Thank you, but not now. I need to figure out some things. I'll let you know when it's ready.

@JohnTrabusca
I've left you a PM

@alexander_32, I'd be interested in building tate and jem if you provide a roomservice.xml file for cm-14.1. This is my setup:
ASUS ROG GL752VW-DH71
I replaced the 1TB drive with an ADATA SX900 512GB SSD. I set my virtual machine as such:
- Ubuntu 16.04.2 LTS
- 12GB of 16GB system RAM
- 6 out of 8 CPU threads
- 160GB of storage
I'm interested because I had a jem that I gave to a family member and I'd be looking to upgrade it to Nougat eventually.

[Q] Kernels, Phone Setup, RAM, Scripts

Hey guys!
I noticed in the specifications of this phone, it claims to have 0.50gb of RAM (512mb) However all your kernels are around 370 of under?
Is this mistake in the specifications or are you lowering Ram for some strange reason unknown to me?
I'm using liquid smooth build#2 at the moment, but i'm only getting around 99mb free Ram.. I don't know why but it seems the Phone has less Ram then i initially thought.. However, i don't have any scripts going at the moment, i don't need battery, so any " and it's good on battery " will be respectively ignored.
I have looked around but not really found a decent enough set up for this phone yet.. Can someone please recommend me a kernel for 4.2.2 which is fast, and responsive, but also one with good Ram?
And can someone recommend some scripts worth using with this Phone? Again, don't go on about battery or SD life or phone life, idc about it, it's a spare phone..
Thanks in advance guys, could you provide me with links as well if it's not too much trouble? I prefer being directed straight to the point so i don't end up using the wrong Kernel/script..
Edit1: I'm not changing Rom. At all. unless you get an updated Carbon or 4.3.

Seems noone is willing to reply, but this probably because some searching and logical thinking would answer your questions. So since you are not willing to do it yourself others don´t mind replying to you.
So well I don´t use any scripts but regarding RAM size think about it. If you buy a PC with lets say 2GB installed RAM. Will you get also 2GB free ram by running an Operating System on it?

If you were to purchase 2gb of ram likelyhood is you will recieve 1.59+- usable Ram, free Ram would be totally different, however the way it was presented, and the way i portrayed it was thet the Ramdisk of the kernel was at 370+-, rather then 512.. I'm using a Desire C, which is running CM10 with 300mb free ram, with a 512mb ram disk, whereas with hurtskys kernel 3.0.x i get 99mb free? on 4.2.2 on my golfu i got 270mb free ram, and that was a Rom of 250mb+ and it's only at 767mhz.. yet seems smoother then the SGW? :s On paper it should be the other way around..
dun think u should worry about free ram.
android is based on linux, linux memory concept is different from other OS.
it something like " free memory is waste memory".
memory is always filled and hold so tat it wont waste time to reload.
if need more memory, system will free memory for other usage.
maybe this will help explain better, http://www.linuxatemyram.com/

You should first read what a ramdisk is. https://wiki.archlinux.org/index.php/Ramdisk
The 270+MB in hurtskys or my kernel is the real RAM aviable. The rest is reserved for the ROM, camera, drivers and processes to work correctly.

[Q] No 64bit - so what?

Hey,
So I keep hearing a lot of complaints that the Note 4 processor does not support 64bit (nor does Android 4.4), however, why does that really matter. The Note 4 has 3GB of RAM, not 4GB of RAM, therefore 64bit is not required.
Regards
Well, it's more that the chipset does support 64bit. 64bit is coming to Android, I believe the upcoming version.
The big deal is you can process more information at once on 64bit versus 32bit at one time; actually double. It really doesn't have do with ram. Although ram can be important for storing information to be processed or has been processed. I don't know if Android has the ram issue like Windows does with 32bit versus 64bit; I would look to Linux for an indicator.
This will be more important when we're getting true eight core mobile devices. Real speed doesn't come clock speeds, it's more about the numbers and buses. This is all first semester or basic computer classes everyone has to take in college.
Even though 64-bit is the next big step in smartphone evolution you wont see a night and day difference right out of the gate. The OS, the apps, the UI elements all need to be written and optimized for that architecture. The Note 5 and the S6 will almost certainly have 64-bit processors but that does not mean that suddenly the Note 4 and S5 will be obsolete overnight. If you upgrade every 2 years then the Note 4 should hold its own during that two years.
If the nexus 6 won't come with 64 bit then it's not that important for android right now in the early stages in converting to 64 bit. Android L is just a building block for what's to come.

