Hi,
I am wondering whether the Galaxy S4 (I9500, specifically) can be used as a development board.
By this I mean something like the Raspberry Pi, BeagleBone, etc.
The I9500 already has powerfull CPU, 2G RAM and lots of ROM. What is missing (if at all) is:
# I/O pins. I am sure the exynos 5 has lots of I/Os, but the question is how many of them are accessible on the I9500 board? Looking at techinsights.com teardown article, the motherboard looks very dense and no I/Os seem to be accessible, but hopefully I a, wrong.
# Ability to run Android 4.0 (or any other version) with minimal resources. For example, is it possible to run Android in text-mode so that we leave the RAM and CPU power for the application we want to run/use?
# Availability of replacement parts individually. In such case, we would "buy" a blank motherboard with only the CPU, RAM, ROM and PMIC chips. All other chips (all of networking) are irrelevant. This should not be too expensive(or is it?). This poses another question about the ability to modify Android so that it still work without having the other chips on board.
BTW: Where is the GPS module? It is not mentioned in the teardown article.

Well,
the other thread is having discussion mainly about the Snapdragon 800 version, but since we Europeans can't have it, it is better to have the discussion about the Exynos models here.
Do you think Heterogeneous Multi-Processing Capability will be implemented in the Note 10.1 2014?

The wifi only model will be exynos based. I live in the US and only want the exynos version.
Why do you think that we (Europeans) won't get the Snapdragon 800 version?
In Europe
WiFi = Exynos
LTE = Snapdragon 800

Isn't that true everywhere?
Speaking of the Exynos version. How does the community support for those devices stack up against their snapdragon
siblings (thinking of s4 and so on)?

from what i have read and heard, the snapdragon siblings seem to have much more dev support than the exynos ones - that being said, with the new note 10.1, we might be able to expect some pretty damn good dev support so long as the rumors/claims about HMP being fixed are true. i think the biggest downfall of the previous octa chips is that they either use all 4 A15 chips or all 4 A7 chips, not a combination of them or anything else - the cache translation function is broken (i think thats what it is called... i may be wrong on the name).
but i think if they have fixed it, and if the new note actually offers HMP, then there should be some good dev support i would suspect - not everyone wants to pay for an extra contract for their device when they can just tether or hotspot to their phone, which they always have on them anyways.
On that *note* (pun intended) does anyone know if, on this new device, the 3g and lte models will have phone and sms functionality via headset of some sort? i can't imagine why would would purposely disable this feature, as the device has the proper radios etc for it. and if it is somehow disabled, does anyone know if that is something that can be brought over to the device with a new rom/kernel or other mod?
just my 3 cents, yea that's right, 3 cents....

Make a "note" to look into a program called Tablet Talk.
You can make any tablet into a sms/mms and phone... so worth the price.

Have definitely used and like tablet SMS on my new nexus but I just find it a hassle as the tablet always needs to be tethered anyways so I need my phone with me regardless. The idea behind having full talk and text on the tablet is so I don't absolutely need both devices with me all the time... I guess with a tablet that has 3g or late then you don't really need the phone with you anymore, and I can see an upside of this setup.... You can use just one phone number and have it accessible on two devices...just kind of seems ****ty to basically be forced into having two separate phone bills each month though if the option could have very easily been there to have the talk and text directly active and working on the tablet. I wonder if there is some sort of mod or hack that could be used to gain this functionality considering that on a 3g or late device the rradios are all there to support this.....

