Android 2.3 port from Nexus S to Galaxy S?

Hey guys,
what do you think, is it possible to port the Android 2.3 Gingerbread from Nexus S to our Samsung Galaxy S. Because it has a similar hardware!
/Discuss

You're fast , just wanted to ask this. Hope some legend dude will do this.

Theoretically it should be very simple to port the software. The only difference I can see from a hardware perspective is the NFC chip which simply needs to be disabled in software, and the missing search button which will need to be mapped to a menu long-press.
I did some work on the NITDroid project back when I had an N900, and neither of these is particularly difficult to do.

will the iNAND be a problem?

Supercurio says the devices use different types of memory.
Might be a bit of a problem

i can't see any reason we will have issues bringing it to the galaxy s line, especially if its the same SoC... and hardware, gps might be different, but thats a huge bonus anyways

yea the Nexus use the 16gb iNAND...

Since Samsung closely helped Google at making the hardware, hopefully we might have a quick 2.3 Samsung version for our devices
Which will then be easier to bring down to stock with the Cyanogen team progress

It must be far easier than a sense port or even cyanogen port.

One thing that also caught my eye was, that the video recording isn't HD... probably to not throw away boatloads of RAM for the camera...

I wouldn't bet on that. If Sammy released 2.3 in short order for the SGS it would cannibalize Nexus S sales. The aftermarket community is still the best bet.

GPS is the same! Both using A-GPS Chips. The NFC Software must be Disabled, Bluethooth Updated to 3.0, Nexus S has only 2.1 and Video Recording Updated to 1280x720, Nexus S had 720x480

This a premature thread. Once a dump or aosp is released only then can we begin to do something about it. Till then this is a discussion thread and not related to development. IMHO

What about rfs? Im sure google is not using it. We will have to work that out as well.

2.3 SDK is out so I see no problem in getting gingerbread.
Whether as a port from the NS or a homebrew I don't really care.
All I want is the integrated SIP client. Been missing this since switching from my Nokia e90 Communicator to Android 1 year ago.
I am interested how the nexus S fares against a hacked Galaxy S, don't think it will be any faster!

Everything is virtually the same.

I call up one the powers of the all powerful XDA to port the N:S for all the SGS's that are out there, so we can forget about samsung roms and use a normal google one

The Nexus S doesn't seem to support an external sd card. Likely another problem?

Looking For Tablet ROM With More Complete S-Pen Support

Hello. I have written an app that helps to improve the accuracy of the S-Pen. It works only on Note phones because Samsung has compiled some S-Pen device driver interfaces out of the tablet ROMs. It is not clear why they did this. I have asked Samsung but gotten no replies. I have confirmed that parts of the kernel code is commented out in the open source kernel code (and you can see that some of the interface files found on phones do not exist on the tablets). It seems that the tablets suffer from the same issues related to the S-Pen as do the phones and I have many people asking me to make my app work on their tablets. I cannot do so with the stock ROMs because of the missing interface files.
So I am wondering if there any non-stock ROMs in which the S-Pen is more fully supported. The missing files are located on my phone in /sys/class/sec/sec_epen/ and the two files I need are called epen_hand and epen_rotation. If anyone knows of any ROMs for the S-Pen equipped tablets that provide these interface files, I would appreciate knowing and may be able to direct some folks to using them.
Thanks

It's going to be good if we can use Pen in our tablets
but i guess you need to post this Thread In Developing Sector because what you need is Developing general is just for simple Questions and things like that
I hope you can do it ^_^

Sailfish OS for Nexus 6? (on multirom hopefully (so talking to you as well Tassadar))

