Hello!

I know how lowering the resolution on PC's normally speeds up graphics and the overall usability. I was wondering if changing the resolution helps take out some of the lag and speed up the overall use of the tablet? Is it worth it?
YMMV. Try and judge it by yourself whether the screen quality downgrade is worth the multitasking and usability.
 
Hello friends,

I tried to update my old Samsung Galaxy Tab S devices with the latest Android 10 (Lineage 17.1). I would like to make the build available for you guys as well.

Special thanks to the teams at Exynos5420 and LineageOS for the sources.

Devices:
  1. Samsung Galaxy Tab S 8.4 WiFi (klimtwifi) SM-T700
  2. Samsung Galaxy Tab S 8.4 LTE (klimtlte) SM-T705
  3. Samsung Galaxy Tab S 10.5 LTE (chagalllte) SM-T805
  4. Samsung Galaxy Tab S 10.5 WiFI (chagallwifi) SM-800
  5. Samsung Galaxy Note 10.1 Edition 2014 (n1awifi) SM-P600

I will create new builds from time to time.

Installation:
1. Flash latest official Samsung Firmware with ODIN
2. Flash latest TWRP Recovery https://twrp.me/Devices/Samsung/
3. Wipe Data
4. Install ROM.ZIP with TWRP https://luis-builds.de/downloads/lineageos/misc/
5. Install latest GApps with TWRP (ARM/Android10) https://opengapps.org/
6. Reboot and Enjoy
7. Optional: Install Magisk

Download the file:

Sources:
https://github.com/LineageOS (LineageOS 17.1)
https://github.com/exynos5420/ (Kernel, Device, Vendor)

Greetings Frank

updated : I resize to 1200x1920 and increase ZRAM to 2048 MB, now i can watching youtube and surfing the internet at the same time very interesting for my workaround until next patch released
How were you able to do these tweaks? I looked at your previous comments and can't seem to find an option in hktweaks to add zram or change the resolution.

This might be somewhat off-topic in this thread, but my T705’s WiFi seems to not work properly anymore. It connects briefly to a network, then disconnects and no networks are visible anymore. Turning WiFi off/on sometimes makes networks visible again, but then the same problem appears when I try to connect.

Is this behaviour any of you recognise? Is is indicative of a software problem or a hardware fault?

Thank you very much - so far it is working perfectly after an upgrade from LineageOS 14.1 klimtwifi without going to stock ROM first. It did reboot twice during initial setup. I am very very happy to see that I can still use this amazing device, thank you so very much!

Update about cpu, exynos 5420 defaults is 8 cores but we only have 4 cores (A7 LITTLE) in this rom. moreover, after i digging in b.L i found A15 is offline all 4 cores which is big core, any idea how to enable A15?
klimtlte:/sys/devices/system/b.L # cat b.L_core_stat
0 1 2 3 L2
[A15] 0 0 0 0 0
[A7] 1 1 1 1 1

So far so successful, although sometimes apps like chrome close and have to be re-opened several times, thank you for everything
