etc...)
I believe there to be a serious component issue with the touchscreen panel of the Z3C, "gate" level serious. There's way too high a percentage of people reporting touchscreens that die right after the 1 year mark, just out of warranty. Getting a replacement just means that it will most likely die again after a year or so, because it's the same faulty component, and (at least here in my country) they don't guarantee waterproofing after repairs which is really unacceptable after asking for around $130 in repair fees. Not to mention that it's obviously a flaw with Sony hardware, but they deny it and refuses to take responsibility, so the cost of repair is passed on to the victims, us.
Coming from Z3C, you will find the battery life of the Z5C disappointing, even with moderate to light use. Then there's the problem of the POS S810, so the phone is constantly throttling and overheating. It's really a shame, because I otherwise think the gorgeous design of the Z5C is the pinnacle of the Omnibalance language. There are real noticeable improvements to many of the small quirks I had with my Z3C, like the overly rounded edges that eats into my fingers with prolonged handling, non-exposed USB port, dual speaker cutouts that are really dust holders (Z5C elegantly placed them at the edges)... etc. Whether the trade-offs are worth it are based on your personal usage habits and wish list.

Though i'm turned off by the larger besel of z5c
Also, there is no magnetic charging which should be a main selling point IMHO.
But is the throttling and overheating solved by the update or custom rom? Pls link me to the POS S810 issue, i dont know what that is.

Larger bezel? Do you mean the slightly more disproportionate top and bottom bezels due to the lower screen placement compared to the Z3C? Because both are literally the same in screen size with nearly identical length and width dimensions.
http://www.phonearena.com/phones/size/Sony-Xperia-Z3-Compact,Sony-Xperia-Z5-Compact/phones/8744,9611
I've been using the Z5C for 8 months, and I've never been bothered by or noticed the display being lower. And that's coming from more than a year of use of Z3C, and the Z1C before that, which were both more symmetrical.
Initially I was also disappointed with the exclusion of the magnetic port, but only a few weeks in and I haven't missed it since. Having the exposed USB port at the center bottom really helps, and I favor having a seamless edge that again doesn't eat into my skin over the convenience of a charging port that only sees use when I'm not using the phone, which as I mentioned is rendered moot by the ease of access of the USB port. I bought a DK-52 dock for charging and never had problems docking it with ease, although I had imagined it would be problematic.
As for "POS S810", I mean "piece of **** Snapdragon 810" SoC. See here: http://arstechnica.com/gadgets/2015/04/in-depth-with-the-snapdragon-810s-heat-problems/
Or you can Google around "snapdragon 810 overheat", in short this silicon is ****. Sony's done their best (arguably the best out of all manufacturers) to mitigate the impact, but in the end there's only so much you can do to workaround an inherently poor hardware design.
*EDIT BELOW*
As for the question of throttling and overheating solved by updates, there doesn't seem to be a decisive or conclusive evidence of that. With each new update, it seems there's always people reporting better battery/improved thermal alongside people saying it's worse or no change. Yes, there are mods/ROMs claiming to fix the battery and heat issues, whether or not they actually make a difference is more of a personal usage thing, you have to try them out for yourself and see if they work for you.
It may sound like I'm hating on the Z5C, but on the contrary I actually love my Z5C. It's just that after using the Z3C, high expectations have been set but the Z5C failed to deliver on some accounts, mainly the battery and thermal issues. Otherwise, I genuinely felt it was a worthy upgrade over the Z3C. I've come to accept that I won't be getting the same outstanding battery performance of the Z3C, but that's not to say that it isn't great on its own merits. Also consider that the Z3 series are pretty much dead since they're not getting official Android 7.0 support, while the Z5 series are still on the upgrade list, albeit now at the lowest priority compared to the more recent models.
So to sum it up, I don't think it's worth investing in a screen replacement that may still break after a year, not to mention potentially losing the waterproofing. The Z5C may be the next logical step after the Z3C, but has problems of its own. You need to decide if the drawbacks are worth it. At least it's been a little over a year since the phone's release, and there seems to be no (mass) reports of dying touchscreens. Yet. So it's got that going for it, which is something I suppose.
This phone is still very good despite its few hiccups. It over heats when shooting long videos or playing graphic-heavy games (many phones will over heat too), i dont know z3c battery life but with my z5 i get minimum 5rs sot wen browsing the web, minimum 4hrs when playing plants vs zombies heroes, minimum 4hrs streaming videos, on light useage i get minimum 2days... Remember i say minimum.
The camera is not great on low light conditions but it is superb in daylight. Its performance is snappy, water resistance is not a gimmick, speaker volume is loud enough although i was not impressed with headphone volume n sound until i installed another app.
The phone is worth it, not perfect though.