I've looked into porting this myself based on the instructions provided from Jolla's website (found here https://sailfishos.org/develop/hadk/), it seems pretty straight forward. However apparently (according to Jolla) it cannot be done on a 32bit system even if I use Linux (which I do). I was wondering if anyone has entertained the thought of porting it, as there's a 2.0 version of the OS out now and I really want to try it. Kind of missing it from when I used to play around with it on my Nexus 5.
Conversely, if anyone knows a workaround to using a 32bit system, or if they have knowledge of it actually being possible on a 32bit system (could be Jolla is being overly cautious in requiring a 64bit system, but I believe it has something to do with working with MER), your advice would be forthcoming. Willing to put in the work, I just apparently don't have the tools according to Jolla and can't afford a new computer. My two Linux systems (one running Kubuntu, one running Backbox) are very capable. This is just the only prerequisite I don't meet.
As far as multirom, I'm curious if anything special has to be done besides the instructions from Jolla to make it compatible as a secondary rom at least.
Thanks in advance for all responses and patience. I may be a low contributor/noob to this site, but given the proper tools and advice I think I can pull it off. I haven't found anyone that's working on this for the Nexus 6, so if there is someone, obviously I'm willing to help or test.
Special note to Tassadar if you happen to see this: Multirom is the best thing that's happened to android since custom kernels. lol Big ups for your creation!

Awesome I hope more are interested too, I don't have resources to help either besides a test.
I can say that I have never been more impressed with a UI than the one I flashed on my n5 called Sailfish, Same as you I think.
To others of you have what's needed and haven't seen the ui please check it out. I thought it was minimal, sleek, and I believe it used mostly touch commands.

This thread is kinda in the wrong forum. Should be in q and a or general discussion.
But yes I would love to see this on my phone

First, don't post Q&A in development forums. Second, the first step in the guide states the device must be officially supported with CM 10.1.x, which this device isn't. Unless they just haven't updated their guide this will never be possible until it's updated to something based on Lollipop.

Please read the Forum Rules on posting, Moved here...

FYI, android also has needed to be built on 64 bit only for several versions now. I think since Ice Cream Sandwich.. 32 bit just isn't cut out for it.

Sorry to raise this thread from the depths, but why haven't any devs pursued this?
I would love to try sailfish os on the nexus 6!
A $200 budget device was released just a few days ago in India that runs sailfish os natively, which is why i started looking into it for shamu.
Thought about picking one up, but the cellular bands aren't great for use in the U.S., and spec-wise doesn't hold a candle to shamu.
Through a little searching, it seems one person with the handle of mad_fitter on merproject irc attempted a port back in March, but never finished it afaict. Apparently, the fact that he had an intel chip prevented him from completing the final steps somehow...

This is an old post, but i love my phone and have dabbled with sailfish os before. If it could be ported that would be great and according to the the HADK documentation you can now use a cm 12.1 image instead of 10 to build it, whih was available for shamu. Someone could get the image from archive.org and use that. I have no experience with porting roms so i wouldn't be able to do it but if someone else could it would be great for the few of us that want it.

I would love to try this on my shamu, as well.
Has there been any development on this?

On reading up in the Galaxy Nexus forums, I saw that the TI-OMAP 4 was not supported in AOSP Lollipop and above. Is this why our OMAP phones perform poorly on ART based ROMs, while ROMs using the dalvik compiler are smoother? In AOSP Nougat, the Snapdragon 800 and 801 chips using the Adreno 330 GPU are no longer supported as well. I guess my question is if it will it be possible to reverse engineer OMAP-4 drivers for Nougat that can support the new surface view texture renderer?

I MIGHT be possible to support it, but would take a bit of work, offloading that stuff to the CPU (which is just what we need, right?) and all of which is above my skill level.

The performance problems are probably a mix of slowish eMMC (have to load the precompiled ART files, and they're not exactly tiny), lack of main memory (ART has a bigger memory footprint), and an unsuitable CPU that was outdated when the phone was built, nevermind nowadays. The latter two are what seem to really kill us in CM13; if we're not stuck reclaiming memory, we're saturating the CPU : \
Having Motorola stroll in and develop some up-to-date, optimized drivers sure would be cool, though...hardware is hardware, but good firmware can make a lot out of little.
Nougat is apparently taking a step back and re-introducing JIT execution...so if our resident maintainer does somehow pull off yet another miracle and we get CM14 on here, I'd expect less I/O and memory pressure at the very least. The stock partitions would become viable again too, what with /data/ not being clogged by ART precompiles, and being able to run off them might also offer a (small) performance increase. /system/ is gonna be a tight fit, though...
But using drivers built in two previous, different eras of Android, most of which were for another device...seems like it's gonna take some serious work.

