[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Sanctum777:
When will this be stable?

Sorry i am impatient and excited?
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] SharkyBeAre:
I think that a ROM becomes stable when the biggest bugs are solved, and this ROM is still lacking a lot, it is better to let the developer work calmly.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Chockyv.:
Flash light is not working, and the last update on 10/30 is bad. Sometimes the ROM doesn't boot at all and even if it boots, on the second reboot it keeps showing showing the boot animation and stuck in it.

Dev, please fix those bugs as fast as you can....

Really excited to use this ROM on my j200g.

If you need an active tester, I am available.

Currently, Using the update of 10/21.

Good work :p
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] BlOoMind:
Yes, even I was stuck at the boot animation forever after I had to remove the battery and reinsert it in order to wake the phone. But now I think I have somewhat traced the issue being linked with rooting the device. I was flashing the ROM, GApps and Magisk (did this twice, same problem), but yesterday I flashed only ROM and GApps and so far the phone is running fine. I am keeping an eye on the uptime counter. What I intend to try later today is flash SuperSU for root instead of Magisk. I remember when I was on Nougat in my primary phone, I used SuperSU for root. Magisk became my go-to from Oreo. Time to switch back and give it a try.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Chockyv.:
Root option is already present in lineage rom. About phone>Developer option>root. Don't bother for that and still there's issue in flashing gapps, as they won't work well ..(issue)
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] TBM 13:
The flashlight is part of the camera, that's why it doesn't works.

I know about the boot problem. I already tried to do a lot of things to fix it. So far the only solution I found is to disable mobicore (which it's making the ril work) in the ramdisk.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] BlOoMind:
Oh lol maybe that's why 3rd party root was causing a clash. This is in fact LOS with AddonSU included. Nice.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Chockyv.:
Doesn't get clear. LOS+Magisk , LOS+GApps+Magisk worked perfectly up to some reboots and modules were also working but the problem is sometime it gets stuck in boot animation.

Though, there is no problem of frequent reboot like the updates before 10/30.

And i don't think flashing magisk created any problem.

I have been flashing all the updates since 10/15 :D

Hope it helps :good:
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] SharkyBeAre:
Any update?
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] TBM 13:
There wasn't a lot of progress this month. For now i only managed to fully fix the slow boot issue, which was caused by the StartSensorThre crash.

First boot takes like ~2 minutes. A normal boot takes like ~1 minute.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] mitrajahany:
This is incredible. Thank you for all the time you're spending on this project, It's much appreciated.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] SharkyBeAre:
I hope you can fix the bug and get that sensor do not cause it, good luck, and you really appreciate all your effort in this project. Thanks for keeping the J2 alive.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] SharkyBeAre:
I imagine that the boot bug fix will take a long time and will create new Bugs.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] TBM 13:
If you read my previoud comment you will notice that i already fixed it when i wrote it.

And no, it doesn't creates new bugs.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Zedeon_:
The boot bug and the random reboot bug isn't fixed at all and still has too many connectivity issues

but still a great rom.

Looking forward to the future fixes for this bugs hehe.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] TBM 13:
I know about these issues.

The boot issue was already fixed but i didn't update the rom yet.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Zedeon_:
Hey. Just found out that YouTube app doesn't work on this ROM. I already tried YouTube Vanced (Rooted, Non Rooted and also the Magisk one) and also tried the stock YouTube app and it doesn't seem to load at all while if I try to go on the website version. It works just fine. Hoping that you fix this.:):o
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] TBM 13:
I noticed that bug, but I don't know why it happens.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] mitrajahany:
hi i was wondering if you know when will the fixed boot version gonna be released, that's all i need. i literally dreamed about it last night. thanks mate.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] TBM 13:
I was waiting for something else to be fixed, but since the development is very inactive this month, I will probably release it today or tomorrow.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Zedeon_:
I'll wait for the release this day. I really need it fixed even if it's just the random reboot and boot bug hehe. I just need it to be like that.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Zedeon_:
Also, I forgot to mention this but I came upon a connectivity bug/issue where the phone can't detect any of my SIM Cards at all. But still hopin for future fixes.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Zedeon_:
One more thing, it can't handle 3D Games like Mobile Legends:Bang Bang and Adventure Quest 3D. It just crashes when the game starts or when it starts to load the texture. I think it's a kernel issue. But still a nice rom.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] TBM 13:
New update available for download. Changelog:

