Hello XDA I am using Samsung Galaxy j4 with Samsung Experience 9 (8.0 Oreo).
So as you know the Samsung TouchWiz rom is heavily combined ROM and it has a lot a lot of useless apps and files in system in compression with aosp ROMs the aosp ROMs has a better general performance so can anyone tell me what I can delete
And what I can't delete from system folder and useless lib files as Knox services which I don't really think it really has that security importance.
And thank you for your time.

hey @all,
at first i got the sgs. After some month i root it and later i flashed cm7 and then cm9 and i loved it.
now i have the sgs3. and the stock rom is ****.
its laggy, i miss a lot of features and so on. so, at the moment i have a view on cm9 on sgs3.
and when i read some posts and known issues i thought about some things like:
- TVout doesn´t work an should never work.
so, the cm projekt is open source. but i can update the cm os with some original files from samsung to solve the prob (for me). right? or is is not so an easy way?
- radio doesn´t work
so i thougt i can copy the radio app in /system/apps (i write down the path out of my mind)
Some samsung apps has nice features (like the video player).
Can i use the app like copy it on the cm os?
the main question is, can i customize the cm os with original samsung apps and samsung configs, so that all thinks will work.
is there someone who has/will create some packages for that?
great thanks for replys

The answer is largely no.
Most Samsung apps rely on the Samsung framework which only exists in Samsung official roms, this is almost impossible to port into an AOSP based rom like CM9.
However there is a project underway to port important/useful features from stock roms to CM9, this includes a lot of TW features (but not smart alert )

Warning
Before flashing a new ROM, ensure that the model of your Galaxy S4 is correct in the procedure: GT-i9500 for the standard version, and GT-i9505 for the 4G version. Flashing the incorrect ROM on your smartphone could brick it.
PAC-Man 4.4.2
PAC-Man is one of the custom ROMS that is gaining a lot of popularity. It integrates many functions from ParanoidAndroid, CyanogenMod and AOKP, so not only does it have a lot of options, most of them have also been improved on. The version of the Galaxy S4 i9500 is based on Android 4.4 KitKat and is currently in its alpha phase, though some wrinkles still need to be ironed out. The last official version for the I9505 is based on Android 4.3, but it’s more stable.
Lidroid allows you to keep the TouchWiz theme for those who are used to it and don’t want to completely eradicate it. Lidroid is based on the official version of Android 4.4.2, is deodexed, and integrates all the base Samsung functions, along with a theme editor and an excellent file explorer. If you would like to step it up a notch without significantly changing the entire user experience, then Lidroid V2.0 is for you!
MIUI
You may ask why we mention MIUI, a custom ROM that almost everyone knows about? That’s because, on the Samsung Galaxy S4, the size of the screen and the MIUI color management work really well together, as if the ROM was made for the smartphone. If you like big icons and the absence of an app drawer, MIUI might just be your thing. The community behind this ROM, which was first developed by the Chinese manufacturer Xiaomi, is very large and extremely active.
Prism Barebone ROM
Prism Barebone is based on Android 4.3. It is stable and allows you to choose between either the TouchWiz or pure Android design. Pre-installed apps and other bloatware have been deleted, however Samsung widgets still remain on board. It’s like the best of both worlds. Prism Barebone allows you to choose what you want to keep from Touchwiz and what you want to get rid of.
CyanogenMOD 11
CyanogenMod has almost become a staple of custom ROMs. It’s very useful, stable and gets regularly updated. The ROM is so good that it’s almost natural to turn to CM if you don’t know what else to flash. There is version for the Galaxy S4 I9500 and one for the S4 4G I9505, both are in the nightly stage, but are relatively stable. Those who want more can turn to CyanogenMod 10.2, which is based on Android 4.3.
Hi,
I have seen people port touchwiz multiwindow (henceforth MW) from touchwiz roms of mid-level / high-level Samsung sets to low-end ones. Like there are ROMs for j7 2015 based on stock (which is NON-MW) that has all the MW features. I really want to learn how to do that.
I use MW a lot. It's not fair to bother busy developers demanding new releases when Samsung releases updates with security patches. I would like to do it myself.
So far i have discovered extra xml files in /system/etc/permissions folder and a multiwindow.jar in framework folder . But i dunno anything else that might have taken place within framework res and other jar files.
Could soneone be kind enough to show me the path to enlightenment, please.
Thanks and regards,
P. S. I tried contacting the developer, but he seems really occupied with something at the moment.
Hi,
This is my first post on XDA, so please let me know if I violated any rules of this forum.
I have observed that there is a dearth of custom ROMs for Samsung devices with Exynos chipsets in general. Since the manufacturer doesn't provide much support/update after ~2 years, i think it there should be a way to increase the life of the device.
As an example, I have a Samsung Galaxy Note 5 (SM N920G) running Android Nougat and i couldn't find any ROM with Android Oreo supporting this device.
I have no knowledge of Android ROM development, so please forgive me if my questions are stupid or too basic.
1. How difficult is it to create a custom ROM in general and does Samsung make it difficult for developers by not releasing the kernel sources?
2. If the devices share a common chipset, how difficult is it to port the custom ROM to make it work for another device? Ex: If there is a custom ROM working for Samsung Galaxy S6, how much work does it require to make it work for Galaxy Note 5 as well?
I was desperate to try Android Oreo on my device and i have some time to burn this weekend. So i was wondering if i could try and create a custom ROM for myself.
I've also searched XDA and found some guides which were written for Marshmallow/Nougat. I am not sure if the same methods can work for Android Oreo as well.
I am looking for any inputs/suggestions and any sources you could point me to in my attempt to learn.
Is it possible to port some particular feautres of any given Rom to another Rom(say Stock android rom) keeping all the properties of the Rom remain same.
Explanation:
Let us say we need some features of a MIUI and some other features of EMUI, Is it possible to add those features from those roms to the original Stock rom or Some other Roms of the mobile.
Also Is it possible to make the Rom of some other mobile (which has similar specs that of my mobile ) to work on my mobile..
Actually I am just a noobie & newbie to the field of porting Roms, I had these doubts stuck up in my mind from long time.
Some people extract the APKs from specific ROMs (for instance, I managed to get MIUI's Ambient Doze working on a different ROM) and install them on other ROMs.
However, that isn't always the case because some mods have been built into system APKs such as the SystemUI apk.