Galaxy Nexus has Nougat!
MWisBest said:
Nougat build is up. No, I have not died, and neither has the Galaxy Nexus.
Decided to take an extra couple days to get this build stable rather than rushing out something that boots and does nothing else, sorry for the delay.
I can't verify the full functionality of the RIL since I don't have a SIM in my GNex these days, so let me know if there's any issues with that.
Everything else should be working well though.
No idea what to do for GApps at this time. I haven't tried them yet.

As usual this was a team effort. @Ziyan helped, and @Hashcode (who I thought had died) helped as well.

Last time i talked with i Dev about Andoid 7 on the Droid 4, i was told that it would not be possible because of SELinux. But that Info is almost a year old. Maybe someone has more up to date information about this.

Thanks! Maybe we should ask @stargo about it. Although, I know stargo likes to surprise people with a new Android version.

Really hoping this old beast will get CM14 due to the coding magic of stargo or some other guys out there.
I recently aquired a completely new Droid 4 from a Verizon reseller in mint condition. Now I never want to live without a slider again!
It is a bit slow, gets hot sometimes and becomes pretty much unuseable with Google Play installed, but who needs that stuff anyways.
Can keep me warm in winter and after replacing stock apps with Naked Browser and Simple Music Player it runs well and fast.
Please don't let this slider die. The only alternative to this device is the Photon Q and this needs to be soldered due to the missing SIM slot.

Bro i think it will have a cm14 for the droid 4
Bro, there say that it is official for the droid 4 to get cm14 check on gammerson .com

Hi folks! I had some spare time to setup CM13 build tool chain and - maybe too late for @Septfox - I made a custom kernel with LMK accounting for swap memory, i.e. LMK does only consider memory pages as free which won't require swapping, now. In order to not spam this thread anymore with LMK issues and memory tuning, I created a new thread: http://forum.xda-developers.com/droid-4/development/wip-custom-kernel-lowmemorykiller-t3470411

This is cool. I'll test these out here as well. If things look good I'll see about getting LMK changes added to the cm13 kernel and upcoming cm14 kernels (work just began).:good:

Not really confirmed (as in no promises it will ever be fully functional as of yet). Just started working on getting things compiling. After that, it's along ways a way from anything usable as there are some new hurdles to overcome thanks to additional lock-downs on SE Linux. So yeah, :fingers-crossed: is right.

New to Note 5 Canada, Linux root questions + VR

Hey all, so I've been trying to dig around a bit on the forums to find some answers, but alas, couldn't get specific enough information, so thought I'd just make a thread of all my questions lol.
Currently using a Note 5 SM-N920W8, 6.0.1, Stock.
I use Linux, and have no access to a Windows machine, and no desire to make a windows VM plus I doubt I could free up enough hard drive space right now anyways hahaha.
I also DAILY use my Samsung Gear VR.
---
First question: Is there a way to root my phone given my current setup?
Second: I DID read that the gear VR won't work with most custom roms (Like AOSP based ones). Any custom roms that DO WORK (Must work 100% without having to jump through a billion hoops to make it function) with the Gear VR?
Third: Any recommendations of any kind, since I am new to this device, would be appreciated!
<3

I will let someone more qualified than me answer this but I will say I'm glad my Note 5 is my third phone not my main 2 as there is no updates on ROMs for this phone I haven't see anything new in months lol
Sent from my SM-G935F using XDA-Developers Legacy app

Even the stock MM Rom runs nice and smooth for me. I just want to root at the LEAST so I can get Viper running...But, I wouldn't mind a better kernel / ROM either, so I can increase my battery life, tweak a few things.
-- Also, Just realized I should have maybe posted in Q&A Rather than general. If a mod wants to move this, cool by me!

bump.
Anyone?
