Happy new year! Just clean flashed the new build and microg still claims there is no spoofing support. I'm using the magisk module (microg installer revived), if that matters.

Good morning and a happy new year to all of you! Thank you very much for the new ROM, I tried the Giza one right now, but unfortunately, the camera is not working (I tried with OpenCamera). And for MicroG: no signature spoofing capabilities right now. Appreciate your effort!!

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.

Thank you Rortiz2 for your kind offer! I appended a logcat when trying OpenCamera that I compressed to save some space (hopefully this is useful, since I haven't used logcat before). I personally am very happy with your ROM, as a working camera on that tablet is not important for me. Btw. MicroG reports missing spoofing capability on douglas with its self test just as well, but let's see what other users of your ROM report back ...

Well, I'm not sure it's microG, just used smali patcher to generate the magisk module and after installing it, spoofing works... so maybe the patch doesn't apply on 15.1 the way it should... Thanks for double-checking it was in!

will the microG patch mess with CTS/SafetyNet ?
 
Happy new year everyone. I have been using LineageOS 15 on my Douglas for a few months now. I've been having an issue with mesh WiFi for some time now. Instead of seamless switching as I move around the house, I get these disconnects, and reconnects. Has anyone else noticed this? There are no WiFi issues as long as I stay in one room.

Not a big problem in general, but causes some video streaming apps to stop buffering. I figure that is probably an app issue, where they aren't handling abrupt disconnects/reconnects properly. But I do not see this behaviour (WiFi disconnect/reconnect) with my other devices.

I am on the latest update at the moment, January 2022. I have a set of three Tp-Link Decos around the house.

Interesting, thanks for the report. Mind if I send you a zip in PM to see if the problem gets fixed?

Thanks for the log, but unfortunately it's kinda useless since I can't see how does camera init. Could you grab instead a log while you power on the tablet (Amazon Logo -> LineageOS bootanimation -> Home Screen)?

For me it also happens with one access point - I randomly see the Wi-Fi icon going hollow - not connected to any AP. That is with me not moving... I think there were reports about that before?

Hello everyone, new forum user here. Recently installed this build of Lineage on my Douglas, and just grabbed the latest update. All the major features are working fine. Only problem I have is the SD-card inaccessibility bug (device sees the SD card is inserted, but can't read any of the files on it). I'd love to see a patch for that, if possible. Otherwise, it's working much better than FireOS ever did. :)

    @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.
