GPS is not an issue for me for normal usage as it is working, though about once a week I have to switch it off and on again to get a fast lock again.

About Magisk; I can not tell as I am not using Magisk on my non-rooted boot-loader locked and very usefull and working phone... ;-)

What I want to say; where you say it is useless that is ofcourse your opinion. For other people Magisk is absolutely not needed and only giving extra security riscues and usage issues.

But probably someone else can answer your question.
[OnePlus 3 & 3T Cross Device Development] snyperius:
GPS is working fine. Not the best, but not the worst, either.

Magisk is working as intended, only thing is that so far it seems like you have to leave the bootloader open, which shouldn't be an issue if you encrypt your phone.
[OnePlus 3 & 3T Cross Device Development] :
What a fantastic phone, even after more then four years of intensive usage!
[OnePlus 3 & 3T Cross Device Development] Yudh:
@dianlujitao

Lineage os 18.1 build official 20210510

Rooted using magisk

Bug 1

Cannot unpin an app if we set long press to turn off the screen for back button

Only option to get out is by restarting the device

Bug 2

If an app crashes or freezes it shouldn't crash the whole system right

But when i used mixplorer app v6.55.5

While opening an heic image using the apps image viewer and as soon as I zoomed first the app froze and then my whole mobile and then the screen turned off just a few seconds later. (The crash happened with or without giving the app root permission)

The only way out was to restart the mobile .

The bug was solved in v 6.56 of the app but the mobile phone crash shouldn't have happened in the first place

To reproduce the crash

Steps are as follows

1) install the attached apk of mixplorer v6.55.5

2) unzip the testing folder using the app and open it using the mix app password is 'helloworld'

3) then open the image inside the encrypted folder using the mix image viewer and as soon as you zoom it the crash begins. In rare cases it begins after we rotating the image and zooming in.

I am attaching apk of mix6.55.5 and zipped folder of the encfs folder (password : helloworld)

Can't provide log sorry.

@HootanParsa 's reply below he mentions some of the system classes and functions which he used which resulted into the crash maybe this would help you.

I used LOS 17 for more than a year and never had any issues with safetynet, basic safetynet is just fine with the bootloader being locked and OnePlus 3 doesn't enforce integrity checks on its system partition. So I don't know how you had issues on that end. For anyone who is new to flashing ROMs and is thinking of flashing LOS 18 using the files inside the zip they are flashing is the easiest, also changes can happen over time so saying just patch the latest zip you have is the most ideal and most basic, anyone can figure out how to do it. I won't even talk about root since that has been mentioned everywhere why it's both possibly a security and stability issue. Sometimes you gotta think a bit outside of your own box, not everyone knows how to create flashable files or using adb.
[OnePlus 3 & 3T Cross Device Development] malerocks:
When locking the bootloader, should it be locked before the first boot or it can be done at anytime?
[OnePlus 3 & 3T Cross Device Development] :
As fas as I know it should be locked before.

Locked Bootloader Instructions

For 18.1 the instructions are the same ;-)
[OnePlus 3 & 3T Cross Device Development] snyperius:
Where did I write that I had any issues on 17.1? I wrote the exact opposite: it worked flawlessly even with the bootloader locked, which on 18.1 I have not been able to do so far. That's what I'm curious about if it got fixed with Magisk 23, just like the SafetyNet issue, which again, as I wrote, has now been fixed. And again, I had no problems with it on 17.1, hence the sentence "it used to work flawlessly on LOS 17.1".

Renaming a .apk file to .zip and installing it in the recovery after an OTA update (which still cannot be done with the solution you mentioned) is still much easier and more convenient than extracting boot images, then repacking them before manually installing ROMs. I don't think the solution I suggested would cause any trouble for anyone who has ever installed a custom ROM. But that's just my opinion.

Again, rooting my phone is not one of my hobbies. I need it for an app that I need and which doesn't work otherwise. I did acknowledge the risks when I did it, and I'm trying to mitigate them as much as I can. And as I wrote, root has never caused me any issues so far.

We can continue in private if you want (although I don't see the point as long as you are unwilling to take the effort to try and comprehend what I wrote before hitting the reply button), but let's stop with the off-topic posts here.

Peace!

Hi. Would it be possible to modify the rom to work with a non-original display? After uploading any custom rom, I have huge problems with turning on the screen. Only the bottom buttons light up ... I had to go back to stock Oxygen OS.

Adjusting brightness by sliding a finger on the status bar is broken. It works once or twice but then stops working completely and stays that way for a while.

[OnePlus 3 & 3T Cross Device Development] malerocks:
Thanks. Didn't realise that it can be locked only by a certain version of TWRP. Can't this be done by the lineage recovery?
[OnePlus 3 & 3T Cross Device Development] JoniKatita:
@dianlujitao, I found something that might help with the problem some of us have when connected to the car head unit. When the phone receives a call and I reject it, the next calls don't ring so, I tried the following:

Installed "Tasker" app, created a profile that after the call ends it sounds a "beep" through the Ringtone channel. It works. It kind of "unclogs" the channel.

Maybe it can be implemented in lineage somehow...

Best regards.

