I think I found a bug in the lock screen.

If you disable "show device controls" in combination with "show all notifications content", you can use the device controls (e.g. reboot device, disable wifi, etc) while the screen is locked.

This has been bothering me for a while. Has anyone figured out how to set the minimum level for Adaptive Brightness? It goes down to around 15% when I'm in a dark environment and I can't see a thing. I have changed it at least 100 times, and it still goes down to that level. Cheers

The "show device controls" toggle is supposed to show or hide "device controls" menu, like chromecast devices, Google Home devices, etc., on lockscreen. It has nothing to do with QS tiles.

This is a thing that I cannot make everyone happy. Some complain the minimum brightness in adaptive brightness is too high, and some say it's too low.

Theoretically, if you manually adjust the brightness, the system will try to take the adjustment into account and fit your "user entered" point into the brightness curve. It will remember the adjustment until next reboot. However, if somehow it does not work for you, I can't do anything about it.

If you really want to fix it once for all, you can bump the values in this array right here:
and then build from source again.

Ok. But if I disable the notifications, it also locks the usage of the quick controls. Shouldn't these be two separate things. I want to be able to see notifications, but I don't want anyone to turn off my phone or my wifi without authentication

I think you're right, that's exactly how it works, I just couldn't figure out the pattern. It works for some time, then it's always reset. A think the key here is that it resets itself after reboot. It probably shouldn't do that. Your individual user preferences don't change because you reboot your phone. If someone wants to reset it, they can do that through settings. What do you think?

No. I believe it definitely should reset after reboot. What if you mis-operated and accidentally set an incorrect user point? What if the user points accumulate over time, and the curve goes out of control?

The android system is designed to be never rebooted unless there is an update, so it is natural to let the brightness curve reset after reboot.

What you describe is an edge case really. To most users it'll never happen. But should that be the case, one can go into settings and reset Adaptive Brightness manually

Screenshot_20220616-073344_Device Health Services.png


The problem with resetting after reboot is that it takes a good week or two for a user to configure every brightness level to their liking. With monthly updates, this means that by the time they're all set, an update comes and they get reset. In hindsight, the issue is not that the minimum is low. It could be anything really, if users could then adjust the brightness values to what they want. The real issue is that by resetting at reboot, a single returning value is forced on every user. And that never worked in human history because we are all humans and our preferences differ ;)

Completely unrelated to the brightness topic, I think I have found two bugs:
* "Power menu > Lockdown" Locks down the phone (as expected) and the fingerprint sensor stops working entirely. You can only unlock the phone using pin. A reboot fixes it.
* Certain apps and UI elements can't recover from "Extreme Power Saving" mode. That includes the built-in Google weather widget and Google Assistant. Both of which only come back to life after reboot.

Of course it's possible that both of these only happen on my phone...

Well Adaptive Brightness was introduced in android pie, and it has been like this since then. I can't really change the behavior because that would be against "Pixel"'s experience. However, you can probably raise this issue to Google and see what they're gonna do with it.

1. A reboot is not required. I just tried it on my polaris, and you only need to use pin to unlock once. Subsequent unlocks are fine with fingerprint. This seems to be the intended behavior (because internally, the security level of fingerprint is lower than pin, so perhaps "Lockdown" wants you to use the highest level of authentication once), but I'll check with other devs.

2. I'll let jhenrique09 know.

Just to be very clear about it, this isn't personal and it isn't against the work you do. I really appreciate all that. It's more a theoretical "argument" than anything, for an overall better user experience. The fact that a mammoth company does something a certain way doesn't necessarily make it right or correct in my personal opinion. I agree with you 100% though that it wouldn't be "Pixel" experience if you changed that. That's a valid point.

ps: Instead of building from source each month, I have ended up solving this with Tasker.

1, You're right, although I had to unlock with pin twice, not once. But no biggie, if it doesn't need a reboot.
2, Thanks!

Perhaps this is just my problem, but for the second time I've been observing that the cores are being lifted. first small x4, then large at a frequency of 2803 mhz. The first time the flashing helped, now it does not help. What's this?

And because of that battery drain so fast and the phone is so hot.

Actually, authentication is required before changing anything in the "Internet" tile, so other people will not be able to turn off your WiFi.

I don't know, and it never happened to me. It could be anything. Take logs next time it happens.

How can i take logs on PE12? And it happens all the time. In real time. It doesn't stop at second.
Are you sure you are not using any 3rd party kernel or modules? The CPU should not lock to a certain frequency in stock PE.

To take logs, enable USB debugging in developer options, connect your phone to a computer, agree to the prompt, and
Code:
adb logcat > pe_cpu_freq_stuck.log

Do it when the frequency issue appears. Press "Ctrl + C" to stop the capture.

Yes, I've never used any 3rd kernel, all was stock. Hope this will help you. Don't know why but i can't attach here. Send you via message.

Nope. I can turn off everything. Wifi, mobile data, the phone... All without any authentication being required.
The only way it asks for authentication is if I set the notifications to not show up on the lock screen.

    PE for Mi Mix 2S is dead, since there is no support for Android 14.

    Instead, I just switched to Lineage 21.
    Follow the steps:
    - Update to a newer vendor firmware version
    - Installation
    that brings all(?) the features that the Plus version of PE also had, so there is no loss in functionality for me.

    bye bye, PE, it was a good time, but now it's over.

    - If your partition is not encrypted, your phone may not boot properly after flashing the update. This is because the zram optimizations changes fstab, so the previous fstab patched by the "disable forced encryption patch" you had on your phone is overwritten. Therefore, you need to flash the patch to disable forced encryption again. If you use OrangeFox, you can also flash the full package, because OrangeFox will automatically patch your phone after flashing full package.

    2020/01/31 - 1907
    * Fixed double tap to wake on Mix 2s with ebbg screens
    * Reduced LED blinking frequency under low battery, without interfering with notification LED
    Note: PE has been improving their OTA updater recently and some work is still in progress. Clicking "install" in the updater may cause install error for now. You might need to manually flash the incremental package in recovery.
    Update: Updater is only supposed to work with encrypted device. If your phone is not encrypted (OrangeFox disables forced encryption by default), you need permissive SELinux to be able to use the updater.

    Here is a quick way to change SELinux status if you have root:
    Code:
    abd shell
    su
    setenforce 0
    getenforce
    You should then see "Permissive" being printed in the shell.

    - PE recovery is REQUIRED
    * DO NOT use any other recovery
    * Partition scheme has been switched to retrofit dynamic partitioning because polaris is running out of system partition space. No actual re-partition is involved. Instead, the physical system and vendor partition is mapped together to form a logical "super" partition. The size of super partition equals the sum of the physical system and vendor partitions. After that, logical system and vendor partitions are created on top of this super partition. In this way, we are essentially redistributing space between the physical system and vendor partition to accommodate for the increase in size of system libraries and prebuilt apps.
    * The firmware is included with a different keymaster.img from perseus. DO NOT flash your own firmware.
    * To switch to other ROMs, format data in PE recovery first, and then install another recovery. You may need to re-flash the required firmware, if the ROM you are going to flash does not include one.
    - You can dirty flash from the previous PE 13 build. You can dirty flash PE 13 Plus on top of the regular PE 13.
    - You cannot upgrade from android 12 builds. Formatting data is required.

    ==============================
    Old guide for android 12 builds:

    - Formatting data with PE recovery is REQUIRED for clean flash
    * DO NOT use any other recovery
    * The firmware is included with a different keymaster.img from perseus. DO NOT flash your own firmware.
    * Keymaster is bumped to 4.0 for encryption, and cust partition is mounted as /metadata. You WILL NOT be able to boot TWRP on PE 12.1. OrangeFox R11.1_1 or newer can boot but is not capable of decrypting the data partition.
    * To switch to other ROMs, format data in PE recovery first, and then install another recovery. You may need to re-flash the required firmware, if the ROM you are going to flash does not include one.
    - You can dirty flash from my previous PE 12 or 12.1 builds. You can dirty flash the Plus edition on top of PE 12 / 12.1 regular builds.
    - You cannot upgrade from android 11 directly. Formatting data is required.

