If production starts end of this year, it will never make it by march. Most likely it will have the Exynos 5250 (Exynos 5 Dual) dual core 32nm 2.0Ghz. And you gotta understand Samsung's Galaxy S team is like the A-Team, and everything is secondary. So Most likely the 5450 won't be on the Galaxy Note 3 either. It will just have an overclocked 5250.
So if you're saying you're going to wait for the Galaxy Note 3, by then Galaxy Note 4 will be around the corner when the Galaxy Note 3 is available. Don't really understand the logic. There will be something always better in a few months. What's the point of waiting for a device based on speculation?

I understand, But, i dont think Samsung is gonna downgrade on their Flagship smartphones...we just need to wait and see....

i dont get the logic of some people, why do you always have to get the latest and greatest? is there's a hole in your life that this gadget will fulfill? the Note 2 is crazy smooth and fast, why do you really need a 1080P 5" screen that i bet you wont notice the difference and hardware that doesn't has software to take advantage of?

if it wont give better battery life, then i dont care to be honest. Performance note 2 has more than enough. With more software optimization, note 2 would be even faster than now.

OOOH Now we are talking....

for sure :silly:

those are some awesome specs. glad my note 2 will at least last 2 to 3 more years. just like my q6600 + 9600GT which is perfect even after 4 years lol

Finally samsung will have a phone as fast as galaxy nexus.

There needs to be significant improvement (or something wrong with my current phone) in order for me to "upgrade".
That's why I said MEH when I saw the SGS3, but decided to upgrade when I saw the SGN2. I have an Android phone, not an Apple... I don't need to buy the latest iteration of my phone to feel special.

You don't need the latest apple product to feel special. I still have my iphone 4 running just fine though i think this is a bit offtopic.

Forget about updating. Why am I sticking with Samsung for this long? It's AMOLED! Note 2 is one of those adorable babies, and not many I had, yet I owned plenty. Other must mentions are (were),SE P910i, Xperia X1, BB Bold 9000, iPhone 4S, Samsung Wave S8500 and GS II. And now, this one.

Next time in upgrading is for the note 3

I'll most likely upgrade to the note 3 next year when it hits if my finances allow it.
That is unless it has less battery life than my current note 2.

Comparing the 10.1 to the new 8.0

Hi guys
Need a little help if u can...
On a local pricerunner like site I can find different specs on different versions of the Note 10.1 and the Note 8.0 in terms of processor.
For the 10.1 I can find two set of specs: One with a 1.4 GHz quad-core Exynos processor and one with a 1.4 GHz Cortex-A9 processor. Both called Samsung Galaxy Note 10.1 (one is grey the other is white).
For the 8.0 I can only find a 1.6 GHz Cortex-A9 processor.
I guess what I'm asking is what's the difference in performance? Cuz' theres only about 20 USD between the 8.0 and the Exynos 10.1...
If anyone has some input it would be much appreciated

In real world usage you won't see a difference. The only time it may make a difference is when using benchmark tests. I would choose the tablet on which size is better suited to you rather than the cpu. ln the electronics game, they will always try to increase the number, whether it be ram, cpu clock speed, number of cores, resolution, or mega pixels. The consumer is led to believe that if it has a higher number it must be better. Usually it's just an incremental increase which doesn't really make a difference when using the device.
The 8.0, does have a the same screen resolution but on a smaller physical screen, so it'll look a little bit sharper. Personally I like the larger size, but some people prefer the sharper image. Especially when using the s-pen, I think the extra screen real estate helps. It is also beneficial when using multiview windows.
How much is the Note 10.1 going for nowadays? Last time I checked Costco was selling it for $429 with a free zipper case.

So I shouldn't worry about getting an Exynos or Cortex-A9 processor?

Well here in Denmark the best price for the 10.1 is the grey Exynos edition selling at around $550 :-/ No case included. The Cortex-A9 edition is about $50 more.

I bought my Note 10.1 (16gig, wifi) on sale, for 385 Euros ($535) here in Norway two weeks ago, may 10'th, but they are back at 515 Euros ($715) again

Like he said he can't tell u directly which is for you. You can't come online and ask for which processor to get because like he said during use probably 95% of users can't and won't detect a diff.
Get a tablet based on size and functionality that's suited best for you.

