Hi.
In my case, it's more like if some of the sound passes from the microphone to the ear speaker. It doesn't happen if I use the loudspeaker during the call. It's easy to reproduce, in my case, by scratching the mic while on a call

it can be solved. as far as I understand it is related to the kernel.

Yes, the kernel is also my first guess.
Do you also experience the GPS problem (only GLONASS and GPS signals are detected) and the pedometer not working?
Thanks

It's the same for me. I can't hear my voice but just some sounds like scratching the microphone. In the last PE Plus with Android 11 it wasn't present. Just with the new Android 12. (I'm with the Plus edition)

I also have the same problem of audio return from the microphone, very annoying during calls, also I only have GPS and GLONAS signals.
Will the audio problem be solved? otherwise I will have to revert back to the original firmware.

Welcome in the club!
to solve I flashed the A11 PE + (latest build available - discontinued)
no one seems to understand that maybe this bug is about A12, or some kernel..but I don't know about it
I just know that I have flashed everything new with A12 for our MI8..and they all have this issue

I had same issue with microphone. Brand new telephone (old new stock) and I did notice that gcam (MGC_8.1.101_A9_GV1zfix_MGC) had problem with autofocus.
I installed last 11+ version and telephone is working perfect. No more mic problem, photos are great, everything works like it is suppose to. Waiting for fixed 12+...

I installed the ROM like about 3 months ago.
It worked perfectly until a few days ago, that everything is becoming slow and non fluent.

Specially when unlocking with the fingerprint or using the camera there's quite a lot of lag.

Of course, I've tried rebooting with no luck and I'm using the latest version (SP2A.220405.004
PixelExperience_dipper-12.1-20220415-1554-OFFICIAL).

Any ideas/help?

GPS problems should be an easy fix.
in your /system/etc/gps_debug.conf file change XTRA_SERVER entries to LONGTERM_PSDS_SERVER
Hi!
It worked!
Thanks a lot!
Ps. In my case, I don't know why, I couldn't edit the file using a root explorer. Had to copy the file to internal memory, then edit file. After that I copied the file back to the original folder. To change permissions of the file to 644, I had to use Orangefox recovery. No root explorer could change file permissions!

I have the same problem sometimes when i try to post on instagram (i have to force stop the app). Or when i open Filmic Pro and from portrait i go to landscape. So i have to put the phone before in landscape and then i have to open the app.

Generally this Android 12 releases are very buggy.
The latest Android 11 releases were perfect!

Also having issues with Hotspot. The whole phone starts to get sluggish when someone is connected. Also can't turn it off manually or the settings app will crash. Gotta reboot or wait for it to automatically turn it off if noone is connected.

    Hello guys!

    I'm sending this message to tell you my impressions of the new Rom update. I was really excited about the update and the results, so I think it's worth sharing.

    In short, I'm really enjoying it!

    I was still using the latest version of Android 11 and I waited until that moment for version 12 to become more mature, I followed the evolution of this version and I am very satisfied!

    I'll put here my impressions of this change from version 11 to 12:

    - In preparation for the installation, I wiped all partitions, used the side-load through TWRP and everything went smoothly. After installation, PixelExperience Recovery was installed automatically (Senatore tip).
    - Battery life: Improved a little, I understand that the battery itself is not new, but I already liked it because it was better than before.
    - System fluidity: Excellent! Fluid system, no crashes and all applications working very well
    - Apps: With the guidance of other comments here on the forum, right after installation, I cleared cache and storage of Apps, disabled the ones I don't use and everything has been working very well
    - Plus version additions: Excellent! I don't know why these extras are not included, the OS becomes more agile and smart. Great insight from the developers. I just had a hard time finding the option to turn on the flashlight with the side button, in the settings search I couldn't find it, I had to search within each category.
    - General phone usage: All praise! All in order and responding very well. I haven't tested NFC, so it's up to those who use it to test.

    Once again, my thanks to everyone on the forum, you guys send valuable tips that help everyone with Rom usage and troubleshooting, thank you very much!
    The Rom team, especially Mr. Senatore, for the fine work in getting this device to work so well with updated software. Thank you for your patience, work and interest in this continuation of this excellent device.

    Thank you and congratulations!

    April update up
    Changelog
    **Device Specific Changes:**
    - Etude kernel: Op.11 No.4
    * Linux 4.9.267
    * some upstream fixes of cpufreq_stats
    * fixed an issue where the frequency of big CPU cores is locked to a maximum of 1286MHz; the frequency of the big cluster is supposed to be restricted under 1286MHz if you battery is at or below 10%, as part of Qualcomm's thermal mitigation, but on previous versions, the frequency restriction was not removed after the phone is charged above 10%
    * default to suspend to RAM instead of s2idle (suspend to idle) for around a 25% reduction of idle battery drain
    * DO NOT use a third party kernel without proper support for Pixel thermal hal
    - Adjusted thermal configs to delay CPU frequency drop and smoothen the thermal throttling curve
    - Implemented dynamic thermal profile to work with Pixel thermal engine
    * the option is accessible under Settings/Battery/Optimization profiles (in case you are wondering, they had no effect on PE11 before this change)
    * thermal configs are dynamically loaded on a per-app basis
    * only the gaming profile is available besides the default profile, because other use cases are covered well enough by the default profile
    * the gaming profile maintains CPU frequency at even higher temperature compared the default profile
    * surface temperatures are measured by an infrared thermometer with matching emissivity to ensure they stay below the allowed maximum values of continuously held electronic devices in IEC 60950-1 (2005) standard
    * thermal profile is NOT a replacement for proper cooling. If you want better performance, you should cool your device. - Eliminated all SELinux neverallows and cleaned up unneeded or broken sepolicy
    * the latest Riru installation should work now. Note that if you use any mods like this, you will not receive support from me
    - Updated telephony blobs from pyxis 21.3.31 to fix random qtibus crashes in the background
    - Went back to Secure Element 1.0 to work with the updated blobs
    - Stopped enforcing s2idle from userspace init script so the kernel can suspend to RAM for better idle battery drain
    - Cleaned some unused config overlays
    **ROM update highlights:**
    - April security update
    - Fixed the issue of weather information not showing up in "At a glance" on the home screen of Pixel Launcher
    - Improved Face Unlock. The issue of front camera being occupied should happen less frequently. Let me know if you still encounter it - Devices will only use dark boot animation from now on
    - Translation updates

    Hi,
    I've also got a problem with the sound during phone calls (like someone above already mentioned), regarding the latest PE 12 release for Xiaomi mi8 dipper.

    If I'm on call and put the phone to my ear, I hear some echo with almost no delay of what I say in the speaker. It feels like I say "S" and someone aplifies this and "SZ" comes into my ear. At the beginning, I hardly noticed it, but sometimes in the middle of the call the feedback howl randomly gets very bad so my ear hurts after the "squuueeeek pffff". After that, it takes 2-3 seconds and the audio is just "szzzzz" with little feedback and I can talk normally. I've experienced the loud howl 4 times now, so I suspect a bug (driver , audio mixel level?) since the latest release.

    I'd appreciate if you could have a look at it.
    Thank you
    yup I confirm the issue is present on my device as well, will start investigate asap
    thanks everyone for reporting :)
