LineageOS 19.1 for SM-T580 (gtaxlwifi) and SM-P580 (gtanotexlwifi)

[Origin_X]

New option for disabling the taskbar

A new option for disabling the widely disliked taskbar has been added by the Lineage team.
Along with that, I've fixed the problem where enabling the "Enable on-screen nav bar" option at Settings -> System -> Buttons disabled touchscreen input entirely, which makes that new option for disabling the taskbar usable.

Now, to disable the taskbar, it's unfortunately not very straightforward. The steps are as follows:

• Go to the Settings app, and in it, go to System -> Buttons.
• Enable the "Enable on-screen nav bar" option.
• Go back to the System section, and go to the Buttons section again.
• A new option, "Enable taskbar", should be there. Toggle it off. The taskbar should disappear and be replaced with an old-style navigation bar.

From there, to use the hardware keys with no navigation bar or taskbar, simply disable the "Enable on-screen nav bar" option.
Otherwise, that option can be kept enabled to have an "old-style" navbar, with input from touchkeys being ignored, and with no taskbar. Different methods of navigation can be selected at Settings -> System -> Gestures -> System navigation.

Had some issues with getting the taskbar disabled; though not sure if this is due to Pixel Launcher being installed from my gapps of choice (omni). I performed the above but seemed like the taskbar was just stuck on and even persisted through a reboot when all was disabled. Did some digging and found a fix for myself in feature flags.

Here's what I did:

1. Enabled Developer Options
   • Go Settings app -> About tablet -> tapped Build number 7 times.
2. Clicked Home button.
3. Long Press for the Pixel Launcher Popup Menu
   • Go Home Settings -> Developer Options -> Click Filter -> Type "taskbar"
4. Under Feature flags disable the following:
   • ENABLE_TASKBAR (Should be fine with disabling just this flag but I wanted it all off.)
   • ENABLE_TASKBAR_EDU
   • ENABLE_TASKBAR_POPUP_MENU
5. Click "Apply" in top right corner.

After the flags are refreshed taskbar was gone. So far, the taskbar has remained gone including after a reboot. Swapped to the launcher of choice (NOVA) and still no issues. Hope this can help someone else out with that pesky taskbar!

Beyond the initial taskbar issues, the ROM experience and operation itself are great. Happy to have some new life brought into this tablet for light on-the-go work, general other day-to-day tasks and even playing games via Moonlight and XBOX controller. I appreciate your hard work!

Every time i try to turn off the tablet with the rom, it reboots. With version 18.1 it doesn't happen to me. even with the one you just uploaded

Had this issue twice, but not on every shutdown.

Yes, I mean, from time to time. It happens more, when I've been using the tablet for a while. When I try to turn it off, it restarts, and the second time, I can turn it off, if I don't do anything else

How to update this safely?
Just flashing ROM and wipe cache/dalvik or do i need to reflash gapps and magisk?

Thanks!

//EDIT: using the april build currently

 

[Archaide]

Hi. For me it was just flashing and cache wipe.
I had to extract the bootimage, patch it with magisk and flash it to regain root but that's all. No gapps for me.

 

[Idah00]

Thanks for the new update, it worked like a charm with an install from TWRP and a cache/dalvik wipe, I can confirm that Dualshock 4 now works properly using bluetooth, I tested it on Retroarch and RVGL with great success, thanks again for this awesome ROM!

Hi all.
I either found a bug or something else is wrong.
As soon as i establish a connection to a VPN with OpenVPN i loose connectivity in every app. The only thing that works is a ping from termux to a lot of different urls. So the vpn itself is working. In bromite everything ended with a timeout. ( i can ping the same url with a few ms response) F-Droid does not refresh the repository, it says something like wifi configuration prevents refresh.
Is use this vpn on a few devices without any problems. (None of them with A12 without any google components. Might that be the culprit?)

That constellation worked on LOS 18.

Can someone help and have some advise please?
Best regards.

 

[omensight]

Does this work for gta3xl?

 

[zeb carter]

I flashed NikGapps-omni-arm64-12.1-20220421 (I need google photo as system app to avoid desync changes).
May I ask which gapps pack did you use?

I used Nik's Core GApps. Works quite well

Me too. I tried other method several times and worked:
Instead of using the side power button, pressing a few seconds and then clicking power off on the screen, try to slide down from the upper area, and press the power off button under the quick functions.

After a more extensive use of the device, I have a few issues to report to maybe improve the ROM in the future, somehow like others have already reported, the tablet will sometimes reboot instead of shutting down which can be problematic for battery saving, I have also encountered a bug with the keyboard, sometimes the keyboard will just freak out and not display at all or properly on certain specific situations rendering it unusable, one example was when I installed WhatsApp, I was prompted to enter the code I received with SMS and when I tapped the field to fill it the keyboard didn't display, installing another keyboard fro f droid solved the issue so this is likely a bug from the keyboard's software. That's all for now. Thanks again for working on this awesome ROM, I found this device in the trash and it feels like I got a brand new device with it ^^

edit: BTW has anyone managed to make the GPS work? I' m using microG and it doesn't work here, my phone uses microG and it works fine tho, so I'm unsure if its a me problem or a ROM problem...

