J3 Emerge on J3 Prime - Samsung Galaxy J3 (2017) Questions & Answers

Is it possible to get the J3 Emerge's firmware on the J3 Prime? They're the same thing, just different carrier and colors. I want to do this because of Nougat not being well optimized for the J3 Prime. It's slow, and doesn't even have a app closing animation. Pressing the home button has no animation at all, adding on to the cheap feeling. Not only that, but the J3 Prime is waaaaay slower than the J3 Emerge. Stutters everywhere. And even though it meets the requirements for the Google assistant, it's not even present on this device. I can only imagine why. I want to downgrade to marshmallow because it's waaaaay more optimized. Any help at all? I know this phone can't even be rooted, so I want to go through this process with the modified Odin.

It wont work they are different platforms and the bootloader wont let you flash it anyways. Idk why.

[REQUEST] Vodafone Smart Ultra 7 - Root

I've been searching on how to root the VFD 700 (Vodafone Smart Ultra 7) for a while now.
I've tried KingRoot but with no success. OneClickRoot doesn't seem to support it either.
I really like this phone, it feels snappy and responsive, the screen is nice and the price point even better, but I previously owned a i9300 and a Maguro (Galaxy S3 and Galaxy Nexus), and both had custom ROMs, recoveries and were easily 'modified' so to speak. They were awesome, but time has taken its toll on these devices, and they now feel slow and degraded, that's why I've upgraded to the VFD 700, but the lack of support/development on this phone is agonizing, I can think of living without my SuperSU (AdAway, Greenify) and Xposed Framework (GravityBox).
So here goes a desperate call for help, if you can help me in anyway please do, from knowledge to actual solutions I'm all hears.
*I do now that Android Marshmallow 6.0 its quite hard/inconvenient to root
*Attached goes the About Phone screen, I managed to change my screen dpi trough the Android SDK
Thanks!

Getting a Samsung Feel on 6.0.1

Hi All,
Does anyone know if there is a way to update the SM-P900 ROM but still keep full functionality for the S-Pen, and Samsung apps?
I'm on 5.0.2, have TWRP installed, and am rooted.
I tried a 6.0.1 CM ROM, but it loses a lot of the ability that the Samsung ROM has, as well as many people mentioning that it has issues with the S-Pen causing crashes.
Basically, I'd like to get the security updates, and 6.0.1 options, without losing the rest of the Note functionality, because it feels like CM removes the whole point of being on a Note Tablet, which for me is the S-Pen.
CM is fine and all, but it's always felt too AOSP for me, when used on devices like the Note series.
My Note 3 is on a Note 5 port, that allows basically everything to be modified without losing the important features, and I realize that might not be a realistic expectation on the 12.2 Pro, it seems like a waste of good hardware for the background OS not being updated yet still maintaining itself as a Note device.
Any thoughts on if this is possible, or is it simply a matter of the hardware lacking the ability to run 6.0.1 and the software lacking the compatibility?
Thank you!
This isn't likely what you want to hear. But Samsung's "feel" relies on its TouchWiz interface, which for our tablet is not available in Marshmallow. However, if you want a rooted tablet that's somewhat debloated yet still has TouchWiz, I'd recommend the excellent CivZ Lollipop. Perhaps you know of it already. If not...

Different firmware for a Samsung tablet

Hey there, I recently found out Samsung Galaxy Tab S4 will get a DeX mode and thought about how to get it on the previous flagship tablet of Samsung - Tab S3. I have one and I really think that DeX mode will be a nice thing to have on a tablet with a pen. We all know, that Samsung can add that feature later like it did with S9 camera functions on S8 with last firmware update. So there is the question: is it possible to install a Tab S4 firmware on a Tab S3? They have different screen ratio but that must be all differences out there. Maybe hardware home button also. I read about installing different firmware on Android tablets but often people said something like "the devices must be nearly identical to use the same firmware" and all that stuff. But really, the only thing that is really alarming me is the software buttons on Tab S4. I think they will float there for no reason if it si possible to install Tab S4 firmware on Tab S3. If you know something about a different firmware on Android device, please, tell me. Thanks.

It is possible to flash a firmware from a different device but they have to be of the same hardware chipset. For example, some models of US versions of Galaxy S3 can share each others firmware, but the S4 cannot use the S3 firmware.
But, generally speaking(95% of the time or more) flashing a firmware from a different device results in a hardbricked device. This is mostly due to differences in bootloader and modem. I have a Galaxy S3 SCH-S968C(Straight Talk) that can use the custom ROMs from the SCH-I535(Verizon) because they are virtually the same device BUT the SCH-S968C CANNOT flash the SCH-I535 stock firmware, it results in a hardbricked device, even though they are the exact same device.
There is no definitive answer to your question other than it is "possible" to use another firmware. But it is ALWAYS a special case scenario because you have to research the devices in question to see exactly how similar they are or are not.
There are cases of devices from one country being used in another country by flashing the firmware from the country the device is being used in, but it is not possible on ALL devices.

Galaxy S7 Performance

I currently have an S7 flat with the stock samsung oreo rom, no root or other customizations. Upon its launch, it was on par if not faster than my iphone 6s. Now, the S7 is quit abit slower in gaming and overall performance vs the 6s.
I wonder if thats due to outdated software/OS, as i understand the S7 is by default running TouchWizz? The playstore says Samsung oneUI though.
Anyway, to the question, will installing a custom rom like Lineageos or any other rom improve general gaming and app performance, or will it not make a huge difference?
I have already done a factory reset, disable apps (bloat) etc.

There might be custom roms with better performance for some usage.
But you may have to check/test several roms to find the one that matches your needs best.
Here you can find some custom roms for your device:
Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri
Galaxy S7 ROMs, how to root, kernels, apps, downloads, and mods. (Exynos)

Best to create a backup of important data on your phone. Just in case...

The launcher Samsung changed the name to One UI but you're still running Samsung Experience not Touchwhiz.