Fixed startsensorthre crash, which was causing the long boot issue - TBM13

The J200BT model is now recognized - TBM13
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] TBM 13:
I'll take a look once i can.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Zedeon_:
So my device will show up as SM-J200BT now? And also can you overclock the clockspeed of both cpu and gpu. I think it will help a bit when talking about performance.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Zedeon_:
Also can you make the camera work for J200BT? It would be awesome hehe
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] SharkyBeAre:
At the moment it does not work for any model, when it is corrected it will not only be for one model, but for everyone.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] TBM 13:
If your device model is J200BT, yes.

I'm not interested in overclocking at the moment.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Smorya:
Please bring its stable and safe version for samsung j200g. I am waiting for a long time for this rom. Please bring it fast.

USB Tethering & Portable WiFi Hotspot is not working

USB Tethering & Portable WiFi Hotspot is not working (when mobile data turned on)
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] SharkyBeAre:
development has stopped?
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] TBM 13:
No, it's progressing slowly.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] TBM 13:
Hey there, happy new year!

New update coming soon, with both cameras working.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] SharkyBeAre:
Happy new year!!! TBM, We are attentive to the update, I hope and the remaining bugs are relatively easy to solve
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] TBM 13:
I hope that too.

Just tested GPS and it's working fine, not sure if it was broken at some point.

About the YouTube not loading issue, it's probably related to the codecs. I'm trying to fix it. Video recording doesn't work probably because of the same issue.

Performance issues may be related to the fact that we don't have a swap partition. Didn't have luck fixing it yet.

I still didn't test the WiFi hotspot. I would really appreciate if anyone can do it for me and send the logs.

I don't have any idea yet of why the audio stops working. People didn't tell me anything about it, so I'm wondering if it only happens on the J200M.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] SharkyBeAre:
maybe the GPS thing was fixed at the time of correcting another bug and you didn't realize, Lol

I hope you can find the solution, slow, but sure

About the hotspot, I'm not sure, I will try to test it and how can I send you the log, and how is it activated?

It can't be your phone? It may have physical damage that causes the audio to stop, now that you say the camera is already working, I will install the rom again since I find it relatively stable

Thanks for the development to this phone, TBM :laugh:

---------- Post added at 12:44 AM ---------- Previous post was at 12:41 AM ----------

Edit:

YouTube Vanced allows you to change the codec for the application, I'm not sure if that could be a solution at the moment.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] TBM 13:
Don't worry, i just fixed USB Tethering and maybe WiFi Hotspot too.

I don't think so. I never dropped this phone. Even the screen is in perfect conditions.

Also, the problem happens sometimes after the phone enters/exits sleep mode. It's very weird.

Well, if you go to YouTube.com on the browser seems like it works.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] TBM 13:
I just tested Mobile Legends: Bang Bang in the latest experimental version of LOS 14.1 and it worked fine.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] SharkyBeAre:
Do you know how the ambient screen is enabled?
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Zedeon_:
mine crashes when in ranked/classic

---------- Post added at 12:29 PM ---------- Previous post was at 12:02 PM ----------

is the camera fixed now??
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] TBM 13:
I will take a look to it later.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] TBM 13:
Oh, i thought you said when the game starts.

Next time it crashes, send the logs.

Yes. I will upload the new version soon.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] SharkyBeAre:
Another question, I have tried the rom a few times, but I have the doubt if when I get updates I can install it over an old version.I say this because of the fact that I had phones that, when installing a new update, creates a bootloop and the phone never turns on. or directly I have to do a clean installation again without operating system.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] TBM 13:
I always recommend to do a clean installation, but you could try to backup data from TWRP, flash the new version, and then restore data.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] TBM 13:
If you mean the ambient display, you can enable it via Settings -> Display -> Ambient display
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] SharkyBeAre:
the rom can now be called "pre-stable" since most bugs were corrected that made it almost unusable
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] TBM 13:
Once i release the new update i will change the ROM status from Alpha to Beta
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Zedeon_:
Will just try it again after you release the update. I'm using a different rom right now.

