@TeamMex, I notice that there are two screen recorder, the native one and the oneplus version. My problem is they both record audio in mono. Is there a way to make it record in stereo?

Just tried the Yuki 4.14.238 July10 build and works fine. Is it possible to update the kernel without rebooting using FKM? Or is it better to reboot? Thanks for the update.

Im unsure about the changes made by the core team about the screen record also i dont use this function so i dont know

about the kernel to use the updated kernel you need to reboot so ...

I fixed the real-time shadow issue by going to derpfest telegram and someone said that installing the 32bit version of CODM will fix the shadow and it did. I hope this help others with this issue. Thanks

@TeamMex How do I check the changelog?

just did a clean flash, noticed that Google Play System update is stuck on 1 Jan 2021. Tried to update and reboot, which does so, but it will then reboot on itself again and rollback.

anyone has a workaround?

also cannot disable double tap to sleep. option is disabled but double tap still sends screen off.

Love this ROM❤️💯 and Been Using this as My Daily Driver... on Poco M2 Pro

The ONLY 3 BUGS that I found was that :
- Notifications getting cleared by itself (at random)
-Lockscreen Clock Alignment issue [for some Clocks]
- "Double Tap on Status Bar to sleep" is ENABLED BY DEFAULT ... And that leads to Accidental Screen Off's While Swiping down from the Notification Shade

The remaining are PERFECTO✌️💯...
No heating .. Good Battery Backup..

A Feature Request I would ask for is "SMART CHARGING" .

    Version Information
    Status: Beta
    Ouch :( after updating the Rom to June 21 update i got bootloop issue,. Now im back to zero which is flashing back to stock rom(MIUI Rom) then flash again the derpfest. :(

    I updated mine without problem using built-in derpest updater. Just reflash the latest derpest ROM or old one if latest is no good, you don't need to flash back to stock.

    In my case I always got bootloop issue in orangefox recovery if the charger is plugin (so weird), try unplugging it.

    Tried the latest Derpfest but for some reason safetynet fails and the device is not certified, I don't know why, clean flashed from PE+

    Latest update is also bootlooping for me on the Redmi logo; multiple clean flashes tried. Joyeuse.

    I've tried from PE+, HavocOS, Fluid and DerpFest and only DerpFest fails the certification and safetynet. I am on joyeuse.

    Have you fix bootloop?
    i tried many method to flash but i cant fix until now.

    Latest update is also bootlooping on the Redmi logo with multiple clean flashes tried. Joyeuse.

    No. I just went back to the previous build.

    I have joyeuse , No bootloops, Im using now Mi pilot android R Firmwared for joyeuse
    If u dont have EEA search for the firmware of your variant or tellme and i can make it for you if any R rom was released and u cant find the firmware.
    Updated using the updater and flashing it manually bot of them works


    CTS is also passing

    I hope they haven't changed the kernel because then it's not my problem anymore.
    Thanks, I'll reflash the kernel then. Do you have any recommendation for kernel config for gaming?
    As long as it's not pubg (I don't play pubg but if genshin impact, honkai impact and cod mobile all in maximum graphics settings without lag) you don't need to configure it in any different way.
    But if you still want to, change ZRAM to LZO-RLE if it doesn't come by default.
    Change the thermal for PUBG in franco kernel manager or similar.
    TCP to BBR2
    CAF CPU BOOST -> dinamic sttune boost to 20
    input boost to 80ms
    enable scheduler priority boost on input it can increase more the power in some games.
