Hi,
I have a Galaxy S4 GT-I9505 phone.
I installed official LineageOS 18.1 onto it last year and updated it to the latest version a couple days ago.
My problem is that I've never been able to make S-View functionality work since I flashed LineageOS.
(Before installing LineageOS last year, the phone was on its stock firmware, in which the flip case's S-View functionality worked as expected)
Specifically, the clock face does not show up in the rectangular area of the flip case upon closing its lid.
(I believe I set up this feature correctly in the Settings app)
On the other hand, the clock face does show up when I connect the phone to or disconnect it from the charger.
The clock face also shows up intermittently when the flip case is closed. I suspect it reacts to notifications but am not entirely sure.
There is also some other buggy behavior with regards to this: sometimes when I *open* the flip case (as opposed to when I close it) of the phone whose LED screen is turned off, the clock face turns up very shortly in the rectangular area of S-View, with the rest of the LED screen being black. Then the phone wakes up and the home screen is shown as usual. I can't reproduce this particular behavior at will.
I also have another Galaxy S4 whose model is SPH-L720 and I also flashed LineageOS 18.1 onto this one last year and the S-View functionality never worked either.
I filed a bug report via the official channel at some point (
https://gitlab.com/LineageOS/issues/android/-/issues/4307) but it got silently ignored.
Any help to solve this issue will be appreciated.
Thanks.
