I wasn't expecting a new version, I thought the last one would be the EOL because of Android 11. Impressive. I'd just like to know if it's possible to remove the low bar and/or the day information on top to get more space in the home screen, but that's not an issue at all. Thank you anyway

Hello,
Unfortunately you can only remove google search bar by using another launcher.
I personally use an open source Shade Launcher.

Device unauthorized in ADB

Hi all,
I previously used fOmney SmaliPatcher with this rom, but with the v6 I get an error message telling device is unauthorized. Trying directly with adb devices cmd I see my device tagged unauthorized. But on my phone usb debugging is set and adb is authorized in MagiSk.
Does anybody have an idea to solve this pb ?
Thanks in advance !
Hi all, the pb persists in v9, does anyone know how to fix this pb ?

Hi all,
In the v9, I don't find the built-in camer setting to store photos on SD card, is it normal ? No more a feature of the camera ?

I have tried rom v9 and observed that it drains the battery faster than v8. I had it installed for four days and went back to v8. I use pico gapps (from opengapps).
What is your experience with 9 versión?

Dear Developer and Readers,

Thanks for great work, again.
Very useful to use my phone much longer.

After installing newest V9 on I9505, without any problems, system prevents me from changing some settings. I need them, would be very good to check this.

F.e.:
Look at an app, settings.
"View over other apps" (or so ;).
Can not change this, system gives no option to turn it green, stays left.
Same with a few other system options.

Whats the problem?
Did a clean install with newest gapps.

I'll just say: Great work and Kudos to the JDCTeam!
My S4 got a whole new life !!

One question...
-How do I enable Signature Spoofing?
It seems to be disabled and I would need that for certain apps.

Here with i9505 and Optimized-LineageOS-17.1-V9.zip no problem.

Yes it's not enabled in the rom at the moment. I've asked the developer and he confirmed, that he could implement that feature. But we should not put too much pressure on him to implement it immediately (or at all), he's doing it in his free time.

If you'd like to have an instant solution, you could try to patch the rom yourself. But of course, that's not as easy as flashing a rom. Some research and work has to be done in order to enable signature spoofing. A good starting point seems to be the following link:
