The overheating problem with 4k video has greatly improved with software updates. Not so much an issue now. The build quality issues are never general. Luck of the draw I suppose!

The z2's got the best overall specifications on your list of devices. It's a great phone with no weaknesses side from the auto mode of the camera. Learn to use manual controls and you'll soon lose the impression that the 5S has a better camera.

Considering that is the cheapest on your list, I'd say it's a no brainier. Best phone, cheapest price! What more could you ask for. You have Sony's insane 6 month cycle policy to thank for being able to buy the z2 at such a price.

Trust me, in no way are any of the other devices on your list worth more than the z2.

That's One thing to bear in mind though when purchasing Sony devices. They don't hold their value for very long because of the rate at which Sony releases flagship phones so don't expect good resale prices should you decide to sell it on one day.

So if the rapid devaluation in value isn't an issue for you, the z2 is the one and only real choice you have. Unless, that is, you want to settle for less and pay more for the privilege lol
[Xperia Z2 General] kylecummins:
As far as i can tell, ive owned two z2s... The self cracking is an earlier build issue.

My 2nd one has had no issues.

Also after some fighting with sony and getting the better business bureau involved sony fixed the first one at no cost.
[Xperia Z2 General] ghostofcain:
Self cracking is an issue for a small, but vocal, minority so can be ignored. overheating similarly isn't an issue for most users in normal usage, sure Z2 gets warm but what superphone doesn't only real issue is if you want to record long videos in 4k,which if you bear in mind most phones are limited to 4 minutes is a problem whatever device you get. Z3 compact will likely be more prone to overheating, much the same hardware in a smaller package.

As for iPhone 6,if it fits your criteria and you can live with its closed environment go with it, an android device probably isn't for you anyway.

What makes you think android devices are not for me?
[Xperia Z2 General] matase:
I just found out about this phone and I am in a similar situation as the OP.

I am looking for a used/new phone for less than $500 dollars, has an above average camera, good battery life, and no lag issues.

Currently, I am using HTC one m7. A few problems with it is that a camera is super slow and crappy at low light situations. The camera takes like 1-2 seconds to focus on the subjects in dark environments. Next, the phone lags and hiccups quite a bit. I've tried a few custom roms but the performance is still not flawless.

In the past, I have owned an iPhone 5 and it was great except I got tired of the OS, that's why I went back to android. iPhone took best pictures in my opinion. The camera was fast. The phone did not have any hiccups. One big thing I noticed going from iPhone to HTC was that songs don't skip as fast as on the iPhone. It takes a split second more for songs to skip in an HTC music player. It kinda took time to get used to it again. I would consider getting the iPhone 6, but it is too expensive.

I am also considering oneplus one, m8, and maybe moto x or nexus 5. But overall, I think z2 is the best all-round performer.
[Xperia Z2 General] ghostofcain:
With iPhone everything is designed to just work, if it doesn't tough ****. Android, still IMHO, lacks the polish but there are almost always work around to any major issues.

In my experience the people willing to work around androids foibles find the locked down world of iOS too constrained, and those who put up with those constraints find the fiddling with android to get it set up to their liking too much. But that's just my take on it.
[Xperia Z2 General] Jiyeon90:
I was kinda skeptical too after reading about all those Issues but still bought the Z2 1 month ago and I couldn't be happier.

No heating issues, no call issues, no cracking glass (so far)

Everything works flawlessly ?

Self-cracking is not a thing. If it was, you'd be seeing the forum flooded with complaints, not just a handful of people moaning.

Those claiming self-cracking most likely damaged it themselves through abuse, possibly knowingly, or possibly not.

[Galaxy Note 3 Q&A, Help & Troubleshooting] sanjay41:
I purchased a Samsung note 3 from Manila , Philippines. It is worked well with local SIM at Manila and it is also working fine with local SIM at India. However, it is not getting updated to KITKAT, though it download the update but not been able to install it perhaps due to Knox. Any solution? It would be a great help.
[Galaxy Note 3 Q&A, Help & Troubleshooting] vndnguyen:
Try update yourself instead, using Odin.

