Hello, I successfully installed the rom. Thanks to the @Developer for providing such a cool rom. But, I'm facing a problem. The problem is, any videos of Instagram, Facebook, WhatsApp's post or story is not playing. Anyone else facing the same problem? How can I fix this issue? If anyone knows please tell me. Thanks

Hello i'm more awkward than regardless of loading a custom ROM into my phone but i'm interested in the following. I currently have a Pixel5 OS in my phone that is loaded with orangefox. I would like to download OS Lineage 18.1. As far as I understand, I should load MIUI 12.0.3 (QJGEUXM) first, or I can load this OS Lineage 18.1 directly with orangefox without loading MIUI 12.0.3 (QJGEUXM). Can anyone tell me how to do this. Sorry for my English.

    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.

    Same statement for XDA.

    LineageOS is a free, community built, aftermarket firmware distribution of Android 9 (pie), 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.

    for me, it makes sense. for now, no official opengapps 11 available and my experience with nitrogenos and nikgapps offers problems for daily usage.

    Depends on why you want to get rid of MIUI, personally it's to avoid Google's bloat and run ( mostly ) free and open source software, if tommorow a linux distro shipped with Microsoft Edge or whatever I would make sure to not touch it, I guess that's why people are into LOS, but hey I'm sure many people don't care tho, if it wasn't a thing nobody would put instructions to install gapps after all
    From what I have seen until now, the XDA threads are here because its a requirement to create one. However, the real support is done in the telegram channels (like https://t.me/pocox3globalofficial).
    I use this LineageOS rom as a daily driver. I have only minor complaints. The APN needs to be set on each reboot, but I do not reboot often. And (for me) its cumbersome to switch between different bluetooth speakers. But its running stable and I am happy with the battery life. I am using the gcam but have not played with the stock camera before, so I can not compare. See this thread for a comparison: https://forum.xda-developers.com/t/gcam-for-poco-x3.4164397
    You can also install gcam on MIUI and directly compare if you like before switching to a custom rom.

    Edit: Got best results with recent version from Nikita. But that might change quickly, just follow the thread or Telegram channel. Currently I have:
