[Q] [DISCUSSION]Note 4, 64-bit, and Android L - Galaxy Note 4 Q&A, Help & Troubleshooting

Hey guys.
I was searching on internet about Note 4 and I found an article about note 4 and Exynos 64-bit processor. Immediately I jumped xda to talk with you about this. (Link to article)
I've just found a topic here which is nearly same, but I have some other questions to discuss. (Link to the other topic)
So as you guys know there is two versions of Note 4 which is Snapdragon and Exynos. As far as I know Exynos processor version is accually 64-bit. (I'm not sure if it's true or not.) We all know that Snapdragon version is way developer friendly so it will have more custom staff. In the other hand we might have a 64-bit processor which is marketted as a 32-bit processor by Samsung. (Again as far as I understand from the article above.)
So here is my concern. I don't know if devs wil work on snapdragon or Exynos but do you guys think that Note 4 Exynos can be used as 64-bit by the customizations done by devs since Android L supports 64-bit?

The display-quality must be so awesome... the colors are so nice . cant wait...
ARMv7 is the instruction set architecture that it is running, not the processor. That's like saying that a new windows machine is running on x86. It's a given. They're all ARM. Well, okay, the fact that it's ARMv7 tells us a bit more than just saying that a windows machine is x86, but still. Maybe a better example would be saying that a new windows machine has a sandy bridge processor. That could be anything from an i3 up to an i7-extreme.
Anyway, it's already been confirmed that it is using a tegra 2.

Confused with Quad core and Octa core

Please help me to choose ....should i buy a 2.5GHz processor quad-core Qualcomm 8974 Pro or an exynos octacore (Quad 1.9GHz + Quad 1.3GHz) variant of s5?

You should buy the model that best fits your needs. Each one has some advantages over the other. The primary determinant for most people would be which model is best supported by their carrier.
Speaking only for myself, I would never buy the Exynos (octacore 900H) because there are many more Qualcomm models (quadcore e.g. 900F) and as such they are much better supported by custom ROMs and Developers in general.
There have been countless threads about this, full of useful informarion. It's a good habit to search before posting. Have a look and you'll learn a lot about the phones that you are contemplating.

I have to agree with you, in the most pain full way. I had no choice and I bought Exynos. For 4 months I have been waiting for a custom rom. I continue waiting. There are only two or so, samsung debloted roms.
Qualcomm quad core better... More Dev support.

Proper 6039Y (4.7") vs 6045Y (5.5") signalling

Hello there
I recently acquired our beloved Idol 3, the 4.7" variant (aka 6039Y), and I couldn't help but noticing a rather disturbing fact :
=> Any information about the 6039Y model is diluted in general threads or buried inside the 6045Y threads ...
Would it be possible for everybody posting information/patches/docs/etc specific to the 6039Y model to post stuff in specific threads with a [6039Y] tag in the title somewhere ?
I believe this would make finding relevant information way easier for everyone
I still dream of unified methods/patches for both models, considering both devices shouldn't be that different, but that is up to the volunteers providing the software to decide.
What do you guys/gals think ?

The problem you are gonna have is that you 6039 users are kinda gonna have to run with the ball because your root method AND version of TWRP is totally different then the ones for the 6045 so you can't even follow our guides (for example your version doesn't offer the option to backup "System image" which included partition info). Since no one has done it I don't think anyone would have an issue if you started "how to root on the 6039" and "how to install twrp on the 6039"...notice I'm not identifying a letter because I don't know if the 4.7 model only comes as a 6039Y....the 6045 has 6045i (usa/canada), 6045Y(europe), and 6045K (Various other places). There is also a rumored 6045B.
Dose the 4'7" even have same specs as 5'5" normally the specs ain't the same in smaller version CPU and ram etc , ie s4 quad core 2GB and s4 mini dual core 1.5gb and have totally different root guides and methods , I believe both variants will get good support evench its a cracking device and support is slowly building

Different hardware. Different root method. Different version of TWRP. Different method of backing up system image. Basically the only thing that is the same is the fact they call both of them an "Idol 3".
Thought as much

Considering both phones are Qualcomm-based, I would assume they aren't THAT different after all ? (I AM new to Android development, so there must be something I'm missing for sure )
I mean, Android is based and Linux, and our chip is just yet another ARMv7 chip which the linux kernel supports pretty well, so what makes an ARMv7 chip different from any other ARMv7 chip ?
Do they optimize the kernel so far that they strip anything useless for each phone out of it, effectively rendering each kernel useless on any other phone ?
One last question : wouldn't building a generic ARMv7 kernel from this page be a good starting point ? (msm projet is for Qualcomm hardware) : https://source.android.com/source/building-kernels.html#figuring-out-which-kernel-to-build
Note that I might be daydreaming here and I don't fully realise what amount of works this implies.