Install Phone INFO ★Samsung★ app > Menu > 'Firmware Browser' to download the latest firmware for your device.
[Galaxy Note 4 General] CLShortFuse:
After being disappointed with a locked bootloader on my AT&T Note 3, I decided to not make the same mistake again. With Android L coming out with 64bit CPU support and with 20nm die size it looks Exynos is the winner. Yes, Snapdragon was more popular before, but I'm pretty sure 64bit will be the hot topic with Note 4 development.

So what you came here to see. I found this wiki page detailing all the bands and processor information for different devices:

http://ko.m.wikipedia.org/wiki/삼성_갤럭시_노트_4

It shows bands 4 and 17 (among others). Now, that wasn't enough proof for me so I started searching some more and got the FCC data for N910C.

https://apps.fcc.gov/oetcf/eas/reports/ViewExhibitReport.cfm?mode=Exhibits&RequestTimeout=500&calledFromFrame=N&application_id=544347&fcc_id=A3LSMN910C

You can check out LTE Test Reports 1 and 2. It shows LTE bands 2, 4, 5, 17 on the first report. The second is just more technical data.

I didn't see anything about band 12. Sorry T-Mobile users.

If anybody finds any information about purchasing one, please share.
[Galaxy Note 4 General] arjun90:
Many state the 910F is the most versatile worldwide (for LTE, etc.), but the 910C may also be on my radar if this is the case.

Just remember that the SD805 will be getting the most attention in terms of development since most owners out there will be having a Snapdragon device.
[Galaxy Note 4 General] CLShortFuse:
According to the wiki page the F and C both support the same exact bands. The difference is the F is Qualcomm based technologies.
[Galaxy Note 4 General] cmd512:
LTE on Exynos for AT&T in the US has been a sticking point for me, I will be following this thread with great interest, thanks.
[Galaxy Note 4 General] Lodix:
Why don't just go for N910U ?
[Galaxy Note 4 General] arjun90:
I haven't came across much info regarding the C model. However, if the C model is released in Europe that would be a plus for me. Besides Wiki and FCC, are there any official sources for the C-variant containing Exynos?

Also seems like the FCC weren't testing the official device at the time as the tests were conducting in early Summer. Um....
[Galaxy Note 4 General] CLShortFuse:
No support for band 17 (700mhz).

It's prety well-known by benchmarking sites but

http://www.samsung.com/my/consumer/mobile-devices/smartphone/android-os/SM-N910CZIEXTE lists the CPU as Octo-core and has the Exynos clock speeds.

FCC test is fine. Samsung has an attestment saying it's the N910C. They can't just change the model. Hardware gets finalized earlier, and then the software is built around it.
[Galaxy Note 4 General] Hendrickson:
You mention the Exynos for 64bit support later. But has it not already been confirmed the soc has 64bit disabled? It would not be able to run it? Source: anandtech.

Correct me if i'm wrong!
[Galaxy Note 4 General] arjun90:
The FCC states tests were conducted on a pre-production unit with the 910C being the Base Model. I really do hope the 910C is an international LTE Unlocked Variant similar to the 910F; otherwise, the 910F would have to do.

The 910C contains the latest Wolfson DAC.

---------- Post added at 06:20 PM ---------- Previous post was at 06:18 PM ----------

You're right; Samsung intended the latest Exynos model to be half-baked with no support for the 64-bit architecture. The same applies to Dell's Venue 8 Pro Windows tablet, which contains a 64-bit CPU, but OS is strictly 32-bit. Petition anyone?
[Galaxy Note 4 General] colster1000:
But I found this that says SM-N910U does support band 4. fccid.net/document.php?id=2381341#axzz3G8lJ0461 I'm so confused.
[Galaxy Note 4 General] Lodix:
It supports band 700.
[Galaxy Note 4 General] CLShortFuse:
It's not disabled. The problem is native 64bit instructions (drivers) weren't written for it. It makes sense considering that Samsung would have to write a 64bit layer for Android. That's a whole lot of work. Google is already writing one for Android L, so if ever in the future, Samsung creates the 64 bit drivers for any device running the same chip, somebody can cook up a new kernel with it.