OK, I'm getting a Z5C tomorrow LOL. What I'm saying about the bezels is that the large bezel at the top is turning me off somewhat (I think z3c has the perfect size), but that is just me nit-picking on stuff, it doesn't really matter on daily use.
About the USB port, I'm just scared of it physically breaking, or just being lose or having bad metal contact. I had this problem before so I'm kinda always worried about ports which are like usb. On the other hand, the magnetic charging just holds the cable and the phone with a magnet, so I don't need to worry that I may damage it when someone accidentally applies force the wrong way to the cable/phone. BTW I did not use the dock on Z3C, just some cheap magnetic cable. Anyway that is fine I can live without it.
Another thing, I read in gsmarena that the usb port has a waterproof coating so that it can be submerged in water? Got any more info on that? Just curious here.
BTW my Z3C now is not water-proof anymore since I went full retard (I squeezed the phone while under water, destroyed the mic, so I got it fixed).

I think heating when using phone (games, browser, video) is normal. Is that is what supposed to be the overheating issue? My z3c heats up when using chrome too, and that is fine with me. What is not fine is like when I'm just reading an ebook or just calling then it heats like crazy. I just use my phone for texts, calls, ebook, RSS feeds, some browsing.
Camera is also fine with me, I'm not really a picture-everywhere guy, I rarely use it so its just a plus =).
The exposed USB port is waterproof, that's the great thing about it. Just don't use it while under water or after it's been submerged in water, you still need to let it dry out. So with the Z5C, unless you're frequently changing SIM or microSD cards, the only flap will stay closed for like 99% of its lifetime and the chance of it being water damaged due to the flap becoming worn and torn or improperly closed is minimal.
All phones get warm when you're executing high load tasks, but it can get borderline melting with S810 phones. Seriously, in certain situations it can get really uncomfortable to hold, no to mention there's the throttling to prevent it from self destructing, so you'd also be experiencing degraded performance while handling a hot brick. It won't happen with casual phone calls, browsing, texting, snapping a photo or two... but if you're doing intensive stuff like playing heavily encoded videos or resource hungry games, you'll feel the heat and see some stuttering thanks to the throttling. A personal experience, I once tried viewing an anime in 1080p that's probably encoded with advanced codecs on my Z5C, after a few minutes it starting burning my hands and became unwatchable, lagging like crazy. No doubt it's because the decoder and real time down-scaling of the resolution to 720p needed full processing power.
With your usage though, you will probably rarely experience it. Might get lucky if you loaded up a poorly optimized rich media website or something, but not likely.
A new z3c is.the best option. Z5c lags a lot because of 810.
I got my z5c.
Z3C looks a lot more better aesthetically. But, oh well, thanks for the replies!

I'll agree with that. The Z5C's slightly bigger top bezel does bug me, or at least did when I still had my Z3C and could see them side-by-side. It's also slightly more boring looking than the Z3C. Other than that, though, I think the Z5C is far more comfortable to hold than the Z3C, and I haven't noticed mine lagging any more than the Z3C did. After flashing the X Compact's camera APK, the camera is also far more responsive, which is great when you have two little kids around like I do.
Same thing happened to my z3 compact and I replaced the digitizer/lcd myself with a kit. No problems except that months later, the screen started peeling up because of the stickers not holding fast. Finally decided to order an X Compact and returned it immediately. Just didn't like the look/feel.
I didn't want to buy another z3c so I purchased a z5c off of swappa. So far, I'm very happy with it. Still waiting to see how it does on battery life but the phone is beautiful. IMO, the best reason to upgrade from the z3c is the fingerprint scanner.
Damn!!!! I have the same problem with the z3c screen, and the same concerns: should i fix it or should i upgrade (of course to z5c, the only one who seems comparable)?
I have not decided yet... I really love my z3c
@ wakoko79 : what are your impressions of your new device? Especially battery and heat/lag.
Thanks

Agreed. I previously owned a Z5C. I hated how much it heated doing simple tasks (browsing internet, updating apps, ...) they didn't need to be CPU intensive to get hot. I always felt a little uneasy that the heat would cause a battery failure if I let it get hot enough since the heat would run down the back side of the battery. It wouldn't be terribly hot but it was hotter than a phone should get. I then purchased an XC which has a "comparatively" powerful CPU and that thing barely ever gets warm and it has yet to get as hot as my Z5C did just updating 3 apps in a row.
I would have suggested an XC but the Z5C did well when using it. Congrats, I hope the Z5C roms can get that non-stock Camera figured out.
z3 was a great phone. i owned one but was broken so i upgraded. z5 c is similar but is a little faster to me. the camera options are improved and the z5c camera is better both front and back. Plus the z5c is 32g internal vs the z3c which is 16. z5c also has a finger print scanner that works great. z5c updates are going to be better than the z3c in my opinion. z5c gets warm but it's never really bothered me especially with a case.
z5c is hands down better.
