Thanks for your work, Flashed the ROM and it is working fine.

Screen recorder is not working
WiFi and bluetooth are working.
Can't say anything about Volte but I can recieve calls and messages on Jio sim without any problem.

I will report bugs if I find any.

The problem with VoLTE is that outgoing calls are broken when your operator enforces VoLTE.

Flashed everthing is working smoothly(2x faster than RR rom)
Only problem with setting>system = setting crashes
Thanks dev for the awesome rom.

Doesn't happen on my device... Does it happen after a reboot? Do you have GApps installed? If yes, which package is it? There could be many reasons, logs would be helpful.

Strange, I don't have this issue... Also, did you dirty flash this from RR? If you did a dirty flash from RR, then you probably need to do a clean flash...
Edit:Logs would be helpful for the dev to figure out what's causing it...
Edit 2: Does mtp work for you?

Yes i did dirty flash from RR.
Okey i will try clean flash tomorrow.
Yes mtp works for me

 

[Hausemaster]

Yes i did dirty flash from RR.

Then it might most likely be the reason for your described crash

Yes mtp works for me

Does copy-paste, creation and deletion of files and folders work too?
As you can see, I'm able to access the system section without crashes, so, please clean flash and then report back with the results...

After clean flash setting working properly,
Thanks
And mtp fully functional for me, delete,copy,cut etc everything working.

Edit( sorry for late info.) : before clean flash , i checked settings in guest mode everything working properly in crdroid. May be my data from RR rom causing problem in crdroid rom settings.

Great! Also, just remember that you can dirty flash an OS if and only if the OSes are the same, for example you can dirty flash a newer version of RR on an existing installation of RR, but dirty flashing a different rom can cause things to break, so, just keep this in mind during dirty flashing...

Just Amazing !!! Installed crDroid after trying LOS 18.1 and have no words for the speed & Performance of this rom highly optimized and customizable far better than RR (I also have tried ur RR rom) but faced some issues comparing with Stock Rom and I know I have to accept those issues,
* My tab's voice, lol (DOLBY Atmos) (is there any way to get it back ???)
* Notification Light not working in this Rom , donno why but it was working in all other Roms (RR, LOS 16, LOS 17, LOS 18)
* Green Thumbnails for Videos, difficult to Identify Videos in Gallery
* Unable to to post videos on INSTAGRAM
* Dim Imaging while using camera other than Default mode (dim in portrait and Video mode,, not sure if it was in other tried Roms)
**** Major Issue is restarting of Apps Sessions on every task switch (happens in all tried roms)

and more will be discovered later in the future,, Not ALL the issues described above related to this Rom Just Expressing my Experience of using ROMS for this Device for new comers


At the END @adazem009 thanks for this Highly Optimized Rom,, tbh Its very faaaaast

Dolby should be possible to add to the ROM, but I think I should extract it from the stock ROM first. I'm not sure if it's device-specific.

For sound(voice ) you should go with viper4android.
All los based roms have green thumbnail issue according to my experiences.
And restarting of apps on task switch is due to low memory(setting>system>developer>memory only 400-500mb free for task other than system):-solution may be help you :- try to use less customization , clean ram and remove unnecessary tasks , kill background services and tasks.
And yes notification light not working except in charging case.

If u can then plzz go for it ,, its the major issue ,,, but I dont think it will work ,, I have tried lots of time to install dolby by magisk but it didnt work at all.

I have tried v4u before (in RR and Los 17) but its nothing in comparison with Dolby sound (high sound)
nd Notification light is not working in all condition even while charging (but was working in RR and LOS before),, may be something went wrong while installing crD by myself !!

Try viper4android, it works nicely, and also, implementation of Dolby into the rom itself and installing it via magisk is completely different...
