Hello everyone
I have received Android 12 on my “Note 20 Ultra 4G”
And I wanted to start converting my Android 11 themes to Android 12
But for some reason when I apply “preview APK” it doesn’t change the notification panel colors and also doesn’t change the PIN on lock screen
Even I made a new theme for test and didn’t work!
Am I missing something? Anyone know a solution?
And want to mention that the Android 11 themes still working on Android 12 and show the colors
That’s right! Also, the clock and date settings on the lockscreen are not applied. The problem only applies to “S” from the last GTS. I sent an email to support on Friday and I’m waiting for a response.
It is very strange that such lazy amateurs still work in this company. We do not have a stable version of the GTS, and it’s already mid-February.
Yep. Also sent in a ticket about this on the 10th. Notification Panel and Quick Settings not theming.
I sent also a eMail and opend a Ticket. Still waiting for response. As @Alex_Pie said its really difficult to make a Stable GTS Version (ironie)
The funniest think, 2 Themes approved today and they have this Issue
Today a new version of the GTS was released, these problems were fixed. With the rest of the errors …, we are waiting for the firmware and application updates. 
Oh wow! Its been released like 3 months ago and still have this major problems?!
Good thing its been fixed now… lets wait and see
Thank you everyone for the response and all the information. I appreciate it
They rejected every one of my themes exported with v12.0.30w.1 due to the notification screen visibility issue…
At least they didn’t suspend my themes 
It’s also interesting that they don’t test a new tool before release. I’ve never heard of such a thing, it is just shocking. The notification screen visibility issue was something that would have been caught with the most basic of test plans 
Another thing is interesting, they will fire an employee who made such a gross mistake or simply punish him. 
There has never been a Issue like this since 2016 and it was fatal.
21 more rejections this morning… all from the GTS version that was supposed to be good!
And because Samsung keeps 30% of sales, we are actually paying for this support, and eating the cost of all the rework