Right now, it's running in some downgraded 32bit layer. The "if" Anandtech is talking about is Samsung doesn't ever have to write those 64bit drivers. I'm willing to take that chance instead of the 0% possibility Snapdragon brings.
[Galaxy Note 4 General] CLShortFuse:
Sorry. I mixed up the numbers. U/F/C/G support band 4 (1700mhz). Only the F/C support band 17 (700mhz). C runs Exynos while F runs Snapdragon.
[Galaxy Note 4 General] tmac31:
well you are right and plus you are still getting a 20%ish faster processor even if it stays as 32bit. even snapdragon 810 will be same chipset with probably better gpu and and higher clock speed and 64 bit enabled for sure.

only problem is does it realy support at&t lte? yes it connects for sure (some reviewers using it in youtube) but it is maybe struggling with battery cuz it doesnt fully support us lte standarts. other people reported good battery life on exynos but some reviewers in us said battery isnt good.

so you just need to be sure about it otherwise exynos seems realy better except custom rom support but as far as i can see touchwiz is running best of its time and realy good in general usage and as a note owner i assume no1 will want cm on it. root and xposed will be more than enough. atleast its my opinion.
[Galaxy Note 4 General] iznee:
Samsung Malaysia will release the SM-910C model this 17th Oct....initially I was going to wait for the 910F variant from europe or middle east..due to lte bands i needed most. Thanks to this thread I can now go home and do some shopping...thanks

[Galaxy Note 4 General] Lodix:
It says it supports band 700 but in B28, I guess it is not the same.
[Galaxy Note 4 General] CLShortFuse:
All of the benchmarks say the Exynos has better battery, but I will admit a lot of tests are inconsistent. As for support, I've had this dumb, locked Note 3 for too long and I can accept less custom ROMs. I honestly think people would be excited to make custom 64bit ROM and I'm hoping on it.

As for the AT&T bands, I'm going to trust the FCC data and that ridiculously detailed Korean wiki site.

In fact, I just bought one on eBay for $899. It ships from Malaysia so I'll get it in a few weeks. I'll keep you guys updated when I do.

[Galaxy Note 4 General] Hendrickson:
Don't all the Exynos ones have the Wolfson DAC?

Sure your right the 20nm CPU should be easier on the batter and the Wolfson DAC is slightly better I think. I'm looking at an SM-910U from Hong Kong.
[Galaxy Note 4 General] cmd512:
Custom ROMs are just repackaged stock ROMS nowadays with minor changes here and there, anything you really want to do to it from a modification standpoint can be done with Xposed. Kernel development is where it is at, and frankly, there isn't a single kernel in Snapdragon land that comes close to touching Perseus for Exynos.
[Galaxy Note 4 General] arjun90:
Seems like my eyes are on a 'C-Exynos'
[Galaxy Note 4 General] hello00:
so the tmobile variant will ship with exynos?
[Galaxy Note 4 General] CLShortFuse:
TMobile (US) version is SM-N910T which is Snapdragon. The benefit is you'll have Band 12, which is 700mhz LTE, which should use less power than TMobile's other frequencies
[Galaxy Note 4 General] Hendrickson:
I just brought the cheapest SM-910U here on ebay for 506 GBP / 800 USD which includes DHL/Fedex delivery. Much cheap than the other sellers selling for 950 usd.

Sure the snapdragon might have more Dev making custom roms etc. But it already has root and that's the main thing for me. And it's an unbranded non logo sim free model. Just have to freeze all the Samsung bloat when I get it and I think the Exynos will be much better on the battery.
[Galaxy Note 4 General] esziszi:
It seems the Snapdragon Note 4 can listen for "OK Google", with the screen off, like the Moto X (see http://xdaforums.com/note-4/general/psa-ok-google-screen-off-t2905510) . I read that the 805 has this functionality, maybe even the new 2014 Moto X implemented it without X8.

