Thanks! Battery life is trending better than the last build - maybe 3 days of idle compared to a little over 1. Still different than your 12.1 build which was more like 30 days. Edit: Just noticed I had left the new install at "WIFI Always On". I'll see if turning it off while asleep brings it to parity. Edit2: No, no change

Has somethings changed to make encryption less possible now than in 12.1? I've been running your builds with encryption on for a couple years and it's been fine, except that TWRP can't mount /data which I think blocks magisk, from installing; no big deal for me. (though incidentally, I found and then lost an xda thread for another MTK device where someone made the changes to a private TWRP branch to get it to decrypt /data. I wonder if those could be ported to this device?)
Sorry I missed this message. So you're saying decryption always worked? Well bruh.. I thought it was broken (or at least somebody reported that) so I disabled it as it's a big mess to fix up (in mediatek devices). I don't think I can port those changes to TWRP as that would require an update in the amonet thread.

Ok, sdcard issue is fixed, we'll do final tests and if all goes ok will release new version today.
If you want to try the "fix" flash this boot image using TWRP (to boot partition). If you use Hacked Fastboot flash it to boot_x.
I flashed the image and now syncthing can access the SD card. Read only, but this is an Android-Syncthing issue, nothing to do with the ROM

Many many thanks...

Good day,
Now we can use SD-card by applying boot_sdcard.img. Great, but I think battery drain increased. For checking I attached a log. Scenario is very simple, reboot, play a music on sdcard, then view a picture file in sdcard, finish. I hope the attached file might help solve the deep sleep issue.

Cheers,

Edit: The huge battery drain problem was occurred with AICP (my build with the latest device tree that enabled sdcard access). If this issue does not happen in LOS14.1, ignore this article. The log attached is with LOS14.1 to make it sure.

The tablet seems so much more responsive running 14.1 than on 12.1. Only thing is that a lot of the video apps for my country don't want to work. Would this be a magisk thing or a rom thing?

This seems to break compatibility with headunit emulator reloaded. The UI becomes hella slow compared to when running 12.1. Im assuming this is the vifeo decoding issue?

My understanding indicates NOT possible. I do not know the real reason but douglas is 64bit while karnak is 32 bit. You can check with requiered gapps. douglas needs arm64, karnak for arm. If compatibility were existent, we can try LOS16.0, even LOS17.1 that are now for karnak.

Cheers,

What's the point of this? Karnak already has LineageOS 14.1 and even 17.1
Sure, I'm on LineageOS 16 and its works kinda good with some bugs.
But sadly the Developer "Kaijones23" has no time or maybe? abandoned the Project..
And as I see you do a great job in updating for douglas.
I rather have a stable OS then the newest Version.

I just asked out of pure curiosity, because karnak/douglas have the same SOC and look very similar^^

And keep up you good work!:)

This is from my curiosity. Comparing douglas and karnak is very interesting (because I do not know the real difference at all). Douglas kernel configuration is in the folder arch/arm64/configs, this is quite natural. Surprisingly in the same folder there is karnak_defconfig. If this config file is in arc/arm/configs, I do not surprize. Karnak is said to be 32 bit, but the kernel is actually 64 bit??? Your answer is highly appreciated.

Cheers,

This is the reply to myself. I found that karnak's kernel is 64bit (at least LOS16.0). In the BoardConfig.mk of device tree, I found:

TARGET_KERNEL_ARCH:=arm64
TARGET_KERNEL_SOURCE:=kernel/amazon/karnak
TARGET_KERNEL_CONFIG := lineageos_karnak_defconfig

Karnak is more complicated than I thought.

One issue I've ran into with both the Lineageos 12 and 14 roms, is that PS4 controllers can be synced, but don't actually work. When a pair a ps4 controller with my phone, it's able to navigate menus, go back to the homescreen, etc., but with douglas it doesn't seem to be able to control anything and isn't detected in retroarch at all (the main reason I wanna use the PS4 controller with it). I don't know if this issue is specific to just PS4 controllers or more general as I don't have other controllers to test.

Also, I just want to thank you for all the work you've done on this device. Your lineage ports are the main thing that have made me like using my tablet.

I installed the ROM a few days ago and like it a lot! Only small issue is the not working Camera (eg. For zoom meetings) but its not that important.
I tried to monitor the CPU frequency to slow down the discharge in Standby. I just wonder, even if "Inware" and "Kernel Audiutor" shows in idle 1x 600mhz and under heavy load 4x 1300mhz, the Kernel Audiutor is Monitoring 94% of the time 1050mhz.
Is the Monitoring false or the shown frequencies?
(See booth pictures)

Oh you came to douglas, very nice. Camera issue is known and this is very tough, might be solved the very last. The current big issue is deep sleep. Someone reported douglas shows deep sleep if SD card is not used. Are you trying the latest (0105) ROM with SD card patch or not? My experiment shows even with SD patch applied and remove the SD card, douglas seems not sleep. If I know how to get logcat to show this situation, I immediately do it.

To make sure, under the LOS14.1 (latest and SD card patched, SD card removed), left the douglas more than 10 mins after reboot. The Adiutor shows this image:

I'm installing lineage-14.1-20210123-UNOFFICIAL-douglas.zip . Do I need to flash to sd-boot fix image? Also do I need to install magisk for root capability?
