Develop Bugs

[Q] Please answer me

Hi xda developers , I am pleased to be here
I have only one question and hope to get an answer for it
you know the Samsung Galaxy S4 came with new Smart features like Smart Scroll , pause , etc ...
is these features related to the S4 hardware itself , or just something is concerning with it's software?
if that related to it's Hardware , so no way to port that to another android device like S3
but if that related the the Software , so all android devices will get the smart features which is the S4
the S4 android version is 4.2.2 as you know , and S3 has now 4.2.1 and 4.2.2 , so the software is the same
so why the smart features is not working on S3? I know the 4.2.2 is just leak for S3 and not official but at least has the same features of S4 except the smart features
the second thing is if tat related to the S4 front camera and the proximity sensor , so it must work on S3 because S3 has the two things
I sow in android 4.2.1 which on the Samsung update site GT-I9300 ILO I9300XXUFMB3 after I flashed it on my S3 when I long press the smart stay icon I get 4 features :smart scroll , pause stay and rotation
but scroll and pause is not working , why that?
and I found a custom rom in this nice site called "Glamour S4" with all S4 features , but just icons and text , not working.
so is that features will not work in S3 or what? because if it will not work , I will buy S4 , but if it will work, then when that and with custom rom or official ?
please help me because I am from long time ago I am searching for that
by the way!
some developers in Israel name" Umoove" talked about Eye Tracking technology and I watched a video which shows the eye tracking seems to smart scroll working on s3
and some other teal developed same technology called "TheEyeTribe" but nothing is out yet
so please answer me if it will run on S3 or it is not available now?
thank you

That's a lot of questions, but it boils down to one thing: Will features from the S4 be ported to older-generation phones (S3, S2, etc.)?
The short answer is: most likely, eventually. Our Devs here are really good and most likely will be able to get most (if not all) of the features working.
The long answer is that there are quite a few hardware differences between the two devices, and while they both have "proximity sensors," the way the software interacts with the hardware varies greatly between the two. Think of it this way: Apple OS runs quite well on Macs, but if you try to install it on any PC (even high-end ones), it most-likely won't work (at the very least certain features won't work). You can make the argument that both have screens, hard drives, video cards, webcams, etc, but the software has been written specifically to interact with the hardware it was designed for: Macs. The same principal applies to our phones. While it's not impossible, it would take a very intimate knowledge of both the S3 and S4 in order to do it. It would also require extensive testing.
Sometimes porting to a new (or old) phone is (relatively) easy, such as with CM or PA Roms. This is because their source code is readily available and there are many Devs willing to help our porters.
Other times, it can be a difficult and arduous process. You can ask CNexus about it, as he has been creating a Sense 5 Rom.

They won't need to be ported, Samsung has anyway said we will receive all the"features"of the s4 with our next update, only time will tell when that's gonna be

Which model is more dev friendly?

Looking for a new tablet and I know that for my old one it didn't get a lot of development love because it has an exynos processor in it. Is this still true? I won't be using it's phone capabilities but will get the snapdragon if i have to if it means more flashing fun because i cannot survive on stock.

Exynos always lags because Samsung goes well out of their way to sabotage devs. Knox, horrible bootloaders, drivers, plus a bunch of hardware blunders (wipe emmc bug, HMP booboo) tend to deter devs from supporting Exynos but iirc worst is Samsung doesn't release source code in timely manner.
If you have other options ignore the Exynos. The Tab S has such a nice screen I couldn't resist

Whoa. Sounds like this tab have a lot of problems. I think I will hold off and see what the new quarter brings. Z3 tablet maybe a new nexus 10. Thanks for the info. :good:

The new Dell with a Samsung AMOLED screen seems very interesting...

This tab doesn't have many issues at all. The rant above appears to be a general rant and even included issues that are outdated and nothing to to with this device !
If all you care about is dev support, then suggest a SD powered device, but this device kicks as in so many areas. ; )
Sammy is quite good with OPEN SOURCE requirements, but can be slow occasionally. Some OEM don't adhere to the GPL requirements at all. Try building a lenovo kernel, they won't even supply the defconfig to compile it !
The thing is, .... With development here, instead of whining, many users have got off their lazy ass and contributed themselves :thumbup:

i will check it out but I'm not sure how much dev support a product from dell will receive. Not much I'd imagine.

I had a bit of time to look through the forum last night and it appears this device isn't getting much support at all in any models. I know it's still new but even the 705 which i have the opportunity to buy and supposed to be dev friendly isn't getting much attention.
I don't think it would be good for the community if I started building as a lot of bricked devices would happen. Lol

the tablet community is too widespread. too many device around and low dev support in most of it.

+1 although in Samsung's defense the touchwiz on the S is their absolutely best so far and really good stock with Nova launcher.

General rant was inspired by owning all Samsung's flagship devices since the original Galaxy S, plus trying to build BeanStalk, LiquidSmooth and Gummy for the T700
Past exynos disappointments include the Tab 7.7 (no firmware support from Samsung a few months in) and international Note with the emmc that self-destructs randomly. Great hardware, lousy firmware/drivers/documentation.
Thanks for your kernel too.

Lack of Development

So what is with the lack of development for this phone? It's really making me regret getting it.

so get a nexus...
or develop for the device if there is a lack of development issue.

Always research a phone before you get one, as some receive more dev support than others. The edge variants also probably won't see much. You don't really get samsung phones to get cm these days.

I would love to develop but I would have a lot to learn. Maybe someone will trade me for a Nexus 6. I would be happy with root and a custom recovery but I can't even get that working, recovery won't load it just hangs every time.