I got my Note 10.1 (16gb, wifi) for about $380 (taxes included) because of some SD sale a couple months ago. I don't think it's ever been that low since . Honestly though, I think you should choose the tablet based on the size. Personally, the only reason I'd upgrade my tablet now is if I could purchase something similar to the Note, but bigger (13"-15"). Otherwise, I love my Note for everything I'm trying to do with it.

I have both, grey note 10.1 since it was released, note 8 about 1 month.
Here are some opinions and other considerations
Performance - for me both are fine once bloat is removed - 8 has the edge.
I can overclock note8 stably to 1.8, but don't bother since it works fine at the default
Battery life - (my usage pattern is a couple of hours per day) - note10.1 wins - my charge was 1 per week,
Note8 about 3-4 days, not sure yet whether software or display.
Weight - note 8 is my preferred carry to work
Screen view comfort - note 10.1 wins with size of display
Spen writing, if you are holding the tablet while writing, 8 would win. If your normal placement was on a desk the 10.1 would win.
Charging - note8 much quicker (3.5 vs 6 hrs).
Accessories: consideration for cost if you already have accessories like otg-usb or mhl-hdmi adapters, the 10.1 has samsung 30 pin adapter, so previous 30-pin hdmi, usb etc work fine. The 8 has 11-pin micro-usb, which works with some old otg-usb adapters (eg for S2) but needs a newer vintage HDMI adapter. (The 30-pin adapter looks way more robust than the micro-usb).

Just to clarify things all note 10.1 and note 8 use same processor exynos 4 quad (but with different clock speed 1.4vs 1.6) the cortex a9 is the type of the processor architecture not a processor brand so there is no exynos note 10.1 and cortex a9 note 10.1 both white and gray use cortex a9 exynos 4 quad , good luck with your choice

That's the cheapest I've ever seen it. For some reason the Note 10.1 doesn't go on sale as often as the Tab in either size.
If you're in the U.S. you might want to wait till "Black Friday". I got mine just last year at Best Buy during Black Friday and it was $50 off( and no I did not have to wait in line). A lot of online retailers also had it in their sale.

Exactly, Galaxy Note 8.0 and 10.1 share almost the same hardware. The Exynos is just clocked higher like the Note II. You only need a Kernel to reach the same clock (if you need it, I don't).
Furthermore the Galaxy Note is quite expensive at the moment. Last week when I checked prices at amazon Germany the price for the 3G Versions the Note 10.1 was 10 Euros below the 8.0! :silly: (440 vs 450 Euros)
I give you a tip:
If you are writing a lot (like me as a student) buy the Note 10.1.
If you can wait for a special offer (maybe 2 weeks, maybe 3 months, you never know) and like to have a more handy tablet, then buy the Note 8.0.

I previously owned Note 8.0 and I really liked it but it had it flaws... which eventually made me to change to Note 10.1. Things that bothered me on Note 8.0:
- Heat. While gaming and even in browsing the device sometimes tended to heat about just too much. Still usable but definetely bit annoying.
- Battery life. I use tablet thru whole day for work. Note 8.0 run out of juice just bit too early whereas Note 10.1 still can join me for games and movies after work with single charge.
- Screen issues. Excessive backlight bleeding. I checked several and all suffered from this. But I have read some people reporting not having any. So I guess you just need some luck. Also I see stucked pixels in some.
- Camera. Much worse than Note 10.1. I just want to take at least fairly ok pics and Note 8.0 just can't deliver.
Anyway, some of these maybe fixable (heat?) with firmware update. But my Note 10.1 just works better for my needs and can push easilly thru the day.

My Note 10.1 charges much faster, from 10% battery mine consistently charges in 4hrs 25min. (See attachment from 5%)
I also like the 30-pin connector because over the last 6 months I have seen literally 100's of tablets of various brands for sale on ebay with damage micro USB charging ports.
As far as price goes, deals can always be found on ebay from reportable sellers. I got my new Note 10.1 Dec. 20th 2012 for $385.00 delivered.
Currently on ebay ........
Dark gray 16gb - Buy me now $399.00 delivered

About the same charging time for me. About 1h more than 8.0 in my experience.

