Safe mode can fix if issue is related to user app, system app still remain same. So if happened with some system mod it can not fix in safemode
This kind of issue usually related to DPI or modules (magisk/exposed/lsposed) so worth to try that. Though safemode will auto disable magisk modules so first only disable module will be further helpful to narrow down issue. If that doesn't fix then better to try with safemode

open the camera app and go full in the settings on top of the display, this will hide any cutout or program modifying the statusbar.

Or use safe mode

First, completely power off the phone

Turn on the device and when the Samsung logo appears, press and hold the Volume down key.

if done correctly, "Safe mode" will display on the bottom left corner of the screen. If "Safe mode" does not appear, repeat the previous steps


if the problem not disappear maybe is something physical, looks like the screen is broken on the camera cutout from your posted pic.


Sorry for my english

Camera in full still shows it. Safe mode displays it. And its even in TWRP. There is no crack. If you mean the straight line from left to right, thats a slightly small screen protector.

No modules installed in lsposed. Magisk shows none and fox's has "Zygisk - LSPosed" and "Universal SafetyNet Fix" (by kdragon). I didn't install those so I assume they came with the rom.

I have installed Youtube vanced from ROM tool S21.
It works but its often very sluggish keep loading video endless time you need to click another video then go back to previous one then it might be playing.
Is any solution to that? I used to have youtube vacned on stock rom it worked smoothly.
[edit}
I had reinstalled it. Figured it out it only sluggish once i log into my yt account.

P.S Thanks to dr.ketan for hard work.

I have been downloading this now for 12 hours, is the server extra slow or? Waking up this morning, it's downloaded but now it's released. Sorry, I was not able to review before release. My internet was at 3mb down yesterday all day. I live in the mountains. Do I need to download a different version or is it all the same?

I'm having some difficulties to use some app which check safety. I've passed Safety Net Test.
My bank app detected my phone is rooted but I was allowed to install it and use.
1. I can't use Success Factors app for example. It says "Your device must meet security requirements"
Is any solution to that?
2. I love call recording feature but would be possible to record phones calls out of Whats App and Messenger?

1. Go to Magisk/Settings/Configure DenyList "tick" your "sensitive apps". 2. You may hide Magisk itself (look up for hide Magisk and follow the steps).

    Another excellent work!
    Everything flashed smoothly. Working fine @ the 1st attempt :).

    Just want to suggest, maybe in the next release, you can add something like this:
    Clean Boot Logo

    Those warnings screen that appear after unlocking the bootloader are very annoying,,,

    Thanks for your awesome work!

    Installation and Download & Notes


    Important :


    - This will void warranty.
    - As of now you will lose Samsung Pay and Samsung Pass forever if you root once, even unrooting won't help. (hope in future we can get it working on tripped knox device)
    - OTA won't work once you root device.
    - ROM Tool permission : Files & media - To save and read files, Calendar - Tool needs some time monitoring to avoid using RT immediately after reboot. Special access for accessibility service - Since Android 12 it requires for QS panel custom Toggl e.g. Reboot to recovery

    Installation :


    Read ChangeLog post for Installation instructions (link on post #3)

    PS : Who can handle consequences of dirty flashing, they never need to ask this question in forum. If you dirty install then handle it yourself .

    Guys
    Quite busy with life, just y'day started N10 re base so first needs to complete it. Later (when time permits) will start workings on beta2. Kindly keep patience. Thanks all.
    10
    Here some my thoughts and explanation about TWRP backup and restore

    Firstly brief explanation about what does partition contains.
    • Boot : It is Kernel
    • Recovery : It is Recovery
    • super : That contains odm,product,system and vendor partitoin all togather.
    • optics : CSC files (where we routinely making changes for csc features) and network settings depending on your carrier
    • prism : carrier related apps and other stuff . In odin when you flash CSC*_ or Home_CSC* these two optics and prism gets flashed.
    • data : That is all your installed app and made changes in settings

    Now what to backup/restore?
    • boot - Helps if something messed up with magisk or waht to restore kernel after flashing custom.
    • recovery - usually it doesn't require but if you flash some other recovery(TWRP) and you want to restore one in backup, that helps
    • super : As stated above these is main system, if something you have messed up in system/vendor (usually with flashing something, or erasing something) you can restore by super.img.
    • optics and prism : as explained above are CSC files, Rather than restoring it, I prefer to flash HOME_CSC*.tar.md5 to make csc compartment clean. So to backup or not not much important.
    • data : This very sensible part. I prefer to make data backup when there is no samsung a/c or Lockscreen protection there. Also don't restore it cross version of ROM. Also some common mistakes user making is, He/She clen install ROM and then restore data partiton of previous ROM. This is worst then even dirty installing ROM, never do it. It is just false sense of satisfaction that you made a clean install. According me, data partiton backup best to be made just after complete clean install ROM and setting up device without adding any account and lockscreen protection. So when you restore this backup, you will have a device just like you recently completed clean install and save your time to setup initial wizard
    Backup Application,Call logs,Contacts,SMS etc

    Titanium backup was ruling for decade for these but since A11 it's not trust worthy and on A12 almost useless.
    Swift Backup is now my choice (Some other like Migrate, App dash (by RD XDA dev flar2) also alternatives)
    For contacts : I do prefer google sync. Just adding google ac everything will be restore on it's own, provided you are saving contacts in google. In case you want to make off line backup of contact, there is a built in utility in phone. Contact - settings - export - This will create a file. Similarly browse same file while you want to import contacts. Catch in this is your contact image will not retain size and it just backup thumbnail picture.
    Only one utilility I have found that makes offline contact backup without distoring image quality is My Phone Explore client (needs on both PC and Phone). Also this utility is best for wireless file manager.

    Schheduled backup - A must needed utility.

    I always prefer clean installation (Factory reset withot wiping media files) and really it takes less than 30 minutes to setup everything.
    If you enable schedule backup utility in your Backup app (e.g Swift backup have this) and make some profile like
    1.Backup - new app at X time then it will auto backup all app that you have new installed at given time
    2.Backup updated app at x time - This will make backup of any app that you have updated in store will backup at given time
    3.Any app which get data changes frequently and you needs data changes like whatsapp then create a profile favorite app - add whatsapp in favorite and schedule it to make backup daily at given time.

    with these your device always remain ready to clean install anytime instead of last moment backup or some urgent clean install needed.

    Also Folder Sync is good utility if you needs duplicate copy of files from Internal storage with scheduled operation.

    Hope this may helpful and answer lots of queries for many.