On LOS 17.1 I locked the bootloader with LOS recovery installed. Shouldn't cause any problems to do so if your phone is not rooted.

Hi people,

I just run the update, saddly, my phone bootloop actually and reboot in TWRP :(

What can i do please ?

Thanks
[OnePlus 3 & 3T Cross Device Development] Yudh:
No problem here bro. Did you checked the sha256 checksum before flashing the zip?

@dianlujitao First of all, thanks for excellent LOS. But... voice speaker is kinda broken, on maxed volume is quite silent. I tried to do clean flash - different versions of nightly, doesn't help. Speaker is hella loud on OOS, not sure what's wrong with LOS.

I found exact same issue on LOS git https://gitlab.com/LineageOS/issues/android/-/issues/3467 , tho... different phone.

Is there any chance for quick fix in next nightly? Thanks!

EDIT: My HW is in good shape and its clean, like i said i tried OOS where is working as it should

[OnePlus 3 & 3T Cross Device Development] BillGoss:
I've been running this rom for a week now. I've not had any problems with it - no system reboots, no system FCs, no performance lags or stutters (though I don't play games).

Battery life is not quite as good as 17.1, but I still only charge the phone once a day. Of course this is with the fix for the sensor_SMD wake lock from https://xdaforums.com/t/rom-experimental-lineageos-18-1-for-oneplus-3-3t.4230665/post-84465491

The only other minor annoyance than the issues I mentioned in https://xdaforums.com/t/rom-experimental-lineageos-18-1-for-oneplus-3-3t.4230665/post-84456483 is that there's no "Mark as read" option on SMS notifications.

Great work @dianlujitao! This is now my daily driver. I look forward it becoming an official version.
[OnePlus 3 & 3T Cross Device Development] dianlujitao:
Thanks for the comprehensive feedback, app stuff (e.g., mark as read) are out of my scope, maybe other devs will port it in the future
[OnePlus 3 & 3T Cross Device Development] AndroidNoobMaster:
Good day may I ask for the performance of video and audio calls? Has anyone encountered problems? I'm planning to use this as my daily driver. Thank you!
[OnePlus 3 & 3T Cross Device Development] OTAx1:
Everything working except screen goes black when using phone app. Hearing this is a common Android 11 problem. Anyone fix it yet?
[OnePlus 3 & 3T Cross Device Development] OTAx1:
[SOLVED]

Developer options

Quick settings developer tiles

Sensors Off

Quick settings (swipe down from top of screen)

Enable sensors off

No more black screen when phone in use :)
[OnePlus 3 & 3T Cross Device Development] OTAx1:
Quick Settings pull down menu works, edit panel does not; it sends you to full Settings menu for device.

Back button long press kill app not working (function of A11?)
[OnePlus 3 & 3T Cross Device Development] BillGoss:
Editing QS works fine for me when I tap on the pencil. Tapping on the gear takes me to Settings.

The settings to modify the back button functions are missing from Settings>System>Buttons in this version. I would hope that they will be reintroduced in the next version. @dianlujitao

D'oh! THAT pencil... :LOL:
[OnePlus 3 & 3T Cross Device Development] BillGoss:
Just wanted to report that the battery life on this rom is as good as 17.1. But the battery results aren't as good during the first 24 hours after rebooting.

My phone had been up more than 3 days when I took these screenshots.

Most of my usage had been reading books and using the browser. So, nothing intensive.
[OnePlus 3 & 3T Cross Device Development] lapirado:
That's a really impressive SOT. New battery?
[OnePlus 3 & 3T Cross Device Development] BillGoss:
Nope - original battery. We have two OnePlus 3Ts and haven't noticed any degradation in battery life.
[OnePlus 3 & 3T Cross Device Development] lapirado:
Thank you for your answer.

I'm getting around that in RR 10, but with a new battery.

You have any tweaks or something like that?
[OnePlus 3 & 3T Cross Device Development] BillGoss:
No tweaks, stock kernel. I don't use Google assistant (pico Open Gapps), mostly on wifi and mobile data turned off, never play games, don't use Facebook or any other social media apps.

So, not your average user, but this shows that the rom and Gapps aren't draining the battery.

[OnePlus 3 & 3T Cross Device Development] malerocks:
Is that a WiFi in your office or a place that offers public WiFi? Some WiFi networks don't allow VoIP calls which is what the message displayed says.
[OnePlus 3 & 3T Cross Device Development] Yudh:
On my phone speaker is working properly. I can't compare loudness with OOS but it is working on full volume
[OnePlus 3 & 3T Cross Device Development] Yudh:
It is working properly on my end.

Like the other user said your WiFi router must be blocking it.

Solutions that i know of

1)If it is your home or personal router try changing the router configuration if you cannot find any settings related to VoIP or calls try resetting the router.

Otherwise try upgrading router's firmware it could be because of some bug in the firmware

2) reset your phone's network settings.

3) use custom private DNS server like 1.1.1.1 or Google's dns 8.8.8.8

4) use a VPN like protonvpn
[OnePlus 3 & 3T Cross Device Development] op3tfan:
This has been a little niggle for me in an otherwise problem free os.

