Development [ROM][13.0][ENCRYPTION] Official LineageOS 20 for A52 4G and A72

[Flyos]

From time to time i use my mobile for phone calls
Everytime i choose a phone number from any contact, i have to wait few seconds until the dialing dialog appears. Does anybody have the the same experience?
I use only one sim card, second slot is for sd card..

I used another phone call app, it solves the issue. There's one on F-Droid, "Simple phone" I guess it's called, worked very smoothly. Google Phone works well also.

Hi Simon,

I appreciate the great job you have done to get this build running and your clear communication in this small bug.

As I'm travelling often by car, Bluetooth is important for me. Do you expect a solution soon or should I look for another phone?

Best regards, Mario

Im really not sure if i'll ever figure it out or not.

Probably a dumb question, but in the guide it states phone needs to be downgraded to android 12 before installing lineage 20, why is that ?

 

[seam0nster]

I noticed there's a new update, is there a change log available anywhere?

Thanx for the straight answer! Can I be of any help with e.g. testing?

Thanks for noticing, I have fixed that now. Android 13 is required for LineageOS 20.

Thanks for developing this ROM, Simon! I have been using it for a little while now and it works well. There is only one problem: the camera app doesn't appear to know the size of certain photos it takes. For example, every photo taken with the 64 MP main camera is supposedly exactly 73.22 MB large. All of the following info is from my A52 4G running your first official build of Lineage OS 20. When I copy the photos to my Linux computer I get the same results. Notice how the italicized cameras create photos that are both ginormous and the same exact size. As far as I know, each photo should be slightly different (as the 12MP and 5MP photos, and all videos demonstrate). Anyone else noticing this?

Camera App (Aperature) Settings: Ratio 4:3, Capture Mode - Minimize Latency, Enable OIS

All images are JPGs

12MP Ultra Wide:

UPDATE:
I just installed the "Open Camera" app on F-Droid, to see what the filesize was of photos taken from a different app, and...they are even bigger! Every photo I take with the Open Camera app is 96.22 MB large. Interesting how they also end in ".22".

Just ran into another problem. A few days ago I updated to the latest official build (1-27-23). I used some apps after I updated it, and put it away. Then, a day latter, my phone is temporarily bricked! The problem is when I press the power button, the phone display turns on, but I can only see the top bar; the rest of the display is black with a little white digital clock and time displayed. When I drag down from the top I can see the info expanding, but everything seems to be blocked by the black area. I thought I could reboot to fix the problem, but the power button isn't even fully working. I can press it to turn the screen on and off, but when I press and hold it the phone vibrates, the top bar dims, and the display turns off, not the phone. Apparently I'm not the only one that's had this happen, a quick search brings up this and this. Anyone have any ideas, only thing I can think of is let the phone die and reboot...

UPDATE (2-25-23):
It just happened again! This time I was granting Easer permissions, turned the pone off, go to use it a few minutes later and...the screen had the same issue as before! Look below at the second screenshot; you can tell it is different because the wallpaper and time/date are different. Thanks to @Ryzen5950XT I knew how to reboot it by holding voldown+power.

force a reboot by holding power and volume down

Thanks so much, I just did and it worked, unlike holding the power button.

@Simon1511 When I originally went to follow your instructions here, I was pretty surprised to see them say "Note: The following instructions require a machine running Windows 10 build 17063 or newer." I don't have a device running Windows, so I started searching for a workaround. I tried all kinds of things, including heimdall, JOdin3CASUAL, and WINE, but eventually found a solution here. I saw you were looking at this post, and I just recently posted this thread on using Odin on Linux, so I thought I would share it with you and anyone else here who doesn't have a Windows machine and needs to use Odin.

I used Heimdall to get the pit file, and JOdin3 to flash. No need to use virtual machines and such. Just use their git versions, as older versions may not support "newer" phones.

Tried using JOdin3CASUAL, but got errors about exceptions in threads, tried to fix it, but couldn't.

Since upgrade to LOS 20 the phone screen quite often remains active during phone calls, resulting in unwanted touches of buttons with the cheek.

Everything else seems to work good so far.

I know it's not the ideal solution but you could fix this with macrodroid until it's fixed in the rom.

Important notice:

in order to have data roaming, it absolutely has to be enabled in the stock OS before switching to LineageOS.

Yes, the instructions say

Make sure that you can send and receive SMS and place and receive calls (also via WiFi and LTE, if available), otherwise it won’t work on LineageOS either! Additionally, some devices require that VoLTE/VoWiFi be utilized once on stock to provision IMS.

but it doesn't mention data roaming specifically.

LineageOS is a free, community built, aftermarket firmware distribution of Android 12.1/12L, 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. Linked below is a package that has come from another Android project that restore the Google parts. 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 out Gerrit Code Review. You can also view the Changelog for a full list of changes & features.

* I am not responsible for bricked devices, dead SD cards,
* thermonuclear war, or you getting fired because the alarm app failed. Please
* do some research if you have any concerns about features included in this ROM
* before flashing it! YOU are choosing to make these modifications, and if
* you point the finger at me for messing up your device, I will laugh at you.

Installation instructions

Make sure you are on OneUI 5 firmware before flashing this ROM, otherwise the installation will fail!

Recommended
Follow the guide on the LineageOS website: A52 4G | A72

Alternative way (TWRP/OrangeFox)

1. Make sure your device's bootloader is unlocked.
2. If not done before, flash blank VBMeta with Odin in AP slot.
3. Make sure to have the latest available version of TWRP/OrangeFox installed.
4. If wanted, backup all your necessary partitions (super, boot, data, EFS) before flashing this in case something goes wrong.
5. Download the lineage build for your device from the link below and optionally download your preferred GApps package too.
6. Flash the LineageOS zip using the "Install" button.
7. Optionally, flash Gapps right after.
8. Format data in TWRP/OrangeFox as the very last thing, otherwise you may end up in a bootloop if coming from stock ROM.
9. Wipe metadata and cache partitions. This only has to be done once when you install LineageOS.
10. Reboot