No that's not even close to correct.
32 bit and 64 bit have to do with how much memory the processor can address in a cycle. The Amount of memory a 64bit processor can address is about 4billion times as much physical memory. 4gigs is the cap for 32 bit. Which is fine for most applications. I have not seen one smart phone that has that much ram, so at the moment there is no inherent benefit to 64bit processing. Just because the memory addressing capability is there, doesn't mean we can or are going to use it.
https://www.youtube.com/watch?v=KgiMzKb8dD0
You really won't see a benefit from 64bit in any device until they start using > 4gigs of ram
Not even an issue until the next, or even the next next, upgrade.... Let the community catch up.
Unless you need to be on the cutting edge... Like the saps that bought into 4k with the lack of 4k programming.

32 bit vs 64 bit is about bus between the CPU and RAM. This is first semester computer science topic. Everything you talked about is about how it's implemented. I don't know why 4GB of RAM is the minimum of RAM for 64bit systems. I assume it's about efficiencies over 32bit systems. But nonetheless, it's about how much data can be transferred to the CPU at one time.
It's only a matter of time before mobiles devices have 4GB of RAM.
IYet, we all agree, it makes little difference until the applications, and OS, are written and designed to make use of the 64bit architecture.

It really does have to do with RAM though, for a couple of reasons. First, having a larger integer size doesn't really equate to processing things faster in most everyday applications. If you were working with really large numbers it might, but in general it's not really a big draw. Numbers under ~4 billion will process just as quickly on a 32 bit machine as on a 64 bit one. The big draw of 64 bit is definitely being able to address more memory.
Here's the second reason 64 bit matters in regards to RAM: in 64 bit, everything is bigger. Your pointers in memory are now 64 bits long instead of 32 bits (taking twice the space). So are integers. When an application that was 32 bit is recompiled to 64 bit, you can as much as double the amount of RAM is uses while running, even if nothing else changes.
So for me personally, if I don't have more than 4 GB of RAM on my phone, I actually don't want 64 bit processors or applications, because the RAM that I do have is going to be used up more quickly by the larger pointers and integers being stored. I'd personally want to stay away from it until I have a phone with more than 4 GB of RAM, because it's not until you hit that point that 64 bit makes much sense.

Again, it's because 64 bit applications can take as much as double the amount of RAM when they are running due to those larger pointer sizes. If you have a small amount of RAM, you do not want to waste it holding large 64 bit numbers. You want to wait until you have an actual need (such as having more than 4 GB of memory, which is the maximum a 32 bit system can address) before you make the jump to 64 bit. Otherwise, you lose more than you gain.
I'm not necessarily disagreeing with you about the need for RAM in the 64bit architecture. I'm not a programmer, and I know even less about low level programming, which is where more your arguments hold.
With that said, you have implied that it's possible to have 64bit system with less than 4GB of ram. You explained there would probably be more inefficiencies than the benefits gained from being able to process more data at once or at least the system would not run in the most beneficial ways for the end user.
Thus, I still hold big deal about 64bit system is about the amount of information that can be processed at one time. In tech today, it's not really about clock speeds any more. It's about the number of cores and bus size. RAM is important, but not they key, in that it's needed to supported these keys.
In this debate, obviously we may be arguing which came first, the chicken or the egg. We could have more than 4GB RAM in a 32 bit system, but what benefits does it hold? Yet, without the RAM, what benefits can be had from a 64bit system.
Personally, I would like to see a nice otco-core device. I do find mobile chipsets quite fascinating in what they have and can do versus PC counterparts. I just wish, in general, they put a little more GPU power in general in the mobile chips like NVivia does.

Snapdragon next yr will release an octo core 64 bit. The processor for the note 5 will most likely be the sd 810, octo core,64 bit + 4 gb of Samsung's newest ram. Also the screen will probably be 2k again, but even more perfected.