If this really works and does not eat the battery, and the Exynos does not have it, I change my preference to the Snapdragon version.
[Galaxy Note 4 General] cmd512:
It will eat battery regardless if the screen is off or not. The issue is not whether the screen is off or on, it's whether the device is awake or not. And, it will have to be awake to listen for the command.
[Galaxy Note 4 General] esziszi:
I was hoping for the 805 to have a circuit which can listen even when the main cores are asleep, like the Moto X8 system's "natural language processor". Maybe I misread it.
[Galaxy Note 4 General] istrikerx:
Actually theres a dedicated chip on the 805 similar to what the moto x had. Minimal battery usage.

About LTE

Hi, I just bought the same phone from the same person on eBay. Also, I live in Dayton Ohio, but the problem is that when I check my network status using "network signal info" from the play store it says I have LTE, but I don't get the 4G LTE logo on the phone and the speed does not exceed 6mb/s. Did you do something to get the AT&T LTE starting?

Thanks,
[Galaxy Note 4 General] corrupteddata:
With the firmware that comes with this model, you won't get "4G LTE" logo, just "4G", but they are referring to the same thing. As far as not getting the LTE speed you think you should get, I suggest visiting AT&T store or call them and ask them to perform what they call "provisioning" for your phone/SIM/account. Basically it's just a process of activating/initializing of your wireless service. Some people have to do this again when they use their old SIM with a new phone. Good luck.
[Galaxy Note 4 General] Q8guy:
I have two note 4, one with AT&T n910a, the other is unlocked n910c. You can see the two attached pictures. I checked the network at the same location with the same App, one has LTE which is the AT&T and the other is just 4G which is the international.

Also, I thought the same thing that the firmware does not show the logo "4G LTE" but I found on one website that the n910c does show the logo LTE and the pic is attached. Also , I already did the "provisioning" part two days ago, still no luck. I'll see what I can do. Thanks a lot.
[Galaxy Note 4 General] corrupteddata:
Not all N910C have the exact same firmware. Some firmware on N910C are customized by carriers that sell them and may have different LTE logo. I actually tried couple N910C firmware from different regions that are carrier branded available on sammobile site.
[Galaxy Note 4 General] sireniankyle:
Just got my N910C today. LTE seems to not be working. My box had a Malaysia sticker. So I wouldn't advise that firmware.
[Galaxy Note 4 General] shinasurada:
using the LTE discovery software, it shows LTE:N/A but when you go to the page where you reset connection, it shows that you are connected to LTE when you are in an area with LTE.
[Galaxy Note 4 General] sireniankyle:
So if it says that, am I actually on lte? Thinking of getting a new sim to help with the speed issue.
[Galaxy Note 4 General] shinasurada:
My phone seems pretty snappy so I'm guessing its probably on LTE. I have the Malaysian version too.

I don't get 4g alot because there are no towers in the area anyways. But I got a feeling that anything that isn't 4g absolutely destroys this phone's battery life. I don't recall the battery life on WiFi to be that great either.

I'm getting 3.5 hrs SOT. phone been off the charger for about 12 hours.

The countries that run primarily the same LTE bands as the USA are in the Americas so I wonder if they're more optimized for the particular bands we use. Maybe trying Trinidad and Tobago, Columbia or Dominican republic ROM would be better based on my research they run the 700MHz and 1700MHz LTE bands just as Att does.
[Galaxy Note 4 General] sireniankyle:
I'll try it out.
[Galaxy Note 4 General] sireniankyle:
tried Dominican Republic, and Trinidad and Tobago. Neither one helped, and the Dominican one gave me a stupid boot logo, and some weird app. With the Trinidad and Tobago one, though, while I didn't get LTE, I did get faster data speeds than with the Russian one.
[Galaxy Note 4 General] sireniankyle:
Went in to service mode and saw this. Almost convinced that i am on lte.
[Galaxy Note 4 General] shinasurada:
So the Trinidad and Tobago one had faster speeds than the Malaysian firmware?

