[ROM][11.0 GO][SM-P600] Lineage 18.1 GO [UNOFFICIAL]

[DanielBR911]

LineageOS is a free, community built, aftermarket firmware distribution of Android 11, which is designed to increase performance and reliability over stock Android for your device.
LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.


Why Android 11 GO version? According to the Android 11 Go Edition Device Setup Guide, starting with Android 11 all smartphones with 1GB or 2GB of RAM must use Android Go.
Although this tablet has 3 GB of ram memory, this tablet has a technology of 8 years ago, I believe that the Android GO version can run in a responsive way with minimal lag.
In addition, some tweaks were applied to improve the overall performance for this old device.

*This rom is also compatible with SM-P601 but without 3G data network support and Phone.

Working:
> SD-card
> GPS
> S Pen
> WIFI
> Bluetooth
> Sensors
> Audio
> Screen Record
> Camera (just picture)
> IR Sensor
> MTP

*For now there are crashes in certain apps and in certain situations. The rom is only recommended for testing and not for daily use. As the solutions are discovered , they will be applied in future builds .

Hi @DanielBR911,

I will give a try in this rom!
I tried yesteday the LuisRom, but my P600 was get TOO hot, and sound crackling on Youtube.

Did you notice some of those in your build?

Hi @edu.mariano,
You should try this rom. I'm using this ROM daily and I'm not having problem with You Tube app, video and audio works normally. Please test this Rom and let me know if you are having any problems.

@ShevT has a build of LOS 17.1 where those sound issues were fixed.

Many thanks for this. I have installed and it generally seems to be working well.

1. Glad to see audio working well as it wasn't initially in 17.1 and only recently fixed.
2. I am using ShevT's 17.1 and he had managed to fix audio issues in 17.1 which I think were being caused by the CPU core control - after the fix the cpu cores run at almost top frequency all the time, even on the interactive governor. The same is happening in this ROM. This makes battery drain significantly higher and charging slow when the device is turned on.
3. I installed deathly auditor - in the 17.1 rom this allowed to tweaks battery charging current, however these are not yet enabled in the 18.1 kernel.
4. USB Midi OTG is working well.
5. My usb soundcard is not working (but was in 17.1) - in android 10 I used the lesser audio switch app to use the tablet speakers and the usb mic to together, but this does not work in android 11 as we are supposed to be able to select usb audio inputs/outputs through volume control - this is not available in the 18.1 go.
6. I don't think Palm rejection on the spen is working on this. ShevT had fixed this in 17.1.
7. Some streaming apps are not available on play store (D+ and NF) although this may be because I installed magisk, but this wasn't ever an issue on 17.1.

I will continue to use and test. Thank you for sharing this.

Change your device fingerprint in MagiskProps to a certified fingerprint in order to get Netflix to show up.

Are you also noticing that Wi-Fi disconnects randomly? And there’s also no on screen nav buttons

thanks for the feedback. I think Streaming Video like Disney+ and Netflix is not available on Play store because you are using a custom rom.

I noticed that Wifi sometimes disconnects when using 5 GHz. When using 2.4 GHZ, I didn't notice random disconnections.

I get Netflix and Disney+ to show up when I change over to a certified device fingerprint using the MagiskProps module

Good news : )

I am 5 ghz and haven't noticed disconnects yet. I watched a movie streamed over chromecast and no problems during that.

One of my key apps (koala sampler) is crashing as soon as it opens. A previous test version of 18.1 by the exynos team was posted briefly for the p601, but removed as there was a memory issue causing crashes. It was said it would only be available again once this had been fixed. Have you fixed this or do you know if has been fixed in the exynos team sources?

the issues started after I tried to use my usb soundcard, so it could be related to that, but would be good to know if there is still potentially an underlying issue before doing further checking.

Seems like with this rom, the memory issue hasn’t happened. I’m about to put this rom to the test with everything that I do on a daily. Also got Netflix installed btw

I never got a chance to try the other 18.1 version - did you notice app crashes on it? Certainly the koala app is solid on 17.1 and I'll be going to back to that for now.

On ShevT’s version of 18.1, there were many app crashes cause of the memory problem. It would get to the point where the system would randomly crash and reboot. So far with this new rom, I haven’t experienced any crashes (yet). There are some features that I do want to see in the next build though. If any errors do come up I’ll pull logs. So far this rom is a step in the right direction. I installed this rom with the Opengapps Super Package.

The other problem with 17.1 was that video playback in the browser wouldn’t work unless your webview version was v89 or lower. I’m going to see if that is the case with this new rom

Today I tested several apps. So far I've had a problem with Angry Birds 2, but other Angry Birds are working fine.
