Does LOS recovery allow for full system backup/restoration?

I am running stock Android 12 (rooted with a lot of customization that I don't want to setup again if I don't like LOS).

Nope.

Is anyone running the latest version of LOS19 (lineage-19.1-20220623-nightly-sunfish-signed.zip) ?

I'm asking because there's this VVM issue open for a OnePlus7, running LOS18.

VVM is working for my 0616 build of LOS19, and the issue mentions it broke when they installed their device's 0619 build. Thus, I looked at the list of changes for our device here.

There are 5 changes to "android_packages_apps_Contacts".

There are also many changes to "android_vendor_lineage" that mention APN changes for various carriers.

I'm wondering if anyone is running the 0623 build & has VVM working.

Thanks.

Missed Calendar notifications & Trebuchet's 'Hidden apps'

1)

I found this way to fix my Calendar notifications in LOS19. I'm posting it here, in case someone else was having the same problem.

2)

If you've missed 'Hidden & protected apps' since your move to LOS19, there appear to be good news. The 'Changes to be included in next build' includes 'Trebuchet: implement hidden & protected apps'. WooHoo! :)

4a LineageOS 19.1 Update 2022-07-14 - Security Bump, Calendar Update, Hidden Apps

Using the built-in Updater, I OTA-updated Pixel 4a (Google Ed) LineageOS 19.1 sunfish build 2022-06-16 + lineage-19.1-20220616-recovery-sunfish to build 2022-07-14. I have no GApps, no custom-kernel, and Magisk is not installed. Everything went smoothly. I used 'Caffeine' & the "install" part took 11 minutes.

There are a bunch of changes as you can see here.

The ones that I noticed are:

1) Security Bump - see details below.

2) Calendar Update - the update to version 1.0.30 didn't clear the search crash problem. The battery use is now forced to "Unrestricted", to allow all notifications to appear on time.

3) Hidden & Protected Apps - It remembered all my hidden apps from LOS18 & they were hidden without needing any new input from me. WooHoo! :)

After the reboot, I went to Settings->About phone->"Android version". The "Android security update" now shows "July 5, 2022".

The Vendor security patch level (just below) is also "July 5, 2022".

The Build number at the bottom is now "SQ3A.220705.003.A1".

The Baseband remains as "g7150-00090-220406-B-8411773".

See Android Security Bulletin - July 2022 for details about the security fixes.

I rebooted to recovery to verify that it was also updated. It now shows version "20220714" and active slot 'b'.

Hello, can someone help me with the following question?

* Does Google Pay / banking apps work good with this rom? I suppose that magisk is needed along with some safetynet fix?

Thanks!
[Google Pixel 4a Guides, News, & Discussion] Joojoo1993:
At least I am running Google Pay and all my banking apps fine with:

- Magisk v25.2 with rename function

- Modules: Universal SafetyNet Fix, MagiskHide Props Config, Shamiko

- All relevant Apps on Magisk deny list

- Renamed Magisk script /system/addon.d/99-magisk.sh to something else

- Magisk freezed with Ice Box App

If all apps really require all steps above I did not check...

At least one App (of my health insurance) requires all of them.

Edit: Multitouch not working anymore. Seems to be a widespread problem with Pixel 4a: https://piunikaweb.com/2021/02/03/p...issues-yet-to-be-fixed-after-december-update/

Need to ask about this:

Most of the ROM seems to work great, but I have a tiny issue.

I'm using VoWifi all the time at home and it works great. Outside range, I use normal service.

My issue is when I move from wifi range on a VoWifi call, to outside range. The call always drops and I need to call again.

Shouldn't the phone be able to switch from wifi to other service in a call without interruption?

Or is something wrong with my setup?

Kindly
[Google Pixel 4a Guides, News, & Discussion] mangokm40:
I'm an idiot, so I can't help. :) But it might be useful to post details about your setup. Someone knowledgeable might have good information.

IE: "I'm using VoWifi all the time at home" - Does this mean you have your "Calling preference" set to VoWiFi? Have you tried changing this preference?
[Google Pixel 4a Guides, News, & Discussion] jontis:
Yes, my preference is VoWifi at home. Inside my apartment, cellular reception is really bad, but wifi is good. Outside cellular is good, but wifi is bad. Thus my preference to VoWifi at home. Calls don't work without it.

It is as in the thread lineage 19.1, and the device is sunfish. I've seen it at many different updates during this year.

4a LineageOS 20 Update 2023-01-26 - OTA failed

I set caffeine on for 30 minutes.

The download was successful. However, the installation stopped about 55% of the way into "Finalizing ..." (the last step). Caffeine expired (30mins). I set it again for another 10min. The update never continued. I clicked 'Cancel'.

Thanks for all you detailed work, mangokm40 - this is really the OpenSource-Community vibe we need :-)!

My wife is getting her 4a by the end of the week and I'm wondering, which LOS version would be the one to go with, as I can't tinker with it all day.

Is LOS 19 considered stable enough so that I could grab the latest nightlys?

Or can anyone suggest even a LOS 20 build without issues?

Thanks in advance,

Guntram
[Google Pixel 4a Guides, News, & Discussion] mangokm40:
The day after my failed OTA, I got a VoWiFi error, while connected at home.

I've attached a screenshot.

Since I've never seen this error before, I thought it was the failed OTA.

Restarting the phone had no effect.

I was getting ready to do a clean install of LOS20. However, I visited a family member

who is using LOS18 & the same carrier as me. That phone worked fine.

I connected to that WiFi. My phone worked fine, no more error. :)

It's now working at home. It's been more than 3 days now. :)

I'm going to keep waiting before trying a clean install. Since I created an issue for

visual voicemail, it would be nice to be able to test any work that is done. :)
[Google Pixel 4a Guides, News, & Discussion] mangokm40:
Since you're going to be doing a first-time (wipe/format) install, you could try LOS20.

If you get the VVM (or any other) error, you could always do the steps again with LOS19. :)

I had no trouble with LOS19. You wouldn't be getting updates, however.

There's also an unofficial LOS18 here. If you decide to use that, just make sure to read

the thread carefully, in case there's a different installation procedure. User "icantlogin" has

been building that with the latest Android updates (I think).

After speaking to a friend, I uninstalled "KDE Connect" app. It was the only thing I'd installed right before updates started failing. I set caffeine to 30 minutes. I also had the phone plugged into the USB in my PC (charging). Although the update was slow, almost 30 minutes, it completed.