Pulling up the service menu, I am connected to LTE band 17 as well.
[Galaxy Note 4 General] sireniankyle:
occasionally, but my keyboard shortcuts wouldn't activate on the T&T rom. So I had to revert.
[Galaxy Note 4 General] sireniankyle:
So i have been able to confirm that the n910c runs on at&t's lte bands 17&4 even though it won't say lte, it is.
[Galaxy Note 4 General] sireniankyle:
Forgot to mention that this means that an exynos device is 100% compatible with at&t, which is really cool.
[Galaxy Note 4 General] duvalbmarley:
Can someone confirm if either the c or u model works with tmobile lte in US
[Galaxy Note 4 General] sireniankyle:
The c is missing one of the bands. I think it's 25 or something. so it will work fine as long as you aren't in that area. I don't know about the u.
[Galaxy Note 4 General] vasuvius:
I just got the 910C. While the display shows 4G next to the service bars, LTE Discovery app cannot detect the LTE Band.

My N910C arrived in an hotel near to Time Square, NYC. The guy who traveled it to me (Argentina) tested it with a T-Mobile sim. He had H+ and LTE flawlessly and worked nice for two days. So I guess the N910C is the most, worldwide compatible Exynos variant of the Note 4.
[Galaxy Note 4 General] duvalbmarley:
Settings/about/status should show that u connected to lte 4G is lte on international version I have same model and lte works for me says 4G and lte discovery doesn't show lte on n910c

When the phone switches the HSPA+ or HSDPA, LTE Discovery clearly identifies that.

*#0011# in dialer should show what band doesn't matter what LTE discovery says maybe needs to be updated by developer for your device

In Lte discovery app it show LTE on the discover tab
[Galaxy Note 4 General] mw86:
I have a N900A (Note 3 AT&T Qualcomm Lte) and my N910C (Note 4 Exynos Lte modem) and I am using them both on AT&T service. The SIM worked right away swapping from one phone to the other with no problems from AT&T. The Note 3 I have on another line so I tested them side by side. Where N900A got HSPA+/HSDPA and showed 4G symbol the N910C got the same speeds using Speed Test and it showed H/H+ symbol instead. LTE Discovery identified both on the same tower and the mode they were in properly ie HSDPA/HSPA+. Where I get a LTE signal the N900A displays LTE Symbol next to the 4G symbol and the N910C connected 100% of the time to the LTE tower but shows the 4G symbol. LTE discovery correctly shows LTE is connected to confirm. The speed test as well confirms the LTE speeds are working correctly too and comparable or better than the Qualcomm LTE modem I used in the N900A. N910c has a max of Cat4Lte. Gladly here in up state New York US all the LTE frequencies I need are available on the N910C. As user above mentions the LTE frequency detection via LTE Discovery app may need an update by the developer or even may be unreadable with the Exynos Chipset.
[Galaxy Note 4 General] Cosmos81:
I am been following this thread and many others here om XDA, and I still don,t know what we will be the best choice for me, the N910F or the N910C..according to the battery-life.

The, Exynos with has 20nm, would be more power-efficient then the 28nm of the Snapdragon805 so I thought that would be the best choice, but in this thread and in a other one, I was reading that the, radio signal of the, Exynos is not a good as with the Snapdragon 805 which "results" in a worse battery-life according the Snapdragon 805 ?

As I live in the, Netherlands and mainly are going to use in Europe with 4G and wifi which version would be to best choice for me, according to the battery-life..

I had to update my SIM card in order to get 4G on my T-mobile service. It turned out my SIM card was so old, it never supported the LTE bands. After that my N910C now shows 4G next to the signal bars. At first I thought I got the wrong phone, or LTE signals were different in Hawaii, but in the end it turned out to be an outdated SIM card.
