No, not until synergy and substratum are updated by the OP. Evidently they don't want OneUi 3.0 or 3.1 because I'm pretty sure anyone that wants has the ability to get it. I lost a lot of substratum themes from the play store because the dev's didn't want to update their phones and looks like that's what is happening here too.
I feel the same way, the dev has left us in the dark. It would be nice if he would respond and let us know what's going on.It's a shame that nobody has yet to figure out how to get this to work for unrooted devices running Android 11 and up. Maybe the limitation Google implemented with the hardware overlays being restricted might interfere but it's just a damn shame there's no universal theming method like this or at least I didn't experience anything like this since the last time I used it with Android oreo.
I personally prefer hex+. Unlike substrate him that one is permanent less of a hassle when it comes to compiling the themes and it's much more foolproof and doesn't risk anything for your device. Unfortunately that's only Samsung based so out of luck for non Samsung users.
Sometimes I wish there was a truly foolproof method to rooting devices specifically my Sony Xperia 5 Mark 2 but even then there are limitations while the method may be foolproof nine times out of 10 they're reliant on PCS as opposed to helping Mac users, I don't know I felt like ranting. Rant over LOL just needed to get that off my chest, regardless of my not being able to access this I am glad that it exists and hopefully it acts as a stepping stone for further development to eventually get a rootless option at some point maybe with the new Android 12 update who knows
That is odd. Try uninstalling synergy from your phone, reboot and try again. If that doesn't work then the only thing I can think of is that Google hasn't let it out fully.
Yes, it should but the process has changed.
