Short review of this rom:
i flashed this rom three days ago (GAAPS nano)
battery life seems slightly better than stock rom
GPS works really reliable (drove 500km today with Google maps)
Rooted via magisk - Adaway/Systemizer/youtube as magisk module - no problem at all
Call quality is good but phone-speaker seems a bit too quiet - flashed Viper magisk module, speakers are loud enough now
performance is outstanding! this rom is so smooth! its like a new phone for me (after freeze/stutter bug from stock nougat rom)
fp sensor is working great
Fast charging is working but there is no indicator for it
over all this rom is great, far better than any stock rom and i did not encouter any bugs so far
My experience so far, I'm missing few features
I will update one by one
1. Cast is not working ( I have Samsung smart TV and it is not connecting)
2. No theme manager
3. No native video calling option in dialler
4. Camera quality is good but video recording is dark
5. Some time signal completely goes for few seconds then appears
6. No temporary disable option for navigate bar
7. Mobile download speed is low when compared to stock ROM download speed
Can someone confirm whether face unlock is working properly in this rom to unlock the screen

What about camera.... Is video recording working
My Review -
Pros - ROM is second to none, not even stock comes close in stability & battery performance.
Though i hope these issue will be resolved in upcoming builds later...
1- Sound starts playing from speaker even if you are plugged with ear phones during senarios.
2-Signal bars indicator keeps fluctuating often between 0-4(full strength) though data & calls works without breakage.
3-WiFi connections drops in between & connection works again automatically within 3-4 seconds.
4-Phones hangs little bit during Casting on Android TV.
5- Video recordings are little bit darker as of now.
*Tell you if found any.
This ROM is stable as much as stock ROM, I'm using this ROM as daily driver its better than stock with many features + latest security updates every week.

Ofcourse video recordings are a little darker as of now in any custom ROM, but video thing barely falls into my daily driver agenda, & those issues I've listed are bareable
Very nice to see and i am really happy that LOS is finaly official for this device.Great job from the devs!I am curious are there plans to switch from LOS 14.1 to LOS 15.1?
Experiencing random WiFi drops and inconsistent speeds, anyone else having issues with WiFi too?
Besides the WiFi issues the latest build is nearly flawless, was a bit of a hassle to get it running since I've never done this before but so far it's pretty good.
Thanks for the hard work

Can u list the bugs which u found while using this rom
Rock solid
Thanks devs !
Using this for some time now (January).
Everything works great and is smoother than the stock ROM.
The only minor bug is the fluctuating mobile connection display that has already been mentioned.
Had some odd torch-would-not-start issue after a long uptime (2 weeks), a reboot fixed that.
Battery rocks, usually 5-ish days, 7-8 hours SOT
Love Lineage OS - CM user since 2.3.x, wont buy a phone that has no chance of using LOS
Thank you for your hard work. In two days I noted only one problem: under battery usage Bluetooth is always on the first place with impossibile values (110%, 110000mAh) but it's not a real battery drain.
Superb ROM
First of all, Thanks for this great ROM, much better than stock or ridiciously fast compared to stock. Not even talked about stability.
Very smooth, fast. Long story short: VERY good ROM as daily driver.
I used this rom now almost a week and haven't had any noticable issue
1. Cast is not working.
I did not have this issue, i cast a lot but it is working better than stock
2. No theme manager.
not important to me but i can imagine that it would be important to other people
3. No native video calling option in dialler.
I don miss it, i normally use whatsapp for it, but it would be an welcome option
4. Camera quality is good but video recording is dark
For me it is better than stock, i don have any issues with this
5. Some time signal completely goes for few seconds then appears
I don have any issues with this, i use this phone for work al i call at least 4 hours a days (work only) i haven't had this issue once
7. Mobile download speed is low when compared to stock ROM download speed
For me i don have this issue, i think it is faster than stock but it is close
if i find any other things i will update this post.
But i want to mention i am happy that i flashed this ROM. It is a relieve that this great device as a great ROM which it deserves.
so thumbs up for all devs @mikeioannina, @highwaystar_ru, @FireLord

