Hello all,
Following XDA for years, but wasn't posting that much. My apologize for that, trying to give my contributions now
So, to start, hereunder, a sum up of my recent tests over last German ICS rom, Stock XXLRG.
======================
This is the second version of this post, taking in account various comments so far.
Firtsly, this is aimed to share my feelings about my own experience. Hope this could help anyone in anything. Nothing more
Accordingly to Roy_W, I provide which I will call my "test phase" description at the end of post, as simple infos for you to better make your opinion according to your own use. It is not about precise calculations & results, but about comparing the same things.
Hope this helps.
======================
Tests
1. Stock LRG + Stock Kernel, No root
2. Stock LRG + Stock Kernel + Root + remove some samsung apps.
3. Stock LRG + Speedmod 3-7 + remove some samsung apps
4. Stock LRG + CF-Root LRG + remove some samsung apps.
Impressions
1. In my opinion, do not use this setup. Rom feels very laggy, many little freeze here and there but the must annoying is the battery drain and heat while wifi download.
I think this is due to screen ON + heavy download (1GB+, games like Max Payne or Nova)
Pen is not well reponsive also.
Note : Except in test 3, there should be no difference with pen responsiveness between 1,2 and 3. but that was the case to me. Dunno why ^^
2. Starting to feel better, due to the removal of some Samsung apps (Rooting should not have this kind of effect .
Complete list of removed applications at the end of this post.
The phone is more responsive, lesser lags, but other things from test 1 (battery drain, pen responsiveness) remains the same.
3. Very good setup.
Lags are mostly gone, and Pen responsiveness is far better.
Don't know if Speedmod have done some special work for that, or is just due to his overall tweaks. I think it is also related to Samsung S-Suite updates. (look at test 4)
Good battery, feels like it could be better but mostly due to Samsung Roms than kernel. With normal use (sms, few calls, internet, XDA app , new review, some always active sync like Weather, Gmail, Talk, ...), you can easily achieve 2 days (48h) before running out of juice.
Also lesser memory consumption in idle (maybe related to samsung apps that were removed)
But, bluetooth was not working and since it is a must have for me, I needed to go to test 4.
4. Currently in test. Don't have my bluetooth headset with me, so this test will be updated tonight or tomorrow for feedback about battery, bluetooth and other.
So far, overall responsiveness of the phone is ok, but not as good as with Speedmod.
Maybe a placebo ( ), but I always felt that Chainfire's kernel is behaving a little better than stock one even if the only difference is root rights.
Also lesser memory consumption in idle (maybe related to samsung apps that were removed)
Samsung Removed Apps
Always doing this since my GS. It always make the system smoother to me. Can't tell about battery save.
- All Hubs (Reader, Music, ...)
- All apps related to hubs. (Zinio, Press reader, kobo...are examples of ones eating too much storage space).
- the big one : Samsung social Hub (2 apks)
- All stock live wallpaper (storage space eater)
I did not removed the Kies apps, since there were never launched, do not bother me and was having some weird warnings about missing apks while trying.
I advised to keep All Share (which is functionnal and useful for cross hardware connection) and Samsung Apps (but deactivate sync from app settings)
Go also for setting, and deactivate Wifi sync for system updates (About Phone -> System updates).
I did not test NOTECore kernel which has good feedback (3.1 version) because of the bluetooth not working.
Test Phase
Mostly due to my work, I have quitely the same daily use.
- Kernel were flashed the morning, at full charge, with cache/dalvik cache wipe.
- Only 3G, no Wifi/GPS/Blutooth. Auto Brightness, no added/removed apps (except for tests cases above).
- Betterbattery stats, stock battery monitor and Go power master for battery monitoring
- Facebook sync off (for battery save)
- Gmail sync on
- Google+ sync & Instant Upload off (for battery save)
- Weather sync every 4 hours
- Samsung apps sync off (for battery save)
- 1h call
- Gtalk & Whatsapp always connected
- No Flash installed (feels like I should mention this)
- No kills or memory clean
- Fixed wallpaper (for battery save) & lesser lags for screens transitions and opened drawer using NOVA.
What I take into account while making my opinion about battery :
- screen on time versus battery lost for the same period of time. Having used different 720p androphones, I have my own appreciation of that.
For 2000mah full charged batteries in my use with full stock, 2-3h screen on time is really bad, 3-5h should be considered as a good average, 6h+ is a dream.
GNote has a 2500 maH battery, so I have my expectation and maybe that's why I feel bad battery bahaviour when it won't hurt you at all.
- if apps were differently used by me according to their respective impact on battery
- if the basic services of Android are stable towards battery (custom kernels often reduce that )
- any wake locks
- if battery seems not affected by side-effects like mentionned above, then wait for one week of use before stating.
What I take into account while making my opinion about smoothness:
It is about shutters between screens transition, apps transition, feeling about time for the usual apps to be launched, multitasking...nothing more that a simple user feelings
Bests
thanks for the tests... but we prefer the wiping tests... just kidding...
thanks for the info,
which method do you use to remove these apps please ?
Haha..only wipe caches & dalvik from speedmod and CF kernel. I won't take any rosk from stock kernel
For system apps removal, jusy need root and titanium backup