Hoping for the working camera update
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Manav Harsana:
Nice rom!!!:)
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] SharkyBeAre:
waiting for the new update XD
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] TBM 13:

Now that less bugs are remaining, the status of this project can be considered BETA instead of ALPHA.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] TBM 13:
Please tell me if you find a bug that isn't in the bugs list :)
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] TBM 13:
I downloaded the YouTube app and it loaded this time :confused:

Update: Seems like the YouTube app works fine now.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] SharkyBeAre:
Hi! I have found a bug in WhatsApp's audios when you are recording them. When you start recording it is normal, but 3 seconds later (of voice in chats), the audio just cuts off. I mean, the microphone stops detecting sound, and then when you send it, you can only hear the 3 first seconds of it. That only happens in WhatsApp, I already tested with Instagram and the phone's default voice recorder (this bug doesn't appear), thanks!

I attach a .zip with audio inside that shows that only the first 3 seconds are heard and the others are not :(

I don't know if the audio cut on WhatsApp is for the codecs, but if I can help you send a log, I would
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] SharkyBeAre:
And I confirm that YouTube really works correctly, it does not present any problem, and as for what the audio stops working also happened to me, but the phone was not idle

In my case the Gapps do not generate a problem in performance and the phone is even more fluid than ExCustom (in my opinion)
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] SharkyBeAre:
TBM, the long's vibration bug and the resetting that stays in bootloop keeps showing up, but I'm thinking (a lot) about that the issue is coming from the vibration's motor, there must be something wrong with it, because the last post I did regarding to the bootloop was due to the same issue. And I say this because when the phone was locked I received several WhatsApp notifications at the same time, and after a notification's vibration the phone got stuck vibrating until resetting in bootloop. I must also add that the option to control the vibration is not included, or doesn't show up. I think that is the problem with the resetting and the long vibration before turning off. There's something wrong with the vibration's motor when the screen is locked. Thanks!

I add that certain applications have a very high vibration intensity, and that's why I think all of the above happens when the phone is locked.

---------- Post added at 06:35 AM ---------- Previous post was at 05:42 AM ----------

Hello, never mind my last posts regarding to the resetting issue, I found out that it happened because the ambient display is broken and doesn't work.

I add that the audio stops working for something similar to that of the previous posts, when many notifications are received at once. and in my case the bug still persists that sometimes the phone does not turn on
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] TBM 13:
Thanks for the report, I will check the microphone.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] TBM 13:
Mmm, I will take a look to the ambient display.

We still don't have a hint of why and when the audio stops working, so it's currently impossible to fix.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] SharkyBeAre:
Is it impossible that the frequency of the cpu is what causes the audio to stop working when the phone has the screen locked?

I say this because there was a ROM for another phone that was the same, and everything was related to the CPU frequency
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] TBM 13:
I have no idea.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] SharkyBeAre:
I have found very small bugs with Spotify, two specifically, one is that album covers are sometimes cut and canvases do not work. they don't affect anything, but I don't know if I can something similar happen in other music playback applications.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Zedeon_:
Camera doesn't work for me hehe
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] SharkyBeAre:
What model of J2 do you have?
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Zedeon_:
SM-J200BT or J2 DTV
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] SharkyBeAre:
I am not completely sure if this ROM is compatible for the version you have, because it is practically based on the j200 (G - GU - F - M) models. I think you are very lucky that this ROM can boot and can work, if I remember your phone has the same processor as the "J200H" try to check
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] SharkyBeAre:
Lol, Subtratum works correctly and does not generate bootloops or crashes in applications
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Zedeon_:
this has the same chipset with G,GU,F and M
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Prove N.:
Just to be clear, If the processor isn't compatible, it wouldn't be able to even boot (soft-brick essentially), let alone just the bugs.

1. J200H has 2 versions, Exynos and Spreadtrum. E: I havent found any Exynos J200H so I'll not say this.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] TBM 13:
Front camera or both?
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] TBM 13:
The J200BT model has an Exynos 3475 chipset, which means that it's supported.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Zedeon_:
Both doesn't work. Is there any quick fix for this?
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] TBM 13:
They should work. Could you send a log?
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Zedeon_:
How can I send a log? I don't know how lol.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Jaja26000:
Multiple random reboot

Hi everybody,

There are random reboots on J200F, with roots, activable on developpement, I've installed hibernation manager and activate the CPU hibernation and for now after test there arent random reboots, I think the CPU needs to be lowered.

