Thank you, this is a very nice custom ROM! There's only one major problem for me. It sounds like there's some audio processing happening on this ROM that makes the audio coming out of my speaker sound a lot different compared to my device's stock ROM. It does this for all audio channels (Ringtone, Media, Notifications, etc). I disabled the inbuilt equalizer, all available audio effects, Dolby Atmos, Adapt Sound but still nothing changed. I also uninstalled packages "com.sec.hearingadjust" and "com.sec.android.app.soundalive" for user 0, but still got no change, even after rebooting several times.

I'm using a Samsung Galaxy 2017 (SM-J730F). I would appreciate it if anyone could help me with this.

The app is installed, but immediately freezes when it's opened, so no it doesn't work.

Also, the camera bug still exists. Some apps like TikTok can't access the camera at all, but Instagram, Messenger and Skype seem to work just fine. The default camera app also works without any problem (except that it freezes when you try to use any Note20 exclusive features). Face unlock also doesn't work. However, app opening speed is fine, it's better than my phone's stock ROM in my experience, it's just a little stuttery in the app launcher because of the background blur effects.

I'm using this ROM on a Galaxy J7 2017 (SM-J730F).

    • I am not responsible for bricked devices, dead SD cards, thermonuclear war, or you getting fired because the alarm app failed. Please do some research if you have any concerns about features included in this ROM before flashing it! YOU are choosing to make these modifications, and if you point the finger at me for messing up your device, I will laugh at you
    • I've put a huge amount of time and effort in this SOLO project (no other dev has been involved), so respect me and respect my work. You are NOT allowed to use this rom, its vendor or any of the other files included as base for your projects.

    • OneUI 2.5 under Android 10, ported from the SM-N980F
    • J730X supported
    • Arm64 with Treble support
    • Fully deodexed
    • SIMPLE-KERNEL included, compiled from A600FNXXU5CTB9 sources. Built permissive.
    • Deknoxed, debloated, and removed all samsung useless security stuff in rom and kernel level
    • N20 muti CSC with additional features (call recording, etc)
    • And many more!

    • All S-PEN features have been removed, don't ask for them!
    • In some phone variants, the rom could be a bit laggy while opening apps. Try cleaning dalvik&cache
    • Face recognition doesn't work
    • Updating camera app through Samsung app store will break it
    • Light in capacitive buttons for those devices with hardware buttons
    • Some 3rd camera apps like footej or whatsapp video calls don't work (this bug is only present in the A3, J7 2016 and J7 Prime). Use whatsapp business as workaround
    • FM Radio could be bugged too for phones different than the A3
    • Other inherent bugs from OneUI and/or 7870 limitation
    • You tell me

    • Current version: 1.0 (21/08/2020)
    • More info in 2nd post

    • Vendor partition is required
    • You need a 4gb system partition, so flash my repartition script if you dont have it
    • Wipe system, data (clean install mandatory), vendor, dalvik&cache and cache
    • Flash rom zip
    • Reboot
    • After inital setup, leave the rom to settle for a while




    • Me, for infinite hours spent with this project
    • Special thanks to @ananjaser1211, @SPARTANICUS and @Valera1978, and all those that have contributed to the 7870 development

    • Thanks to my best "pruh designer" @SaiFurR for the banner and being there in all my projects!

    • I don't need them, I don't need coffees or beers. I really hate see here people with high end devices asking for donations, but you can still donate money to charity. Donate money or simply help people that is really needed. If you like this rom you can make me very happy just pushing THANKS