Not being able to post on the Development sections cramps on my style a bit, but I have a couple of questions:
* First of all, I am still on Oxygen, do you guys think there's any good reason to switch? I like Oxygen a lot and apart from a couple of issues (see below) I've been very happy with it... Will dzo ever show up again and merge the new drivers into his release?
* Have the camera and GPU driver from the official 2.3 been ported to any other ROM?
* I've been seeing a lot of ICS related ROMS in Development as of late, is there a fully functional ICS ROM yet? What's stopping us, since it seems almost every other device is making some progress with it (i.e: having hardware acceleration enabled, radios working, etc.)?
Problems with Oxygen:
* Light Sensor behaves strangely: for example, with auto brightness enabled, turning on or off the light in my room makes no change in screen brightness. If I put the device close or directly under a lightbulb it will only then begin to change. I can confirm this with some sensor testing apps. Is there any way to calibrate the light sensor?
* Microphone acts strange: I have never seen anyone report this, but when I connect headphones, then try to use for example voice dialing or voice commands it will not work (wait forever) or simply give an error. If I disconnect the headphones after I tried to use voice it will never work again unless I reboot. If I connect headphones, never use voice, and then disconnect them and use voice it will work as it should
* Signal Strength very irregular: I live in a area with difficult reception, but signal strength is insane, sometimes is goes from 0 to full bars like no big deal
* Camera's FPS very jumpy (new drivers will fix this?)
* No access to internal storage: I knew this going in, but still...
* Flash videos sometimes green and overlapping the screen. This happens with both the YouTube app and any video player that can play FLV. It only happens from time to time and I can't reproduce it.
I went straight from stock (TMN Portugal) to Oxygen, never messed around with any other ROM (I tried CM7 for half an hour or so) but these little things start to bother me, plus it breaks my heart to know that the camera and GPU could be much smoother just by using different drivers. It also scares me that Huawei disabled the standard method of installing Recovery and rooting, so I'd prefer not to upgrade to the official ROM right away. So, is it worth to change ROM at this point? Can you help me with any of my problems with Oxygen?
Hi!
I tryed "all" ROMs I found here in XDA, Oxygen for me is not enough, it just lacks of "options" I love the Cyanogen Settings, you can do a lot of customizations there. Im on custom ROMs for 5 months now, never had a problem with the phone itself. Strange rebooting, camera stopped working and drainage of the battery does NOT count in here. I would suggest you try CM for more than a half hour since - in my opinion - it is the best. I hate the original Froyo, because it lacks of customization. So MIUI is not an option for me, it is just to simple. I was thinking I know all about flashing, but yesterday I just bricked my u8800, simply because I did not notice the + on the end of the official 2.3 update and installed update for u8800+.
My suggestion is, to follow guides here on XDA (they are excellent) and try all the ROMs, and see which one suits you best.
I'm also very happy with Oxygen, I'm still on r1 and have no major issues at all, so thank you very much dzo!
But I hope for the future that dzo will continue to update this rom so we can get better drivers for camera and other small fixes. It looks like the official rom will never be an stable option for us...

So i finally gave cm 12.1 a chance because it's been rolling for a while now... and i was actually pretty impressed. The one issue i couldn't deal with is the bluetooth audio playback in my car. Basically it was playing too fast, then pausing every 10-20 seconds and then continuing to play too fast again (also at a slightly higher pitch). I was able to temporarily fix the problem by turning bluetooth off and on but it came back. other than this i didn't see many issues and thought it was pretty good, but for no i'm going to go back to stock until this issue is fixed, i did find that it was already reported to the cyanogenmod team and they are already working on a fix so i'm waiting impatiently until it's fixed and i'll probably be moving from stock kitkat as my main rom to cm 12.1. How has everyone elses experience been with cm 12.1 nightlies so far?
What doesn't work. (if i missed something here post so i can update)
- saving 4k video (1080p works tho)
Battery life ?
- used to be terrible but it's almost as good as stock now but with better performance.
hey
i would like to use CM as i was doing that on my Moto G. the questions I have to users of the newest CM version:
- does quickcircle, google text-to-speech, intelligent screen (LG app) features work?
- what is the quality of videos and pictures taken by the phone running CM opposite to android v20i?
thank you.

1. Quickcircle won't work. To make it work again you have to install a special app. Google text-to-speech works ok for me (I haven't test it too much). LG features/apps won't work
2.For me the quality of pics and videos are the worst I have ever seen!!!! (Much better in the stock LG)
My experience with CM12.1 was average. I was waiting for something better. Camera is awful in the Custom roms. Battery life wasn't the best. In terms of performance the cm12.1 is better than the stock lg.
i've only been running cm 12.1 for a few days now so i don't have alot of substantive input, i did find a fix for the bad bluetooth car audio using a macro/tasker app but i think they have fixed it in the nightly released today, i'm downloading it now it says bluetooth stream parameters in the patch notes so i wont bother sharing my fix until i try this nightly to see if they already fixed it. i'll give a better review of whats working and the camera/video quality after i have a chance to play around with it more.
by the way anything running ART instead of DALVIK cache/runtime is going to perform better but it's at the price of xposed modules and such, i'm not expert on it but i know they switched to ART cache/runtime to be more competitive with the iphone. On Kitkat and lower an android device needs better hardware to output the same performance as an iphone with lesser hardware. ART should fix that problem. If you are curious google ART vs DALVIK
*edit* yeah bluetooth is fixed with the newest nightly update... atleast for my car which is a mazda 3. (yay)
Avrage camera and bugs like video not saving after recording is main culpit to not use CM 12.1. Otherwise it is good as clean android can be.

Videos do save. It is a issue with 4K video ONLY. Switch to 1080p video and videos save just fine.

I found that myselfe, tnx. But I believe that issue is fixed already. Maybe Im wrong, but I did see in changelog or other forum. Maybe someone can test it?
I switched to stock kitkat, I love CM, been running CM since it was 10.1, the problem is that it starts really really fast and after a while CM 12.1 becomes laggy it drives me crazy, other than that is the camera quality which doesn't bothers me as the performance issue,
I guess we'll need to wait for LG to release the G3 source file but who know's when that's gonna happend
good news the latest daily added some balancing between power and battery life. I went from losing a huge chunk of my battery during work when my phone is in my pocket to going 9.5 hours at work and coming home with 94% battery. (that is alot of standby but i use my phone at lunch and have bluetooth running for about 50 minutes of driving). Basically it got alot better, i'm not sure what they did but i did notice that there is a balanced setting in battery screen that i didn't notice before. Anyways I think those who were concerned about battery drain my have had their wishes answered over the last few nightlies.

