[Samsung Galaxy S8 Guides, News, & Discussion] Salazar33:
I thought I'd leave some feedback after my use for few days.

Got an S8+ single sim G955F, unlocked bootloader, with TWRP and a custom rom (renovate Ice). What I did was installing stock firmware with Odin (CRL3), then wiped the data, installed the first update the phone booted to android Pie already, rebooted to recovery did another wipe, and installed the second update, just like instructed in the post. Phone successfully booted to one ui android Pie, no bootloop or anything.

- Been waiting for dark mode for ages, used to have substratum before but its not perfect and it doesn't cover up everything sadly (I don't use Samsung themes as I remove all samsung preinstalled crap), tho some notifications still showing in light theme for me, like Youtube for example.

- The battery is actually better, not by a big margin but I can notice the difference nonetheless!

- Love the gesture navigation, been using Fluid N.G with oreo and sometimes it crashes/bugs and having a built in gesture solution makes it easier and more fluent, tho! I wish samsung would let customize it even more, like give custom actions when you hold the gestures.

- Auto brightness doesn't function in my case at least, tested the light sensor and its working perfectly (*#0*#) so its not hardware malfunction.

- For some reason, it takes longer to boot! With oreo it was like 15s/20s faster not sure about what others might experience.

- RAM management seems to be better I guess, switching between loaded apps is noticeably quicker I'd say, not that much of a difference tho (Oreo was good enough already).

- Camera seems to launch slower, not sure is it the new app that is still in development or is accessing the camera itself got slower (I mean its still BETA).

- The mods I had in Magisk for the camera (Enables 4K60, 1440p120, better manual control.. etc), I am not sure if its incompatible with the new APP or its just not supported on Pie completely.

- Built in Dolby atmos without mods, like finally!

- Fingerprint still the same, thought it might get faster! but face recognition did so that's a thing (I don't use it).

- The fancy bottom menus style in one ui! total in love with, sure everyone will as well.

- Samsung keyboard can't be positioned the bottom, there is a slight space between it and the bottom of the display, it might be cause of the gestures, I use Gboard and it fixes that so didn't care much.

- GCam port from the Pixel 3 now works without crashing, in Oreo it used to work but it crashes sometimes, tho with a tripod and manual mode control I get better image quality at night than Google's nightsight. HDR+ still works like usual, along with portrait mode and other features.

- No idea why, but it seems I get a bit better 4G reception inside of my house now, thought Id mention it as well even tho I don't know if the Pie update got anything to do with that.

- The crap bixby is still there and no way to remap the button as usual.

That's all I can think of right now hope I didn't forget any, Ill be rooting if I find this BETA stable enough to be used daily, bixby will the first thing to go off (I use the button just like the slider in OP devices), then will try the previous mods that worked in oreo, might get lucky.
