Battery life seems better with blu_spark kernel but after 6 hours since last charge, kernel keep awake phone during more than 2 hours.

noise cancelling microphone problem

Hi.

Firstly, big thanks to all devs working on LineageOS for OnePlus 5T.

I have a problem with noise cancelling microphone. I'm running LOS 15.1 (microG build) and during calls the second microphone (located near back camera) collects all voices from background (being very sensitive) and transmits it so the caller hears everything (along with own words which get recorded from the earphone. Noise cancelling seems to be disabled.

It is somewhat opposite to the common problem with older OnePlus phones where noise cancelling was too strong it cancelled the voice of person speaking to the phone (Google for fixed-for-good-microphone-issue.222059 topic on OnePlus forum - I can't post links yet)

I tried modifying build.prop and audio_platform_info files but it didn't work. Has anyone had such problem?

Is streaming aka. screen mirroring working on this rom?
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] choukajohn:
I think to know why I have battery drain.

When phone is idle with WiFi activated, I lost 10% battery by hour.

When I deactivate WiFi, battery drain is only 1% by hour.

I never had this situation before, WiFi has always drained less battery than being connected with 3g/4g.

Changing kernel by blu_spark didn't helped with battery consumption when phone is idle.

Please, what can I try to do to solve this issue ?

Thx for your help.

Kernel going nuts when wifi is on doesn't sound normal. What firmware are you using?
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] MakeHav0:
Thanks for the maintainer of this rom. When I am using LineageOS, I feel like my phone is actually tool. Snappy as little baby fox and no junk features which are causing bugs. Had just one FC but it was no biggie. Solid ten out of ten.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] choukajohn:
Hi,

I was on OOS 5.0.3 before flashing LineageOS.

I don't think it's normal, look at my CPU usage, even when WiFi is turned off.

Screen on, doing nothing.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] choukajohn:
Ok I tried to uninstall Magisk root and it solved my CPU usage problem.

Last LineageOS update I didn't flash Magisk because root survived ROM update, maybe it is related to this issue.

I will try to enable WiFi again and let you know if problem is solved.

So how are we going to get there? I don't think any ROM here uses that, so data has to be re-formatted, right? Will that be done in TWRP?
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] codeworkx:
All 8.1 based roms do.

Dunno how we'll handle that. Formating data helps.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] the Doctor:
I'm on Omni 8.1 right now, came from OOS 8.0 Beta. No formatting was required. I could flash back to OOS Nougat without formatting data if I wanted to. That's why I suspect that it uses keymaster1.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] codeworkx:

As previously mentioned, fingerprint is no available option in the security settings.

At OmniRom, they apparently solved that problem by setting SELinux to permissive (https://xdaforums.com/showpost.php?p=74757168&postcount=195).

It seems I can't sideload apps. Clicking apks in the basic files app doesn't show a popup as usual about trusting this app for installations..

Hello everyone!

Just tried to install the update via TWRP, but it fails at decrypting data. It says that my Decryption Pin is incorrect, but it's the same that I use for Screen Lock.

Then, I removed the Pin and TWRP could decrypt Data with the standard decryption password.

So, is this a known issue or is it my fault?

I have updated to latest LineageOS version and removed root, I can confirm I doesn't have CPU usage issue anymore or WiFi battery drain.

I tried several versions of Magisk and I also tried official LineageOS addon to root and all have the same CPU usage issue.

Anyone have the same issue with rooting LineageOS?

microphone problem during calls

Hi,

if anyone else struggled with microphone problem during call (when back microphone located near camera collected and amplified all sounds from background along with voice of caller from the phone's headphone) there is a quick fix which worked for me:

Change following line in /system/build.prop

persist.vendor.audio.aanc.enable=true

to

persist.vendor.audio.aanc.enable=false

Root access is needed (su or ADB with TWRP Recovery)
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] rijads:
No, my battery life has gone way up from OOS, I never got more than 5hours on screen time on OOS, and I am getting 6h with lineageOs, with magisk for adaway and camerafix and stock kernel.

