Yes, I'm currently using the Stock ROM and mobile data works flawlessly.

No, there's no problem with my SIM Card Provider and at the time of setting up your ROM, I had a data plan active.

No, my phone variant only has a single SIM slot.

BTW, as I told you previously that there might be a problem that could have occurred during the flashing process that could have messed something up. So I'll try to reflash your ROM again ASAP when I get the time to do so and I'll inform you if the problem still persisted or not. Cheers!😄
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Lendigo4:
So I just reflashed the ROM and yes, the problem still exists. Mobile Data still didn't work for me. Calling someone is totally fine (if we ignore the problem of the sound coming from the rear speaker instead of the earpiece speaker). So. I guess this problem may occur on the device model I own (SM-G532M) but idk, you know better lol. I've also attached some screenshots for your convenience. Cheers! :D
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Prove N.:
or maybe it's the "single SIM" that I didn't account for... I've only tested for dual SIM devices.

e: more questions since idk how single SIM device works with this ROM

1. Is your SIM selected in Cellular Data section (Settings -> SIM cards -> Cellular Data), like in the pic?

2. Have you rebooted at least once?

3. Do you know how to take logs? (logcat, dmesg)

sorry for the inconvenience~
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Mhossein12:
Hello, my problem is that the phone's touch screen gets stuck for a few seconds (about 20 seconds).
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Mhossein12:
And if there is Lineage 15, leave it even if it has a bug, thank you brother🙏🙏
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] atatero:
Mine is a sm-g532m. Isn't like the pic.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] atatero:
I don't know how to take logs. But i want to help.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Lendigo4:
1. Well the screenshot you attached doesn't look familiar as I've never seen those options before. Though I can't confirm as I'm not using this ROM currently as it's not that daily-driver able yet. Maybe these options don't show up on Single SIM models idk lol. But I did however looked thoroughly but couldn't see such options anywhere.

2. Yes, I rebooted multiple times just to be sure but nothing worked, unfortunately.

3. I apologize but I don't know how to take logs. Maybe I can look up how to take logs on the internet if that would help or if you want, you can tell me how to take them for your own convenience. But I'll try by doing some research.

And it's totally fine, there's no need to be sorry for it. You're creating this ROM, and that's more than enough. And it's also just in the beta stages so yeah, problems can occur. Only if I knew about ROMs and stuff I would love to help you but nvm, I'm wayyy too noob for such things. But still, keep it up!😄

Edit 1: Does this article contain what needs to take logs? I do see "logcat" and "dmesg", but I just wanted to be sure.

Edit 2: I did what the article told me to do and hopefully I've done it right as it was my first attempt lol. I couldn't attach the logs here for some reason as XDA isn't allowing me to idk so here (Google Drive) is the link to them.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Lendigo4:
BTW just out of curiosity, I flashed the previous update of this ROM just to be sure it wasn't my SIM Carrier's problem but no, mobile data worked flawlessly with full LTE speed LOL. Everything that was supposed to work in that update did work as intended.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Prove N.:
2022-02-16 one? Now that's concerning. I'm looking into it~

[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Lendigo4:
Correct! And thank you in advance! :D
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Prove N.:
can you test this one, I (kinda mindlessly) changed `persist.radio.multisim.config` incorrectly which might have made data not work on single SIM. This build reverts that back to the 2022-02-16 one.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Lendigo4:
Sure, I'll test it and will report to you asap. 👍😄👍

Sorry to bother you, is the headphone jack working? or is the problem still there?

I really want to use this rom but I can't because of headjack problem
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Akbar KanColle:
Well but if you put on some 2 for single SIM it works, so I'm lazy to flash hotfix :3,
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Lendigo4:
Unfortunately no, it still doesn't work. But the Bluetooth works completely fine.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] nisheri-ascar:
Hello, I have this weird issue where after flashing it boots fine, but after next reboot it's stuck on boot (specifically in the yellow text so I assume this is some sort of relation to the kernel), is there anything I can do to pinpoint the problem?
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Prove N.:
I would like some more info

1. Was this on latest version of Lineage?

2. What was the yellow text?

3. Did you make any modifications?

In the meantime you can try the last known good version: https://github.com/almondnguyen/and...age-14.1-20230623-UNOFFICIAL-grandppltedx.zip
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Akbar KanColle:
bro, can you build go edition.... Just asking
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Akbar KanColle:
Nah I face too, if phone out of battery it will stuck probably kernel issue, my fix backup boot.img and restore it fixed

EDIT:IS LATEST VERSION
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] nisheri-ascar:
• Yep, this is on latest version (20230707)

• Sorry for little bit misunderstanding but i meant the `KERNEL IS NOT SEANDROID ENFORCING` part during boot

• I only installed magisk, but it occurs without magisk installed

I finally pinpointed the issue, to reproduce:

1. Turn off the phone, completely shutdown

2. Plug in the charger

3. The charging animation doesnt show

Rebooting doesn't help, it's stuck

Haven't tested previous good version, internet is kinda bad atm
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] nisheri-ascar:
Wheew good to know I'm not the only one, I thought I permadestroyed my phone from booting pmos :D

[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] white_sparrow:
Hi guys, great rom. By the way, I couldn't update the rom via OTA update. In fact, i downloaded and installed the rom via the update menu. But after the final rebooting, The OS version was the same as before the update. The last update file was there even as a newly released update for the rom. i tried this several times. After that, I downloaded the zip file and installed it directly from the TWRP. It worked.

I am gratefully waiting for new updates.😘
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] TheProGadgetR.O.D:
how am i supposed to update to version 07/07 (? the os lineage OTA doesn't lead anywhere and installs the same rom from the past update, please i want answers!
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Prove N.:
It was temporary to fix the 0707 kernel bug that many complained about.

