Hello, firmware is great, been using it for a month now. Noticed a bug in the latest version: when calling through the 2nd sim, the microphone does not work and you can not hear the other party; if you turn off the sim in the settings, then you can not turn it back on, it only turns on after rebooting. And if possible, add the function of selecting sims for internet from the curtain, now I switch sims via settings. Many thanks again for your efforts. My device: A525F 4/128. Firmware version: v3. Updated dirty. (I use translator, don't speak english myself)

**************************
Здравствуйте, прошивка отличная, пользуюсь уже месяц. Заметил ошибку в последней версии: при звонке через 2-ю симку не работает микрофон и собеседника не слышно; Если в настройках отключить симку, то обратно включить нельзя, включается только после перезагрузки. И если есть возможность, добавьте из шторки функцию выбора симки для интернета, сейчас переключаю симки через настройки. Еще раз большое спасибо за ваши усилия. Мой аппарат: A525F 4/128. Версия прошивки: v3. Обновлено грязно. (я пользуюсь переводчиком, сам не говорю по-английски)
@MrFox6
Welcome to XDA. I hope you'll always find and get the support you require.

As courtesy I've translated your above post. Already about 3 weeks ago, my esteemed team mate @Badger50 translated another post of you here. This is just a friendly reminder that English is the mandatory language! With reference to rule no. 4 of the XDA Forum Rules, please post in English or add at least an English translation to your Russian posts.
4. Use the English language.

We understand that with all the different nationalities, not everyone speaks English well, but please try. If you're really unable to post in English, use an online translator. You're free to include your original message in your own language, below the English translation. (This rule covers your posts, profile entries and signature). You could try :- https://translate.google.com/ or https://www.babelfish.com/ or use one of your choice.
And two additional remarks:
  1. You might want to consider to attach thumbnails instead of full images in future in order to gain a better reading and scrolling experience.
  2. In your screenshoot you distribute the two IMEI's of your device. IMEI's can be misused for evil or even criminal purposes. Consider to replace your screenshot by one, in which the IMEI's are pixeled or covered.

Thanks for your cooperation!
Regards

A72: I am using V2 of your rom in my A72 4g. Downlod link is for V2. Proximity sensor is not working properly: If you take it close to the ear, the screen turns off, but if you take it away, it does not turn on. Fingerprint sensor is not working as well. Another thing: I don't like the down arrow key below the keyboard. Is there any option to remove it?

I confirm the same behavior on my A72 for the screen during the call.
The screen turns off when I hold it to my ear, but then if I move it away from my ear it stays off until the call is ended.
Rom version is marked v2 from 22.05.2022.
My banking app Is working, but cant log in on Pokemon Go. Non rooted phone.

Proximity sensor is working as intended tbh i dont think ill add detection for taking phone away from face, as i dont really know how to fix, and proximity sensor works as is. Fingerprint is broken on a72 and i dont think ill be able to fix that till i get an a72, which i dont see happening. @raicevic pinging you as it pertains to you too.

I cannot help but notice that the Latest LOS has encryption enabled - might Pixel Experience Plus encrytion work some day, or is there a general incompatibilty with the A52?

Thanks - I'm still on S7 with encryption disabled (LOS doesn't enabled it), but swore my next 3rd party enabled mobile phone should be encryped.

Encryption is still buggy and doesnt work for everyone even on lineage os yet. I tested a build with it, and it was not booting pe, so I have not included it in this update, but I do plan to add encryption support.

Sounds great, thanks.

When you add encryption (or when moving from LOS w/o encryption to LOS w/ encryption) by updating the OS, will the data partition be encryped in-place - i.e. will the encryption be seamless?

I have a question why the developers of the system do not put in the Bluetooth settings the option to connect to the laptop with the help of link to windows, ie to put the option in the Bluetooth settings link to windows like all Samsung devices?

    Does anyone experience more battery drain comparing with stock?
    I'm using experience plus, for the a72, the battery is lasting longer than in the factory rom.

    * Your warranty is now void.
    * I am not responsible for bricked devices, dead SD cards,
    * thermonuclear war, or you getting fired because the alarm app failed. Please
    * do some research if you have any concerns about features included in this ROM

    */

    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.