And all this with bright theme, I don't notice any improvement in battery when using dark themes either.

If I'm upgrading from OxygenOS 5.0.4 to LineageOS 15.1, will keystore be updated or is it still using keystore1 then? Is there a way of confirming which keystore I have? Would it even make a difference security-wise? :)
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] giddie:
Just quite curious: given that the hardware on the 5T is presumably pretty much perfectly consistent, why is it that we see variability in the issues that people are facing? Presumably this is down to not starting from completely wiped system / data partitions?

Thanks for the good work.

Coming from a Pixel (1) phone, my first requirement was Monthly security updates, followed by a pure Android experience.

And I have all of that.

My setup:

* LOS 15.1 (coming from OOS 5.04)

* OpenGAPPS official, stock 8.1

* Magisk 16 (mandatory for banking app)

* Using Codeworks TWRP

No battery issue, nor WiFi, Bluetooth or anything. Works perfectly with my Zenwatch 3, different Bluetooth headphones, car (Android auto, even Pioneer AVICSync works, this wasn't the case with the Pixel).

So I am really happy with my new phone. :)

Maybe anyone could confirm this: when looking at the phone through a camera I notice that the proximity sensor seems to constantly be on when the display is off. As soon as I hit the power button or fingerprint scanner, it turns off and comes back on again as soon as I lock the screen. Upon noticing this, I deactivated any live display and ambient display settings, makes no difference. Is this how it should be? Or could this be an explanation for (my subjective) high battery drain?

[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Dazed No More:
Call quality/clarity with headset/phones is absolutely excellent for the most part, so thank you for this. :cool:

Ive found that it is not the rear microphone that picks up and amplifies background noise through the headphones incall but the regular mic near the headphone jack, as it does not disable when using a headset with inline mic. As a test I tried the wrong way described above and it did nothing.

As another user reported a lot of times when making a call with headset it sounds like chipmunks or a VHS on fast forward. Unplugging and replugging the headset solves this, if you dont unplug then it is impossible to make a call.

Edit: I use headphones a good majority of the day while working, so I went about looking for a fix and found that by changing the "voice-anc-headphones" ANC HPHL/HPHR Enable Switches in mixer_paths_tasha.xml to "0", it disables the bottom mic incall and solves the problem. Afterwards I test called a few people who said everything was crystal clear...could doing this unknowingly affect anything else?

I'm having this issue too. On OP5t, latest nightly of dumpling. I found that unplugging/plugging in headphones during a call stops the rear mic from recording all sounds, but moves it to the bottom mic instead (as you mentioned Dazed). I tried the Android Mic Fix module on Magisk, but no luck.

Likelihood this is fixed on the next nightly? I make calls all day and it's been horrible for my work because everyone I talk to can hear everything happening in the background and can barely hear me.

If not fixed on the next nightly, i'll have to start adjusting the mic values/paths to see if anything works.

Hey guys!

Finally found the time to switch to LOS from Open Beta 4.

Super Rom. Thanks for your hard work devs!

A couple of questions though.

First, I noticed a 'bug' that I first noticed on Beta 1 and then was fixed on Beta 2.

It is best described here. Basically if you are using your phone outside the navigation bar and then quickly press home or any other button on the navbar, it just won't respond. After a second it will start responding. Really strange... Does anyone have the same experience? I tried flashing different firmware files but didn't help. Now I am on Oreo's 5.0.4

Second, regarding the camera. Since Gcam has the dots issue, any other alternatives? Or should I just stay with Snap?

Thank you in advance!

Yes. I flashed yesterdays weekly. But the issue was first noticed in the previous build, after a clean install coming from Beta 4

EDIT

Just tried from scratch. Clean flash, rom and open gapps. Still having this lag when touching the screen and then immediately pressing the navigation bar
