Yes, if you turn off wifi and turn it on again it will be ok. Until it doesn't work again.

In my case, turning BT off solved the problem. Whenever I turn BT on, wifi speed drops dramatically and after a while it stops. This is also the case for mobile data. When BT is off, there is no problem.

Hello People,
is there a way to permanently disable OEM unlock, to not get "custom binary blocked by FRP lock" message on boot. I know about enabling OEM Unlock through developer settings. But now there is a problem... I need the phone for a kid with Family link account, which doesn't allow enabling developer settings. Is there any other way to get rid of this security option? Thanks!

I recently installed the firmware but I become fatal! It is very slow and all Google applications have stopped. I have restarted the phone to maybe solve the
problem but it is very very very slow to start. I'm very disappointed

What are you talking about this isn't a firmware it a costom ROM so the frp must be unlock before using it the only ROM that bypass frp is the official firmware from Samsung.

Thanks for this answer.

but, I was already asked this, 10 posts before, but no one answers. Is there any way to use this firmware if I can not access developer options?

thanks again.

In which ROM don't you get developer options? The official firmware or the custom ROM

    With the 'new' xda forum I lost the permission to modify the first message ...

    Lineage OS is a free, community built, aftermarket firmware distribution of Android 7 (Nougat), which is designed to increase performance and reliability over stock Android for your device.

    * Your warranty is... still valid?  
    * 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.  

    Lineage OS 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. You will need to provide your own Google Applications package (gapps). Lineage OS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

    All the source code for Lineage OS is available in the Lineage OS Github repo. And if you would like to contribute to Lineage OS, please visit our Gerrit Code Review. Your changelog is whatever was merged into gerrit.

    Installation instructions

    1. Download ROM and Optional: GApps.
    2. Copy ROM and Optional: GApps to internal storage.
    3. Optional: Perform a NANDroid backup of your current ROM (Optional but highly recommended).
    4. Wipe /data, /system and /cache.
    5. Flash ROM and Optional: GApps.
    Note: First boot can take some time. They may even loop a few times...

    And I began the cm13 there is 4 months and the cm14.1 since 1 month ^^

    All help to develop the rom is always really appreciated ;)
    It's only lineage updates as declain12345 said.

    I only launched a build without modifications except the lineage repo updated.
    I agree it's not fantastic but it's better than nothing :x
    I had 10 hours of time to make new build :)

    New build is out:


    -> May Security Patch

    P.S: J3 hasn't dead (for now) :D
    It's the worst bug ... I tried a lot of things to fix it ... I tried differents mali kernel modules, differents vendor drivers, differents hwcomposer, differents gralloc, a lot of build options, a lot of patches on the framebuffer driver, ...
    And the result is always the same :x
    Flickering on cm14.1 and no display on los15.1 ...

    The latest update is for the october security patch, a patch on the kernel to add a missing function to destroy a socket and some changes on ril to enable more functions.
    Maybe sim contacts works and the eap-sim protocol have more chances to work now the sim can communicate with an icc logical channel.
    FM flood log removed, missing selinux rules added.
