Rom works fine but I had to reboot it twice since I installed it. There's an issue that when you're watching video (for example on YouTube) suddenly screen freezes. Audio is still played but tabled is irresponsible, only power button works (you can turn on and off display) but there is no way to unfreeze screen other than reboot. What logs should I provide?

Stable One

Andi, Clean flashed this with complete wipe data and format data.ROM takes some time to stable on P3100.
But from yesterday everything works excellent. Mostly All ROMs on P3100 have problem of call drop including CM13.
This is excellent one. From last two days there is not a single Signall dropout even after heavy usage and 5-6 apps open simultaneously.
First is Format data on P3100 otherwise this problem of signal drop occurs and it leads to reboot. so problem solved.
Thanks Andi once again.Only request is to do the same with Omni 5.1 whenever you are free. Because P3100 was very popular in india and many uses as daily usage. In Indian addition Omni works better than other roms.
So keep it up. Enjoy your life. And yes you bring smile to lots of Tab 2 users. God gives you strength and blessings.

I couldn't find out if it's just me or does Omni 4.4.4 18012017 not support f2fs : on booting after a clean flash and open gapps 4.4 Pico, it says encryption. unsuccessful reset tab? Obviously I DID NOT reset it and have booted into recovery.

Also , f2fs is a filesystem for friendlier (less wear, auto fstrim?) and faster read/writes on eMMC right? is it needed from an aged tablet point of view or will ext4 lead to no observable difference ?

    I talked to jiangyi and i need to fix the broken keyboard without cherry-picking 
    a commit... 
    the commit i used to fix it is not merged into omni´s github yet... :(
    - but i found another way to fix it :)
    [*]Kernel No-OC by default
    [*]No Multi-Window / Split-view
    [*]"CONFIG_KEYBOARD_SEC_DOCK" disabled in kernel-config ; this
    fixes the broken keyboard too (this bug is kernel related)
    [B][U][COLOR="Red"]Please test this build and report back! 
    This is important to get official support![/COLOR][/U][/B]

    Added Code Review wich not got merged yet
    [B][U][WIP] Multi-window[/U][/B]
    This is a big work in progress, which currently has some bugs,
    but begins to look okay.
    You can already multitask a little bit, by using the
    app switcher and long-pressing an icon, then select "Add to
    Split View".
    Last window touched gets the key focus.

    [B][U]input: Add workaround for broken hardware keyboard support[/U][/B]
    New unofficial for P3110 uploaded already,
    P3100 still compileing - ready after sleep.

    • Upstram OmniRom changes (Android 4.4.4 now :) )
    • some kernel changes, hope fixed Battery-Drain (reported on some devices, not happened to everyone)
    • Boeffla-Sound: Engine 1.6.6 added to kernel
    • all good stuff like every time: floating Apps, AppCircleSidebar, On the go, Batterysafer, Animationcontroll, WhiteKat UI

    Sent from my GT-P3100 using XDA Free mobile app
    Sure, i like to see that there are many user likeing my work and are thanksfull all the time.

    I got a lot of sleepless nights in the past view month and can not manage that much work anymore.

    If i like to work on L i do - if i don't like, i won't.
    if people ask for ETAs all the time, then i try to compile for myself only and do not share anything! Maybe.a screenshot, but thats it.

    Also please all together, stop writeing PM's asking for L!
