I am seeing "SafetyNet API Error" in Magisk.

For anyone interested: I have the same error on three other devices running LOS 14.1, 17.1 and 18.1. Since one of those devices (the only one I happened to check) was passing SafetyNet yesterday, but failed today without having made any changes to the system or Magisk, I'd guess Google changed something today in the SafetyNet API and broke that functionality in Magisk, and the issue is probably not related to the latest OTA of this ROM.

Edit: John Wu has fixed the issue on Magisk canary, and will push a new update soon. @html6405

La batería cuando llega a -20 falla, la tablet ejecuta el proceso shout downd. Quė es el que debería ejecutar con 4% no con 20. La enciendes y puedes seguir apurando battery un rato.
. No se si rootear y meterles la app de calibrado de battery. No quiero rootear ...

la he conseguido descargar hasta el 4%, que se ha vuelto a apagar, avisando eso sí y la he puesto a cargar. También, despues de varios flasheo y 2 otas en 2 días, es normal que la batería se resienta.

Translation:
When the battery reaches -20 it fails, the tablet executes the shout downd process. What is the one that should execute with 4% not with 20. You turn it on and you can continue to drain the battery for a while.
. I don't know whether to root and put the battery calibration app on them. I don't want to root ...

I have managed to download up to 4%, which has turned off again, warning that yes and I have put it to load. Also, after several flashes and 2 otes in 2 days, it is normal for the battery to suffer.

Hmm you're right, I also guess that google changed something, let's wait and recheck this soon.
I've testet a older version of this ROM just to make sure, and it's the same behaviour.

If you want support from me, please write in english, if you can't, use google translate, I won't use my time to do this by myself.

Your log is nearly empty, I guess because of Selinux.
Type:

adb shell
su
setenforce 0

To disable Selinux, try to access storage (now it should work because of disabled selinux)
and do again a syslog, then I will find the missing rules.
I'm sorry, I'm not quite sure where to put these commands.
Type:...

And in general, I'm not sure what can be added to the log file. At this moment everything is working. Access to the internal stirage appeared after a clean reinstallation of one of the earlier versions. It is unlikely that the problem can be identified now on an adequately working version.
Frankly the UI speed has somehow decreased. And after installing version 18, there were also unpleasant oddities in the screen behavior. Violent flickering and a spot in the upper left corner, on which the white color remained a cold shade even when the night mode was running.

Here's a video I've made for the n51xx, but this won't make any difference.

So if you are still facing some issues, do what you see in the video, perform the actions which are causing problems, take a log and send it to me.

Hi,

Thank you for this ROM and for your work !
I flashed it on my GT-N8000 yesterday and it seems to work pretty well... However, I encounter the following issues :
- Maybe it comes from my device but I cannot charge the battery anymore... Initially it started to charge from 1-2% as usual but it has stopped at about 20-30% without any visible reason (no more "charging" indication, plugged in during 24h)... It has been several months I had not use this device so it may be because of an hardware issue (The battery has never been changed). Would someone have any clue on how to diagnose the issue (HW Vs. SW) ?
- Wifi connection does not always SEEM stable as several apps tell me there is limited Internet connection from time to time... I have been able to browse the Web and to install apps but still... sometimes network seems lost (But Wifi icon always shows "connected" state)... maybe it is more related to the next problem.
- The tablet seems slow from time to time with basic apps (lags)... maybe I cannot expect more from a such old device on Android 9 but I feel like this slowness could be related to the wifi issue (heavy load => connection issue or connection issues => feel like apps are stuck/slow). Does anyone see something similar ?
- When using Netflix, there is a blue horizontal thick line at the bottom of screen (as someone already told about)
> I have not tried old Netflix app versions (as recommended) for now.

Anyway, thank you for this again !

you could measure the power current / voltage with a USB amperemeter, but it could be your cable / charger / dock connector / charging ic...
Have you already tested another cable?

If your router is using 2,4 and 5 GHz and if they are sharing the same SSID, rename one of them, try to use 2,4 GHz.
Also PMF could cause problems sometimes.

Did you check for updates?

    First of all thanks for your work.
    Everything is perfect for me, super fluid, and faster. I had LineageOS, a ROM, from 2017, super slow. The only problem that continues is the reproduction of some videos on the web. They get stuck, they are not well decoded, green stripes appear. Are you missing codecs or is it a problem with the video processor that is not able to reproduce them?

    I'm also anxious to move to 18.1. Html6405, what do you advise?
    LOS 18.1 is a alpha test version, so I would not recommend to use it as a daily driver, there's still much work to do and there are many problems which need to get solved.
    LOS 16.0 is on the best way to be the best ROM for the next years.

    Hi,

    here you can find my LineageOS 16.0 for the Samsung Galaxy Note 10.1.
    At first I want to thank @forkbomb444, @rINanDO, @ChronoMonochrome and all the others who are working on the exynos 4 devices, you deserve it.

    I'm working nearly every day to improve our N80xx devices and here you get a already stable version.

    Here you can see what's working / not working:

    N8000, N8010, N8013, N8020:
    Boot
    Audio
    Bluetooth
    Graphics
    Cameras
    Sensors
    Wifi
    USB
    Video playback (HW/SW)
    OTA Updates
    RIL N8000, N8020
    GPS, not sure if completely
    Tethering via USB, WIFI and Bluetooth
    consumerir transmitter
    • Main camera sometimes can't take a picture in full resolution, you could simply reopen the app and retry, or you lower the resolution.
    • GPS sometimes looses the sattelites, after this error occur's reopen completely your navigation app.



    If you are going to use Gapps,
    I recommend to use the pico package!
    https://opengapps.org/
    For the others, you can use microG if you want, I've enabled signature spoofing.


    Do you like my work?
    Than you can simply hit the thanks button and consider to spend me a coffee or a beer,
    I'm doing this in my free time and it also costs a lot of money to buy hardware.

    donate

    You could use a gps.conf from https://app.box.com/s/w57s1v1n3hie7l5lk28i for your location and replace /system/etc/gps.conf.
    Or you try GPS Server Optimizer app for a faster 3D fix.
    For both methods you need root rights.

    I'm sorry people,
    because I've created a new domain wifi related,
    it made some existing rules uneffective.

    I'm working hard to run selinux without any neverallow rules (I'm nearly there) to provide the best security.

    To get wifi working again, type with your PC or terminal emulator:

    adb shell (only with PC)
    su
    setenforce 0

    and wifi will work again, there will be another update today with the new fixes.

    Hey, I just installed this to n8005 and you saved me from buying a new tablet. It works beyond my expectations. This is 8+ years old device after all. You are also helping environment too. Companies should do what you are doing instead of removing chargers to protect the environment. You seriously deserve donation. Have a nice day