You need to spend some time reading the existing threads such as the root thread etc where alot of this has been covered. http://forum.xda-developers.com/idol-3/help/root-ability-phone-t3116179
4.7" and 5.5" models have different hardware
The whole forum about Idol 3 is a big mess to me because most people do not realize that the Idol 3 comes in many different hardware configurations.
Indeed we should start stating comments in for at least 5.5 and 4.7 models. (GPU/3g/4g is different and what else) or for both if it applies.
Although this forum already implies it's about a 5.5 model according to the home page, there are many different hardware models discussed! We need active moderators when roms start roling to distinguish ourselfs from lemmings!
Maybe ask a mod to make a 4.7 model sub-forum.

feature of our note 3

will our note 3 snapdragon support vulkan API our not
so no one know -_-
The Vulkan Wiki is where to look
A 3 second google .
Android support due for it in Android 7 Nougat .
Thanks for answering
But i mean note 3 will not get android n officially of course but if it get it as cm will it run vulkan??
Only Sd820 support. Sd800 is too old. Let's see if miracle happen.

Samsung Tab A 64bit or still 32?

just a quick question before purchase sm-p550
are these tablets 32bit or 64, how does one actually tell?

It's 64 bit, there are apps that tell you device info, a d thats what it reports it is, also i tested the dolphin emulator on this tab and it installed and it is a 64bit only app.
well it turns out the SM-P550 touchwiz is arm 7 32bit and takes the v86.0 sdk23 arm version of xposed for 6.01 marshmallow

What? My English is not good enough. I understand that tab A is 64 bits but Samsung launcher is 32. Is that it?
The processor is x64, bus bandwidth though is 32 bit.
A 64 processor with a 32 bus? It's like a big parking with a little in/out! LOL

it is NOT 64bit, it does not have 64bit run time libararies nor libs, I know I build custom ROM for it...
unless you guys talking about upcoming new Tab A, that's different story
T580 has 64bit Exynos processor.
I have sm-t707 at&t (32bit exynos) and sm-t707v (32bit snapdragon) and my son's sm-t580 (64bit exynos) the power and responsivity of snapdragon is much higher but graphically is poor exynos 5420 is much better, sm-t580 (exynos 64bit) has exatly the same power of sm-t707, but energy compsuntion is HALF (!)
Can I update my galaxy tab A so that its bandwidth is 64 bit

What about the (SM-T380) Galaxy Tab A 8.0 (2017)? because I upgraded my guess is that the newer tab A 8.0 can run 64bit apps but has a 32bit system?
To me 64bit sux hind tit. I have been messing with 64bit tv boxes, the best and most reliable run 32bit firmware.
At least in my testing up to Nougat 7.1 , there is no real world benefit with 64bit firmware. In fact it bloats your system big time. Peeps in the know, know what i am talking about.
I can't believe its almost 2020 and peeps think more bits is better. Until they make risc cpus mainstream, nobody will really know any better. This type of talk has been a gimmick for adding sales since 1988. More bits don't do squat without a true os to make it work, and apps built around it. If you want speed, get an octacore or multi octacore system, dont waste your money on bits that go ignored with most apps.

According to Google's plans, after August 1, any apps and app updates that include native code are required to provide 64-bit versions in addition to 32-bit versions when publishing to Google Play. For the 32-bit diehards, Google has an additional shot of bad news: Google Play will only accept 32-bit only updates to existing games that use Unity 5.6 or older until August 2021.
It sure looks like Google is inching toward the line of 64 bit only.
I know the processor is able to handle 64 bit and that Android 7 is using a 32-bit environment. I have the update to 8.1 downloaded but what I would like to know is did Samsung add the 64 bit environment to the 8.1 update. I would assume no..as I don't expect for a happy ending. I normally could care less. However, Elder Scrolls Blades is the first app i have come across that will not install and say in the installer itself it is not compatible. After looking in the logcat i saw that it failed when attempting to access 64 bit instruction set..or libraries...whatever it is had 64 all over it. So can anyone give me the absolute answer that Android 8 on this tab is still 32 bit or does it have the 64 bit native?
the other issue with Samsung is the lack of kernel and device trees for there roms means we cannot even easily make a 64bit custom rom like lineageOS with out struggling to figure out the proper way to port with the configs and what not....
so then we are screwed if we arent a dev. Its already hard enough to even find the SM-P580 in xda forums. Let alone have someone go back in time to the tab forgotten. Unless I missed a release..this one is the last over 7 inch tab with an s-pen. Well after typing that i looked at samsungs website and realized I missed it because they kept the S4 brand and slapped it on a tab. I'd try the kitchen myself if there were any ROMs out there that i could at least get permission to mess with.