In all review that i saw, all tablet can phone and send sms/mms.
There are the apps for this.
So, i will buy the 4G version because i want the Snap800, and because it will have a lot of support then Exynos base...

what is exepcted price difference between Wifi only and 4g
what is the support that makes u willing to spend that difference ! is it from Samsung it self, or free developers !
will it be in just Applications ! or the Android system updates running !
this is going to be my first device,and i am already highly considering the 3G version as i dont have smartphone, and hope i can use the note (beside its main functions) as a smart phone + to connect to net when no wifi around or on the road , with headset .. but i will wait till after release to see reviews about that .
if the 3g not making call as a phone, i will get wifi, and for internet connection i will use usb flash modem (by OTG adaptor)

The price difference between the wifi only and 4g models can be $100-$200 for 16GB models, and sometimes you can't even find the higher capacity models in 4g or wifi. It can be a hassle trying to find the model you want. Data plans for cell based tablets can be ridiculously high for 4g models so have a carrier in mind if you want to go the 4g route. Keep in mind Im using 4g here as a generic term for cell based tablet (4g/3g/lte). Im sticking with getting a wifi based note 10.1 this time around because I hope to use it for content creation and media playback.
Kernel source
So, is this good news as far as dev support for the Exynos versions is concerned?

In john lewis web its only left the white wifi version. I hope that its because they are receiving next week the new one
'Note' that the tablet with not ship with HMP/GTS out-of-box.
They were recently finalized. They will ship with cluster migration/core migration logic initially. Later there will be some kernel/patch upgrade to have HMP enabled.

i was reading that in the octa-core you could only have 4 cores being used at a time; and that the lower ghz quad cores were to save power.
but if android's cpu governor will fluctuate the cpu speed up and down based on the workload, what's the diff?
doesn't that make the other 4 cores useless?
so in effect a 2.3Ghz quad-core vs a 2.4Ghz quad+1.7Ghz quad would have the same performance??
now if you can use more than 4 cores at a time that's a different story.
am i way off base here?

A bit. The architecture of each 4-core chip is very different; designed for different tasks. The weaker core is A7 while the more powerful core is A15. Your comparison is kind of like cylinder deactivation in a car's engine. In a V8, all eight cylinders are identical and they are shut off in pairs to save fuel and match performance to load. Think of Octa as a discreet 4 cylinder engine (A7) alongside a V8 engine (A15). Each, to your point, can be controlled so any or all of their cores can be active at a given time. The 4 cylinder's barely able to reach the low point of the V8's performance curve. Similarly, the V8 can't reach the 4 cylinders lower efficiency range. 85% of apps don't leave the A7 core so that's why it's more efficient than just shutting off some of the A15's cores; especially true at idle. It's actually a pretty neat approach to performance vs. efficiency.

FWIW the 2.4 vs 2.3 was a typo. Should be the same number there.
I understand where you're coming from, thanks for that. I just never heard it explained that a A7 at Clock X was different power usage wise than a A15 at Clock X.
If it is, so be it, that answers that. Would be interesting to see real world benchmarks behind it.

Hello, I am a bit confused. When the wifi version came out, users in this forum mentioned that there was no lag and the device was fast even running multiple apps. Now, I have read some postings saying that lag still exists. Could anybody please clarify? Is the LTE version faster and have longer battery usage?

I've read that the speed is negligible. Also I've read that the LTE version has a quick charge option & that it plays 4k video whereas the Wi Fi version doesn't & can't. I have the WI Fi version & I plan on keeping it mainly for update reasons (I don't like waiting for carrier approval). But I'm not certain about all this & would also like some clarity from those who may know a bit more about these differences.

I think you're right about updates. The LTE version from Verizon will never be updated unless Verizon pushes an update and you won't be able to flash newer ROMs because they lock their bootloaders. With wi-fi version at least you know it's hackable and you can flash updated ROMs all you want.
And charging speed isn't a big deal if you charge it overnight. Plus 4k is really rare anyways so no big deal there.

I have the wifi version and it is running smoothly. However, I was actually concern about the speed performance compare to the LTE version before I got the wifi. To be honest with you, I have no issue or complaints about the device. Everything running as it support to be. If you don't need the LTE like me, I tether it through my phone. Go with the wifi because as far as I have read it is only about charging speed and small differences. This is just my opinion and you will save money.

