Hi @danwood76 , Zram is used , so 950M "swap" compressed to 5M in RAM which is not possible, >100:1 comression ratio.

ZRAM: 5,380K physical used for 957,120K in swap (1,044,736K total swap)

Usually compression ratio 2:1 or 3:1. See above for SM-T530, or here Android system taking all memory | XDA Forums

I haven't rooted the device, so can't see /sys/block/zram0 statistics and parameters you configured for zram

Hi @danwood76 ,

thanks a lot for your awesome work! Just got the battery of my A3 replaced by a new one and want to upgrade from 17.1 soon. Before that, it would be nice if you could answer some questions:

1) Will the unofficial 18.1 ever become official?

2) With the unofficial version, will I get updates as easily as before?

3) I currently have LineageOS for MicroG. Will your upgrade instruction work in this case? (I don't need to have MicroG.)
[Galaxy A3, A5, A7, A8, A9 Original Android Develop] kurtn:
In your case i would stay with 17.1 - microG stll builds updates. And they are easier to install than unofficial 18.1 builds.
[Galaxy A3, A5, A7, A8, A9 Original Android Develop] :
I know that this shouldn't be posted here but I have not got an answer when posted in 17.1 thread. I recently installed Lineage Os 17.1 on the a310f using the recommended install method for first time use. After I went through the set up, I noticed that the imei number was gone. After a few days it came back but disappeared every time a sim card was inserted. I did some research and found that flashing the stock rom would fix it. I restore stock from a twrp backup and the imei number was back but no sim card was detected. signal bars appeared before putting in a sim card but connection would disappear as soon as sim card was inserted. I then tried flashing the single file firmware for the device with odin but with no success. I tried installing Advanced Three based on stock, then back to Lineage but the problems still occur. Now I'm unable to use a mobile network. What should I do now? Forgot to mention that the sim cards I tried work on other devices but not this one.

What version of stock were you running before you went to LineageOS?

Sounds like either a hardware issue or maybe even SIM lock issue. Have you tried a SIM from a different network?

Have you ever had the phone unlocked by a third party? Sometimes they use hacks that can backfire later.

Kind regards,

Danny
[Galaxy A3, A5, A7, A8, A9 Original Android Develop] :
I was running the latest version of stock on 7.0 nougat before installing lineage.I have tried sims from the default carrier and from other carrier's but it is producing the same result. I did unlock my device using a puk provided by my mobile network but not even original is detected.
[Galaxy A3, A5, A7, A8, A9 Original Android Develop] danwood76:
I have juts taken a look into what the numbers actually mean (to check they are not miss counting).

The "3,476K physical used" looks like it could mean the number of memory pages used. It is based on a counter and may be inaccurate (it collects these stats as it goes). I have been playing with a memory filler and the numbers go up and down with usage but I'm not entirely sure that first number indicates what you think it does.

If you are getting the OOM to kick in then you are filling your RAM and SWAP. I would suggest removing apps you are not using.

Kind regards,

Danny
[Galaxy A3, A5, A7, A8, A9 Original Android Develop] ginodman:
I have quite few apps and they return memory after use and clear recent apps. OOM is involved because of system process is getting bigger and bigger.

I provided above the similar device matissewifi with these numbers

ZRAM: 50,012K physical used for 158,580K in swap (1,066,392K total swap)

50,0012 is resonable for 158,580K, 1:3 comp ratio
[Galaxy A3, A5, A7, A8, A9 Original Android Develop] danwood76:
You are comparing apples and oranges. They are different devices, different kernels, and different drivers. Maybe there is a bug in the reporting in our kernel but I would guess that the "physical used" statistic is probably incorrect.

If you are seeing the high system usage after an oom then it is likely ram that is being garbage collected and is cached.

I will take another look at this but from my testing today or all seemed to work correctly and the used swap was correct even if the info in dumpsys doesn't seem to add up.

Danny
[Galaxy A3, A5, A7, A8, A9 Original Android Develop] ginodman:
To speed up system process taking and not returning memory I run hungry apps like Firefox, Maps, Gmail in parallel not closing them. And then when I close them all I can see Android System is using more memory with each iteration.
[Galaxy A3, A5, A7, A8, A9 Original Android Develop] danwood76:
Looking at the kernel source for that device it does have a similar backport of zram. I will compare to see if I am missing a patch.

Kind regards,

Hey! I confirm that system process LOS 18.1 use ram that getting bigger and bigger of every day. I think the problem is not only old kernel. LOS 17.1 haven't this memory leak bug. I tested LOS 18.1 kernel used zram and zswap and got the same result.
[Galaxy A3, A5, A7, A8, A9 Original Android Develop] sbocconi:
Thanks @danwood76 for your work!

I see that in the Mega folder there are regular unofficial releases of LOS 18.1 for a5xelte, the latest on 3/15/2022.

Do you plan to continue releasing new versions?

And is there a way to update to more recent unofficial LOS18.1 versions when they are released, without having to perform the full upgrade described in the beginning of this post (thus also flashing OpenGapps, and reinstall all the other apps)?

