[Galaxy S 5 Android Development (Snapdragon)] Oswald Boelcke:
@cvxda: Corinna, I really appreciate your work. Thanks very much for this ROM. Definitely an excellent job well done.:good: Do you prefer donations via PayPal or rather by other means to save some fees? I definitely like to support your work and to offer some cup of coffee or tea.

Running RR-O-v6.1.0-20180711-kccat6-Unofficial now for two days together with Magisk v17.7 Beta and some modules as shown in the screenshot (SS), Xposed framework and a few modules (refer to SS) and my accustomed app portfolio. This means especially GApps-free but with microG, no Whatsapp, Instragram, Facebook and all other things belonging to this "family". Using Conversations, Silence, R2Mail2, OpenCamera, OSMAnd+, OpenVPN for Android (connecting to the RaspberryPi at our router), AFWall+, Adaway, MyAndroidTools Pro, SD Maid pro, AppOpsXposed, Greenify, XPrivacyLua in order to just name a few. TWRP is currently version 3.2.2-0 but I just download twrp-3.2.3-0-kccat6.img to give it a try later.

The ROM itself runs seamlessly, no unintended reboots, baseband/modem available/known, no lagging, very fast downloads. Positioning is working via both, network and GPS (amazing fast GPS fixes). Bluetooth working. Theming working. Didn't test the ROM inherent camera, SMS, email, browser applications, or MMS.

So far I haven't recognised any issues with RR-O-v6.1.0-20180711.

The only thing I'm not really happy with seems to be the ROM inherent kernel. I observe a pretty high (from my perspective) battery drainage that I believe comes from very extensive Awake (Screen Off) times, which might be triggered by kernel wakelocks. Just tweak the kernel settings a bit with Kernel Adiutor (though not too much to tweak with this kernel) and continue to observe. Probably, I'll post a respective BBS idle dump in near future. I also realised - and connect this also to the kernel, while charging with my HAMA charger on 2A the CPU gets pretty hot but when using the charger on 1A the charging time is really extensive. It's really a pity that not very much custom kernel (actually, I only found one and none for Oreo) are available for the G901F. I wish somebody had ported and would port the G900 Boeffla kernel to the G901F. That kernel is the very best of its kind. If I occasionally find sufficient time I probably consider to teach myself how to build kernel... We'll see. And Corinna, please don't get me wrong; I'm not complaining about your ROM and your work, both are simply superb. Just from my other devices in the past and they aren't gone yet, I experienced how much is achievable by a Boeffla kernel.

Last but not least - in order to be honest: I haven't discovered any advantage by Oreo yet; I'll give it a chance but really don't know if Oreo becomes my daily driver on the G901F. Definitely, I'm devoted to RR and its rich features for customisation but there's an extremely high chance that I'm going to (I call it) upgrade to your RR-N-v5.8.5!

UPDATE (2018-08-10): As indicated above I slightly changed the kernel's settings e.g. I'm now using "conservative" as governor. All my other tools also now enjoy their final settings. Last night I took a BBS idle dump (file attached) over eight 1/2 hours, and taking into consideration that e.g. neither my messenger client nor my email client are battery optimised or greenified I'm definitely extremely happy with a drainage of only 0.7%/h and an Awake (Screen Off) time of 25 minutes. I really don't recognise any strange kernel wakelock (I'd anyway unable to defeat this unless changing the kernel) or unusual system behaviour. Just for completeness two things to mention: Two days ago I got a new original genuine Samsung battery built in July 2018; WiFi is not running on DHCP but with static IP (and with the RaspberryPi in our home network as DNS server). In order to be able to assess and relate the above mentioned drainage, I'm going to get an idle dump in Airplane mode as soon as it's possible. To get another reference, I plan to also check how much the battery drains when the device is off.

TL;DR: @cvxda - RR-O-v6.0.1 starts to convince me but I still need to figure out Oreo's advantages.

UPDATE #2 (2018-08-10): It seems that I don't receive notifications by the email client when messages arrive, or the IMAP IDLE pushes don't work while in doze mode. However, cannot relate this issue to the ROM (yet?). Need to further observe and test.

UPDATE #3 (2018-08-11): First regarding the observation mentioned above at update #2; aural notification happens but not notification LED.

Anyhow, I'm now convinced that Oreo doesn't provide any advantages for me personally, and I decided definitely not to use it anymore in future. Yesterday, I migrated to RR-N-v5.8.5-20180413-kccat6-Unofficial and commenced the setup of my system to my desire. Very happily I immediately realised that I'm e.g. able to toggle SELinux to moderate/permissive on RR-N. Currently assuming that RR-N won't have any issues I'm only reporting back in this thread if I experience a problem.