Phone encryption not working?
I've just flashed the 20150603 CM12.1 and I cannot seem to get the phone encrypted. On the reboot to start the encryption, the phone gets stuck in the CM boot animation and the encryption process never starts. Any ideas or suggestions? Many thanks in advance.
I'm on 06/05 nigthly. When I plug the phone in my computer, it's not being recognized. If I change from MTP to PTP, then it works.
I've tried going to Device Manager, and could see that my phone is being recognized as a Nexus device. I tried installing latest drivers from Google's website, but I got a message saying that I'm already on the latest version. So that didn't do anything. I've tried uninstalling that "nexus" driver and rebooting my PC, but it somehow came back when I plugged my phone in. Trying to update gave me the same message.
If I run "adb devices", I can see that there's no devices (it's enabled in developer settings). If I enable ADB over WiFi and try to connect -- it works, and I can do whatever I want. But only over WiFi and not via USB.
Tried different cable and different port as well.
Hello, I'm searching a rom based on android 7.x, i've tried rr 5.8.3 but i had the fp problem and battery drain, all other roms 7 have fp problem. I want a good rom with no battery drain and fp working. if there isn't one ,link me a good rom 6.0
On next day should be released miui 9 dev for our device. Keep an eye on this thread https://xiaomi.eu/community/forums/miui-weekly-rom-releases.103/
Any update?
I can't say for sure about FP since all the recent Nougat roms have worked fine for me regarding FP.
I would recommend LOS from 28/8 for the battery alone. It's pretty close to MIUI:

My initial tests with LOS 28/8 were great, but there is a bug with the stock camera app. When recording video at night the recording is very dark and has some artifacts. I was able to get around this using Bacon Camera (Open Camera and Footej Camera also work). Other than that I haven't noticed any bug except for compass being out of whack, but I'm sure it'll be fixed soon.
No reason to be scared though, if you backup in TWRP you can always roll back.

Both fixes are bootimages, so they cannot be installed together. I guess the later fix (brightness) already contains the charging notification fix.
I think I have a good Lineage build based on other guys' sources. I'm testing it for a couple of weeks - no reboots, all the bugs seem to be fixed, battery lasts for about 2 days for me. Drop me a message if interested - if there will be a decent demand, I'll publish my build... and may be ResurrectionRemix.
I really still enjoy using this table and LineageOS 14.1 breathed new life into it from the stock Andriod ROM of KitKat. If not does anyone suggest anything other than LineageOS to run on my tablet that would perform any better than LineageOS.
Thanks,
Lime
Hmm nobody has any thoughts?
Resurrection Remix is a very good and stable ROM. But you leave curious...
What is lacking in Lineage that leaves you wanting?

LOS14 Issues
I have 3 issues with LOS14 on my SM-T520 wifi which I didn't have with a former CM Rom:
- I like to hold my Tab in different orientations and android rotates the screen likewhise. But the unlock-screen is not rotated and allways shows same orientation no matter how i hold the tab.
- I play some games on my tab with ad videos. In some games those videos are played in full volume for a fraction of a second even though my volume is low or off. This makes an irritating noise whenever one of the video starts.
- In some games android seems to overload the cpu regularly for some milliseconds and the game hangs (graphic and sound) but only when the tab had been running for a longer time. When I then restart the tab everything works fine.
I had a CM on my tab before and I didn`t have any of these issues there. But CM is no longer supported or updated so I switched to LOS14. Appart from these issues LOS14 runs very good on the SM-T520. But like limeman35 said there seem no progress in developement. At least there are nightly builds from time to time with service releases from android.
I am a newbie when it comes to rooting. I've never tried it but I have a Samsung t525 an I check all the time for system updates for this tablet but there never have one. I've even called into Samson an they told me you cant download any updates at all. That is hard for me to ac Sept. There has to be something I can to to utilise my tablet. Will you please explain how to root my tablet? Ty Pawneehappygamer
Hello,
as the object I would like an advice on the choice ROM for my G900F, no matter what version Andoid is, the important thing is that it is fluid, stable, light and low battery consumption.
Currently I have the latest stock firmware with root and TWRP.
I saw this ROM, what do you think? https://forum.xda-developers.com/showthread.php?t=2741302

You may want to try out AEX Pie, currently have it installed on my G900F, battery life is fine. Everything's working apart from the occasional WiFi (just unlock screen for it to turn back on automatically) or Bluetooth cutout (which is fixed by turning BT on and off). Barely happens, I'd give it a go if I were you.
Otherwise LOS 16.0 would be a good choice as well.
Camera's working 100% on both ROMs though I'd recommend the A2 camera (thread here on XDA) as it is nicer to use and the quality is slightly better.
