Hi guys do you know if it is possible to install microg on it ? Right now i'm on Slimlp but i think android 5 is a bit too old for thirdy-part-app compatibility,some of them can't really work
Hi,

Unfortunately I haven't included the MicroG patch into this ROM. I'll include it in the next update.

Regards.

Hi thank you for all your hard work,i will really appreciate to enable the microg support in the next build without the need using Xposed or Magisk. So I'll take an eye on the next release (are there OTAs ?) and thank you again

Edit : Oh i have another question,is the HW acceleration for 1080p videos broken on all ROMS (including Slimlp,LOS12.1,14.1) or just in this one ?

  • Are you using douglas (2017 version) or giza (2016 version)?
  • So, exFat SD cards never worked in lineage-14.1 either?
  • I thought WiFi drops were solved long time ago (when I switched to prebuilt MTK WiFi HAL), are you using 5GHz networks?
  • Oh sorry, should have mentioned, douglas (2017)
  • exFat did not work on one of the first few builds of lineage-14.1. But it worked later after an update, don't remember which. I think I had posted a comment in that thread too at the time, but I think you had already patched it by the next update, let me go look that up.
  • Hmm. I am using 5GHz. I just tried rebooting my modem and routers (should have tried this in the first place). I still have some drops, but downloading is much better, I could install apps this time.
 
Quick question, what file system does this rom format your SD card to? iirc it uses FAT32. I remember having trouble copying a video file greater than 4GB in the past. I just reverted back to FireOS last night, because I wanted to check something, and noticed FireOS uses exFAT for SD cards.

I remember the rom not recognizing my old SD card because that was exFAT, so i formatted it from the storage settings tab, and it formatted to FAT32.
This was July 7th 2021. So one of the roms before that. Because I went back to lineage after this comment and exFat worked. So you had already fixed that, I just didn't know it. I may have been using a January build of lineage-14 when I encountered this initially I guess.


But now exFat is not working for me on the latest lineage-15 build.

HW acceleration only works in Android 5.1 based ROMs (LOS 12.1 and SlimLP).

Alright, thanks for the information. I guess I'll need to update the exFat kernel driver.

Anyone else having difficulty charging sometimes? Sometimes it charges fine, other times it still drops when plugged in (especially when it's below 50%).

Yes, big time. We try everything: different cables, chargers, positions for the tablet. I even took it apart and tried this fix:

Improved things a bit but it's still finicky. Seems like a known issue with these tablets. (Nothing to do with this awesome custom rom, of course, as I observed this issue on the old FireOS stock rom too.)

Just installed this to replace the older SlimOS that I had previously installed on the tablet. All seems good but I get a 'Trust - System security' notification every time I reboot the tablet saying 'SELinux is not enforcing, your security has been weakened' - is this normal? Is there a fix? Many thanks.

Yes, that's an expected behavior since SELinux is configured in permissive mode (temporarily, until all bugs and policies are fixed). You can either disable Trust, disable its notifications or ignore them.

Thanks for all your hard work and time you put in on this @Rortiz2!

Can I assume the inability to playback videos—be that in HBO, Netflix, or FuboTV—without them being choppy as all get out is related to the known "Hardware Decoding (OMX - 1080p video playback" issue?

I guess so, I never tried streaming apps personally since I don't have accounts to do so.

I'm reinstalling your Lineage 14.1 to see if it's there, but I'm also willing to come back to 15.1 and troubleshoot if you are willing to walk me through it.

Hi,

Thanks for your interest, I will let you know if I need some people to test me these streaming apps.

No, the bug is also present on LineageOS 14.1 (it has never been fixed in ROMs that are Android 6 or newer).

Unfortunately, as I have mentioned a lot of times, fixing OMX will be the hardest part since we're using outdated Android Lollipop (5.1) proprietary blobs.

I have found a possible solution for this problem, but it will take me some time to fully fix it since I need to upgrade the OMX stack to Android 8.1 (and probably the graphics stack + the kernel drivers).

I've also updated a lot of stuff since the latest release of the ROM (and I still have a lot of work to do before releasing the next version of lineage-15.1).

What I should have wrote was that I was reinstalling because it isn't there; that is, I was using 14.1 before upgrading to 15.1 and there was no choppiness... And that leads me to believe it might have nothing to do with the OMX piece.

Again, thanks for helping to keep this device relevant!

I see, I guess it isn't related at all with OMX then. Would you mind getting logs from both 14.1 and 15.1?

    Just wanted to take a moment to thank the OP, this ROM has breathed new life into my douglas.

    Not sure what's wrong with MicroG then. The patch is there (and applied, I double checked it). Can't do anything else, sorry. As for giza camera, try to grab boot logs, they should be different now.

    @Rortiz2
    I'm enjoying LineageOS 15.1 so far (Douglas). I see that deep sleep is a known issue. Is there a way to manually force a deep sleep? And do you think the deep sleep problem is something that could be fixed in the near term, or is it more a long term, to probably can't be fixed sort of issue?
    Unfortunately, I'm still not sure of what's causing deep sleep to not work at all (even though I tried to debug it a lot of times). So yeah, I can't give you an exact date (or estimated) of when I'll fix that issue.

    @Rortiz2 This may be an unpopular opinion, but I hate the default typing sounds on LineageOS. I'm not sure if it's kosher to replace them in the distribution image? If so here is a copy of the iOS typing sounds:

    They just need to be placed in /system/media/audio/ui
    I would prefer to keep the LineageOS sources as stock as possible. You might hate the default sounds, but other people might like them. So yeah I think it's best to just leave them as is and let users change them afterwards if they don't like the defaults (like you did). As a side note, since these will be overwritten every time you update the ROM, I would recommend you to create a ZIP that replaces the sounds (so you can just flash it after every update) or set up some kind of addon.d script.​

    • Fixed camera.
    • Fixed internal storage (OBB) issues.
    NOTE: Video recording isn't working at all, it crashes with the stock camera app but it works with some third-party apps (such as Telegram).
    NOTE: Let me know if obb issues are fully gone (I basically reverted the sdcardfs squash update). Try to clean flash the ROM as well before reporting if the bug it's still present.