CF-root and stock kernels are identical. No tweaks. Nada. Just root and Clockworkmod recovery.
So, how can the phone lag with stock kernel and be OK with CF-root ???
Placebo ?
Maybe related to the init scripts. For sure the main thing is the root with this kernel but wihin these tests and also for all samsung devices I had with Cf, it were always behaving better.
As I also said, should be related to samsung apps removal, especially the hubs.

So far, overall responsiveness of the phone is ok, but not as good as with Speedmod.
Should be related to various tweaks, and ChainFire always aimed to provide his kernels, with Root and few tweaks.
I had GS, GS2, and CF kernels were always really nice for those looking to a Rom not too far from Stock, but with some performance tweaks and root.
Also lesser memory consumption in idle (also related to samsung apps that were removed)
BUT, having some troubles with NOVA with this setup. Several freezes, and needs to restart the launcher.
I think it is related to root access which needs to be set again coming from Speedmod to CF. Will keep you informed.
Samsung Removed Apps
Always doing this since my GS. It always make the system fly
- All Hubs (Reader, Music, ...)
- All apps related to hubs. (Zinio, Press reader, kobo...are examples of ones eating too much storage space).
- the big one : Samsung social Hub (2 apks)
- All stock live wallpaper (storage space eater)

Got to be honest I disagree with a lot thats written here.
Point 1 :- Why shouldn´t we use this set up??You might have or had problems but a lot of other users don`t,me being one of them.I have had NO laggs,my battery doesn´t heat up that much with WiFi,nothing freezes and the battery life is 100% top,all what you did in Point 3 with usage I get in Point 1 plus a few hours more.
Point 2 :- Once again I disagree,I´ve had no problems what so ever,only rooted for a few extra apps and removed NONE of the Samsung apps,still fast and smooth.Battery life still top,even upto 3 day usage depending on what I´m doing.
Point 3 and 4.....can´t say anything about these points because I won´t go this far,why should I ,everything is super fast,no laggs,a lot less battery drain:good: no need for any mods.(bluetooth also works )
Maybe I´m one of the lucky ones with a good Note :laugh:but this report won`t help me,maybe a few with problems.
Hi I think you don't agree wih my report cause of different perceptions between you and I.
Battery perf is linked to what is acceptable or not for both of us and also from various comparison through many flashes since GB.
And for sure, Linked to the type of use we both have.
It is the same for smoothness. I must say I am very sensible to lags and freezes even milliseconds one For instance, I am so maniac with it that I can detect a lag in a movie while no one noticed around me.
Plus, you can tell about many things to explain mobile OS perf and I will not accept this since I can not accept that a phone running a spec near to a PC ones, suffers such perf issues.
The best example is the smoothness experienced with my nexus with Jellybean against ICS. It is day and night.