Edit2: I also keep getting Intent filter verification service crashes, I don't know if I'm the only one facing this issue as well, dunno what exactly this service does and if it's related to microG or not, does anyone else have similar issues?

 

[TALUAtXDA]

First off for everyone, please don't keep reporting issues that are already known. I've already put the issue with normal rebooting when trying to power off or using an advanced rebooting option in my "known issues and workarounds" section of my original post. Reporting what's already known is effort for nothing and more email notifications for new posts reporting it.

At the moment, I don't have any information on it from logs from logcat from the few times I've been able to reproduce it right before a reboot, so I don't have anything on it. It's something I'm going to look into later when I have time.

I have also encountered a bug with the keyboard, sometimes the keyboard will just freak out and not display at all or properly on certain specific situations rendering it unusable, one example was when I installed WhatsApp, I was prompted to enter the code I received with SMS and when I tapped the field to fill it the keyboard didn't display, installing another keyboard fro f droid solved the issue so this is likely a bug from the keyboard's software.

Hmm, not so sure on the keyboard. All I know is that there was a faulty change that caused the keyboard to cover the entire screen with no keys displayed at all in most cases. I just reverted it. Maybe there's another faulty change? Hmmm...

That's all for now. Thanks again for working on this awesome ROM, I found this device in the trash and it feels like I got a brand new device with it ^^

You're very welcome. That's excellent.

edit: BTW has anyone managed to make the GPS work? I' m using microG and it doesn't work here, my phone uses microG and it works fine tho, so I'm unsure if its a me problem or a ROM problem...

GPS hardware works fine if you're using a WiFi-only variant device (and naturally doesn't if you're using an LTE variant device because of different GPS hardware, as I mention in my original post). Not sure if you're using an LTE variant device.
For network location, that's entirely setup-dependant.

Edit2: I also keep getting Intent filter verification service crashes, I don't know if I'm the only one facing this issue as well, dunno what exactly this service does and if it's related to microG or not, does anyone else have similar issues?

I'm using MicroG and I haven't got any such crashes. My best guess for a possible cause of them is an app that depends on Google apps, and uses that service, and isn't working properly and causing that service to crash somewhere along the line.

Hmm, not sure at all. I just tested a connection to my up-to-date OpenVPN server with the OpenVPN for Android and OpenVPN Connect apps, and there don't seem to be any problems here. Don't have any ideas, unfortunately.

WiFi only device here. Can confirm no GPS fix after 20 minutes waiting. No google components.

Yeah the keyboard problem is exactly as you described it, so probably another faulty change then...

I'll look into apps that depends on google apps to see if it solves my issue.

Thx for the feedback, I won't report problems that have already been reported

I just dirty flashed from LineageOS 18.1 on my gtaxlwifi, following your upgrade instructions, and everything is working perfectly except for one thing (it's also so much faster, love it)!

The only issue is that the hardware recents button doesn't seem to be working. It was working fine until I turned off the the taskbar, but now even turning it back on it still doesn't work. I enabled the software one as a workaround for now, but it's fairly annoying. Hardware home and back work fine.

EDIT: I worked around this temporarily by using Button Mapper and remapping the button to do... what it's supposed to . It's unfortunately fairly slow though.

EDIT 2: The "broadcast public intent" option in Button Mapper also seems to work...

Can confirm VPN is working. I wasn‘t in my homenetwork when the problem occured. As soon as i was in my usual environment VPN was working like a charm.
Sry if i caused trouble.

 

[sandervanzijl]

looking fpr a new rom for my t580. This seems good. Main problem is that my current bliss rom is getting a bit slow.
does this rom have better performance, or is the new android slower than older androids?

 

[Kat Jillianne]

Solved my previous issue regarding google play, it was due to a bad gapps package, core+addons works best.
Now another thing has been bugging me: is it normal that installing p850 (non cellular) build on a p585 (LTE) will causes IMEI to not appear under "about tablet" section?

 

[serik]

Hello, I'm having some issue with the Gapps and with the Rom itself. First I'm flashing the gapps with NikGapps selecting the SL category.
The installation seems to work. After I'm flashing the rom. And when I restart I don't have the Gapps on the system.
I tried to reinstall the Gapps and wipe cash. It is working now but I have a problem with the storage. When I go on the settings and storage it crashes. And I have an error that I don't have enough storage to install any update.
Is it coming from my Gapps I'm really struggling to find one version that works.

Thanks in advance