As the owner of a Verizon galaxy tab 10.1 who had to suffer through a 2 year contract I can attest to this. After purchasing it with honeycomb Verizon/samsung updated the tablet twice in the past 2.5 years. The ice cream sandwich update came about 5 months after ICS was out and at least a couple months after it was out on the wifi variant of the 10.1.
I just cancelled my service on that tablet in favor of tethering the wifi note pro as I am not going to pay this kind of money for a device with limited support. My 10.1 sits in a dock now at work in front of my keyboard serving as a glorified mp3 player and a testament to why I abhor carrier based devices.
Had it not been for the efforts of pershoot on the original galaxy tab 10.1 series it would have been even harder. Other than his incorporation of the Verizon variant into CM10 there were no custom ROMs for my tablet (there was probably one clean ROM but no ASAP type ROMs). I happily endured beta testing his builds for him and spent countless nights flashing his test builds.
I truly hope that some good developers pick up the LTE versions and build for them. Perhaps with the different cpu package they will, there was no such incentive on the original galaxy tab 10.1 series.
Oh and as for the question about battery life goes, I'm confident that the LTE variant will have less battery life all things being equal. It's just par for the course with LTE over wifi, as evidenced by any smartphone that enters a bad signal area compared to it being on wifi. Don't get me wrong, I loved the always on Internet access but this time around I just couldn't pull the trigger...
muzzy, I can see your disdain for verizon. I opted for LTE because of the snapdragon 800 chipset (has quick charge 2.0 just like the Note 3), this wasnt present on other lte tablets. Wifi, I usually like as well but the recharge time on my previous tablets had me looking for a newer solution.

I used the WiFi version for about 13 days, then returned it and plan on getting the LTE version.
I found the WiFi version to be mostly smooth (certainly smoother than the Note 10.1 2014 edition, that uses the same processor), however it does indeed have minor lag.
Here are the reasons why I want the LTE version ( because it uses the Qualcomm Snapdragon processor) over the WiFi
1. LTE version is faster and smoother without lag (unlike the WiFi version - every Exynos device I've used has had lag )
2. There's a wider range of compatible apps for the Snapdragon (some apps I use don't work that well with Exynos chipsets)
3. LTE version changes faster
Of course the LTE version is more expensive and may not get updates as quickly as the WiFi version.
I'm not planning on getting the Verizon version but rather the international unlocked version.
Verizon's track record on updates is simply brutal. Be prepared that you may see one update in a year and then they will most likely stop updating all together. Picked up a 7.7 last year. Got one update and that was it. Still stuck on ICS. All the custom rom's won't let the radio work even though they say they are for the i815 (Verizon model). I got 2. One for me and one for my wife and they are basically paperweights at this point. Never again. I'll tether my Wifi versions and not be tied to a contract for a device that rarely gets an update.
As for performance, My understanding was there is no significant performance difference between the Wifi and LTE. I know the Snapdragon will charge faster but since I let mine charge overnight, this is not a big deal for me.
Also kep in mind, you can root the WiFi version. My guess is the Verizon version may not be as simple to root and there probably won't be a ton of custom roms for it either though that is just a guess based on my previous expereince with Verizon tablets.

