LineageOS is a free, community-built, aftermarket firmware distribution of Android 11, which is designed to increase performance and reliability over stock Android for your device.

LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. You will need to provide your own Google Applications package (gapps). LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit our Gerrit Code Review. Your changelog is whatever was merged into gerrit.

Important information:
This thread is for LineageOS 18.1 builds for OnePlus 3/3T. The following will not be supported here:

• Custom kernels
• Mods
• Xposed

We don't support Xposed and any logcat which includes an Xposed module will be ignored. You're kindly invited to not report bugs if you:

• Flashed a custom kernel

OP3 is my daily driver..
Thank you @dianlujitao

 

[Keyvannn]

Yes, you should

 

[Jan_L]

Yes, you should

Would updating to official builds be possible later on, based on the fact public keys are used?

Other question; is a locked bootloader possible with these builds?
I don't know enough about used keys to be sure...

Yes, the key for signing the build doesn't matter.

My initial testing of this rom is that everything is working (based on my usage): WiFi, phone calls, SMS, NFC (Google Pay) all work.
I had a bit of problem setting the wallpaper initially (FCed), but the problem went away on its own after waiting a bit of time.
I'm missing the settings option to specify the duration of the capacitive key backlight, but that's no big deal.

I'm using Opens Gapps pico 210130 and Magisk 21047.

I've seen evidence of the sensor_SMD kernel wake lock issue that I've seen on all Android 11 roms I've tested previously. I'll post more details on this once I've captured a logcat of the problem.

sensor_SMD kernel wake lock issue

Nap time by Franco mostly solved this for me.

 

[OTAx1]

Sideload TWRP 3.5.0, wipe dalvik & cache, flash 18.1. All good

Update to official build requires a clean install and an unlocked bootloader

Nap time by Franco mostly solved this for me.

Last time I used NapTime, it drains more battery than it should and my phone was almost all the time in idle untouched with WIFI and everything else off

Regarding the sensor_SMD wake lock:
Generally, the rom can go for long periods without this wake lock showing up:

But the wake lock can start at random times:

And when it starts, it will stop the device from going into deep sleep (look at the "Awake (Screen off)" figures). This will drain the battery a lot faster than normal. See 210209-174541-log.zip for logs.

However, I find that the wake lock will always start when the phone is fully recharged (I usually do this just before I go to bed). See 210209-174541-log.zip for logs.


Fortunately, a reboot gets rid of the wake lock.

Update to official build requires a clean install and an unlocked bootloader

If the plattform key is changed a clean flash is highly recommended (though not required if you use a migration script or zip - NOT!!! recommended). Since los recovery (as well as current twrp for that matter) and los boot image are signed with aosp verity key, you don't need to unlock bl if you run any version of los with a locked bl.

I've explained the three different keys and signatures used in a single build in depth in the llos 17 thread: https://forum.xda-developers.com/t/...or-oneplus-3-3t.3990061/page-60#post-82568467

Nice finding. Just check the source and that should be the Significant Motion Detector if I'm not wrong. Dunno if there are any drawbacks but you should be able to disable it by adding " ro.vendor.sensors.smd=false" to /vendor/build.prop, please try if it helps.

I set the property as you suggested. After more than 12 hours, including a full recharge, there's no sign of the wake lock. It's looking good.
Thank you!

May be a stupid question and definitely not belonging here, but can not find the answer anywhere else....
When is /vendor/build.prop used and when /system/build.prop?

It seems settings of /vendor/build.prop are used earlier in the boot process and are vendor specific, where afterwards /system/build.prop settings are added later in the boot process and are OS specific.
A lot of people are messing with build.prop settings but have no idea what they are doing and if settings are even working or not. As I see it, some settings put in /system/build.prop are in fact settings which belong in /vendor/build.prop, but I do not know if everything put in /system/build.prop will overrule /vendor/build.prop or the other way around....
In some Android 10 code I found the order default.prop, build.prop, vendor.prop, where /vendor/build.prop is loaded after /system/build.prop, though not sure if this is the default then....

You see, no idea what I am talking about; I hope someone can clear things up...

First of all: since op3/t has no dedicated vendor partition /vendor is a symlink to /system/vendor.

/default.prop is read first and contains settings necessary for basic boot (historically this file has been part of the root partition which has been ramfs contained in the boot image as cpio archive prior to system as root, which allows to set these props before system was mounted - obviously that's not longer the case with system as root.

/system/vendor/build.prop is read as second source containing vendor specific props. Systematically this should contain settings specific to the vendor(s) of the device and the actual os (which are the same, as long as you use stock roms, but obviously differ if you use an custom source build rom like los).

/system/build.prop is reaf as third source and should contain general android settings.

If the same prop is set in more then one file the last one wins as long as it's no read only prop (ro.*). For ro.* prop the first one wins, because it can't be changed after setting. Exeption: if you use magisk, you can alter ro.* props (by command from the commamdline or a script).

Additionally to these three sources some props are set by init (first os process started by the kernel and controlling the boot process). See:

Thanks for the clear explanation nvertigo!

 

[unnilinux]

Does this rom support encryption?

Thank you for your hard work and look forward to the arrival of offical los18.1.
