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?
As said above TB is mess now and should earlier go with other tool (I am using Swift Backup).
Try this
Copy TitaniumBackup folder on root of storage →
In Titanium → menu → preference → backup folder location → select Storage provider file system (click here) → selectDocumenProvide storage → it will open file explorer, set TitaniumBackup folder you keep on Int storage - and then select allow.

Hello dr Ketan,

i love your work and i use tweaks pro. i used the fullscreen gesture function. now I can't undo it anymore. Long press to deactivate and then restart unfortunately does not help.

Do you have any idea ? I didn't want to reset everything.

If you set from settings, it may not work correctly with third party launcher for example like Nova Launcher. (No idea if that have been fixed later)

Hello I hope someone can help. I have Ketan v4 with TweakPro. I keep Always On Display on all the time. However after a little while it keeps disabling and I need to manually enable it. Does anybody know why? Thank you!

I use use both, no issues. I use moderate volume boost & viper4android 2.7.1.6
Nice. Do you have any issues during loudspeaker calls, do people hear you without echo?

How much louder and better is the sound for music and etc?

I'm on the verge of amping up my sound but I'm concerned as I have had issues with loudspeaker calls on my last 2 phones, note 5 and S9+.

That's what I'm thinking but I can't figure out what! Either that or a tweak or csc setting. And no I didn't install good luck.
Troubleshooting time buddy... It seems you have to experiment and try to narrow it down.

Maybe try and install a working version of good lock which doesn't have limitations based on your region. In there you can find some pretty good AOD's, and at least in my case they always stick and never stop working.

I have a question. if i want to make a complete backup what i can restore at any time, which options do i have to choose with tw?
It's complex thing. Answer depends on why you want to restore and your current setup.
Routinely, we do needs boot,recovery,super,optics and data
Now suppose you have messed up something in system, restoring super is fine. In case you have something weird in data (usually happens while you playing with lot setting/third party user app etc and got messed up) - Here restoring data is fine.
In case you want to move on previous version of ROM, restore everything, boot,recovery,super,data,optics + Bootloader and modem of previous ROM. Here again a catch, sometimes, samsung blocks downgrading BL and Modem, in that case you can't move.
So, backup Boot,Recovery,Optics,super,Data and restore according your needs.

Ok, I'm pretty sure I'm in deep trouble. Since I was @ R5, I tried to dirty flash to R6.
Flashed super.img, R6 file, flashed CP, BL & AP. Nice reboot, reboot, reboot and reboot.... looped.
Can't enter TWRP, keeps running in bootloop... long time between the reboots.

MD5 checked: okay.

Can't switch off the phone, it keeps booting....

Somehow got into TWRP and now doing a clean install and following all the steps in the guide, clean install B (because the super.img file was still on it)... same issue. Reboot after reboot..... etc

And getting back to stock hangs in Odin too, keeps hanging at the <ID:0/004> super.img flash part....

Thanks for the help. I still can't suss it. I've checked through all ROM settings, and no luck. I can't install goodlock, it says unavailable in my region. I've never used it. And it seems to be quite a recent problem but can't figure out what's causing it at all. Every few hours, AOD disables itself, and I like it all the time, it's maddening. 😔😔

    Thank you guys!
    It's been just 24 hrs and nearly 100 downloads, no any bugs yet reported so glad to know users are happily using beta. Specially those users who are on non OXM csc and have no scope to test beta officially.

    Again thank you all for trust and love for this ROM.

    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.
