I think I found it. This causes 17192 wakeups over night somehow. Resulting in 1,8% idle battery drain which is a bit bad...

    * I'm not responsible for bricked devices, dead SD cards, thermonuclear war, or you getting fired because the alarm app failed (like it did for me...).
    * Please do some research if you have any concerns about features included in the products you find here before flashing it!
    * YOU are choosing to make these modifications, and if you point the finger at me for messing up your device, I will laugh at you.
    * Your warranty will be void if you tamper with any part of your device / software.
    * Same statement for XDA.

    LineageOS is a free, community built, aftermarket firmware distribution of Android 10 (Q), 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.

    Hey, I wanted to know if there is a date scheduled for an update of this ROM ? It looks pretty good but I'm waiting for an update to install it.

    An important exam beyond your imagination is coming up and I don't have server to build rom. I'll build as soon as I make free time.
    I might be slow to respond due incoming very important high education exam. But I'll be active on my free time.
    Changelogs :
    Public Beta 2 - 10/01/2021
    • Fix WIFI on some models.
    Public Beta 1 - 10/01/2021 :
    • First beta release.
    No, and youll never be able to have wifi on and hotspot on concurrently or at the same time, its virtually impossible to do that on any device. Im saying, if i turn hotspot on, connect another device then turn hotspot off and try to turn wifi back on, it will not connect. It connects then disconnects and continues this cycle even after reboot. The main concern is t mobile sim cards not having any sound through the earpiece but does work with speakerphone, att sim cards work fine. Ive tested 3 tmobile sims with the same results. I have currently moved back to stock due to this issue with sim cards because i use dual sim for my company, one sim is att the other tmobile and i need them both. Mic volume is also very low so doing videos and conference calls were null. This is a great rom and am proud of your work. As with any "test" build, there will be bugs. Ill flash back sometime this weekend and pull logs, but something that really needs looking into is updating. When los is already installed and an update los build or even the same build is flashed, dfe and format data must take place for it to boot properly then you can run the restore but if the build is too far off from the backup, it wont boot either. This makes it to where every build must be a fresh install.
    Have you ever heard of "soft ap". Did you use any sdm or sm devices ? Did you try wifi sharing feature on stock rom? It is possible and many devices benefit it. Documentation for you to read: https://source.android.com/devices/tech/connect/wifi-sta-ap-concurrency
    About data issue; I've shared link for it in main post. Samsung's skeymaster does not like "dirty" data partition. Either wipe your whole data partition or flash that zip to preserve your files.
