Uh nice - thanks Valera! Any chance you can add your manifest? I would like to try building Android once myself.

Error flashed on screen on reboot

I am getting 'There's an internal problem with your device. Contact your manufacturer for detail.' error on every reboot. I've flashed the 'BL_T825XXU3CSH9_CL16530048_QB25611745_REV00_user_low_ship_MULTI_CERT.tar.md5' bootloader but still facing the issue.
See the screenshot for error message.

Camera is not working

Hi there,

do you have any intention to include palm rejection on Q?
It's the only missing feature on LOS...

Do custom ROMs have to have palm rejection added? It's not normal feature?

This would be good to know as I got this device to use the pen!

I notice that screen is very hard to wake up. I have to play all buttons in random combination to be able to bring up lock screen. Once it get unlocked, everything works find.

I did once get system UI locked error. I have to push all buttons to force it reboot.

 

[Stogie87]

So I tested this rom on my T820 Wifi and in my opinion it works pretty stable, except of some issues I recognised:

- Saving pictures does not work. The pictures I get are scrambled.
- sd cards in ntfs format not working
- Palm rejection is not working
- ed xposed causes boot into download mode
- screen wakup is sometimes slow
- Viper4Android is not working
- Speaker only working on one site (right)
- it's not possible to rename SD Card or uninstall any system app like mail-app via root
- Netflix is not working
- Not possible to activate a custom notification sound
- Adaway only working with systemless host activated in magisk
- trying to use miracast causes a complete crash of system ui and makes a reboot necessary
- digital wellbeing randomly fc if settings menu is open
- sometimes hardware buttons stuck and i have to wait 5 sec until I can use them again

Thanks for your work!

*update: On second build same issues and camera just force close, now

 

[ghostman256]

did anyone figure out how to get the camera to work. It takes pictures but to view them they all look scribble.

 

[MR2_Wei]

does this rom work with the T825Y?

Just try it. I think the specifications are the same like T825.

Just use gcam it 'll work

Not working on second build for me

 

[milleniumdroid]

Now for the *REAL* question, does this ROM cause graphical glitches when you run a 3D load and heat the processor up to 100c?! That was my experience various unofficial LOS16/RR based Pie builds. I get temps in the worst case up to 97c under extreme load on the stock OneUI ROM, but normally it is way LOWER. Could someone (with the performance level in the power settings set to max) test games like https://play.google.com/store/apps/details?id=com.PnA.Offroad and some heavier ones for an extended period of time, and maybe some benchmarks (AnTuTu, 3DMark, etc...) while watching the CPU temp and General SoC temp with a temp guage overlay (like the one in the paid option on DevCheck).

@Valera1978

Is there any chance, that you compile Havoc OS 3.0 for our Device?

Thanks in advance

I got it installed and booted but the rotate function isn't working, even when I open youtube and make it full screen it's doesn't rotate

Don't expect that anything on this rom will fixed soon.
Always the same with this dev. He releases a build with issues, then he ignores all issue reports and only releases sometimes a new build with security updates and nothing more. I wish a had wait a little bit and bought a tab s5e, because it seems to be the only new Samsung tab with fully working custom roms and palm rejection.

Better you use stock rom for tab s3.

I am getting 'There's an internal problem with your device. Contact your manufacturer for detail.' error on every reboot. I've flashed the 'BL_T825XXU3CSH9_CL16530048_QB25611745_REV00_user_low_ship_MULTI_CERT.tar.md5' bootloader but still facing the issue.
See the screenshot for error message.

same here

 

[bitelmaniaco]

There is something that I cannot understand. The users say that there are problems with the ROM but OP says there aren't...

Not sure if answered but I fixed this by:
Copying the complete line ro.vendor.build.fingerprint.................. from the /system/build.prop file.
Paste replacing the line ro.vendor.build.fingerprint.................. in the /vendor/build.prop file.
These files crosscheck each other looking for this line. The files must be from different builds.
