[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] azenyr:
This bug (Display not waking up) happens with ALL Oreo roms I've tested, even on my old Nexus 6P. It happens almost ALWAYS that I lock the phone normally and leave it on it's Ambient Display for more than, say like, 10 seconds. The more I let it sit alone there in idle/locked/sleep/whatever you wanna call it, the more time it takes to wake up. If it's there for more than like 5 min, for me, it will never wake up again, I have to forcibly reboot it. If I get a call, I can't answer it cause the screen won't turn on. If I unlock using the fingerprint, it even makes the unlocking vibration and sound (if this setting is on), so that leaves me guessing that the problem is actually the screen not being turned on and not the phone not waking up. But I'm just guessing here.

HOWEVER, if I turn OFF Always-on Ambient Display, this problem will NEVER happen again. From long ago (from the days dealing with Nexus 6P Oreo Roms) till this day, ALL Oreo Roms on both devices I have (6P and OP5T) have this unbearable bug when the Always-ON Ambient Display option is active. If you try to wake it, the Ambient Display turns off and the screen simply won't turn on again (depending on how much time it was with the Always-on Ambient Display active).

How to emulate the bug: Literally any Oreo ROM with Always-on Ambient Display, turn its option on, lock the phone, let it sit on the Always-on display for more than 10-20 seconds, then try to wake it up. Literally if you guys on AOSiP manage to solve this, you literally become the heroes of all Oreo roms, at least on these two phones. I love Always-on Display, but I can't use it.

One suggestion, I also haven't found a rom that forces apps to use the full 18:9 aspect ratio, a lot of them don't use it leaving black bars. Would be 10/10 to have this sorted out sometime.

I'm also gonna leave my ultra short review about this ROM:

- Literally the most stable and smoothest of all I tried till date. All roms on OP5T start to lag and "skipping frames" after a while. This one however, was the only one that actually kept itself super smooth all the time. I always use the stock variant of the opengapps, because I love the "Google Experience". Congrats to the devs, this rom is just beautiful.

However, like all roms I've tried on this phone, I always go back to stock after some days because of two simple reasons: stock always feels smoother (even tho I'm happy to say that this wasn't a reason on this rom, it just kept being smooth compared to others), and the biggest reason of all, for my use, is the camera. Not a single rom uses the dual camera (even if I go get the OP Camera apk), nor the image quality is decent enough. I take a lot of photos with my phone, specially on low light. I use custom roms to get new and exciting features not available on stock, but this leaves me with the feeling that I am losing important and useful functionality behind. I will always keep an eye on custom roms, and always keep trying new ones, specially new builds of AOSiP, the smoothness and stability it gave me, even with the full Google Experience that i love installed on top, and all my 100+ apps & social stuff, was respectable. Hugs to the devs for what they could manage to offer in this rom, keep going strong, make this phone & it's roms happily unforgettable ;)

And I hate the Nougat-Style of OxygenOS interface (and its dark quick settings), so the sooner I can get away from it, the better.
