Can this be flashed in twrp? Does it have any performance enhancements over stock? These two things are what will make me flash this in a heartbeat.

If it had a kernel that was built with Clang 12, or Proton Clang 12, my goodness - that would be the icing on the cake. in my opinion, the stock kernel is just not that good.

Wow, that was fast! Currently running a OnePlus 8 Pro and this is why I'm switching back to Samsung. The OP devs haven't dropped anything new in several months. Awaiting my AT&T S21 Ultra 512. Fingers crossed on a root method for the Snapdragon! Cheers
Have you seen the Galaxy s20 or note 20 forums? It's like Dr Keton ROM and nothing else. If development's the reason you came to Galaxy S21 you're going to be very disappointed.

8 Pro development is/will going to blow this out of water. Just saying..

Doctor, I've missed yah. I'm so glad you planned on making ROMs for S21. I thought your work is exclusive only for the Note series.

Yes, this is exceptional. I do make rom for N20 series only. But some friends and loyal users insisted and couldn't resist.

Thank you doc, I will love my G998B more. I loved your ROM on my Note10+. I planned on buying the N20U but ended up getting S21, I regret a little because there were no Dr.Ketan ROM. But not any more. Thanks so much.

Bro there are so many users who bought note series(exynos) only because of you. Because your custom roms are awesome with zero bug. Now, you started making rom for S21 series, many people will head over to newer s series including me. Thank you so much for awesome work.

@dr.ketan , I noticed an annoying bug with the rom. Viper for Android simply will not install/process. It installs fine on stock one UI 3.1. Could you kindly take a look at this. Viper is hands down the best sound mod for Android that exists.

Can you tell me the exact steps you did to get this to work? What exact versions of viper?

Also I already followed your instructions on 'step two' for tweaks pro. I followed the instructions exactly and did not receive the Tweaks pro app that I paid for. Please send me the APK that I paid $25 for.

EDIT: Dr Keton came through and sent me the tweaks pro app. Very happy now.

Hello Doc, I'm about to install TWRP. I just have a few questions.
-Secure Folder is still a thing like on N10+, no?
-And the dual messenger is still bugged like the previous?
-Combo key required or no? Thank you.

    bmonteiro and Other test users​

    Kindly post your full review about SB1 as well about OneUI 4
    I have installed since two days but hardly opened any app other than settings, just spent two days to prepare ROM for users so any one can install it without going through pain of installing official beta. I have really no idea what is new in this beta. Code wise there are lot differences. Also samsung and google started behaving like apple and making tough for modification with every OS update. Let's see how further development goes!

    I'm on the ROM for about 3 hours now, no random reboots or anything of the sort.

    All my apps are working properly, made some calls successfully. Was not getting notification, but I noticed that now all apps that I open are asking for notification permission, so not a problem, just something to keep in mind.

    Some fame drops here and there, but I'm following the other thread where non-root users are also reporting this, so it's not related to this one being custom. Another thing for users wanting to trying out this one is that Safetynet will not pass, even for non-root users beta versions does not pass safetynet.

    Besides that, One UI 4.0 is almost identical to 3.1, some new features like battery protection, extra dim (which I really like)

    Can't say anything related to battery yet as it's too soon.