Undecided between Galaxy S4 and Note 3

Hello everyone, first of all, I am galaxy S4 user, I have both octa core and snapdragon. I am pretty sad about the poor battery life of Exynos S4(I play a lot of game) and the lack of custom developpement in the i9500 section.
I am pretty happy with the i9505 even if it "lacks" performance(I know, even if it is already a beast with snapdragon 600) compared to the octa core and the future "Snapdragon 800" which will be rumoured to be integrated in the Galaxy Note 3.
I don't care if this device has 1 inch larger screen or something else. All I need in a phone is the absolute performance and the perfect fluidity when using. The only problem is that I am not somebody patient. I have to wait 4 or 5 month until the Note 3 being released. So does this device really provide enough performance that I should wait for it?
(if it uses the octa core, I am sure to not buy it). Thank you for your advice.

Even when the note 3 is out, there will be another beast coming on the way. It's a continous run given the rapped technology progress! If you are always seeking the ultimate best, then you'll have to change your device every +/- 6 months! Maybe even more frequent in the near future!

Be happy with what you have.
There wont be much noticeable performance again.

Yes, but this time, we will got the fresh new Snapdragon 800, I cannot imagin how gaming will be cool on the big screen fast device. It can be good to take note too.

[Discussion] New Samsung Galaxy S6?

It’s 2015 and hence time for a new Galaxy S Series flagship from Samsung. In earlier reports Samsung has claimed that it will completely change what we have witnessed in the Galaxy S line so far, starting from scratch there will be an all new Galaxy S6. As it goes for a Samsung flagship, the specifications that the Galaxy S6 will hold will be nothing short of impressing but the dream to get 4 Gigs of Ram isn’t just here yet. The Galaxy S6 is already cooking up and not a long time back arrived in India for R&D purposes, hence our sources have managed to secure some information on the specifications the flagship will boast.
These specifications are intended for the Asian units, that have since beginning relied on the Exynos SoC’s. The variants intended for the North American and European markets will be using a Snapdragon SoC’s instead (Snapdragon 810 Likely), while keeping the Ram, Display, Battery and undisclosed specs identical.
Also beside the already anticipated spec-sheet, the Galaxy S6 will be using a Metal Exterior (similar to Galaxy A Series) with a new much slimmer design. Stay tuned for more updates and feel free to share your thoughts about the next Galaxy S flagship.
SPECS:
5.2 Inch Quad HD Display (Amoled)
3GB Ram & 64GB Internal Storage (Micro SD Missing in test Units)
Non-removable Battery (2800mAh)
Exynos 7420 Octa-Core Processor (Dual Quad-Core)
Finger Print Scanner
Heart Rate Monitor
Android 5.0.1 (running units)
20MP Rear & 5MP Front Camera Unit

The specs are pretty much accurate (not very hard to guess as they've been predicatble for years.) but that picture/render is wishful thinking.
Aside from the fact that test units come in fake cases, as they've always done, these leaked images are always fake, every year in a row.

It's looking like this will fix all the wrongs of the S5:
Class leading CPU/GPU on 14nm
Premium metal build
Touch based fingerprint sensor
20 mp 2nd gen Samsung ISOCELL sensor with phase detect autofocus and OIS
The next evolution of AMOLED
I'll be all over this as long as Touchwiz is not a complete disaster

Samsung Galaxy S6 Specifications
Samsung Galaxy S6 may come up with a Exynos 7420 processor as Samsung may drop Snapdragon 810 due to heating issues.It may be announced at MWC 2015.

Here is the leaked design of Samsung S6
http://androidjail.com/samsung-galaxy-s6-specification-body-leaked/85

The quad hd is a mess . in normal use , practically you don't need it

This post is misleading about rumors

Do you think that will be hard to have bug free custom roms with the exynos cpu?

I'm looking forward to March 1st... there should be some pretty cool info at the unveiling.

I'm all in for another Galaxy, but all these leaks without a sdcard slot make me a bit nervous.

