I have not tested this myself, but came across the statements below.

Therefore I would not be so sure whether full eSIM support is provided.

This means, you might be able to use an existing eSIM which was configured while using Google Stock ROM with Google Play Services (and other proprietary) apps / components.

But you might not be able to add / modify eSIMs using LineageOS.

Can anyone with more practical experience tell us more facts / findings?
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] icantlogin:
The first time I used eSIM was on this (or my unofficial continuation of this) ROM, with the minimal Gapps package installed. I could add the eSIM normally, everything worked. I think the only requirement is Gapps.
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] wireroot:
Disclaimer: I am actually using

official LineageOS 20

no GApps

no root

Thank you for confirming the statement from the opening post.

Triggered by your statement, I obviously managed to reformulated my search engine query used for my previous answer and came across the OpenEUICC project from the (main) LineageOS sunfish maintainer PeterCxy from 1.5 years ago:

Since there is not even an official LineageOS 20 Pixel 4a sunfish XDA thread (only an unofficial one initiated by @mangokm40), I doubt that I as a non-developer would receive any answer at all form PeterCxy. This is why I try to profit from your @icantlogin expertise and instead ask you about your opinion / estimate:

Based on the aforementioned OpenEUICC project, which is only usable via root, do you think there is a realistic chance of actually integrating this functionality (eSIM "read+write permissions" instead of current "read-only" permissions) into LineageOS so that non-GApps and non-root users can actually handle (add + remove) eSIMs?
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] icantlogin:
Yes, that should be possible. You'd think LineageOS would do this at some point. Especially when somewhere in the next 10-20 years we'll inevitably move to an eSIM-only world (I assume). Maybe they're already working on it?

I'm trying to get LOS 19.1 on my Pixel4a. I'm building custom ROM from Lineage 19.1 with BLE privacy disabled. I need to extract proprietary blobs but first need existing LineageOS install in order to do that according to the build instructions. I can only find LOS 20 downloads now and I have to use Android 12 or lower since they changed the BT stack in 13. Anyone have any ideas? I guess I could go down to 18 and use the unofficial build that's in the other thread here, but I've already got 19.1 downloaded and patched.

Good morning/evening everybody - I'm running the October build of LOS - I was rooted with Magic and all my banking apps with safetynet passed , then I've updated through OTA and my root is kind of lost (banking apps are still working)

Should I root again with magistk? what are the steps? And what would be the way to retain root through OTA updates?

There are easier way to fix safetynet? thanks a lot

If you have modules that are useful, go ahead and reflash Magisk. It is the same as how you flash Magisk for the first time.

Hi to all,

I would like to install LineageOs 21 from stock (but no more updated) Android13 on my Pixel 4a. Since I am hearing impaired, a crucial point is the ASHA (Android Streaming Hearing Audio) protocol, that is present in stock Android 13. Is it present in LineageOS Android 14 also? Moreover, will Google Pay be supported also?

Thank you in advance.
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] treypop:
From what I understand if ASHA is supported in the stock firmware it should be supported in Lineage. Now for google pay you have to root your phone and jump through some hoops to get it to work. I don't use google pay because it's a pain to get working with Lineage

[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] icantlogin:
You can look for a mirror that still hosts older official builds. Just a few days ago I saw someone mention such a mirror on Reddit that they said is run by someone from the LineageOS team.

Hello,

I'm thinking to flash my stock Pixel 4a android 13 but I need to know if with this ROM the Pixel recognize any external DAC ? Mine doesn't, sound is OK but not HD 24bits.

Any thoughts?
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] scruffy1:
it's a great idea

i have the 4a which i have only very recently flashed to lineageOS 21 (android 14) and it works well - no experience with LOS 20 (android 13) on this device, but all the functions for usb audio and ldac were fine on a oneplus 5t

benefits include the ability to do bluetooth using ldac (which is excellent via a topping e70 dac to the main 2+1 living room system), and with data out for the usb-c setting, it drives a my small stoner acoustics ud130 dac/amp

note that you need to switch on usb data transfer in the developer options i think (or in the pull-down menu once you connect usb... bit vague as it just works on mine after numerous setups, and once it does i tend to forget why it was capable, because it just is

- no experience with LOS 20 (android 13) on this device, but all the functions for usb audio and ldac were fine on a oneplus 5t

you can do this on a standard 4a running android 13, thus :

If 'Developer options' isn't available:

Navigate: Settings. About phone. then tap. Build number. 7 times. If prompted, enter the current lock method (e.g., Fingerprint, PIN, etc.) to proceed.

Back icon. to return to Settings then navigate: System. Developer options.

from a brief look in there (just fiddled with my wife's "stock" 4a) the setting for usb audio routing is enable by default, and indeed my son's pixel 5 (no headphone jack) works by default with this usb dac

however, i know my khadas tone 1 dac will not work with any of them, as it needs a driver, which i haven't chased because i don't need it for my phone - the usb issue for you may well be the dac's need for a specific driver, not the phone's output

hope that helps
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] Tokyette:
Thank you so much but i'm afraid it doesn't work.