Thanks OP for the comparison :victory:
Good initiative from OP for the comparison. Each person use the Note in a different way and will have different results surely from OP. But the main point of this thread was to give us a basic idea on the different setups OP has used. Thanks!
Thanx for making thread with detail study, thogh i can not be agree with many of statements.
Here something i like to say
- There is nothing much difference between test 1 & 2 except you have Root and removed some applications.
So does it mean
*Rooting can improve performance - I dont think so
*Removing application just making space on system ROM, so does making room on system ROM, can increase performance? I dont think so
many application you have removed may not be activated on start, naturally that doesn't have any relation with performance, b'coz it just occupy space not RAM
Now some application which may have enabled on boot, even that gives you temporary extra RAM, As android itself have LMK(low memory killer) which auto kills background applications which is not in used - LRU(least recently used), and when there is enough RAM available, even you exit from applications it remains in background for quike reopening, that is basic android mechanism. So if your aim to remove some application to make available more RAM, it won't be fulfilled, b'coz that application will be replaced by recently used application by users till android system dont sense as RAM is full. (you ca test it - when you have many applications removed, sure you will have much free RAM on boot, but if you look again after 15 min of play with device, it will be again full, same as who dont have remove blotwares, so wat benefits we got by removing those?)
Yes atleast i can say applications which was running in background for some time can consume little juice, but if you believe me, my experience is it can save maximum 3-4%(of full cycle) nothing more than that. But performance? I dont have any logic to believe it.
-I can't comment on test 3, as i have never used any custom kernel, and leaving your opinion untouched.
-Again between 2 and 4
yes you have also not tested much, but somewat if your opinion goes in favor of 4 (as you said in 1&2 responce is not good but in test 4 you saying it is OK) then if i am not wrong chainfire himself said, his kernel is complete stock (minus mmc_erase_cap command +root+su binary+CWM)
so in that case your opinion may not be placebo?
Anyway dear don't feel bad. appreciate your workout, but some points which i said dont favor me to agree completely.
Regards
I think my note must have been XXLRG when I got it but after trying to do some rooting things and bricking it, then finally loading XXLR1 (ICS) It is working great with no lag or freezing what so ever. Also have scored up to 4050 on Quadrant!

I have to agree with this post. I didn't recognize any of the problems stated in the 1st option. I am currently running stock everything after having tried several different combinations of ROMS/Kernels.
There is also a lot of missing information in relation to what exact tests were performed and how they were measured : Whats apps were running at the time, were Wifi / GPS / Power Saving active, what was the state of the battery, how was "lag" measured, what brightness setting was used, Was a good 3g station nearby or was the telephone continually searching for a stronger signal, etc etc etc , The list could go on eternally.
As for anything batttery related, I do not understand how tests can be performed that have not been run over a relatively long period.
There are far too many parameters and options possible, that it would appear that the tests are merely personal interpretation.
I appreciate that you have taken the time and effort to do the testing but I am not convinced that the results can be treated as anything other than one persons thoughts at a given time.
I think that you can only perform these kind of tests when they are performed "identically" on a device that is reset from scratch and that the tests performed are measurable with precise calculation rather than the human eye/sentiment.
It is an almost impossible achievement outside of a qualified environment with a very strict set of controls.
Can the results be reproduced, is there any possibility that the results could change, would a third party be able to reproduce the same results ?
Unless of course detailed results and calculations are actually available, in which case it would be very interesting to be able read them.
Hi Dr. Ketan. Again, thanks for your guide, test 1 & 2 was done following it
Do not worry, I won't feel bad about your feedback, as for the previous one.
For sure, I think you and Chainfire knows that type of things better than me (no needs to tell why ^^), just reporting here my feelings over my tests.
*Rooting can improve performance - I dont think so

Removing samsung apps does not affect that much battery, but smoothness. I certainly wrongly express myself.
Maybe CF kernel has nothing to do with it since I was always flashing this and removing the hubs (especially the social one) together.
But fore sure, since my galaxy S, even on the S2, and now on the NOTE, doing this does increase system smoothness.
I do not know that much about Android memory system managment, but the first time I've done this was because I was sick about seeing these services running in background, even without ever launching them once and it does consume memory.
Yes atleast i can say applications which was running in background for some time can consume little juice, but if you believe me, my experience is it can save maximum 3-4%(of full cycle) nothing more than that.

I believe you without any problems
You know the deal, 1% here and there...at the end, it saves some battery.
I will update my post, but I can now say that Speedmod provides better battery than Stock/CF, looking at my battery stats for today.

