[Galaxy Note 8.0 (Tablet) General] gooberdude:
OK, I tweaked a tosser 4.4.2 GT-N5110 to see what if anything, is worth all the troubles.

I can say is there is too many issues with stock 4.4.2 that peeps have kept quiet with.

Here are the issues that I am unable to resolve...

App drawer pops open after lock screen wake up.

Multitasking sux... Will pause ui action during app installs.

Build.prop mods don"t work as well as before. Best not to modify. Hosts and gps.conig files work as before.

Lots of odd background apps to mess with tracking user interaction with apps.

Tricky to tweak with trickster mod.

Random resets when having multitasking bog down.

Still a bit of work is needed by developers in fixing apps. As of today BBC IPlayer is working with perfect picture playback and with downloaded programmes. Hulu still sucking hind tit on playback issues with 4.4.2.

Things I corrected to allow for stability and performance...

Set my router to allow for sleep packets down to 90ms intervals, and set the tokens to 5 in the advanced features. I now have strong signal in weak areas of the house. Gained an extra bar or two. Downloads have steady 4MB/s peaks at times, with a link speed of 72mb/s at the router on a 20Mb/s modem. For those who are unable to grasp speed and connectivity... WIFI has high amount of overhead on connection speed. 72mbps / 9 = 8MB/s, so ruffly half of 8 (WIFI overhead with parity, packet size, security features and so on) equals 4. So 4 MB/s is about max until I am able to connect above 72mbps at the very old wireless router. Time to get a Netgear for xmas!

Tweaked the CPU cores affinity in trickster mod to allow for better power management in moderate use age. Able to keep temperature hanging around 78 degrees F under browsing minor tasks. Thus no need to have power savings mode on.

Replaced Samsung keyboard with Kii Keyboard and customizations. smaller app size and better layout. Though left and right arrow indicators are greyed on the cursor control keys. Might or issue, as every keyboard has some issue.

Added two of the only kitkak bug fix apps on Xposed, there must be more patches to be done to make it stable.

So far after a few days of messing with 4.4.2, I have pretty much made it livable, with rooting and adding most of what I use on my 4.2.2 for Xposed customization and tweaks.

Just 4.4.2 is a different animal in using the long line of tweaks most have used in Jellybean devices, memory management especially.

Oh, first thing was to uninstall Knox in the app manager... easy peasy, no hacking or rooting to do that.

So far both OS are fast and battery friendly, as long as Samsung DVFS is disabled and Google Play Music is removed. Tried the new Xposed media optimizer... all it does is delay the media scan from finishing promptly. It is not a media scan issue, as 4.4.2 is terrible with multitasking. Until I find the proper I/O timing with the device, swap priority and interleaves will always be an issue that will plague smooth multitasking.

Google screwed the pooch with ignoring Samsung instead of working with them. As long as you get two dominant personalities to conflict, they will never be as big as Apple or M$.

Also google's mindset is stagnate with tablet vs phone capabilities... Phones are not tablets so why make tablets with phone like lollypop or material design. It wastes 20% of the table's screen in useless formatting.

So either way you can have either firmware and be happy... just 4.4.2 is buggy by design and by lack of developer knowledge to work out the wrinkles. 4.2.2 can work speedy and have excellent battery usage with small tweaks.

I will post my Trickster Mod settings for better affinity with both 4.4.2 and 4.2.2 later on.