Hi,
I saw your post and thought I'd chime in here with a little info. I'm surprised that you returned the wifi model. The LTE version will definitely not get as many updates as the wifi model will. This is a most assuredly fact. especially if you are going to get the Verizon model. Verizon's track record is unbelievably terrible when it comes to releasing updates for their tablets. Just doing a general search on Verizon & tablets will fill your whole screen with pages and pages of complaints about this issue.
As far as the unlocked version that you mentioned I cannot really say. It will depend on the carrier that you choose to get coverage with. Just keep in mind that it is an LTE version that you are getting and there are only so many carriers. Among those carriers they themselves will have to test and approve updates as they are released by Samsung before they are rolled out to the devices themselves. So basically, when Samsung releases an update, non LTE models will get the update first. The LTE models will be limited to the software being tested an approved by the LTE provider, along with many features being locked out or removed from the software itself.
As for your post #1 that states:
LTE version is faster and smoother without lag (unlike the WiFi version - every Exynos device I've used has had lag )
This is most definitely untrue. It has been logistically proven without objection that the Exynos Octacore processor has more brutal knockdown power under a constant minimal and or maximal load than the Snapdragon processor. You might want to look further into your research on this because their is pages of data available on the Web that show this tested data readily available for your consideration.
You mentioned the LTE version does charge faster. I can say that is definitely a fact and you are correct. However the reason they intend for the faster charging is because of the cellular intended purpose. That being said, keep in mind the faster the charge is applied, the faster the battery consumption will be also. Not to mention that with the 9500maH battery the lifespan will inevitably be shorter as well. Over time you will notice that the charges will get faster and faster then will stabilize at a certain point. However the Non LTE versions will charge more slowly, giving the battery life a more in depth charge and a longer life span.
If the only reason your are wanting the LTE version is because of the "Lag", then I just want to let you know that you should definitely test the LTE version before making your purchase. If you place them side by side and test them under a minimal and maximal load, you'll see the Exynos will have less lag than the LTE version.
Please don't take offense to my opinion. Im only basing my opinion on what is factual from certified research information and my experience as a developer and consumer of both products.

Thanks for the info. I am also planning to get an international version. I don't live in the US. I am not affected by those carriers. I haven't heard of "There's a wider range of compatible apps for the Snapdragon". I thought except the phone app, whatever works under the wifi version should work under the LTE version. What apps are compatible only with the Snapdragon? Any examples?

The Exynos vs. S-800 debate is no different here than it is in the N3 and N10.1-14 forums. The N12 isn't new (it's a jumbo N10.1-14 which is already five months old) and there's nothing about it h/w wise that would make it behave any differently than the devices that came before it. Exynos and S-800 are so close in performance as to be undetectable. Certain games may perform better on Adreno than Mali but it's not so biased that people are complaining. Most of the lag being reported is in transitions and apps opening/closing. Those function never move off the A7 core in Exynos and probably use two of the four S-800 cores. Throwing more powerful h/w at the issue isn't going to change anything. The lag is caused by s/w and the s/w is materially the same on Exynos and Octa versions. I have a 3G Exynos N10.1-14 and have played with European LTE S-800 versions. I couldn't detect a performance difference and neither could my friends who own the S-800 version. And any performance difference you detect between the N10.1-14 and N12 is purely related to one being on 4.3 and the other on 4.4 with modifications to Samsung's UI and most likely drivers.

Link? Outside of a handful of games there's been nothing I've seen to support your statement. The bigger issues is apps that aren't optimized for the 2560x1600 display which affects both SoC's equally.

You might want to take a look at the Verizon Note Pro thread. On game based benchmarks, the LTE version came up14% faster on Epic Citadel, and 50 to 200% faster in Anomaly 2 than the wifi version. Snapdragon seems to be more efficient at handling the graphics load, which might also effect perception of lag.
I appreciate the replies to my post.
1) My opinion that they Snapdragon is always smoother than the Exynos and doesn't suffer lag like the Exynos is based on experience.
I've had several Exynos devices, all with lag, especially with the Keyboard and when scrolling on chrome browser and then intermittently in various parts of the UI ( Galaxy Note 2, Galaxy note 10.1, Galaxy Note 10.1 2014 edition). The Qualcomm devices I own do not exhibit the same annoying lag (galaxy S III, Galaxy Note 3, Tmobile version)
2. As far as compatible apps, I've had developers tell me that the reason why their app wasn't functioning well on my Note 2 was because Samsung doesn't release certain codes\drivers for their Exynos processor and that those apps would function better on Qualcomm processors. An example that comes readily to mind is call recorder by Skvalex. Also PDF max, when using the ink tool is very laggy on Exynos devices, but not on my Note 3
3) As far as comparing both the wifi and LTE versions, I actually have had hands on with both of them and in my experience the LTE version is smoother.
I really do not plan on buying the Verizon LTE because of their shenanigans as far as locked bootloader and abominable update stance. I'm still looking to get the international unlocked version, and not really for the LTE, but more for the superior Qualcomm processor.

