Galaxy A52s: Updating from OneUI 5.x to 6.1 resulted in notifications not lighting up lockscreen anymore... please help

[YY99]

Hello,

I have recently upgraded my Galaxy A52s phone from OneUI 5 to both 6.0 and now 6.1 (I postponed this update for a long time because everything worked so smoothly and I did not want to ruin the functionality of the phone). Turns out, it is ruined (hopefully you can convince me otherwise).

On OneUI 5, if my screen was off and someone sent me an e-mail or whatsapp message, the lockscreen would light up (in combination with vibration and/or sound, depending on my settings).

But, both with OneUI 6.0 and 6.1, my lockscreen just refuses to light up when a notification is present. I know a notification is present, because the sound and/or vibration still works when someone sends me an e-mail/whatsapp/etc., but the lockscreen just refuses to light up. I have already looked at the settings; please see the attached pictures to see which settings I have turned on/off: https://imgur.com/a/j7058Dh

It does not matter if 'Always On Display' is turned on/off, the issue still persists. I have tried to restart and power down/up the phone countless times, not once has it worked since updated to OneUI 6.x.

I do not want to rely on third party apps, my A52s had this functionality that worked PERFECTLY during OneUI 5.x and I just cannot accept relying on third party apps for something that a) worked previously and b) should be functioning because there are literally settings you can use to achieve it.

My phone is up to date with software updates. I am not using a custom ROM, it is not rooted.

If someone could please help me fix this without third party apps, that would be so so so appreciated!

Unfortunately, I have tried everything you are saying, but nothing changes. The only thing I did not try yet was the AOD for new notifications, but that is only a half-fix; now the AOD is on when a new notification is there, but I am looking for the entire screen to light up fully, instead of showing the screen at 99% darkness because of the nature of AOD. I will make a bug report, thanks again for the suggestions.