    PE recovery flash guide
    - Download PE recovery from the official PE website
    - Boot your phone into fastboot mode. You can either
    * hold power + volume down button
    * or `adb reboot bootloader`
    * or use the `Reboot to bootloader` option in TWRP/OrangeFox
    - Connect your phone to a computer
    - Run `fastboot flash recovery pe_recovery_file_name.img` in your cmd/powershell/terminal
    - Hold power + volume up to boot into recovery

    PE 12 flash guide
    - Boot into PE recovery
    - Select `Factory reset" --> "Format data/factory reset`. You phone should say that /data, /cache, and /metadata have been formatted.
    - Go back to main menu and select "Apply update" --> "Apply from ADB"
    - Connect your phone to a computer
    - Run `adb sideload pe_rom_file_name.zip` in your cmd/powershell/terminal and wait until it finishes
    - Reboot to system


    ==============================
    Old guide for android 11 builds:

    Note: The latest TWRP and OrangeFox are able to DECRYPT the /data partition on android11. However, during our testing process, formatting data to bootstrap the ENCRYPTION is still a hit or miss. Some users will get working encryption upon the initial format and boot, but others will have a broken encryption and may need another data format. /data will appear to be encrypted, the recovery will prompt you to enter password, but if you skip/cancel the password prompt, you may see that files are not actually encrypted. This does not happen to everyone using TWRP/OrangeFox, and the cause is still being investigated.
    Therefore, format data with PE recovery is still required for clean flash.
    If you are already on the previous PE 11 build, OTA or dirty flash is fine.


    PE recovery flash guide[Required]:
    - Download PE recovery from the the polaris device page of official PE website
    - Boot your phone into fastboot mode. You can either
    * Hold power + volume down button
    * or `adb reboot bootloader`
    * or use the `Reboot to bootloader` option in TWRP/OrangeFox
    - Connect your phone to a computer
    - Run `fastboot flash recovery pe_recovery_file_name.img` in your cmd/powershell/terminal
    - Hold power + volume up to boot into recovery

    If you have a custom recovery (TWRP/OrangeFox) installed already, you can use that to flash the .img file of PE recovery into the recovery partition.

    PE 11 ROM flash guide[Required]:
    - Boot into PE recovery
    - Select `Factory reset" --> "Format data/factory reset`
    - Go back to main menu and select "Apply update" --> "Apply from ADB"
    - Connect your phone to a computer
    - Run `adb sideload pe_rom_file_name.zip` in your cmd/powershell/terminal and wait until it finishes
    - Reboot to system

    ==============================
    Old guide for android 10 builds:

    Flash guide:
    1. Use latest OrangeFox recovery R11.0 (or newer) or TWRP 3.3.1-1 (or newer)
    2. If you have been using MIUI or any of its variants, you have to format data.
    - you may have to reboot to recovery again after formatting data
    3. Wipe system & data & cache & dalvik cache
    4. Install ROM
    5. Reboot to system

    Note: Official maintainer of PE for polaris has been changed. Clean flash is highly recommended for those coming from the deprecated official build from Oct 2019. I will not offer any help if you've dirty flashed.

    Hi,

    August update is out: https://blog.pixelexperience.org/20...y-updates-optimization-fixes-and-sneak-peeks/

    the new version with the August Security fix can be downloaded from httpsMay://my.hidrive.com/share/qwsshdfnxo#$/
    sha256sum is 18ae24ab82ad6978808238145493cae0c65d9e4ca0032cc25a8e8e4c1e727bc0

    Note: This is the Plus version, as this is what I'm running myself - I have no plans to build the non-Plus version, as I wouldn't test it, and I'd feel bad to provide a completely untested version.

    Regards
