For RAM it's probably better to tweak LMK, because Z-RAM kills performance.
I'm with you on that, you know what, I will remove the swap on my device and test it with high RAM consuming apps etc.
If it will pass, I will remove it for all.
I just have to take care whats best for all users.

I had the best stability with pegagsusq in my tests.

I had a really bad battery experience with ondemand, but everybody can change the default governour with kernel aduiator for example.

This is why I've set the value to 16000 MHz.

I had this in the early stages, but people wanted that I unlock higher frequencies.
Some devices run more stable with higher values, some not, I wouldn't recommend it.

Well, people claimed because of running out of RAM and I had many last_kmsg's because of that, it was necessary, maybe not for everybody, but for most.
Maybe we would be safe if I set the device to low_ram, but then some functions would be missing like pip,
multiuser support etc.
It's not easy to make a ROM perfect for everybody ;).

For this you will have to modify the ramdisk and delete

swapon_all /fstab.smdk4x12

in the init.target.rc.

Also, you could delete the
/dev/block/zram0

line in the fstab.
Modifying these files in FX File Manager with root did not work.
The ****ty settings return upon reboot.


Having to fork the ROM to fix it would suck on my 3 mbps or worse internet.
 
RAM usage is very low, but my device is almost always unresponsive with Z-RAM enabled, 100 swapiness, pegasusq. CPU is often at high usage as well. The worst stutters occur when attempting to switch apps. Battery drains pretty quick too.

With swapiness at 20, it's much more responsive... but still lags and stutters a lot, and that's also with the performance governor and deadline set instead of cfq (cfq is fine but i prefer deadline, since it gives more performance), and a more aggressive LMK.

Setting LMK more aggressive keeps the RAM from filling up as much, and also keeps more resources freed up for the CPU. Less programs running, less CPU usage.

Pretty much any device would become somewhat unresponsive if the RAM is filled, but having to constantly compress and decompress software (especially with an older weaker CPU like we have) will result in more stutters, even in general use.

Restart from zero (do also the wipes) and try an older gapps package, some people reported problems with the most recent version.

I've been running this firmware for a few weeks now and it works very well. There is one issue that I keep running into. I use the tablet for music and use a Bluetooth page turning pedal that sends keystrokes when a button is pressed. It pairs fine and turns the pages in my music app as expected. After a music session (often two or more hours) I turn the pedal off and recharge the tablet.

When I next go to use the pedal, the tablet claims the pedal is connected but keystrokes aren't reaching the app. I have to forget the pedal and pair again to get things working. With the old stock (4.4.2) firmware, the pedal reconnected correctly each time.

Any thoughts?

I tried all of those before I resorted to forgetting the device and repairing. Just to check, I tried these ideas again but no change.

One thing I noticed is that, even though the tablet says the pedal is connected, the two little dots that usually appear one each side of the BT symbol when a device is connected are not displayed. If I forget and repair, the dots appear as expected. After disconnecting by either turning the pedal or the BT off, it's back in the state where it says it's connected but isn't really.

    Just wanted to say thanks @html6405 and make a donation for sharing your custom rom, hard work and skills with us, bringing new life to this old tablet. I installed this on both mine and my Dads as he couldn't use certain apps with the old android 4.4.2 original firmware. Thought this one was the best option at the moment to get most usage. Amazing work! Thanks again Paul and a happy Frank (my Dad) :D Donation to follow (y)

    Hi @html6405, my n8000 is running LineageOS 14 but the performance is pretty average. With this Lineage 16 do you think the performance is better?
    Thanks for the work.
    It alway's depends on your installation, using apps etc...
    But in general Android 7 can run faster than Android 9 on these devices.
    I would simply give it a try.

    It's also empty :/, are root permissions granted?
    Yes.. Let me.try again later tonight…

    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.

    Attention: disable your SIM-PIN with a different device, otherwise it could get locked.

    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

    If you don't like it, reboot into recovery and type the following command:
    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.

    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

    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.
