Last update (the one released in January 22) was reverted due to issues with audio in calls.
If you updated to it you may want to go back to the previous version if you want to make calls without any issues.

If you don't need/want to make and receive calls, you can still get the version released in January 22 here:

(remember that you don't have to flash the boot image with fixes in this version)
Hi, where can we check for updates/custom updates and etc?

    New update available for download. Sorry for the delay, i had planned to release this update on February, but lots of things happened.
    My Galaxy J2 got a short circuit so i won't be able to actively work on this anymore.

    Changelog:
    • Switched to stock Audio HAL. Fixes audio stops working and some microphone issues
    • Some OMX fixes, which fixed camera video recording
    • Switched to stock power profile
    • Switched to stock sensors library
    • Removed DOZE (Ambient Display)

    Workaround to connect to LTE (4G) networks (thanks to @cıyanogen):
    • Enable mobile data, 3G and reboot. Carrier is now available.
    • Enable LTE and reboot. The device will boot with 3G, and LTE connection should be available in around 10 seconds.
    • If you reboot or turn off the device, the carrier is not available. Enable 3G in settings and reboot.

    New update available. The apps crash problem is now fixed and the Android Security Patch was updated to October 5, 2019.

    I wanted to release this update yesterday, but i wasn't able to do it because my Ubuntu installation almost broke when i was upgrading to the latest version. Luckily, i managed to restore it.
