-one bug is common for me, its been unfixed since cm 13, is on plugging earphone jack, sound volume automatically keep increasing till end limit, even if you try lowering the sound volume, upon release button it again increase the valume. (3 logcat "earphone_bug(V).txt", "earphone_bug(W).txt" and "earphone_bug_2(W).txt" below)

-how do i fix is, first enable earphone status bar icon, then half plug earphone till it touch inside, wait one sec to appear headphone icon (icon that is not "mic on headphone") and wait one more sec, then fully push the jack in, if icon on status bar disappears or change with "mic on headphone" icon, immediately remove the jack and change orientation of phone (rotate to landscape/portrait) and do again, till icon remain still. (hope this understandable :P)

-and last.. yep alarm app working :P

Ps: plz let me know which logcat needed or what to be tested, i might help, also i did include reboot and shutdown logcat just for fun purpose :D

Thankyou Dev(s) for all your hard works :), i wish i had chance to work with you, but my interest is in developing games.