Many good hints in your posts.
For sure, I've made my tests with some knwoledge about that, and trying to be in the same scenario each time.
I will update my post towards the parameters activated and other you stated.
Thanx
yes custom kernel may have improvement, b'coz that is made for that purpose, and we know developer adds some tweaks to improve performance. though i have not tested it, i can be agree on that point. but i have not make review just b'coz i have not used.
Regards.

Phenryth,
I look forward to your results, the basic idea of what you are doing has the potential of becoming a very interesting article.
These are tests without any statistical significance.
So in the end your heart or gut decided.
Everyone has there own view on how their phone should perform. If you are happy with it then there is no need to change it. If not then this guide provides some tips on how to improve it.

To me for the first time ever since the ICS was introduced the 1- setup is absolutely the best I have tried, and I did try all four of them including removing Samsung bloatware.
The touch response is super sensitive, the pen works not just perfect but it also marks when in a diagonal position something never happened before, my one and only complain is the same one since seven months: the lag which comes when opening the Contacts application for the first time ,which is absolute outrageous other than that I am satisfied.
Full Details about latest 4.3 XXUGMK6 (BTU) Official
So basically I decided to publish this thread about latest official( Un-rooted STOCK) 4.3 XXUGMK6 (BTU) Official firmware.
I tested this firmware as already many of you already did. But I find some bugs or 'Mistakes' in the firmware.
]DETAILD ISSUES
1.) Music Player (STOCK)
-Adapt sound option enhancement is not added in galaxy s3 4.3 firmware.But in GS4 it is present.
-Music playback is not well. You might find playback is fluctuating at some point. I performed hard reset and then tried again but still it is present. and Even tried on my other gs3 4.3 and problem still occurs although it is occasionally happening but its still present. My other friend using S3 have same problem So i think its a Music player problem.
-Share via option has been removed from music player. ( see the attachment).
2.) Very high RAM usage.
- In previous version 4.1.2 XXEMG4 ram usage was actually normal. But I find that 4.3 JB has more usage than previous one.
3) Poor battery performance
-I hardly get 18 hours battery in normal usage. and with gaming and wifi its about 12 hours.. All other custom roms out there (even CM) has far better battery performance.
4.) Setting FCs
-In setting -> Security-> Sim alert change. is not working. My setting menu keeps force closing. and my both S3 has got same problem . I performed HARD reset but still Its a BIG BUG.
I attached screenshots.
and Yes there are no GS4 Goodies like "SMART FUNCTIONS","LENS EFFECT","CAMERA",etc.
at least they should give us 4.3 360 degree feature. But no. its not.
Well there are some good things about this firmware too.
1.) Graphics are really improved You can easily feel the change while playing games and watching videos.
2.) Some how transitions effects are smooth than previous 4.1.2 .(till now)
3.) New Touchwiz theme looks pretty decent.
4.) and other few.
Basically I wanted to know that what do you think about Samsung whether you are gonna update your device with same company or swicth? because I felt they just ignore previous FLAGSHIP phones just to improve there new ones.
Please add your review about this firmware too in posts.
Try lastest ML2 firmware or neat rom, and greenify apps like facebook and facebook messenger, turn off S-voice, turn off google play service, and basically turn off everything else your not using, then restart the phone and see the ram difference, if still high open application manager and check whats running and close it.
Mod Edit