I tried on my stock 4a, developper mode activated. Setting usb audio routing on or off does not change nothing. My iBasso DAC isn't recognized, i just can see "cable headphones", sadly

Google Camera from stock can be installed directly on LineageOS without any sort of "porting". Just extract the GoogleCamera apk from stock and you are good to go.

Dumb question, but where can I get the latest stock roms and recovery etc.

[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] TheSayaMan:
You simply double click the flash-all.bat file and it should flash for you.
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] TheSayaMan:
You can simply just flash Lineage because Graphene is still Android 11 but you will still have to wipe device or you will be stuck at bootanimation. The stock firmware is located here: https://developers.google.com/android/images But not necessary if your staying on a custom Android 11 Rom. And it's a good question, not dumb at all.
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] miko12312:
I know how to fix it but how what steps did you take to flash grapheneos

It fails for me I notice there is one extra file in the zip
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] TheSayaMan:
What happens? Does it close back out and doesn't flash? If so, you can edit the flash-all.bat file. It does fail to flash on some win 8 or higher machines. You can left click on the flash-all.bat file and click on edit, erase everything in there and copy and paste this exactly, then save the file and it should flash fine if you were having problems.

Anyone having any issues with the latest OTA update and GPS fix in applications? I'm able to lock onto GPS just fine (GPS Status app), but when I go into Google Maps or Osmand, it won't show my position. I've cleared caches and fiddled w/ settings (e.g. turning off Google Location service as to force it to restart itself when I open Maps again), but even then it only gives me a grey dot (not the "active" blue one).
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] RogerClark:
Thanks.

I'll download the images in case I need them

I'm actually undecided now about whether I should switch to Lineage.

My primary reason to swicth to Lineage, now that an official version is available, was because the local COVID check-in App required by the government would not run on GrapheneOs.

However, I managed to fix the problem by installing MicroG Core Services, via Froid.

I also just read that GrapheneOS plan to add a dummy GooglePlayServices App, with no special permissions, which reports that the Google servers are offline, which would do the job of MicroG

However until that feature is added, it looks like MicroG is a good alternative.

Also, the AroraStore app seems to be mostly working, so I can get Apps from the PlayStore directly, and don't have to sideload etc.

Prior to installing MicroG, I noticed a some Apps would not run on GrapheneOS, but I'm hoping that now I've got MicroG installed more may work.
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] RogerClark:
I installed it about 5 months ago on a brand new phone.

From what I can recall I just ran the Bat file, and hoped for the best.

At the time I was using a Windows 7 machine, and I think it had ADB ect in the path, but I don't think the ADB stuff would make any difference.
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] TheSayaMan:
I can tell you flat out that Play Store apps that require Play Services will not run on GrapheneOS because Play Services can't run on a GrapheneOS. I've tried MicroG awhile back on GrapheneOS and those apps wouldn't run. An error would state that without Play Services the app won't run.

I currently have an S7 flat with the stock samsung oreo rom, no root or other customizations. Upon its launch, it was on par if not faster than my iphone 6s. Now, the S7 is quit abit slower in gaming and overall performance vs the 6s.

I wonder if thats due to outdated software/OS, as i understand the S7 is by default running TouchWizz? The playstore says Samsung oneUI though.

Anyway, to the question, will installing a custom rom like Lineageos or any other rom improve general gaming and app performance, or will it not make a huge difference?

I notice that the brightness levels aren't too great in Android 11 AOSP in general, the brightness levels don't get as bright or as low as stock iOS. If you've used the iOS brightness slider in iOS 11 and above you know what I'm talking about. It's pretty great. Which is funny because iDevices use LCD panels while Pixels now use Samsung OLED panels.

Try flashing a custom kernel and forcing the experimental brightness setting using Franco Kernel Manager (paid app but worth the money IMO). It will let you raise the brightness even higher BUT you could end up damaging your screen doing this...

I actually have the opposite issue. The 4a's screen brightness level doesn't get as low as my iPhone using the AOSP brightness slider, every screen dimmer app I use, including CF.Lumen keep changing the screen temperature to super cold colours at the lowest brightness which makes my eyes hurt. CF.Lumen does have temperature and custom color sliders which I'm not a fan of. I end up changing the display colours in FKM to make the screen warmer with CF.Lumen's dark filter turned all the way up so I can browse the net at night in the dark.

I'm just glad CF.Lumen still works in Android 11. So far it has no proper alternatives. Not even f.lux for Android comes close. I wonder what happened? Did people simply stop using their phones at night? I envy y'all...
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] jawz101:
I know the generic differences are. Wallpapers, ringtones, a few custom apps, and all Google apps and add-ons removed.

Basically, it's like a stripped down Android. 5 years ago, CyanogenMod had quick settings tiles, night mode screen tint, theming, privacy guard, and a few other system features. All of that eventually made it's way into stock Android so now custom ROMs really only offer taking out the Google bits... which most people then reinstall with a GApps package so really you've not changed anything. Except maybe add some crappy wallpapers, a boot splash screen, and a goofy swipe animation.

All of the innovators behind many of the custom ROMs actually moved on to work for OnePlus, Google, etc. so really Lineage ends up being just vanilla Android with some branding.