Good work developpers, this ROM is very stable, smoothy and beautiful !!
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] TBM 13:
I can confirm what [MENTION=9459664]SharkyBeAre[/MENTION] said; ambient display is broken and it crashes the whole system, so make sure to disable it.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] SharkyBeAre:
and the bug that WhatsApp only records the first 3 seconds ?, or does it only happen to me?
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] techdisc90:
I Found Some New Bugs

random restarts

4g network is not working completely (maybe only for me)

audio stops working and to fix this restart the phone

otherwise this rom is very stable,beautiful,and best i ever tried

thanks to (hard working) developers:good::good:::)
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Jaja26000:
Bug whatsapp records

No, the bug of whatsapp records happens to me too.

But, if you're launch whatsapp, you can record audio whatever you want and if you want send a new audio you can records 3 sec maximum. You must relaunch whatsapp for send an audio + 3sec.

I have an another bug if I call somebody, with a normal call or whatsapp, there isn't sound, I must shutdown my phone for calls working.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] TBM 13:
Can't test WhatsApp on the J2, but I will take a look to the microphone itself
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] TBM 13:
Does those random restarts include long vibrations? If yes, try to disable ambient display in settings.

We are aware of the 4G and the audio issue.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Jaja26000:
Yes, random restarts include long vibration, I'll try to disable ambient display and I'll tell you.

Thank you and good work
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] SharkyBeAre:
relaunch WhatsApp? I'll try. and the last bug is that the audio stops working, calls and video calls work correctly for me

---------- Post added at 08:25 PM ---------- Previous post was at 08:19 PM ----------

By the way, I am realizing that the audio stops working when the phone stops playing sounds for a long time when it is used normally and then the screen locks.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Jaja26000:
Yes, there is a problem with sounds, like

SharkyBeAre said. I havent problem with random restart now.:good:
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] rosivan3:
Restarts

The Mobile Phone restarts, turns on and after a while restarts.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] SharkyBeAre:
Disable the ambient display, that generates random reboots
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] SharkyBeAre:
I am pleasantly surprised by this ROM, by its performance, its speed when turning on the phone and the space that leaves free newly installed, better ROM than any other based on TouchWiz.

something strange that I noticed but that I think is a bug already discovered is the issue of volume, some things in the system sound good, with a high volume, instead others sound very low, and so it happens with some YouTube videos.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Zedeon_:
Oh one more thing. I'm experiencing issues regarding the battery. Took 14hrs just to charge phone from 15% to 100%
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] TBM 13:
We are aware of battery charging issues. You can charge it on TWRP for now (if you want to)
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] TBM 13:
I need to tweak the volume levels. Will do it for the next update
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] SharkyBeAre:
I found another interesting bug. If you activate the "Protected applications" after configuring and using it, it crashes by closing all applications and restarting the phone, the system partition is damaged causing the phone to not turn on anymore. And upon entering TWRP it is recognized as a damaged partition And it cannot be fixed, it only remains to format the partition and reinstall LOS 14.1.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] TBM 13:
Sorry for the lack of updates. This is what happened these days:

LineageOS 14.1:

Fixed video recording

LineageOS 15.1:

Booted! (yeah, oreo booted).

Thanks to imranpopz for the kernel binder update.

I won't release it yet until it gets a little bit more stable. Currently critical things like WiFi and RIL aren't working.

LOS 15.1 sources are available on GitHub.

Note: This doesn't mean that i will stop working on LineageOS 14.1. Oreo shares some bugs with Nougat, like the audio and the microphone issue.

What about LineageOS 16.0? Now that Oreo booted, it should be possible to also boot Pie. Anyway, i prefer to get at least a semi-stable Oreo first.

What about Treble? As Bengris32 says, it may be possible by doing some modifications to the device partitions. But this isn't for everyone, as someone could mess-up the partitions. edit: actually, the partitions modifications can be done with a TWRP Flashable ZIP
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] SharkyBeAre:
oh man, really? did you get to boot Android 8.1? I will continue to use Lineage 14.1, but if you can maintain the development and bugs you can correct them at the time in LOS 15.1, I will go to that version.

I hope and you can keep both ROMs, but if you can stabilize LOS 15.1 I will go to that version

By the way, the Treble project can be achieved? I hope and you can get it, although I never understood perfectly what it is
