I'll reply to myself.

My phone variant is SM-G998B/DS. It supports two SIM cards. I bought it in Spain.

I see Dr.Ketan's Tweaker Pro has CSC modding, this allows to enable the integrated call recording feature. I'll buy it as soon as possible if someone skilled enough or Dr.Ketan himself checks it's fully compatible with my phone variant.

I'm worried about my phone compatibility with your ROM on my S21 Ultra 5G Exynos2100 variant (SM-G998B/DS), as it's a Dual SIM one.

Has Dr.Ketan's ROM been tested in my phone variant (SM-G998B/DS)? Does dual SIM works? Any losing of functionality besides Samsung Pay and Samsung Pass and possibly Knox? I don't care of those, but I may care of the rest.
All of us here have the same phone as you. DS stands for DUAL SIM. All SM-G998B models are Dual Sim with the same DS tray like on your phone.

eSIM is on the american models of the phone with the SnapDragon processors. They have 1 physical sim and one internal non-removable one that can be used with some operators that support such a thing.

Your phone is fully compatible with this ROM. Do the reading on how to Unlock your bootloader, flash TWRP and etc so that you can understand what you are doing.
Even if you go trough all the comments in this thread only, you will learn a LOT. I personally made a whole post explaining how I went from STOCK to this ROM fully functioning, step by step.

Read up bro. Read up.

Thanks a lot! I wasn't aware of it, sorry.

So why there's eSIM and dual SIM menus in my phone? That's what confused me too.

Now I need to frind a way to check if BBVA España app can run on a rooted/magisk/whatever-similar device.

Okay. I'm slowly absorving information. I have busy dxays these days and was too ambitious, I'll need to be more patient. Sorry.


@dr.ketan

Any possibility to have automatic call recorder like in non-European stock ROMs? Those are the ones for Latin America, Indonesia (XID?), etc.

I want to buy Tweaker Pro ASAP, but need to wait until I get some incomes. Despite I got a high end phone, I have no money right now.

@dr.ketan you, sir, are a gem to this community! haven't tried rooting my s21u or using this rom yet though. rooted phones have much lower resale value where i'm from :(
Forget re-sale value bro. The market is broken and manufacturers have a big problem making new high end phones right now due to the issues in Taiwan and etc. For the moment your phone is TOP and it will stay like that probably until next year.

Do whatever you want to make your phone better and enjoy it, enjoy life as well.

Keep absorbing, it is a lot of info but worthy of knowing since it gives you freedom.

Your phone having both eSIM and Dual Sim menu option is some sort of mistake and likely just due to a regional bug in the software. Once you install the ROM and change the CSC (region) then the simcard options will likely just be DS.

If the S21 ultras in Indonesia are also the EXYNOS models like ours, then you should be able to install the XID region if it exists as a flashable region in the Ketan ROM. But if it doesn't, it is something the Dr. would have to include if he has the time.

Weird, XSG released second update within a wk. There might be a critical fix else it won't.
May be needs to release R06 based on UF2
It would make sense. There are some strange issues with the latest update.

I personally experience significantly poorer battery and also something seems wrong with the storage.

Sometimes when I take pics or videos they do not appear in the gallery properly but instead as corrupted files. Then if I reboot they re-appear. Also a similar story is occurring with screenshots, when I take a screenshot I cannot edit it and it appears corrupted in the gallery until I reboot.

The 1st time I realized that kinda issue was when most of the content in my Gallery had disappeared, I opened a file explorer and it could not find the folders and photos in the DCIM. Then it all came back after I rebooted.

These issues came up with the June update.

I'm having the same issues also. I have to give gallery storage permissions very often, or whenever I open it. Guess we'll have to wait for the next update for it to be fixed now

    S21ultra have probably too much padding on status bar
    Here above raw is stock below is modified, I think modified one is better and should replace by default?