Hi guys,
I ordered a GNote 3 and I'm really excited. But I read a lot of stories about the lollipop really buggy, memory leak, and battery drain. But I don't see many comments about these in the ROM thread, and someone mentioned that they like Stock lollipop better than CM12. Does this mean stock lollipop for Exynos is working fine? I don't have the device yet, so I have no way to try out yet myself, but I plan to flash my desired ROM right away when I get the phone. It could be one of the TW lolliop ROMs or CM12.
Just a note that I would love to run lollipop, and not kitkat. So could you please advise around that? Are there tweak that people use to fix the issues?
Thanks!
Hello!
Right now I have over a month testing the stock LP ROM on an exinos device, it has been quite a good experience, the ROM is very responsive, and although it has a huge memory leak (I have found my device running on RAM as high as 85% with no running apps, just running the processes needed for the OS to run) nevertheless I can harddly notice any lag n the system, I use Clan Master to monitor RAM usage, when I find my device I use the clean now feature, and the RAM usage goes back to around 60-65%.
On the battery subject I run my Note 3 paired via bluetooth with a Gear S, and I am getting between 20 to 24 hrs. Of continuos use, so taking into account I am always running with bluetooth on, I think I am getting a pretty decent usage time, I would like to let you know that I mustly connect to the internet via WIFI, only use Celllular Data when driving or in places where there is no WIFI available.
After installing LP ROM I went straight to rooting my device and installing Titanium Backup in order to be able to debloat, I have managed to uninstall APK that I found useless for me, and got rid of them, also I use Greenify and I have greenifyed every app not essential, I also use Startup Manager ( Free) to get control over what apks startsup.
Finally, I use tasker to get control over how my device handles the changes between Cell Data and WIFI.
I hope you find this information useful, and please excuse my english!
Hi, so I've had my G2 D800 model for a while (about a year or two), and for the most part, it's been an excellent phone despite being 3 years old now. Never had any slowdown problems, and it's always performed well in games and in general.
But just recently, about a week ago, it just started lagging out and being very, very slow.
For example, if I'm watching a YT video through the app, if I rotate the screen, it takes maybe 5-8 seconds to actually rotate. Also, in a lot of circumstances where the keyboard has to pop up, it just freezes the app until the keyboard pops up maybe 10 seconds later.
It's also just laggier in general in most apps, scrolling through FB or Twitter freezes nearly every second when I'm scrolling. It's generally unresponsive and sometimes just freezes outright. It also acts this way on the homescreen, and in most everything else.
The most annoying part, however, is that sometimes the devices just doesn't turn on for sometimes up to 15 seconds after pushing the power button (and it usually just refuses to turn on when using my knock code).
The odd part, however, is that once it's actually in something like a game, it performs perfectly fine.
I've played a number of Cardboard games, as well as games like Nova 3, and it performs perfectly.
I've also ran multiple benchmarks (Geekbench, 3DMark, etc), and it scores around where it should.
Info about the device:
LG G2 D800
Stock Lollipop 5.0.2
Software Ver. D80030f
Kernel Ver. 3.4.0
Rooted
TWRP Recovery installed
XPosed Lollipop installed
G3 Tweaks installed, a number of tweaks applied
Everything else is stock (homescreen, etc)
What I've tried/checked:
Checked memory usage during "lag sessions", rarely dips below 300mb free
Changing minfree values through Rom Toolbox (tried every preset, as well as setting everything to the max to free as much as possible)
Rebooting (affects nothing)
Checked CPU speed with Rom Toolbox (is at max, and does achieve the max speed of 2265 MHz. Setting it to performance mode/setting the min speed to be 2265 MHz has no effect, but reduces battery time)
Changed default cache sizr (tried every preset from 128kb to 4096kb. With multiple benchmarks, the optimal value for r/w bounced between 512kb and 4096kb, currently on 4096)
Things I have not tried (that I am aware would possibly have an affect):
Changing anything in the kernel tweaks/build.prop
Completely wiping, reformatting, and reinstalling (I really would rather avoid this if possible, as it would take a while to get everything back to what it is now, and it was a pain to upgrade to Lollipop in the first place)
I am unaware of anything else I could try to fix it, which is why I'm here
So, does anyone know of any other solutions or things to try? This has made my phone very unreliable, even for phone calls and messages, which is a problem.
Thank you for your time and help!

Hi,
First thing i need you to try out is this custom kernel : http://forum.xda-developers.com/lg-g2/development/lp-5-0-2-kernel-3-4-107-dorimanx-1-0-lg-t3102512
Then install greenify, and hibernate all the unnecessary apps.
This should solve the issue.

Thanks for the quick reply!
I'll try out greenify, though there aren't many unnecessary apps running (i uninstalled all the bloatware first thing, when I rooted).
And about the custom kernel, it's something I've never tried, so I have a couple questions.
Will it wipe my device, or break TWRP, root, or Xposed? (Sorry, didn't see the answer on that forum)
Will a TWRP backup I make be able to fully restore my device to it's current condition?
Is everything that is supported on my device be supported with that kernel? (Apps, etc. Don't know a whole lot about how kernels work, so I don't know)
Thank you!

Is everything that is supported on my device be supported with that kernel? (Apps, etc. Don't know a whole lot about how kernels work, so I don't know)
Thank you!

Hi,
Even you uninstalled bloatware, the apps you use daily could be running in background and taking all those rams. So whenever you play a game or dont use a certain app, just go to greenify and hibernate. Since you have xposed installed, you can do more than that such as u can stop sync , etc.
About the kernel, it has a ram management settings and cron task.
Ram management dont need to be altered. It has some preset profile so if you seek performance, just choose performance or if u need battery , select battery profile etc.
Cron task is useful because it will do alot of things automatically. For example, it will release ram at certain amount of time from the apps , it will restart google play service since that could be an issue , etc.
All you need to do is take a nandroid backup just to be safe. Then download Dorimanx Ota from playstore and it will detect ur device and show u which version of kernel is available. Then download that, go to recovery, flash it, and you will see three app installed : Synapse -- will give you all the details of ur setup including cpu speed, temp etc for monitoring purposes
Dorimanx settings - this is the main settings of the kernel. You will see a P icon on top, tap it and choose your desired profile.
Color management : It is as the title says, just leave it be.
Then use your device, check your ram and report back. Hopefully it will resolve your issue.
Wow. Dorimanx did a lot more than I was expecting.
Downloaded the app, downloaded the kernel, flashed it no problem, went through and checked out synapse.
Went into the Dorimanx settings, and set it to the "Performance" profile.
Immediate improvement.
The whole phone seems a lot more snappy, and I switched back and forth between a 1080p60 YT video, facebook, and twitter with absolutely no problem.
Free memory when idle (no apps open) stays around 1gb; it used to be about 500mb before.
Tested a few games for the heck of it, and it actually seems to have improved game performance somehow. (It seems to have overclocked my CPU to 2.5ghz, though, so that makes sense.)
Temps stayed at around 58-60c while running a few Cardboard apps, so it seems fine.
Thanks for the help iubjaved! This has fixed my issue and then some! Ah, the wonders of the Android dev community.

Hello everyone,
As Android 10 and above seem to be a bit sluggish for this device, I decided to make an Android 9 LineageOS 16.0 build for my soon 9 year old SM-T800 tablet. It seems to be much smoother and stable then Android 10 and even while doing heavy web browsing, watching YouTube in 1080p or using Google Maps navigation in satellite mode, nothing crashed for me. The only issue I found is that the tablet gets a bit hot when actively using it. To sorta mitigate the issue, I recommend rooting the device, installing a kernel manager and limiting the CPU frequency to 1700MHz (where default is 1900MHz). The ROM itself has been very stable to use, only camera video recording and fingerprint scanner are not working as of now.
What works?
Boot
Wi-Fi
Bluetooth
Front and back cameras (photos only)
Video playback
Audio
Sensors
Flash
GPS
Microphone
What doesn't work?
Video recording in camera
Fingerprint scanner
Bluetooth is randomly hanging up when connecting peripherals
Offline charging
You tell me the rest
This build is SELinux Permissive!
Flashing instructions (clean flash):
Ensure you're on the latest Marshmallow firmware for your tablet
Use LATEST OFFICIAL TWRP, or LineageOS recovery (attached with the ROM)
Wipe Data and System partitions from recovery
Flash ROM zip from internal storage, SD Card, USB OTG or ADB sideload
Flash GApps (optional, my recommendation is OpenGApps 9.0 arm pico or nano)
Flash Magisk (optional)
Reboot and voila!
Otherwise, this ROM is good for users who wants better smoothness and stability and doesn't want to downgrade all the way down to Android 7.1.
If anyone wants a build for a model different than chagallwifi, tag me and I can try to build (You'll have to test it yourself!).

Do you plan on fixing the fingerprint sensor anytime soon? I use it on the LineageOS 17.1 build pretty often

For cpu temperatures/speed limits,
Which cpu govenor in the kernel did you use?
You could build a version with the kernel limiting to 1700Mhz so people need to mess around with root.
I recommend upgrading the thermal pads inside the tablet as well

The current governor I used is schedutil, I'll try setting it to interactive and limiting the CPU frequency next build

I currently can't find the cause of the sensor not working. It reaches the fingerprint setup successfully, but holding or sliding my finger on the home button doesn't seem to do anything.
Hi Just a quick question.. my understanding is that android 9 does not support dark mode, that your screenshot almost seem to suggest that it does.
my reason for asking is that I am visually impaired, and really can't read anything on a white background. anyway just wanted clarification before I try out this rom.
Cheers

Hi! Android 9 has a partial dark mode. The built in system apps as well as the system UI is dark, but third party apps do not support this dark theme and are light by the default. Many third party apps can be manually set to dark theme.

thanks, I think I'll give it a crack, i'm using the latest Lineage 20 build from another thread and to be honest it's super buggy lol. If this doesn't work out I can always go back to the 17.1 build which was actually pretty stable, but as you point out it's a bit on the sluggish side. Cheers
Or you might try unofficial LineageOS 18.1 (A11) which perfectly supports dark theme. I'm running it on my SM-T805 without any problems.

The problem I found with A10+ ROMs is that some slightly graphics heavier apps or even Google Maps in the browser can crash itself or even lock up the tablet completely.
For those graphics apps I can't tell. But Google Maps I use a lot and it's absolutely stable.

The app itself works fine, but the Google Maps website will likely crash when it's opened in a browser when starting to navigate around the map. And there are many other websites that do crash the browser as well.

Watching youtube works fine, as that's all i do with this tablet now, other than checking my email. Setting up the e-mail did freeze the tablet a couple of times
hello,
So I tried out this rom and wanted to report back my findings.
I found it to be both stable and fast, but there were a few issues, which has led me back to 17.1 LuisROM which given my particular needs really does seem to be the best option. I have actually tried both18 and 20, but neither of them are as stable as17.1, at least based on the particular set of apps I use.
Anyway, the issues I had were:
1) the partial dark mode support was certainly not bad, but given the fact that apps don't follow the system theme, and I could find no way of setting the Google app to dark mode, it was less than ideal. this is no fault of the build at all It's just a limitation of being Android 9, and I imagine for most people it would not be an issue nor a reason not to use this ROM
2) I had a weird issue when I shut the tablet down and plugged it in to power source. The battery icon showed and and then the tablet froze up, so that if I disconnected it from the power source the battery icon still continued to display and the only way to boot it back up was to press and hold the home key, volume down and power. this would seem to suggest there is an issue with the Kernal/ boot loader.
3) I have the official Samsung case with built-in keyboard, but there appeared to be a problem with bluetooth and I simply could not get it to connect. this was the deciding factor like to go back to 17.1
Cheers

Hello, I'm sorry for the issues you experienced with the ROM. I checked both of the issues and the offline charging issue seems to be there for me too. As you mentioned, it might be related to kernel, but I sadly can't find the actual cause of it as I'm still pretty new new to the world of Android development and I'm still learning how everything works. The Bluetooth issue is something I have now experienced as well. I tried connecting a pair of BT earbuds and they seem to be stuck at connecting at the Bluetooth page in settings. For now I'll update the known issues with those two bugs and maybe one day I'll find out what causes them. And by the way, since you now installed Android 10 on your tablet, how is it for browsing sites? Do sites crash often? Since this is the main thing I use the tablet for (and occasionally watching YouTube and navigation in the car).
Cheers

Hey there,
I wouldn't exactly call myself a power user, but I have not suffered a single website crash on the particular build I am using, Which I believe was created by a very knowledge Developer last year. It might be worth noting that I use Samsung Internet browser, Which in my opinion offers by far the best overall experience, Including a flawless dark mode option that seems to work for every website.
One thing I will mention about the spilled is that the developer seems to have gone AWOL and the download link to his builds no longer works. That said, I have a copy of the build on my google drive, download link SM-T800 Lineage 17.1
Give it a spin and see what you think, Overall I'm very happy with its stability and performance. Because of my visual impairment I mostly use audio based apps, such as Google Podcast, Audible, Poweranp Pro, But I also occasionally use Newpipe and VLC player and again, have not had any issues.
PS Good on you for creating your own build, I almost considered trying to do it myself but it's just too much to take on considering I can hardly see the screen lol
