If you're having issues and want to submit a report (Logcat) please make sure you are reporting from the stock kernel, not a modified kernel. Modified kernels can break or fix, even improve things. It depends. I can't get a full clue of the issue when you're not running the original kernel.

My first issue is that Im not able to sign into playstore when or get past "Getting tablet ready" it always says "Couldnt connect" Not sure if its the rom or the gapps but im using opengapps. Anyway, thank you so much for the hard work that you have done with this rom. Extremely impressed. Thank you so much and looking forward to see more of your work.

Are you sure Wifi is connected?
If yes, try a different package of Gapps or try to restore a older backup (/data only) from a different ROM, if you have. Also be aware, that our tablets cannot connect to Routers with WPA3.
This will be fixed in one of the next builds.

Aye. Sometimes the Setup Wizard is causing troubles.

logcat and kernel logs. Also, the button for the camera is so low on the screen its cut off. I tried to make a phone call earlier, but it would just end the call immediately. Im able to get on the internet with 4G though

Hi. I´ve tested the Issues you mentioned.
The Camera App seems to be broken or has a wrong resolution. That´s nothing i can fix but i´ll report it to the devs. As a workaround install Open Camera. This App is working normal.
I tested phonecalls (in and out) with 4G and Edge. Both are working for me.
Maybe there´s an issue with your local provider. If the problem persists, i would suggest to dl ROM and Gapps again (maybe a file is corrupted), delete your ROM in TWRP + format /data and do a clean install of both, ROM and Gapps. Often this will fix those errors.
Your logcat is looking not too bad except a crash of firebase, what definetly could cause the trouble. But we´ll see it, if you´ve done a clean and fresh installation.

Hi, I got the SM-T531 tablet and I'm going to download this ROM and see how it behaves I will do all the possible tests I can do, to contribute. There's no way the 3g works right, just connections right?

Yes, unfortunately 3g isn't working at any ROM from 9 to 11.
Matteo is working on it but with no success so far.

Hi @crazydrive22 . I'll take the opportunity and ask you a question of mine. I'm having trouble flashing any SM-T531 compatible roms. I will list the steps I followed.
1 - Flasing twrp with heimdall. At first I tried here: https://twrp.me/samsung/samsunggalaxytab4101.html but ta off the link there.
I downloaded it here on the XDA forum: https://forum.xda-developers.com/t/recovery-3-5-2_9-unified-matisse-millet-twrp-recovery.4019831/ ;
2 - full wipe and format;
3 - Flashing this rom (with or without gapps) Resulting: Loop in Samsung logo or should I wait too long?
Thanks for working.

Hi.
First boot can take a lot of time. If it's not booting i would suggest to flash Stock 5.0.2 and start again from scratch. It's nescessary to had 5.0.2 installed once to make sure, that the Bootloader is updated. The Bootloader from KitKat (4.x) is not working with LineageOS 9 or newer and it's forks like crDroid or Cypher. The TWRP from Matteo is good, it's the lastest one and working well. But i can't tell you anything about Heimdall. I'm using Odin only to flash Stock or TWRP.

Thanks for the answer, it must be the 4.4.x bootloader, I didn't even ask if I had the 5.x.x one, I'm flashing the 5.0.2 About haimdall. It's wonderful, a point that can be negative is that the process is more manual, you must select each file for its respective partition, the good thing is that with it you can capture the pit file, it is very rare for an error to occur except if there is a problem on the PC or cable. It works on Linux and Windows and Mac OS X. I will return with news.

This is working amazing on my SM-T530NU, far better than whatever Nook bloat that was running before.

Installed and tested in matisselte, very good rom, very fluid. Everything works perfectly,
I will continue using this rom, very happy with how it works.
I hope you continue with the updates. Great job
