I don't know what to do🥲..

i have that problem
[Samsung Galaxy A21s ROMs, Kernels, Recoveries, & O] grccorps:
Hello,

I would like to thank everyone for sharing their reviews of this ROM.

This ROM is getting updated every week, so if you are experiencing some bugs, it might be fixed by installing the latest build from the OP.

So far the changelogs since July 29 release have been:

- Resolved errors related to thermal control and battery

- Updated GPU drivers

- Added code to lessen battery usage

- Fixed some issues with Camera (saved pictures were way bigger than those from stock)

- Added support for Binary version U6

- Added support for Dynamic System Updates

- Fixed Camera problems in DSU mode, and increased DSU data partition to make it more usable

- For every build, synced in latest LineageOS source code to get the latest Lineage OS changes and Android security patches. (ex. from 08/07 builds, security patch level was increased from 2021-07 to 2021-08)

As of now, I'm trying to figure out the cause of the volume and crash issues. Unfortunately, my device is not affected by these issues, so it is somewhat tricky to find a solution to this. (A217N's hardware is somewhat different from A217M/A217F, as it has lower RAM/Storage, no dual SIM, and some CSC-related changes for Korean market. One possible reason for the bugs may be due to the fact that the blobs / kernel settings were for A217N)

Would it be possible for anyone to get the log from UI crash (or any other instabilities such as reboot)? In order to get the log, when you are experiencing UI crash, please follow these steps:

1. Connect your device to ADB

2. Open command line or terminal

3. run 'adb logcat -b all -d > log.txt'

and post the log.txt on this thread. It would give a very useful clue in solving this problem.

Also, if you experienced a reboot/kernel panic/BSOD/or any other similar issues, please follow these steps:

1. In the developer settings, enable 'Rooted Debugging'

2. Connect your device to ADB

3. Open command line or terminal

4. run 'adb root' and wait for a second

5. run 'adb shell cat /proc/last_kmsg > last_kmsg.txt'

and post the last_kmsg.txt on this thread.

I am very sorry for the inconvenience caused by the bugs. It would be very thankful if you could give a log that shows the problem.

Thanks , this update include core clocked at 2.21mhz?
[Samsung Galaxy A21s ROMs, Kernels, Recoveries, & O] prestigexda:
Are the updates on the LineageOS Updates setting or do I need to flash with odin every time, also should I enable the Update Recovery Setting in the Updates?
[Samsung Galaxy A21s ROMs, Kernels, Recoveries, & O] grccorps:
Unfortunately, you will need to install it via adb sideload, as the LineageOS updates setting is only for official builds. However, you don't need to use Odin, as you would already have Lineage recovery installed if you are on LineageOS. Just reboot your device into recovery, adb sideload the latest rom and Gapps, and reboot the device.

Also, you don't have to enable update recovery option. You could enable it if you want, but it doesn't really do much, as Lineage recovery is pretty much the same throughout every builds. You should NOT enable it if you have other custom recovery (TWRP, etc.) installed, as it will overwrite it.
[Samsung Galaxy A21s ROMs, Kernels, Recoveries, & O] grccorps:
Unfortunately, the ROM doesn't come with overclock by default. A separate OC kernel is wip.
[Samsung Galaxy A21s ROMs, Kernels, Recoveries, & O] prestigexda:
Is there a way to keep all the data on the phone when updating builds??
[Samsung Galaxy A21s ROMs, Kernels, Recoveries, & O] grccorps:
You don't have to wipe data when updating builds. You only need to reset when you are coming from stock or other rom. However, it is better to back up as there can always be issues.
[Samsung Galaxy A21s ROMs, Kernels, Recoveries, & O] NuzzaimStark:
is this build also support root?
[Samsung Galaxy A21s ROMs, Kernels, Recoveries, & O] grccorps:
All builds are NOT rooted by default. However, if you want root, you can always use Magisk to root the device. All builds are compatible with Magisk.
[Samsung Galaxy A21s ROMs, Kernels, Recoveries, & O] NuzzaimStark:
i found a bug when install module in magisk, like last build there was no problem

Edit : FIXED
[Samsung Galaxy A21s ROMs, Kernels, Recoveries, & O] Mohinesh:

[Samsung Galaxy A21s ROMs, Kernels, Recoveries, & O] ElectrptheExpert:
I found out that you can actually install Lineage os on a21s by using SD card (no adb sideload)

By Clicking "Apply Update On Sdcard" Option from lineage recovery. Maybe this works only if you have sdcard. (Tested on SM-A217F)
[Samsung Galaxy A21s ROMs, Kernels, Recoveries, & O] MevishL:
I have A217F. after successfully installing lineage os. dual sim is no longer working. how can i fix that
[Samsung Galaxy A21s ROMs, Kernels, Recoveries, & O] prestigexda:
Thanks I was actually wondering if you could do this I might buy a sd card then.
[Samsung Galaxy A21s ROMs, Kernels, Recoveries, & O] ElectrptheExpert:
Actually this lineage os build was for Korean Version of A21s (A217N) which is it only has 1 sim card slot on that model. The developer is currently working on that problem.

[Samsung Galaxy A21s ROMs, Kernels, Recoveries, & O] @maxche:
Thank you for your work, very good rom. And when will there be new updates? =)
[Samsung Galaxy A21s ROMs, Kernels, Recoveries, & O] grccorps:
Hello everyone,

I'm really sorry for not responding for several days. Have been busy recently, since the new semester started ㅠㅠ

After some research, I think I found out causes of several bugs (including audio)

Also, I think I need to clean up the sources for this ROM, as I haven't done so since I started working on it in July. Some thing have gotten messed up in the middle.

Right now, I'm completely reworking the ROM. This might take several days.

Again, I'm really sorry for all the inconveniences caused by the bugs. I'll try my best to do this asap.

+ On the volume issues:

While testing on my device, I found out that the maximum volume was smaller than that of stock (when compared to S21 or S7). Disabling AudioFX (or changing it into different setting other than "Small Speaker") made the sound louder. However, I also found out that the sound was louder when using some libs from stock, so I will try to get it fixed that way on the next release. Until then, disabling audiofx might be a temporary workaround for this problem.
[Samsung Galaxy A21s ROMs, Kernels, Recoveries, & O] ProgrammingPleb:
Hi,

Thank you for your work on this ROM! I've seen the last post about the crashes so here is the latest last_kmsg that I was able to grab.

Usually this crash would happen shortly after the SystemUI would start being unstable, it is very uncertain when the SystemUI would start crashing so I do not have the logcat for that yet, but will update the post when I can get that too.

Edit: Added the logcat for SystemUI since it crashed directly after making it sleep after first time unlock.

Seems like this would be the source of the crash:

Hi there,

I have the same device as yours (A217F/DS), had the unoffial lineage OS 18.1 flashed with gApps, the phones performance is excellent and love the features, however one issue bloggles the mind. When connecting to my cars bluetooth or headset the music plays fine but when I receive calls I cannot hear the other person and that person cannot hear me. Is there a fix to this as I might just go back to stock ROM as I need my headset to function when I am at work. Also the devices sound is now lower then usual.
[Samsung Galaxy A21s ROMs, Kernels, Recoveries, & O] Maxis89:
