Does applying the Essential Fix "need" to reset all my QS tile locations? (I'm on N976B) I don't use the built in adblocker and have my own tile setup. It's slightly cumbersome to keep re-setting this up after every Rom update. That being said, the ROM overall has been amazing. Keep up the great work!
[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] dr.ketan:
Yes, because many users still flashing dirty and that may mess up it if it doesn't reset.

Also if you clean install, you needs to rearrange it, so I believe it's not too hard when you skipping clean install. Sorry it will remain same.
[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] gabesztdi01:
It's all right, but one thing's not, after a call, when I hang up, sometimes the phone restarts, what makes that happen?
[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] dr.ketan:
None have reported before, but likely not rom. Possibly magisk/xposed module can cause this kind of issue

Clean install again, don't install anything and watch if it happens or not

If still issue, provide log.

Hi Doc, thanks for the update. Is it possible for you to check the app BDO Digital Banking as this is the only app i'm having trouble using (it's detecting root) i did all the necessary steps to hide root but it still detecting it for some reason. It worked on a different rom, but i'd prefer to use your rom. hope you can help me on this one
[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] dr.ketan:
I have no reason to believe it's a rom issue. It's all about magisk, your existing setup.

I have nothing to offer, you can switch rom if you find it working on other rom.
[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] vu tien hai:
Hi, this rom can use dual sim on note 10+ 5g korea Sm-n976n?

And root is default in this rom? I dont want root

Thanks
[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] j3yps:
If you find some free time, pls do check it out. as weird as it may seem, that app will only detect root on Ketan Rom, I don't know if you remember me but we tried working on the Note 8 OEM Unlock fiasco before haha, anyways will try and check back once the rom gets updated again. thanks
[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] dr.ketan:
Nothing really.

Most of the time craps could be your installed app like titanium, root explorer etc. or some folder like Titanium/TWRP etc

I haven't heard anything rom level fix for root detection.

@dr.ketan hi doctor....

good day to you....

so with the change of bootloader number, what's the way to flash android 11 stock and your rom now to keep the option of rolling back if i want to?

if it's too complicated, i love this rom so much, i am prepared to stay on bootloader 7

thank you
[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] dr.ketan:
If you are already on bootloader 6, simply flash rom and don't flash bootloader

Though I recommend latest bootloader, as there is nothing I found required to roll back
[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] gabesztdi01:
who installs in what way? i have a usb converter and flash drive but i noticed that constantly if i plug it back into the computer it asks for a repair, the file system gets damaged after i unplug it from the phone? therefore, it may even be a faulty installation, I suffer from this
[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] pvillasuso:
Don't use the usb converter , that is the problem !

I have tried 10 times to lock unlock and no issue. Rom doesn't have this feature but i you have installed such mods, previous rom with this feature can cause it too

If you are a TweaksPro users, I recommend to flash stock CSC (HOME_CSC*.tar.md5 from your region. Then from TweaksPro - csc features enable applock

How can i get it on your rom
[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] TheFerhatKing:
I use this ROM since I rooted this phone and always flash my DBT CSC home after you push a ROM update.

No heavy mods installed, only Viper, GPay SQLite fix and some other Emojis, Busybox and Advanced Charging Controller that's it.

It happened to me even after clean flash after some while. It does take some time bevor it starts to randomly fc.
[Samsung Galaxy Note 10+ ROMs, Kernels, Recoveries,] dr.ketan:
May be some modules can cause, anyway log will be helpful. For other user, flashing CSC have fixed issue as said above.

I'm using stock DPI but maybe smallest Zoom setting in display settings interrupts but this is a normal setting from One UI and no mod or something else.

It happens on every app that I lock.

I edited my csc xml and added applock line inside I don't know where I got it from I forgot.

I provided my xml.

Easiest Test :

Make backup of existing data

Flash Q Bootloader and modem on R07 with Odin, If odin allow it (remember, you are checking just Q BL passing or not, even if passing device won't boot before you go to next step) to flash then, again reboot to download mode and flash full Q stock firmware - reboot to stock recovery - Format data - Done.

In case Odin fail to flash Q bootloader, simply flash R bootloader (from ROM download area) and you won't lose anything on R07