The only Exynos devices pertinent to this discussion are the N3 and N10.1-14. The SGS4 used Exynos 5410 which, sadly for its owners, was pretty much an Octa beta test. I have a S-800 N3 and Exynos N10.1-14. I've played with Exynos N3's and S-800 N10.1-14's. In terms of everyday use (app opening closings, transitions, in-app performance) I haven't been able to detect a difference. Neither have friends who've played with both versions also. The are people in the N10.1-14 forum who went from Wi-Fi versions to LTE versions and reported they performed the same.
Perhaps in certain games or high-demand apps Adreno may outperform Mali but in all but rare occasions not enough for it to matter. Adreno 330, Mali T628, and PowerVR G6430 are the three most powerful GPU's on the market right now. They are probably in about 10% of deployed devices. Are people implying that a +/- 10% difference between the above GPU's is so important that the 90% of GPU's in use (which are a minimum of 25% behind the above mentioned) are suddenly useless and games and high-demand apps will perform poorly? It's actually the reverse. Developers know that the majority of device GPU's don't perform as well as newer releases and design for the middle.
It's also useless comparing Exynos and S-800 on all but the same device. My N3 is significantly more fluid than my N10.1-14 but it has nothing to do with Exynos and everything to do with the huge disparity in display area (amount of overall pixels being pushed).
Everyone's entitled to their opinion but some of what's being pointed out isn't supported by commentary on XDA. If the difference between Exynos and S-800 were as pronounced as being claimed the N3 and N10.1-14 forums would be lit up like Christmas trees discussing it. There are some "my SoC can beat up your SoC" discussion with folks claiming superiority for both Exynos and S-800 but for the most part the consensus it they are pretty similar performance wise.
One should also note that almost any lag can be eliminated if you tune your kernel governor to your specific usage pattern. You need root of course, which is an issue until there is a root exploit that won't trip Knox. There's no way I would root such an expensive device unless I can preserve the warranty.

fast charge or extra 32gb?
i am choosing between 2 models: p905 with fast charge option and p900 with 32gb more than previous one. i would like to hear the opinion of experienced users cuz never had any tablet before hence don't know what option is more significant in routine usage. in addition, i am definitely sure that never gonna use LTE function therefore in is not an advantage for me.
thus, the question is what to prefer: fast charge (is it really much faster?) or extra 32gb of memory (does it really matter for tablet?)
also the rumors tell that probably p905 with 64gb is coming soon (although, how soon and whether it will come at all...)
I have the p905 since it came out. Running smoothly. The only lag I experienced is when I played Sonic Dash. Don't know if it is a software issue with this app. Other games I tried (not that many yet) have no lag.
I bought the unlocked international 905 mainly for the faster charging and the ability to switch gsm carriers at will. 4K video, snapdragon 800 + adreno 330, no carrier bloatware, are icing on the cake imo. As far performance, this article claims a significant difference speed wise, in favor of the snap 800 adreno 330 combo. I haven't compared the two side by side. Of course ymmv.

