oh well ... small cleaning has been performed due to Forum Rules incompatibility with some posts
2. Member conduct.

2.1 Language: XDA is a worldwide community. As a result, what may be OK to say in your part of the world, may not be OK elsewhere. Please don't direct profanity, sexually explicit language or other offensive content toward Members or their work. Conversely, while reading posts from other members, remember that the word you find offensive may not be offensive to the writer. Tolerance is a two-way street.

2.2 Nudity: XDA is used by people of all ages, including minors. It is unacceptable to post nude or pornographic imagery, which includes the exposure of male or female genitalia and / or female breasts.

2.3 Flaming / Lack of respect: XDA is about sharing and this does not involve virtual yelling (flaming) or rudeness. Flaming or posting with a lack of respect is unacceptable. Treat new members in the manner in which you would like to have been treated when you were a new member. When dealing with any member, provide them with guidance, advice and instructions when you can, showing them respect and courtesy. Never post in a demanding, argumentative, disrespectful or self-righteous manner.

2.4 Personal attacks, racial, political and / or religious discussions: XDA is a discussion forum about certain mobile phones. Mobile phones are not racial, political, religious or personally offensive and therefore, none of these types of discussions are permitted on XDA.

2.5 All members are expected to read and adhere to the XDA rules.
please keep it civil guys, is just a phone ... Have fun and enjoy the development!
Thanks !

Hi. I have been using Los for about 2 months with regular updates. I didn't face much problem until about a week ago when Volte stopped working. I can access internet with the 4g network but cannot make or receive calls and sms. All the settings are where it should be. I don't know what the underlying problem is. Please help.

     * Your warranty is now void.
     * I am not responsible for bricked devices, dead SD cards,
     * thermonuclear war, or you getting fired because the alarm app failed. Please
     * do some research if you have any concerns about features included in this ROM
     * 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.
    LineageOS is based on the Android Open Source Project and CyanogenMod with extra contributions from many people within the Android community. All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS please visit Gerrit Code Review.

    What's working
    • Mostly everything except for those mentioned in Not working list.
    What's not working
    • Permissive SELinux
    • Maybe more ROM specific bugs
    Installation instructions
    • Get ROM and GApps and put it in phone.
    • Boot to recovery mode.
    • Do a factory reset. If you are coming from some previous version of LineageOS itself then this step is optional.
    • Flash ROM, then flash GApps.
    • Reboot. First boot will take time.

    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
    Any bug not reported in the bug report format below may be ignored.
    Phone Informations
    * LineageOS version
    * Gapps version
    What you did:
    * Wipe data: y/n
    * Upgrade from previous official cm build: y/n
    * Restore with titanium backup: y/n
    You're using (if yes write which one) :
    * Task killer
    * Phone cleaner / Battery enhancer apps
    * Non-stock kernel
    * Modified kernel settings
    * Other mods
    Bug info:
    * Last version it worked on
    * Repro steps