At present there are obstacles to tackle as far as development is concerned and when that is sorted out you will see some development.
Or maybe Samsung is aiming for a different user crowd, like the type that get a high end phone that works all the time, without apps fc' or freezing displays and they don't have to reboot it several times a day or nandroid back because they can't hear or be heard by callers.
I'm totally happy and satisfied with this S6e the way it is, and Samsung has done a superb job putting this premium phone together.
Pp.

Regarding Aosp on GS6/E it's going to be a long time/never until we see aosp on the device, the reason development is non existent is because of Exynos, Samsungs SoC. Samsung refuses to give out it's source code for Exynos for obvious reasons and without it's source code, building aosp is no easy task. Some devs have built aosp for Samsung devices based on Exynos before but not fully working/stable ones. All in all, you'll be waiting a while.

Are there really zero custom ROM's for this phone yet ?

I'm not directing this at the great developers here, but I'm more confused or wondering what's up ? This phone is Google's flagship stock Nexus device, THE developer phone. The Pixel 2 was released two months ago, and there's not one custom ROM yet. I find that shocking and asking what happened ?
I've owned most Nexus phones in the past, and by two months in there'd be a ton of ROM's available.
Again I'm not trying to be an ass asking this question I'm not looking for ETA I'm more very confused or am I missing something why development doesn't seem to be happening like in past Nexus phones?
Or is there another forum outside of XDA these ROM's are on that I'm not aware of ???

A few roms are coming to this phone. It's just slower because of the dual partition stuff. Think DU and Pure Nexus are planned.

You must also remember the pricetag on this device, not everyone is going to jump on this device right away, but like the above comment said, there are ROMs in the works.

A lot of devs weren't building because we didn't have a stable TWRP.
Looks like one just dropped

All of what's already been said here.. plus.. this phone is so darn stable and amazing bone stock that it's unbelievable. I have had every single Nexus/pixel and HTC device since I don't know when and there was always some reason why you badly needed root and a custom rom.... But with this... It's so good I haven't even unlocked the bootloader yet! Kudos to Google for sure!

OnePlus has screwed it up for everyone when it comes to custom ROMs, the phone is half the price of top flagships and just as good so thats where most of your development is

Agreed that OnePlus has sucked away a lot of developers, if not the majority of them. OnePlus 5 / 5t is almost half the price of the Pixel 2 XL, plus it seems even easier to developer for. I mean go in the OnePlus 5t forum and look at the development, phone hasn't been out one month yet, and it has a bunch of ROM's and Kernels.
But I prefer the direct from Google updates and long term support by Google, plus the extra features on the Pixel 2 over the OPO, and am happy with my purchase, but I am concerned that there is not even one single ROM released for the Pixel 2 after two months.

Good find, looking forward to try this out when it's ready.

Development for the J4

Usually when a New J series is out, our community of great developers are all over it finding ways to root and making rooms. Since the J4 has been out for a few months there hasn't been any sort of news or updates. Are there any teams working on it?

I'm afraid that the possibility is slim, since the J4 is not widely released (do correct me if I'm wrong) in the US, UK, or other big-market countries, but rather released in smaller-market countries in Africa, Asia, etc, and even so released rather quietly w/out major press releases. So unless the phone is widely released (relative to other Galaxy phones out there), I'm inclined to believe that such teams would have little to no access to the J4, and thus no development to progress for it.
(Believe me, I'm remaining optimistic that at least an unofficial recovery might be on the works, but there won't be much progress unless the J4 is more widely used/picked-up)

Or, you can learn how to do it yourself.
Not the TWRP porting, but you can definitely MOD your stock ROM to add features Samsung annoyingly disable for not being a "premium" device.
You don't need to know much of coding, you can learn as you go. When the J2 Prime was released (and even to this day) there aren't any custom ROMs so I had to teach myself and I've accomplished great things
Just wait for TWRP and then the doors will open, you'll see

Huh, that's interesting; I'll surely take a look.
Could you further elaborate on the "features" that Samsung disabled? (I don't use a lot of Samsung G's built-in features, so I'm not too knowledgeable on such; tried Google-searching, only came up w/ disabling apps, so that didn't really help...)

For starters, things like edge screen or scroll capture (things that I use a heck of a lot)
I found it funny is that all it took as to change a bit of code here and there, add the right apps and edge screen was working perfectly on the J2 Prime (a very low-end phone).
Samsung went out of their way to delete this feature which is pretty ridiculous if you ask me.
Themes were also disabled for this device, but after reading a few guides I was able to implement a ROM control that allows the user to change the color to their liking
The dev community is always willing to lend a hand, just as long as you're not lazy and expect everything to be put out for you.
I feel the J4 can make a dev out of someone looking to add more functionality to their device (the J2 Prime made a dev out of me )

Ok, so the TWRPBuilder's experimental TWRP build (huge thanks to @yshalsager for this miracle) is on TWRPBuilder's site: twrpbuilder.github.io/downloads/twrp/
Like any TWRP builds, there is ABSOLUTELY zero guarantee that it would work (I tried the first one & it didn't work, haven't had the chance to test the latest one yet)

The J4 uses identical chipset as the J5 prime G570F/M/DS.
I have both and they are great phones for their segment.
Sadly neither are well supported by ROM developers, due to the Exynos chip, I think.

@yshalsager did a test custom recovery for J4 (via TWRPBuilder): https://twrpbuilder.github.io/downloads/twrp/
Have been unable to test it atm (stuck in 7-day jail); if you want to have a go at it & let him know the results, go right ahead!

but first we have to unlock oem.but the problem is no oem unlock in the settings

Yeah that's the 7-day "jail" I was talking about - theoretically you have to leave your phone on non-stop (no reboots, no shutdowns) for 7 whole days straight, then the OEM Unlock option should become available in Dev Settings (it's a confusing security measure by Samsung on Oreo devices)

any update guys? im really bored with this phone now

up

guys can we root our device j4 using magisk?
