My ROM doesn't touch any CSC, so it will remain same if you already have activated through changing CSC.
Also My ROM have built in manual call record option available by default which is working on any CSC. Tool having extra benefit (along with other plenty of options) is you can use it on stock ROM with any CSC.

That's nice to know. But from my experience trying 15+ call record apps, all have issues. I'll show a few of them, the most common ones:
- They record calls using the microphone. If you mute your own microphone, the other part of the call not gets recorded.
- If you are in a call and a new call gets accepted, both calls get merged in the audio.
- Issues putting the number of the call. Sometimes random contact, others a random number.
- Some calls not get recorded.
- Low quality audio, inaudible or low volume.

I don't know what call recorded you put. Maybe because using Magisk and such, it uses root features that make these issues gone.

Thanks a lot for your reply!

PS: I'll try this weekend to install your ROM. TWRP works, but the previous installed ROM (stock from Indonesia) doesn't). I'll research about it.

Are any of you guys using the XDA version of the ROM and with the Wakelock fix enabled noticing that after some time the wakelock starts going hayware by itself?

If it showing 61 wakelock in 21 hrs then it is normal. As explained in previous page still wakelock will happen while screen is on on XDA version, but that doesn't make much drainage as device is alrteady awake.
Once try disabling fix and keep device in pocket and walk for few minutes, it will show difference.
Also I suggest you to use BBS instead of Gsam app and look into Partial wakelocks, which will show better stats and battery drain with wakelocks

Right? They just can't understand... So many people from so many countries and different languages and most ask for help and supply with supportive stuff in their own language. Like we are all obliged to speak everyone's languages..

That's one of the reasons all MY devices are in English, preferably American one (I prefer words such as "favorite" instead "favourite", for example).

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.
Just looking to clarify. I haven't rooted yet but my 998B/DS has both dual SIM and eSIM. When I switch to eSIM, which I did when I went to the US last month and used an Ubigi eSIM, it switched off the second SIM and when I got back and turned on the second SIM, it switched off the eSIM. TLDR: I can choose dual SIM or primary SIM plus eSIM. That's not something I am willing to give up if you are saying installing Dr Ketan's ROM will take this away.

Well that is indeed peculiar. If you went to the US and the esim function worked, then it is not a bug as i initially thought. The strange thing is that we have the same model phone but I don't have the esim option. However, my CSC is EUR. And yours must be different. Installing the KETAN rom does not change the CSC so logically the esim option would remain there. But @dr.ketan should confirm just in case.

I imported mine from Amazon Germany. My service provider software version is
SAOMC_SM-998B_OXM_DBT_RR_0010
DBT/DBT.DBT/EUX/DBT

I just assumed mine was the same as all other 998B from Europe. Makes it even more difficult when sourcing a phone if you cannot be sure what you are getting.

I was really pleased I could use an eSIM in the US as I did not have to try and find a local SIM and when I am home I normally use two local SIMs.

EDIT: By the way, Samsung Germany has a good record of replying to questions about specification of new phones asked on Amazon.de. They even answered a couple of mine before I bought it.

@dr.ketan Hi Doc! How can i disable fullscreen gesture? Long press to disable isn't working in tweaks pro.

Edit: All good now.
I also just turned it on and wanted it off immediately but long press and reboot doesn't work.

Go to the settings of the phone, then disable and re-enable the nav bar and press whatever you see and it will re-appear.

Edit: I noticed you figured it out but I don't know how to delete my post now :D

I have 2 question regarding the ROM tool PRO.

1. has anyone tried the battery protector option that charges it to 85% max and is it safe?

2. Has anyone tried turning on the volume boost options and what is the difference? Any issues?

I am not sure if this is the right place to ask, but since I am using dr ketans roms for a long time and never encountered this, I will try. I am trying to do a backup via TitaniumBackup and I simply can't copy the folder with files. Seems permission related, I tried some suggestions like chmod 755 via twrp, but it doesn't do the trick. If I copy something into the folder, I can copy those files out, but the files that are made my TitaniumBackup on the device, I can't. It just says "something went wrong"

It is possible that Titanium Backup is too old for Android 11. The last update of this app was at the end of '19. I also had problems with restoring apps and app datas. There is a better and newer app to make backups. Its called Swift Backup.
I don't know, it seems to still be a de facto standard. @dr.ketan since tb is included, can the folder be unlocked by default in some newer version of rom, or maybe via Pro Tools for subscribers?

    It's 5 min job to create twrp flashable zip for bootloader and modem, but it always carry high risk of bricking device. If bootloader file is corrupted, and suppose you flash using twrp, your device will hard brick and only way is to replace mobo
    That's the reason, I never provide twrp flashable bootloader. My bootloader files always comes in md5, so in case you have corrupt Download, odin will failed to flash to protect your device.
    So, in sort never expect twrp flashable bootloader by me.

    How?
    Doesn't work for me. I'm on latest R07, using LSposed Magisk module and that seems to have broken the SafetyNet.
    I have tested LSposed yday for other purpose and safetynet passing with it too. Also GooglePay working fine here too.
    Regarding your old query about, dual message screen bootloop is newly implemented security since A11. As of now only Pro version have experimental fix.