Don't give your hopes up guys and really don't put too much stock into all these leaks. For the last few years all the supposed reliable leaks have been wrong and Samsung basically reintroduced the same damn phone. Well their not getting me this year no more hurt feelings, so until I see add to cart next to a s6 picture the new s6 is the s5 with upgraded hardware
Moto X 2014

Prediction: S6 will be an uglified but high spec S5, much like the S5 was an uglified S4 with better internals. Add the new crown jewel Exynos SoC, revamped KNOX and Samsung's traditional hamfisted massacre of Android, and I further predict less dev support than ever.

hi
i phone 5 and s6 this kind of better, I want to buy either and are wondering

2800 mah battery? omg! why samsung not trying to improve battery performance? 2800 mah will be enough?

Thread Closed.
As we have multiple threads about the specifications of the S6, one official one has been opened here: http://forum.xda-developers.com/galaxy-s6/general/specs-samsung-galaxy-s6-specifications-t3034238

Please Help. Only a Single person Replied in a Day!

Hi All,
Thanks for coming to the post. I know this is not a review website, but I could not find the solution anywhere else. I need your help in choosing my next phone. I am deciding between Samsung Galaxy A9 Pro ($350) and Xiaomi RedMi Note 3 ($200). I know the price difference between them is somewhat unjustifiable, but I am choosing between mid-rangers from Xiaomi and Samsung. Now I have a few points to make so that I can have a proper explanation.
Before starting, just FYI, I am using Samsung Galaxy Note 3 and Xiaomi MI4. My father has a RedMi Note 3 and my sister has a RedMi Note 4. Beside these, I have used many phones from Samsung and other manufacturers as well. So I fairly know how good phones both manufacturers produce.
1) Galaxy A9 Pro in India comes with S652 chipset flanking 4GB RAM and 32 gigs of storage. RedMi Note 3, on the other hand, is available with S650 chipset having 3GB RAM and 32 GB storage. While the specs are in favour of Galaxy A9 Pro, why RedMi Note 3 has upper hand in most benchmarks? If it is because of TouchWiz, does it lags horribly?
2) A (very) few people, including GSMArena, mentioned a kind of screen flicker in Galaxy A9 while in low brightness. Any explanations on that? Does Galaxy A9 Pro suffers from same issues?
3) In a dual sim phone, if my first SIM is 4G/VoLTE based (Reliance JIO), what would be the supported network on 2nd (GSM, 3G or 4G) ? I have heard that 2nd SIM stays in 2G. Is that true for both the phones? I have also heard that RedMi Note 3 supports 3G in secondary slot.
4) Galaxy A9 Pro misses out the Gyro Sensor. Apart from VR, what else I'll be missing out if I opt for Galaxy A9 Pro? Also, what is the cost range for a decent VR box (I am poor)?
5) Do you knoy any video or website link where I can see a thorough overview of Galaxy A9 Pro UI? There are certain features I like in the ROM itself, and I do not want to root the new galaxy on day one. Fortunately all of them are available in MIUI, but I need to see someone's Galaxy A9 Pro. (App lock, Headsup notification disable, inbuilt data saver etc)
6) How good is the battery backup for Galaxy A9 Pro?
7) Samsung recently discontinued Galaxy A9 Pro in India due to which, the price has fallen from almost $500 to $350. What could be the reason behind it? Is there any production fault?
8) Samsung Galaxy A9 Pro is available for $350, Xiaomi RedMi Note 3 is available for $200. Considering all of my requirements and situation, should I spend $150 more for Galaxy A9 Pro?
Is there a nifty alternative for Second Space or Dual Apps from MIUI? Parallel space is a fairly poor adware, and even if I buy it for $3, it is a resource hog. Any recomendations?
Thanks for your time and input.
Have a great time ahead.
P.s. Mi Max Prime is too big for me.

I think the more important is : Do you want paid 150$ for toucwiz and what design you prefer ...
And touchwiz is nice now. No samsung doesn't have second space like MIUI and idk a good alternative

1. I have heard that this phone comes in 4G+2G connectivity. Redmi Note 3/4 on the other hand comes with 4G+3G connectivity. Is this an important thing to consider, because if I am using internet from first SIM, the second SIM will only be used for calls. So should I be worried about this thing?
2. Can I select 3G/2G on first SIM and 4G on second SIM without changing the cards?
