Releasing EKManager version 1.1.0 with some changes

Changelog:
-> Introduce jni for parsing device info to properly parse it. In java its hard to implement.
-> Fix custom flashlight value not storing after changing menu. (Thanks @CyberDroid1)
-> Fix profile menu editor not opening and crashing. (Thanks @d3_d4n)

Bugs: custom controls menu work but the "editing part" is buggy.

Notes:
Jni is C/C++ on java. it is used to run native binaries with java interface.

Download here or you can update using EKM internal updater.

As usual report bugs to @roynatech

Fact of the day:
Our current kernel uses Linux version 4.4.y which started in 2016 and will end in 2022.
We have 4 months left before we stop receiving bug fixes from Linux.

OFFICIAL FEATURES OF EUREKA R8.0

→ Upstream Linux Kernel Version from 4.4.277 to 4.4.288

→ Added ondemandplus CPU governor.

→ Added BFQ and ZEN v2 I/O schedulers.

→ Added a new backlight brightness controller. [Feature can be used when new EKM app is released] [Experimental]

→ "Samsung A10 1.2A input charging current" feature has been hardcoded in kernel.

→ Nuked CPU quiet and reverted back to Exynos Hotplug. It should fix issue of cores randomly turning off.

→ Fixed GPU frequency being limited to 1100 MHz after being throttled (v2.0).

→ Some optimizations for better FS performance for EXT4 file-system.

→ Fixed non-detection of some gamepad controllers (such as chinese ones).

→ Patched kernel for android 12 (S).

→ Some other minor optimizations.