Hi everyone, I'm just waiting for this new phone to be arrived home, wondering why isn't listed by asus site the quickcharging feature while Qualcomm ensures Snapdragon 430 supports quickcharge, 3.0 indeed.
Do you think Asus just disabled this feature as a marketing move, or as I think it is, their websites and webstores admins are really overwhelmed by the huge amount of variations offered for each device.. leading this into somehow missing important feature data on their webs.... (LTE bands specs are also quite hard to differ) ???
What do you think about it?
PD: Put some links as info sources
...
Apparently it does not have further circuitry to support the quickcharge feature, even though it's supported by cpu itself.
The difference isn't as big this year compared to years past, they are both similar in performance. That said, I'm leaning towards the Exynos just because of how much of a pain in the butt it was with rooting the Snapdragon model. Exynos was easy to root but the Snapdragon only got root because of a leak and it was unstable and laggy.
You are asking which one is better for a phone that isn't out for another 2.5 weeks?? And you can't say they are similar in performance based purely on a spec sheet! The spec sheet shows the exynos able to do 120fps at 4k, but it can't because the camera itself cannot perform at that speed so its still limited to 30 despite the exynos chip being capable of it.
Both SoCs and GPUs are too new to make any assumptions. Here's an article discussing S-835 on a Qualcomm reference device. It underperforms S-820/1 in certain benchmarks. http://www.anandtech.com/show/11201/qualcomm-snapdragon-835-performance-preview. Architecturally the new Mali GPU is superior to Adreno. What features Samsung implements and how they implement them is a wild card. When Samsung uses two SoCs in the same phone they typically tune them to be comparable as was the case in the S7-series even though Exynos did seem to have an edge. To an average user they wouldn't be able to tell the difference between an Exynos and S-835 equipped S8.
I've said this a couple of times in other threads. Exynos 8895 has new chip-based h/w security never before seen in an Exynos chip. Until its in people's hands it's dangerous to assume previous bootloader exploits will work the same way they did previously.
One difference that the Exynos seems to have but not sure how many people will notice. On the Samsung website and a couple other carrier sites state that the device the UK is getting only has Bluetooth 4 and not the newer Bluetooth 5 that the US and snapdragon market are getting. Wonder what other differences there are that aren't being advertised.
International versions getting a different version of BT doesn't make a lot of sense. They hyped being able to support two headphones connected at the same time during the unveiling which requires BT 5.0. I don't think they would have done that if the majority of the world wasn't receiving the feature. Carrier websites aren't particularly accurate.
You may have missed that part where I said it's shown on the Samsung website too. In the U.K it's showing as BT 4.2 LE. It's possible that the new BT 5.0 isn't compatible with the Exynos chip for some reason or just not optomised to work well together yet. Also that launch was predominantly geared towards the US market as almost no information regarding the international versions was spoken about on stage.

I am pretty certain thats a mistake, there are mistakes over the web on the phone specifications. The global S8 specifications say Bluetooth 5.0
"Exynos 8895 has new chip-based h/w security never before seen in an Exynos chip."
What EXACTLY does that mean. Because whenever I read or hear term, "security" it raises eyebrows. This is umbrella terminology for those in a state of fear requiring reassurance, but to those who don't carry around such weighted down impedances it would be interesting to know exactly what is implied here.
Yeah the specs are all over the place at the moment. I'm putting a tiny bit more weight behind what is on the official Samsung UK website that my pre-order leads me to which is saying it has BT 4.2. But one UK carrier (EE) is claiming it has Snapdragon 835, and another carrier (Three) is claiming BT 4.0 so nobody seems to be on the same page in the UK. Anyway I'll know for certain next week as my pre-order is arriving 20 April.
"The Samsung Galaxy S8 is the first of its kind in the United States, and it is the first of its kind in the world Up to 24 bands worldwide. Samsung offers with the new S-Class for the first time in a smartphone Bluetooth 5.0, which is integrated both in the version with Snapdragon 835, as well as with Exynos 8895-SOC."

The Exynos is roughly 10% faster in single core and multi-core than the snapdragon (Geekbench, above video). You would hardly see a difference in most day to day use as both are pretty fast.
But the Exynos 'Mid Power Saver' which downclocks the CPU gives you the same performance as the the 835, so the exynos would obviously be better as you can have the same performance with more battery life (assuming it does save power)
My Exynos Edge 7 plus did not suffer any slow down over time while Snapdragon version crawled to a stop
I've had my Snapdragon S7 Edge since they were first released. My phone is still working great. It has nowhere crawled to a stop. Maybe for some reason some of the Snapdragon S7's slowed down but mine certainly hasn't. As a matter of fact the only reason I'm getting a S8 is because my S7 Edge has an over sensitive screen. If that wasn't an issue I would keep it for at least another year. There is no way I would do that if it slowed to a crawl.
Exynos Should always be in theory. It's in house processor and Samsung can do what they want and how they want with the software. So it should always be better optimized as you know exactly every aspect of the hardware.
