Hello! Media sound (youtube, games, music, etc.) does not play when wired headphones (jack) is plugged, alarm and ring sounds does play. Any ideas how to fix this? Thanks!

The ROM is AFAIK stable, I always have testers to check if there are any major bugs before I release, so the users can have a great experience
Is good to see a android 10 rom in stable phase. I just want to know what are the bugs that this rom has, and if it has basic lockscreen functionalities (like, AOD, FOD, Unlock with screen off, etc.)

Sent from my Xiaomi Mi 9 Lite using XDA Labs

After the last update, terribly quiet ringtones, notifications and movie recording how to fix it. I installed it clean.

Can't disable immersive mode, the tile in qs not doing anything. Fingerprint feels slower and more inaccurate. Otherwise good rom, probs best for mi9lite. Likes to reboot and mic is mono not stereo like it was in miui. And aod is tied to screen brightness the option in lock screen settings isn't changing it.

Unable to add fingerprint. Latest version of May 28.


I had to add brightness to the maximum to react and I added a fingerprint. After turning off the maximum brightness, the fingerprint does not work as well

It works great only when the brightness is at maximum

With automatic brightness about halfway when the fingerprint is not working at all! :(

Exact same experience here.

Same here, tho I don't have to Set max. Brightness.

I have Set the minimal brightness Slider in the adaptive brightness Option to fill a third, which Kind of helped it a bit.

I've observed that the brightness is automatically decreased / Screen darkens quite a bit, as soon as the fingerprint senses an object to Analyse; a behaviour that might not have a positive effect regarding the recognition rate as Well.

Btw. I couldn't make Out a difference between Cyan/White for the pressed FOD Icon behaviour option yet (derpfest Lockscreen options), using Cyan here tho.

    1. DO NOT Report bugs if you're running a custom kernel or you installed Xposed
    2. 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.)
    3. If it is a random reboot, grab dmesg . (Do not bother getting a logcat unless you can get it just before the reboot. A logcat after a reboot is useless)
    4. If the problem disappears after running "setenforce 0" from a root shell, grab /data/misc/audit/audit.log
    5. Remember to provide as much info as possible. The more info you provide, the more likely that the bug will be solved. Please also do not report known issues.

    Hello, name is DarkAngelGR, I am currently developing for Xiaomi Mi 8 and now started working on pyxis. I don't have the device but I wanted to help with development cause I only saw on dev working on it and so I decided to help with development, now with @nysascape who made a kernel for the device that can be actually used I've started working on development. I am planning to buy pyxis in a few months but if you want me to get it faster you can always help me by donating to my PayPal. Hope everyone enjoys my work and don't forget to join my Telegram group where I will be more active, check it here

    Heyo everyone, it's me ya boi DarkAngelGR.

    As you all know I am developing for pyxis since February but released my first ROM built for pyxis around March/April since we didn't have a proper kernel source (huge thanks to nysa for making the kernel). Now it's June, currently maintaining Evolution X and DerpFest officially for pyxis while making a kernel for it as well.

    The reason of this post is to announce the start of the crowdfund so I can get pyxis. The price is around 230€ (ofc I will also tip in) in Greece for a second hand device. Why would I buy a second hand device you might say? Well it's obviously cause I can get the device ASAP while not paying 290-300 to get it brand new from a store/Chinese website and wait for weeks or months (Greek posts tend to be slow AF). After I get the device I can start working on selinux enforcing bring up for those that want the extra spicy security, and also try to bring up the device sources and build Android R for pyxis as well. The most important reason of the crowdfund is the time I waste on uploading test builds/waiting for the testers feedback which delays the development for pyxis and my main device dipper. I also want to take this opportunity to thank everyone for their support so far, both users and developers who have helped me a lot since I started working for pyxis. Just to flex, I also have the Pro tag on GitHub and I am a recognized developer on XDA as well ?.

    Disclaimer: Anonymous senders should know that they probably won't be able to get a refund in case the crowdfund is cancelled for whatever reason may arise.

    PayPal pool link: https://paypal.me/pools/c/8qpL1RHzm8

    PayPal.me link (in case you can't use the pool):
    Everyone donation send to my personal PayPal, will be added to the pool.

    Once again, I really want to thank everyone for the help so far and sorry the huge ass essay, I wanted to add some of my character in it (at least what I believe my character is, kinda serious with a tone of goofiness).
    New DerpFest update is out!!