The activation of VoLTE on the phone.

The below mentioned method worked for me and so I'm putting it up

Paste this in build.prop

# Debug Options

persist.dbg.ims_volte_enable=1

persist.dbg.volte_avail_ovr=1

persist.dbg.vt_avail_ovr=1

persist.dbg.wfc_avail_ovr=1

# Radio Options

persist.radio.rat_on=combine

persist.radio.data_ltd_sys_ind=1

persist.radio.data_con_rprt=1

persist.radio.calls.on.ims=1

It should work.

Hi, my phone is only charging in "slow mode" when connecter to my laptop.

With some others roms it's in fast mode, any ideas why ?

Thanks
[OnePlus 3 & 3T Cross Device Development] borisSweden:
The phone has USB2.0 so propriotery charging is the only way to charge fast. If you have a USB-C port in your I/O them you get QC Charing 1 I think. 820/821 does support USB3, USBPD and QC3 but I don't know if it's possible to port from other devices.
[OnePlus 3 & 3T Cross Device Development] Nixeus2:
So, why with Arrow OS, my phone was on "fast charging" when connected to my laptop ?
[OnePlus 3 & 3T Cross Device Development] borisSweden:
Could be wrong so download a ampere showing app. Dash charging is 20 watt.
[OnePlus 3 & 3T Cross Device Development] Kurt Krummbein:
Fake?
[OnePlus 3 & 3T Cross Device Development] Nixeus2:
No, it wasn't fake...my phone charged very quickly and on the same laptop...no lie. I don't understand
[OnePlus 3 & 3T Cross Device Development] JoeBar07:
Normal charging rate for USB is 500ma which is the old USB 2 standard and for USB 3 it's 900ma. Most Boards/Ports exceed those standard so it's possible to charge with 900ma or more.

The only way I got around an ampere in Lineage while charging over PC was when I used custom Kernels and set it to USB Fast Charge in a Kernel Manager.

Maybe someone has an Idea to make the LineageOS Kernel do the same or change something else in the system?
[OnePlus 3 & 3T Cross Device Development] manichew0201:
Can anyone tell me if it is possible to uninstall a few apps from this ROM. Namely, Browser, Music and Calendar. If yes, what is the process? I would like to use Google apps as a replacement for the above. Thank you.
[OnePlus 3 & 3T Cross Device Development] malerocks:
Some of the gapps packages that you flash replace some of LOS apps with Google equivalents.
[OnePlus 3 & 3T Cross Device Development] manichew0201:
Thankyou for the reply. I tried that. However, none of the apps for replaced. Used NikGapps. Is there a particular process to be followed?
[OnePlus 3 & 3T Cross Device Development] :
In TWRP you can mount /system and remove:

- Jelly (browser),

- Eleven (Music) and

- Etar (Calendar).

You have to look in /system/app, system/priv-app, /system/product/app, system/product/priv-app, though most should be in /system/product/app I guess.

After an update you have to do the same procedure again, or you can make and run a script for it in TWRP.
[OnePlus 3 & 3T Cross Device Development] :
A question about the LOS kernel;

Why is the kernel not updated to 3.18.140 and are we still using 3.18.124?

Asking because other ROM's are mostly using 3.18.140, so I can not imagine why LOS is not...

Someone who knows and want to explain?
[OnePlus 3 & 3T Cross Device Development] malerocks:
Look at the package description in Nikapps to know what apps each package will replace. The larger the package, the more AOSP apps it can potentially replace. Of course, its not possible to replace each and every app.

You can also disable the LOS apps and download the google apps from the store
[OnePlus 3 & 3T Cross Device Development] manichew0201:
I tried the full version of NikGApps. The LOS apps were still there. Is there a specific process to be followed to ensure they get replaced? As usual, i just clean flashed the ROM and then the NikGApps.
[OnePlus 3 & 3T Cross Device Development] malerocks:
No. There isn't any specific process. Like I mentioned above, it won't replace each and every app. The other way is to disable the apps
[OnePlus 3 & 3T Cross Device Development] JoniKatita:
Hello,

I use FlameGapps (full) and it replaces/removes all LOS apps.
[OnePlus 3 & 3T Cross Device Development] Nixeus2:
Or...you can use a debloater ;) i did it to remove calendar, sms and browser. Removing too much app is bad btw, can did problem on the rom.
[OnePlus 3 & 3T Cross Device Development] Nixeus2:
Btw, i used NikGApps on this LOS....all was fine, but when i got an OTA update of the LOS.....the phone bootlooped :( so i flashed another gapps :( Don't know if it was NikGapps related. Anyone know ?
[OnePlus 3 & 3T Cross Device Development] manichew0201:
Okay. Thanks !
[OnePlus 3 & 3T Cross Device Development] manichew0201:
Thanks ! Will try that. But i hope every new update does not bring the LOS apps back.
[OnePlus 3 & 3T Cross Device Development] JoniKatita:
At least for me it doesn't. I update every time a new release comes out ant it is still clean.
[OnePlus 3 & 3T Cross Device Development] manichew0201:
Thats good to know as well. Thanks again buddy.
