Hi all

I would like to share my 2nd public sammy kernel+rom, yTab, to you guys. Hope you will like it. Enjoy!



T805 testers needed
pls send me pm if you are brave enough and want to be a tester for T805 variant, ideally with some knowledge for debugging or getting log files for me, and able to save his tablet in case of unbootable roms or bootloops (since I cant be online 24hrs to help u in case of emergency) which can happen likely. however, i cant tell if there will be a fully working version finally. thanks



NOTE:
  • for SM-T800 Tab S 10.5 WIFI only atm
    - this yTab ROM/kernel is currently built for SM-T800 only (exynos5420), other similar variants like SM-T800X or SM-T800Y are not officially supported
    - those come with Snapdragon processors are NOT supported too
  • warranty void
    - installing this ROM/Kernel can/may void your tablet's warranty, and resulted in Knox Warranty Void 0x1
  • overclock warning
    - overclocking can reduce hardware life expectancy and can damage the hardware or tablet
    - overclocking or under-volting results differ from device to device, and there is no such thing as best values for OC or UV


WHAT NOT TO EXPECT:
  • frequent updates
  • fancy installations
  • bugs free experiences
  • problems will be solved quickly/ultimately
  • individual/feature requests (i will listen, but no promise)


KERNEL FEATURES:
  • compiled with UBER Linaro 4.10 +Graphite
  • f2fs/ext4/ext2 support
  • single/double tap2wake with custom options
  • toggle between permissive and enforcing selinux **1
  • cpu freq from 100 to 2400MHz **2
  • gpu freq from 100 to 733MHz
  • max memory freq increased to 933Mhz
  • custom voltage settings for cpu **3/gpu/memory **4
  • custom settings for audio/charging, etc **5


**1 can cause apps FC if set to enforcing atm
**2 stable max cpu freq is 2000MHz (default 1900MHz for safety), while max cpu freq observed is 2100MHz so far but crashed a lot (temperate around 25-29C)
**3 default voltage for cpu = stable value observed + 20mV
**4 default voltage for gpu/mem = stable value observed + 30mV
**5 via my yTab Synapse Control or sysfs



ROM FEATURES:
  • supports mixed file systems of your choice, eg cache in ext4 and others in f2fs
  • custom boot animation support
  • enhanced UI speed, smoothness and responsiveness
  • dvfs disabled (cpu only atm)
  • all apps quad view/floating multi windows in both side bar or air command (spen) window
  • air command **1
  • dialer enabled for entering factory test secret codes, etc
  • knox removed
  • secured storage disabled **2
  • simple restart option menu
  • semi-transparent menu/dialog, etc
  • 5GHz wifi enabled supporting all frequency channels
  • supports synapse


**1 action memo, finder, screenshot, air command (spen) window
**2 secure storage is bypassed but certain apps/functions depend on it may not run properly due to version mis-matched with kernel sources provided by samsung



SCREENSHOTS:


DEFAULT SETTINGS:
  • tap2wake is enabled by default with 5 seconds delay (will set it longer in the next kernel update)
  • double tap is required to wake up the device by default instead of single tap
  • power key press is ignored by tap2wake but can be changed
  • selinux set to permissive, DO NOT set it to enforcing for now or otherwise apps may FC
  • cpu freq - min: 100MHz, max: 1900MHz
  • cpu freq big cores - min: 800MHz, max: 1900MHz
  • cpu freq little cores - min: 100MHz, max: 900MHz
  • gpu freq - min: 100MHz, max: 733MH
  • interactive cpu governor (recommended)


TODO:
  • add more settings in yTab Synapse Control
  • add color balance/control
  • 4.4.4 migration
  • include some Note 4 features including new air command, air clip, multi win, etc
  • start (really) to bring back my favorite TabletUI


KNOWN PROBLEMS:
  • secured storage and other apps or features depend on it like private mode wont work properly FIXED, will be included in the next update
  • draw target window action in air command not working (not going to fix it, will try to migrate to note 4 air command later)
  • no sound from left speaker (blame me for didnt notice that, my left ear has some problem, sorry) FIXED, temp solution here, ultimate fix will be included in the next update
  • failed to launch yTab Synapse Control 1.01 FIXED, please update to yTab-chagallwifi-1.01a-update
  • private mode not working FIXED, will be included in the next update
  • maildroid and skype not working


i have not tested all extra or stock features yet, especially for those apps/functions i don use but included in this rom for you guys only, so there may be some problems with certain apps or functions. kindly please report any problem so that i can take a look at that. thank you
