Hey guys,

I have a question. First time I have flashed a ROM. the original ROM was pretty ****ty so installed LineageOS using TWRP.

All is fine and performance is great, no bugs. I'm just wondering when I go to settings --> LineageOS updates it shows 1 update dating 8 September. I downloaded it, phone rebooted into TWRP, installed with no errors, rebooted. Now the same update is still showing. Does this mean the installation failed? LineageOS-version shows 09-08 though in the settings. So i'm kinda confused by this if this is normal behavior, or the installation fails.

Heyyo, sorry Pascal but the LeEco Le Max 2 doesn't natively support QI wireless charging.

You would need something like this receiving pad for QI wireless charging. I'd just sandwich it between your phone and a case

Dear AppiePils, hrox,

May I know which camera apps you are using that work on this rom?

None of the camera apps that I have tried (including the default org.cyanogenmod.snap, leeco's com.android.camera2, google's com.google.android.GoogleCamera) are able to take proper pictures. E.g. pictures are exposed as though there is no flash (even though the flash fires), pictures are unfocused or focused on the wrong point, etc.

Volte calling is not working on lineage os build 22-9-17. Was working in build 8-9-17 Not sure about normal calling.

Also, enhanced 4G LTE mode is enabled in Mobile network settings. Mobile data is working fine. When I try calling through volte, it displays call ended instantly after placing the call.

Thanks

Here is a logcat started just before trying to initiate the call and ended just after call is automatically ended:

[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] ThE_MarD:
Heyyo, sorry to say but flash is currently known to have issues on Nougat ROMs. The issue is LeEco did not (and probably never will) release the source for how the MSM I2C flash works on the Le Max 2 (and I believe the Le Pro 3 also has the same flash) so sadly it's one of those major issues much like the camera zoom as well.

Actually XDA put up a good read about camera shims a day ago if you're interested to see why it's so darn hard for them to create shims

https://www.xda-developers.com/came...opers-make-hardware-work-without-source-code/

Heyyo, which dialer are you using? The stock LOS/AOSP one or the Google Play store dialer? A different one?

For CDLA and OTG, can you please confirm which earlier build it worked on?

From what I've seen with commits to the LineageOS 14.1 LeEco msm8996 kernel which the Le Max 2 uses there haven't been any changes that should affect CDLA and OTG since July 23, 2017.

https://github.com/LineageOS/android_kernel_leeco_msm8996/commits/cm-14.1

Has any build since July 23, 2017 had working CDLA and OTG? If so can you please confirm which ones?

I started using lineage only since 2017/09/08 build, so I don't know about the earlier versions.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] ThE_MarD:
Hmm alright, for the dialer maybe it's a feature they built into the stock dialer then to try to prevent notifications from disturbing the phone call.

I think I've seen this as well in the Google dialer from the Play store as well but I could be wrong

I noticed 1nfrag also mentioned a few pages back that codeworkX's revert for CDLA and OTG and then his attempted fix is what's causing the issues, those ones I mentioned from July 23, 2017 hmm

[MENTION=3479861]darkobas[/MENTION] do you think importing your CDLA and OTG fixes for the Le Max 2 from your OmniROM LeEco msm8996 kernel would fix the issue for LineageOS since the current version isn't working good?

Weird problem with volte and music through headphone with viper4android

To begin with, in all Lineage os 14.1 roms and RR N 5.8.4, I faced network stability issues in both the sims, especially with volte calling (Rel JIO, India). The network and volte calling works and does not work randomly, even fluctuates when mobile data or wifi turned on or off. The finger print sensor also becomes dead after some time. I found some stability when the eui modem (IN 19s or CN 21s or 23s) is flashed on Lineage OS (RR is still unstable). SO I settled with Lineage OS 14.1 (02/10/17) with modem IN 19s. Network stability is not as great as stock eui 19s but is satisfactory. Then I install Vipers4android and Dolby atmos. The problem I am facing, when I listen to music through headphone with Vipers4android on and a call comes in the Volte network (Rel JIO) there is no sound in the headphone or speaker. Also the following things happen

(i) the call automatically ends immediately (just after one ring),

and or (ii) the music sound does not come in the headphone after the call is ended.

In both cases, after the call, the network (both the sims) shows random fluctuations and volte call is never possible again. This is strange. I don't know whether this is reported earlier in this thread. I am a newcomer. So don't scold me, any help will be highly appreciated.

BTW, after flashing blackscreen kernel on Lineage, I always found only the sim 1 is detected!
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] prajjwal.laad:
The problem is with the Audio HAL. Lineage uses Open Source Audio HAL hence it has that problem. RR 5.8.5 final 1006 uses Stock audio HAL so you won't get that problem with that ROM or any other ROM like DU, Slim.
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] chetaah:
Thanks. I will live with that problem for now and hope the dev will fix this soon. BTW does this also happen without installing Viper4android or Dolby atmos?
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] prajjwal.laad:
Haven't tested it. I always use Dolby and Viper for good sound. Also, Lineage won't use the stock audio HAL in my opinion. They'll stick to the Open source one.

I also want to update to 1007. What do you suggest, a clean install or an update through updater is fine? I am a newcomer. If I take backup of "data" only in twrp and restore it after I flash a clean 1007, will I get back all my current data?

I also want to ask you, in many root apps like Kernel Adiutor, my bootloader shows as "unknown". Is this normal?
[LeEco Le Max 2 ROMs, Kernels, Recoveries, & Other ] prajjwal.laad:
I know about that issue. It happens not only with YouTube but with all the apps like instagram, facebook etc. Also, Viperfx is not the culprit over there. It happens only when the phone is heated up over 40°C.

Workaround: Reboot the phone and let it cool down. It will be fjxed for sometime and bite back again.

Fix: It is fixed with the stock audio HAL. This is the reason why I don't use lineage. Use a different ROM.

In anticipation of my newly ordered le max 2, I am trying to compile lineageos.

VoLTE Issue

Okay, so I have gone through several pages of this thread and found out that there are many users who are facing VoLTE issue.

I am able to use internet using 4G SIM placed in the second slot, but when I try to make a call, it gets disconnected as soon I dial it.

Before coming to LineageOS I have been using Indian stock ROM which didn't support VoLTE then I have updated it to Indian 19s baseband and VoLTE was working fine, but since I have installed the latest nightly build of LineageOS, it is not working.

Do I need to install and patch or any other modem file??