Thanks,

Stefano
[Galaxy A3, A5, A7, A8, A9 Original Android Develop] HeladeraDragon:
Is this stable enough for me to use in my daily driver? I have an a5xelte and I'm currently running LOS 17. It is stable enough for me to daily drive, except for random restarts when Bluetooth is enabled, and i'm connected to a device. I don't expect LOS 18 to fix this issue but I want to know if it is good enough for me to daily drive, also what is the difference between an official and unofficial LOS releases?
[Galaxy A3, A5, A7, A8, A9 Original Android Develop] danwood76:
There shouldn't be random reboots when connected to BT devices. That has never been reported to me.

Most users report 18.1 is more stable than 17.

Hi,

New update uploaded.

Changes 26-04-2022:

Synced to latest LineageOS source (including April security patch)

I have been unable to reproduce the "system consuming ram" issue. Maybe it is triggered by a particular app or gapps version. I tested with the latest opengapps Pico from a couple of weeks ago.

Kind regards,

I clean flashed this last update with Magisk.

I realize I'm gonna need gapps. Can I flash now? How? Which version?
[Galaxy A3, A5, A7, A8, A9 Original Android Develop] kurtn:
You think you need GApps because you don't have an app store and no contacts? Or do you really need the full control of Google over your phone?

For GApps do a factory reset and flash an arm 11 version
[Galaxy A3, A5, A7, A8, A9 Original Android Develop] Pierre49976:
No, nothing like you describe.

I've used LineageOS for a long time without gapps (2 or 3 years), using fdroid and Aurora Store. I use Zaclys to sync my contacts via nextcloud.

But some apps doesn't work without Play Store like OsmAnd Online GPS Tracker or Pony.

Doing a factory reset is going to erase all my installed app, right? I don't really have the courage to reinstall all, as I did that 3 or 4 times during the last week.
[Galaxy A3, A5, A7, A8, A9 Original Android Develop] RTCH:
Tested this on SM-A710F (a7xelte) with Full OpenGApps works pretty well, using other version than Full GApps break many features

The Play Store sometimes won't work, Random Download Stuck or just Pending and Google Assistant does not able to communicate with other Smart Devices properly, and the Microphone seems to not have any tuning or enhancement so it sounds horrible compared to stock but that's a minor thing

Thank you for this Custom ROM that makes my phone way way more usable than the Stock TouchWiz infected one lol
[Galaxy A3, A5, A7, A8, A9 Original Android Develop] pixelou:
EDIT: NVM, it is opengapps which get stucks, flashing lineage alone works.

Hi. Upgrading from Lineage 17 I get the following issues during setup:

- Network error even though it successfully got connected initially

- When selecting offline installation the setup screen enters en endless loop animation saying "one moment..."
[Galaxy A3, A5, A7, A8, A9 Original Android Develop] pixelou:
Did anyone experience a similar issue setting up opengapps?

EDIT2: I was able to skip the setup wizard by tapping the edges clockwise. Turns out google play service is missing even though I installed Gapps pico. Weird...

EDIT3: turns out the latest release of OpenGAPPs is broken, the previous one from february works just fine.
[Galaxy A3, A5, A7, A8, A9 Original Android Develop] JPCastillo2000:
For zram getting full, maybe mounting the RAM device with the "discard" flag could prevent it from getting filled with useless data, as per:

https://www.reddit.com/r/linux/comments/u0hb2a

As for it begin unused sometimes, unfortunately older kernels can't use zram as efficiently as newer ones, due to them lacking a patch included in newer kernels that adjusts vm.swappiness to better handle zram scenarios, as per this answer: https://unix.stackexchange.com/ques...-more-memory-compared-to-its-compressed-value

Also, for people running out of memory too often, a full memory system zram device might be useful, as per the same Stack Overflow answer. This is the default configuration on Fedora Linux, so it should be safe to use. I've been using both configs (discard + full RAM zram) without issues in all my devices.

In my opinion, it should be an official version.

I have tried a 19.1 version, phone calls were quiet impossible.

Thanks again.

One sentence from the setup process is confusing me:

If this is your first time on a LineageOS ROM format data, you also need to have been running your latest stock OS version

Currently my A710F is running S Cube Redefined ST with Android 7. I have downloaded the file "lineage-18.1-20220426-UNOFFICIAL-a7xelte". My question is can I go and flash it right away through TWRP or do I need to first install the last stock rom available with Odin and then flash it?

Hello, and thank you for this great ROM,

I noticed a little change in Android11, which drives me nuts.

Until Android10 I could put some large mapfiles to /storage/emulated/0/Android/data/... for my offline navigation app. Now I cant access this directory anymore (security reasons, as I read).

Also switch the navigation app to SD-Card didnt help, on SD-Card I can't access the Android/data folder too.

I dont like to root my device (and dont know the best way to do it, by the way).

Is the another way, to get write access to a specific app directory under /Android/data ?

( I tried adb shell nad could switch to the folder, but I had no write access. I this case my user name was 'shell')
[Galaxy A3, A5, A7, A8, A9 Original Android Develop] kurtn:
In recovery you have full access to all folders. Or you enable adb root in developer options and say to command line "adb root" "adb shell"
[Galaxy A3, A5, A7, A8, A9 Original Android Develop] blumentopf75:
Thats really amazing. Thank you.

Now I only need to get adb running with this ROM. Under Windows adb works, but under Ubuntu 20.04 it doesn't. Maybe adb ist too old in this linux distro, (but an S4mini with LOS Android 10 works like a charm).

Adding an udev-rule didn't help. MTP file-access works.