I'll most likely skip the Note 5, but will probably go Note 6, assuming something, I find, better doesn't come along. I could always use some more screen real estate and some true multi window action like the desktop/laptop OS gives, What can I say, I'm quirky in my demands, and maybe, just maybe, unrealistic is useful features for Joe Public.

Another tech question

OK, the big deal the last year was Apple pulling out a 64 bit chip.
Android is yet to catch up really.
My question is, are the differences between 32 bit and 64 bit huge or more a advertising gimmick?
The reason I ask is I read an article on an android site that was trying to say the biggest deal of going to 64 bit was the ability to handle over 4 gigs of ram.
I prefer objective answers so is this correct or is there a lot more to it?
Yes, the maximum amount of ram a 32bit processor can use is 4GB where a 64bit processor can handle more than 18 billion GB of ram (though you're not going to get that in your home pc, let alone your phone) . The big difference is the amount of bits per second the processor can calculate. It can make a huge difference if you take advantage of the ability to use more ram. As of right now Android for the most part is a little behind as far as the 64 bit processor goes but I believe there are already a couple phones that just came out with a 64 bit processor including the note 4 with the Exynos 7 Octa processor. Another thing to note is that Android version 5.0 "lollipop" supports a 64bit processor, so 64bit Android devices will be coming fast and furious. Once they begin to be more common Android phones will quickly pass Apple again in this area because they will take advantage of the ability to use more ram where as Apple has had the 64 bit processor now for a while and is still only using 1GB of ram in the iPhone 6.

+1 with what Thrill3d said. Another thing to keep in mind is that a 64bit processor and architecture doesn't in and of itself make for a faster device that the user can tell/see. The firmware and software (apps) that run on that device must be 64bit also before the user sees a notifiable difference. I'm not aware of any 64bit Android apps available right now and that's because there are no 64bit Android phones available in the US. You can run a 32bit apps (for the most part) on a 64bit systems, but you can't run a 64bit app on a 32bit system.
Thanks guys. It is crazy to me that the Iphone 6 has a 64 bit chip and then throw in an anemic 1 gig of Ram.
If I am not mistaken Android had phones with 2 gigs in 2012

I think the rational is that Apple has far better software to hardware integration because of the closed eco system. Whether or not that translates to better performance is highly suggestive. My note 4 hauls ass and is a beast.

The iPhone has to only do the same thing it did for the past 5 years. It's basically been the same phone and same os(minus minor changes). I'm not surprised it only needs a gig, it can't multi-task.
As for 64 bit. For Android it's going to change everything. Not just amount of ram. There is a new type of internal memory coming out called ufs that is no longer going to be an emmc variant. It's going to be similar to the solid state flash memory in ssd hard drives. The real advantages are it's more than 2x-4x faster than the fastest emmc(depending on the ufs version) . And the real beauty is that it can read and write at the same time. Emmc can't.
There is also better and faster ram technology that will be available.
But just like 64bit did for the pc it allows for better multitasking which is where android shines.

What version should I Buy?

Hi, I would like to buy the cheap version (2GB RAM 16GB ROM) but I am afraid not to have a community to help me to "improve" it.
What I need is basically some future update and very important be able to root it.
What do u suggest?

Why?
PS: I had to edit it cuz it missed "rooted".
GSM-Arena says the minimum RAM is 3 GB and the minimum storage is 32 GB, max is 4 GB and 128 GB and that's what I relied on. But then somewhere else I saw the specs you mentioned. I know Android hasn't used SD card memory well in the past. Music and apps and DRM-protected downloads were tied to internal memory and so 32 GB of internal memory was a minimum for me. But since Marshmallow those limits on SD storage are (supposedly) lifted and/or debugged.
So, I dunno. Try it, buying from a place that allows returns, and post what happens.

I'm not going to root mines any. But I haven't found any support forums. But I'm sure it'll happen
I would go with the 32 GB version as youâ??ll get 1 extra gig of ram. Miui used quite a bit of it. I run mi max with miui 8 beta. Phone has been on for about a day. And I've got about 600 GB of ram free. I don't really use ram cleaner as it can mess with Androids memory managment. With two gigs of ram I think there will be more apps that get purged from memory i.e worse multitasking. Also the extra storage is kind of sweet.
I would not go for the snapdragon 652. Even though its a beast. Remember that its a bigLittle SoC. So during normal operation the 4x a53 cores will do most of the work. The two extra a72 cores wont really make that much of a difference. Games are still single threaded.. The only motivation is the 4gb of ram and the bigger e-penis.

Is there any chance for 64 bit?

Is there any chance of 64bit OS on future official major updates?
OR
Are there any developers who are working to make a 64 bit OS ROM for the Z Play?
Though the hardware is 64 bit but does the Z Play have ability to run 64 bit OS or it can run only 32 bit OS because of 3GB RAM.
Help will be appreciated!

The mobile industry moved to 64-bit processors a couple of years back.
So, pretty much all new mobile processors will be 64-bit, and that includes the Snapdragon 625.
However, as you would be aware, the key benefit of having 64-bit processor is to allow a larger address space, and by extension a larger RAM.
However, the Snapdragon 625 employs a 1x32 LPDDR3 interface at 933MHz. Therefore, the theoretical maximum RAM that it can support is up to 4MHz
In conclusion, while you may have a processor capable of 64-bit execution, the RAM is limited to a max of 4GB.

Hmm, RAM should not be 32bit/64bit. I mean, could be from addressing perspective but would be weird to use 64bit CPU, especially SoC, without ability to address memory the same way. But on another hand, could be. Qualcomm may have generic CPU design and pack with cheaper memory...
Interesting discussion, indeed
While this does apply to everything - 64 bit OS's are generally targeted to systems with 4GB of RAM or more.
The 64 bit instructions/code are actually larger as well as they still need to contain a copy of the 32 bit code for backwards compatibility.
What this means is that while running a 64 bit OS >may< allow a phone to run faster, do more, address more memory, etc - it NEEDS more RAM and storage to be able to do this effectively.
So if you did run 64 bit on the phone - it could be slower since 3GB of RAM may not have enough memory to keep up.
I would have to assume that Motorola/Lenovo may have done some testing on this before making their choice - it's not like the 32 bit OS was cheaper then the 64 bit OS. (but RAM does cost...)

That would be a nightmare, like trying to put a scooter engine into a semi - sure you could do it but it would be pointless if you wanted to get anything done.
Agree with your previous post except "they still need to contain a copy of the 32 bit code for backwards compatibility". AFAIK, 64bit apps do not have 32bit code. That would be crazy, each application will be more than double in size. Rest is true, CPU instructions are usually larger, registers have double size... I remember very well when desktop switched to 64bit. People got excited, everyone thought that more is better but depends of the app, could be opposite.
64 bits make sense when big numbers have to be processed. Very simplified example, 8bit CPU can do the math of bigger number than 255 (2^8, 0-255) but has to do that in more steps, more instructions, more access to the primary memory... 16bit CPU can do the math of up to 65535 (2^16) with, let say, one instruction. For bigger numbers, again the same approach with subroutine. You got the point, more bit CPU, faster for bigger numbers.
But 32bits was more than enough for years on desktop, 64bit came and used mainly to address more than 4GB even 32bit CPU can address more than 4GB as well. Not as simple and fast as native 64bit but it can. Even 8bit CPU can address more. Early 8bit computers (ZX Spectrum Commodore 64...) were 8bit and it was normal to address up to 64kB (don't laugh, 64 kilo bytes ). In some variant even more, 128kB or more.
After all, question is do we have to process such huge numbers on the phones? Usually not. Even on desktop, usually not. Yes, games, virtual reality and such need a lot of processing but that's done on RISC based GPU part.
64 bit SoC and OS is mainly gimmick.
The biggest benefit to running 64-bit OS on MZP would be the ability to use the new Google Camera with HDR+.
Moto Z users are reporting a noticeable difference in camera quality. I wish we had that too

Yeah!
I want the google camera and dolphin emulator.

Let's keep the comments RESPECTFUL and regarding the title of the thread. Profanity and personal attacks will NOT be tolerated.
This is a courtesy warning, please do not let it happen again.
Thanks for your cooperation.
Guyz, those who were telling that 64 bit is not possible in 3gb ram and Snapdragon 625, what about the Redmi 4 with 3gb ram and Snapdragon 430?
