Hey guys. I want to downgrade from 16 to 15.1. Yes I know is be practice to stay updated but I absolutely don't like the new horizontal app switcher. I also don't think I want to install Lawnchain V2, Magisk, and the TaskSwicher module to get the old vertical app switcher back. Does anyone have any 15.1 builds for gts28vewifi they can spare me? Thanks.

    LineageOS is a free, community built, aftermarket firmware distribution of Android 8.1 (Oreo), which is designed to increase performance and reliability over stock Android for your device.

    LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

    All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review. You can also view the Changelog for a full list of changes & features.

    Instructions :
    • Download the latest build and gapps
    • Reboot to recovery
    • Flash the latest build and gapps
    • Reboot

    Reporting Bugs
    • DO NOT Report bugs if you're running a custom kernel or you installed Xposed
    • Grab a logcat right after the problem has occurred. (Please include at least a few pages of the log, not just the last few lines, unless you know what you're doing.)
    • If it is a random reboot, grab /proc/last_kmsg. (Do not bother getting a logcat unless you can get it just before the reboot. A logcat after a reboot is useless)
    • If the problem disappears after running "setenforce 0" from a root shell, grab /data/misc/audit/audit.log
    Remember to provide as much info as possible. The more info you provide, the more likely that the bug will be solved. Please also do not report known issues. Any bug not reported in the bug report format below may be ignored.

    Obviously not a lot has been ported to Lineage so please don't report issues like: "broken buttons backlight". That will be ported over soon (TM).
    Also you need custom TWRP build to install these packages, you can find link in the OP.

    BTW: You might have to force reboot after the gapps installation is complete as the unofficial installer is bit buggy ( you can do that by holding power, vol down ). Also it doesn't support addon.d so it doesn't persist when updating to next builds.
    [ cool stuff ]
    I just released 8.1 builds on my AFH.
    You can find them here ~ https://androidfilehost.com/?w=files&flid=234644
    I seem to have solved my battery problem by automatically disabling WiFi when the screen turns off.
    Need to run more tests to make sure, but last night the tablet lost 1-2% of battery.

    I automated the process by using "Automate". The free version is enough if you don't want to run anything else w/ it.


    Create a flow that looks like this:

    Make sure you give the app permissions by ticking the "access local network, internet and nearby devices" box, then installing the app it redirects you to.

    Also, you probably want to enable "Run on system startup" in settings. Careful, this can cause havoc if you have other, malicious flows.

    Run the flow and enjoy!

    I'll report back in a few days with more info about this.
    Q2. Any chances of having L15 nightly for T713 anytime soon?

    As soon as L15 source gets bit less ghetto and I finish up the SELinux.
