[LeEco Le 2 ROMs, Kernels, Recoveries, & Other Deve] ch@ts:
I installed this ROM about 15 hours ago, and here's my feedback on the the things I have noticed so far:

1) Camera - the stock camera app is pretty stable and feature rich, and didn't crash once I set it to record video in HD, and not 4k as was the default setting in my app.

Picture quality isn't as great as stock, or even as nice as Lineage 13.1, which is where I came from, but it's acceptable.

2) Dual SIM works fine. I don't have VOLTE, so can't comment on that. The 4G hot-spot worked for the short while I had it on. WI-FI has been stable.

3) I don't use GAPPS, so I need to use UnifiedNLP to get location without GPS, but that doesn't seem to work on Oreo. Hence, I can't get location indoors, but GPS works fine outdoors.

I haven't tried navigation yet. I'll post an update when I do.

4) Fast charging seems to work. It took about 90 minutes to fully charge the phone.

5) I haven't faced horrible idle battery drain. It's been draining at about 1% per hour, with either 4G or WIFI on all the time. It syncs files, contacts and calendar events to my home server, and I don't use any social networking apps, and that helps reduce battery drain a lot. I also use WaveUp - an app that wakes the phone every time I wave my hand over the proximity sensor, and that might reduce the battery a bit.

6) All the cores come online, and there are 2 big cores online all the time. My phone has a problem where it registers false touches if it gets too hot. On the stock LeEco ROM my phone was unusable. While I was on Lineage 13.1, the phone never got hot, and the false touch problem hadn't recurred in the last 6-8 months. I was doing a crossword puzzle on this ROM, and my phone began acting funny again. It's not a problem with the ROM, but my phone. Anyway, I installed kernel auditor, and reduced the minimum frequency of the big cores, and opted to keep only 1 core online all the time instead of 2, and that seems to have helped. I'll have to wait and see if the problem recurs.

7) I use profiles to keep my phone unlocked at home, and have it lock automatically once it disconnects from WIFI. I think that's a Lineage OS feature, and it doesn't seem to be present on ROMs based on AOSP. It's a feature that I love and use all the time, and I am really glad that it was implemented on this ROM. However, it has a bug, I think.

8) The bug. My hardware Home and Recents button stopped working 4-5 times, and I had to reboot to get them working again. I used the onscreen navigation bar, with the same result.

My phone is configured to remove the screen lock, and use a ringtone when it connects to my home WIFI, and re-lock the screen, and go into silent mode once WIFI's disconnected. But it seems that turning off the screen-lock completely causes the Home and Recents button to stop working. I changed the setting from removing the screen lock to replacing my pattern with a swipe, and the problem hasn't recurred in the last few hours.

9) I've rebooted my phone more than a dozen times since I installed this ROM, and it booted up quickly each time. Except once, when it got stuck at the Le Eco logo for a minute, and I had to long press the power button to turn it off. And then it didn't turn on again for a couple of minutes. But it did come back on, and everything's fine now. But it was odd for that to happen. I hadn't experienced that before.

10) The ROM has many nice features and customisations that aren't present in Lineage. Besides a (optional) new task switcher and launcher, it lets you assign custom shortcuts/actions to the navigation bar buttons. It shows the weather in the status bar, and it's got shortcut a to show you cpu info there too.

11) I haven't tested Bluetooth properly, but I did pair it with another phone, and sent some files over, and that worked. I'll try pairing it with my car this weekend, and see if I can make calls and stream music from it.

12) I really like that there's a switch that lets you change the SELinux settings from permissive to enforcing. I haven't tried an IR remote yet, but I think they should work with the permissive setting. I'll check and post an update later.

Those are my observations for now.

I really like this ROM, and am grateful that [MENTION=7985055]Rk585[/MENTION] has taken the time and effort to work on it.

Edit - tested Bluetooth calling in my car. Used it to call a customer help desk, and while there was no chance for me to speak, the call connected, and I could hear the IVR.
