New version installed on A72.
Beautiful ROM and it gets better with every new version!
The proximity sensor does a great job of turning the screen off and on during a call. The automatic screen brightness also works well, it doesn't seem to constantly change.
The only downside I noticed is that you can't add a fingerprint to unlock the screen. The addition process starts, the screen reacts to the touch of the finger, the green circle under the finger lights up, but no fingerprint is recorded, the sensor does not vibrate even once to raise the finger further and lower the other part.
Great ROM!
Hmmmmm is night light on by any chance?

Hi, I've just installed this rom to test it out and it has been working great.

My only issue is with setting up GCam properly. Telegram is blocked in my country and I'm trying to figure out a stable GCam version with a good config.

Can anyone guide me as to what is (are) the stable gcam versions and configs that work with this rom?

Thanks

Hello, I noticed that the always-on display doesn't adjust its brightness automatically (like samsung's AOD auto-brightness implementation).

Is this something that can be worked on the firmware side?

Right now, the always-on display brightness is set to the value that the screen brightness was before it was turned off. So if I turn the screen off at 30% brightness, AOD will set brightness to 30%. Subsequent lighting condition changes does not affect the AOD brightness.

However, if I trigger the fingerprint touch on AOD so it lights up but doesn't register fingerprint, the AOD brightness jumps up (maybe to 100%?) and stays there, even after fingerprint trigger goes away.

The opposite isn't true. If I cover the proximity sensor and touch the fingerprint again on AOD, the AOD brightness doesn't go down.

Update on this.

I'm able to reproduce this behavior like so:

1. unlock phone
2. set brightness to manual, and lower the brightness
3. lock phone
4. the AOD respects the brightness set in previous steps
5. quickly tap the FOD (sometimes the bug happens on first try, other times on the third try)
6. the AOD brightness jumps up and remains at full brightness
7. press the power button to turn on the lock screen
8. pull down the notification shade and try to change the brightness
9. the brightness doesn't change with the slider (set it to low to observe next behaviour)
10. unlock phone, brightness jumps up to full even if we had set brightness to low in previous step
11. after unlocking, changing the brightness works as intended

Im aware of this and am working on a fix.

I think I was rushing to judge the ROM in battery, I think I may have to personalize it more and test it for more time. In real I settled for disabling AOD, (in normal use it should consume <1% per hour), but in this ROM I feel it consume like >2%. And settled for disabling the screen turning on while I pick the phone (Don't know the correct term, I use in arabic), because screen was turning on weirdly multiple times in the car. (Till now I have completed 3 days, which are just a little)

I have been using this Rom in my a72 for 3 days. The alignment of the characters on the keypad is not correct (not perfectly centered). The letters should be perfectly centered. At times, the screen brightness becomes maximum after fingerprint unlock. Thanks for the developer. This Rom is getting better in every update.

I'm not meaning offence, but I mean if you will focus on such a details for a custom ROMs, then I advice you to stick in the stock ROM. Custom ROMs are probable for way way more bugs than this, usually you have to dispense one big feature. I miss most of the things when I see the main things just working well. Anyway I may just return to stock because of the battery drain😄

Ok, I've amended the rom more, some optimizations, and turned off AOD, the rom started giving me a very good battery time. 32 hrs with no charging, 30% battery left, with obviously minimal usage + using battery saver in sleeping time. I turn off location / NFC when I finish my need of them. I think it's close to stock in battery draining.

Announcement!

A52 4G and A72 are now officially supported by Pixel Experience!

From now on new builds will be released on the Pixel Experience website.

What are the differences between the official and unofficial versions?
-The official ones support OTA-updates, meaning you can just update from the Settings app (Settings->System->Updater)

How do I update to the official version?
Just download the newest official builds from the Pixel Experience website and flash them using TWRP or Orangefox or Pixel Experience recovery. After that you should be able to update using the Updater in the Settings app.

Downloads
A52 4G: download.pixelexperience.org | wiki.pixelexperience.org
A72: download.pixelexperience.org | wiki.pixelexperience.org

Great news for official support.
Quick newbie question. If i had reverted to stock, to install this rom again, what do i have to do?
I know that i have to install the custom recovery again, but after installing it do i have to flash service disabler again, or do i have only to format data, then flash the rom?

    You will have to clean flash (format data) and flash this update. Flashing without formatting data will result in some features being broken and no support will be provided to you, so please make sure to clean flash.

    What is this?
    PixelExperience is an AOSP based ROM, with Google apps included and all Pixel goodies (launcher, wallpapers, icons, fonts, boot animation)

    Our mission is to offer the maximum possible stability and security, along with essential and useful features for the proper functioning of the device

    Based on Android 13​


    Supported devices!
    Both variations of A52 4G and A72 (A525F and A525M and A725F and A725M) are supported, but only A525F (6/128 variant) is well tested as I have this device. A72 also has lower support as I do not own one.