Hey, bro! I had installed ROM to my Samsung device. It is 20230707. I have some questions:

1. Can the screen recorder recorde system/application sounds?

2. Why this device Can't use Google Voice Match?

3. Sometimes the screen is error that I can't use it(unable to touch, touch failure)

4. Can you add Quick setting keys for screen recording？

5. I use my USB cable to charge my phone, but the lock screen says "low speed charge". How can I fix it?
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Prove N.:
1. yes

2. I don't use this feature so idk. Maybe Android too low, or device doesn't support it.

3. Please report back if touch bugs happen on earlier version (e.g. 2023-06-23). Too little info to confirm that it's software related.

4. Lineage's Recorder app doesn't have a QS tile, so 3rd party app is your best bet.

5. It's the weird charging current detection from kernel that I can't really fix, but it is kinda harmless.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Equinoxes:
the rom is getting better and better, i am using the pre-release version. I am surprised about the performance, it is smooth and responsive, no lag, battery improvement and mobile data and Bluetooth works fine (i used only one sim), A BIG THANKS TO THE DEVS =). not to tell, however playing Minecraft in this rom is pretty much much faster than the stock one!!
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] t0pu:
I tried the pre-released version 14.1-20230707, and it's fantastic: faster, and most of the functions work. The front-speaker support for phone calls not works... But, many thanks to the ROM developers.

Okay so i installed it on my phone and i tried to install OpenGapps with it. It succeded but while configuring it (after clicking "setup as a new phone") it wqs just spinning and got stuck for over 2 hours and it eventually turned off. Now i'm gonna try to reinstall it with LiteGapps, either that or i can try setting it up first then going to TWRP again and then installing Gapps.

[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Prove N.:
Attachments included. A ~20s logcat after full-boot.

(please note that I've used ROM for the day, so maybe I skipped some details, I'll get back with clean logs later; also, zip because size limit)

Oh, did not notice that. Apparently I kept my battery so good LOL.

I know you are (and probably everyone is) so patient right now.

Please understand that

1. This is the very first *Samsung phone with MTK chipset.

2. This is also the very first device I made ROM with. (in fact, i'm only over 1 year into ROM development _and probably half of that time i was busy with school_ )

So, XDA's rule of thumb: please don't ask for ETA

Screen Record please? (Recorder app works)

Would love if any logs are available.

oh, forget to answer. RIL of course. Media/OMX can be fixed with Wileyfox Spark blobs (porridge on GitHub), but i'll try using native blobs 'till the end.

Would love for any help. Just something to note: don't even think of MTK RIL, its blobs or its implementation. This is Samsung RIL.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Prove N.:
Worth looking into!

----------------------------------------------------------------------

yep. Why is this your concern?

to be fair, most devices' custom ROMs (including this one) use software Gatekeeper/Keystore, so can expect just a few bugs)

E1: nope, you CAN set it, but once set, you CANNOT change it. (just did a double check~)

----------------------------------------------------------------------

Fully copied from LineageOS/Telephony: https://lineageos.org/engineering/Telephony/

E2: So idk, maybe I will try including it and hope nothing conflicts with each others.

Probably because of RIL, not the cause of it not working

Probably open-source code problems. The (e2:) *TelephonyProvider folder exists in this ROM but not in stock MM ROM.

This has references to CodeAurora. Seems like RIL reference code Qualcomm released. Will take more in-depth look into this
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Kesh2015:

Camera: no HAL, but the front cam ,a s5k5e3yx, is open-source (?) according to some Spreadtrum device tree, so *maybe* is fixable.

Rear cam, a Sony IMX 219, require HAL (google for its definition) no doubt. the only HALs available are from another devices with Qcom chipset unfortunately.

Good news. Just got an answer about our problem with RIL.

Here's what he wrote:

You need to edit zImage, the fact is that when you start cm 14.1, native support for file system drivers (anyway, etc.) falls off on our device. But in general, she is almost working.
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Prove N.:
Can you link to the reply? I am building with kernel source, not prebuilt one (hence the zImage), so patch can be applied directly to the kernel source if needed.

` native support for file system drivers (anyway, etc.) falls off `

what do you mean by this? Possibly RIL driver failure in kernel? Probably will look into this, though I'm a total noob in kernel mods.

(and I'm positive this is not the case, because with other devices I don't see any of driver mods for RIL)
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Sub_Zero2:
There might be a kernel configuration for this.

Tip: "make menuconfig" (but you probably knew this allready)
[Samsung Galaxy J2 ROMs, Kernels, Recoveries, & Oth] Prove N.:
There is, in defconfig file

CONFIG_MTK_SRIL_SUPPORT=y

which is the same S-RIL defined in ueventd.mt6735.rc .

Kernel menuconfig search returns this

Symbol: MTK_SRIL_SUPPORT [=n] │
│ Type : boolean │
│ Prompt: MTK support S-RIL │
│ Location: │
│ -> Device Drivers │
│ -> Misc devices │
│ (1) -> MediaTek Properitary Configuration (MEDIATEK_SOLUTION [=n]) │
│ Defined at drivers/misc/mediatek/eccci/Kconfig:130 │
│ Depends on: MEDIATEK_SOLUTION [=n] │
│

but, i can do, and did nothing with this. As in Exynos S7 (its software in some way is very similar to J2 Prime), no RIL drivers or stuffs were defined in defconfig, so my bet is that this is just MTK implementation and nothing to do with Samsung RIL.

erm.... I probably should say that I have way less free time now that school is coming (my excuse for the total mess of the first 2 weeks of school too lol)
