It is intended. Developers calculated, which frequencies of CPU drain battery the least. It is like this - slow clock takes less power but longer time to complete a task. High clock is the other way round. Since battery drain is power multiplied by time, there is no obvious way to say, which settings is better.
The new kernel uses frequencies, for which measurements shows the least battery drain. This should be effective, when CPU has some load. I'm not sure about situation, when CPU is mostly idle. But I have installed newer version of ArrowOS and I can't see much differences, so the kernel is not bad.

How can I change the height of the status bar?
I resized my screen with "wm size" to sit under the camera but the status bar is still massive.
I already tried G-visual mod but that only modifies the dimens.xml and whatever settings I chose the dimension of the status bar stays the same so I imagine dimens don't control it (that would explain why changing the dpi doesn't affect the status bar either)

Anywho if someone knows where to look I'd appreciate it, cheers.

after installing 23.7 update, flashed magisk again, but bootloop...
anyone else experiencing this?
dirty flash from arrow may version,
i get error message
unable to ope block device...
failed to mount /data
18:23
i install arrow again and it's back working
maybe i need clean flash? i thought it's not mandatory when upgrading
As developer said in previous post, due to changing to oss vendor, the new update must be flashed with clean install. From now on you will be able to dirty flash future updates.

I see, however other devs do not do this, consider that, at least for me, 90% of the time my device is in idle doing nothing, so i'm not sure how a high base frequency help in this specific case.
Best thing to do should add an option and let the user decide what is the better value based on the personal usage.

Are you using the last 0728? Are you testing it? Anything to report or is working fine for your device?
No, I'm still on the trustworthy 07.09 😅 I will wait for a few updates to see if the new vendor version has good feedback. I'm not in experimenting mood and I only format data to switch to new version if everything is working fine.

Same. :D
That's not it, that's to change the sizing of the homescreen grid.
I'm asking about the height of the status bar, usually its value are stored within the systemui.apk but in this rom it seems it isn't stored in the usually dimens.xml
You are right, removed my reply, believe you were talking about the drawer. Never found an option to modify this one.

If you mean the 07.09 build I uploaded it. Link is in the post #725 in this thread.
If someone need i have 07.09 but vanilla version.

Btw, is possible to rename the microSD instead of "android"?
Today i bought a 128Gb one as backup for data and for install new roms after a full format but i can't find an option to do so.

If you have a card reader for SD card, there's card adapter to insert microSD and transfer to SD card.

Some laptop and PC has built-in SD card reader.

Yes, the microSD i bought also include the adapter, but i do not have the card reader on my desktop unfortunately. Anyway i bought a USB 3.0 microSD and SD card reader combo via online store.

Xiaomi Poco X3 Pro
I extracted the Boot.img from ArrowOS community build 07/25 and patched it using Magisk to root. Below screenshot shows the root partition has almost no free space. Is that normal for X3 Pro? I'm sorry if the question sounds stupid 😅

Seems your partition shrinked, not normal, but i never use magisk for this purpose, just for root explorer to manage folders.
Once i installed ArrowOS i just flash magisk via twrp then boot to the os and complete the installation inside the app, never touched boot.img at all.

About CPU frequencies. I think they are wrong!
See the previously quoted information:

There are measurements for SD 855 and SD 855+. Poco uses SD 860, which has max frequencies like 855+.
The most efficient frequencies for 855 are following:
liitle CPU: 1708Mhz
middle: 1401Mhz
big: 1804Mhz

Lowest effective frequencies for 855+:
little CPU: 1478Mhz
middle: 825Mhz
big: 1171Mhz

I don't see why 860 gets effective frequencies from 855, when its CPU is probably the same as 855+.

    Is there any chance to get version from 22072021? That in download site is 27.07.2021. I need earlier build, only that works fine. No reboots :)
    I have Arrow-v11.0-vayu-OFFICIAL-20210723-GAPPS version on my HDD. I could upoad it in cloud if needed.

    I updated #2 with a possible solution for users facing ghost touch problems in their units, this has nothing to do with ArrowOS; this is something at HW or FW level, people are able to fix it while rolling back to 12.0.4.0 or 12.0.6.0 firmware (you will need to boot full MIUI rom for them to do their magic on partitions)
    Even if MIUI fixes it in the latest releases, we might not know how as they do not publish changes made to their kernel source rather publish the base/initial sources only
    anyways, read more at the FAQ section in #2
    Just to be clear, I never faced these issues as I unlocked on the 7th day and never went to MIUI again nor flashed any other firmware, more than 98% of the users also do not face it at a regular basis. I have a bhima 8/128gb variant (Indian vayu with no NFC)
    Good luck

    who is developer of this ROM? will u fix brightness problem at next update and when? if no pls inform, i will move to lineage or crdroid, lowest brightness on arrow is trash
    Developer of this ROM definitely is not paid by Xiaomi themselfs and is not obliged to spend his valuable time to improve / fix stuff on a ROM that is voluntarily maintained, yet he does. Instead, be thankful that OP still improves upon an AOSP based ROM which X3 Pro is not designed for originally. Please do not ask for ETAs. If you have any problem about the ROM itself, follow this guide by OP: https://blog.arrowos.net/how-to-report-a-bug/

    You can download ArrowOS Recovery if you like or use other 3rd party recoveries

    FAQ::

    Tip: If you are new to custom ROMs, I would suggest taking a TWRP backup/partition backup (usually: persist, efs, firmware partitions, etc) saved in your cloud or computer.

    Q1: How can I update to a new update?
    A1: Flash ArrowOS recovery and download and install the update from the OTA Updater application OR Download from arrowos.net [codename: vayu] boot to TWRP and flash it; if you are using ArrowOS recovery, copy build zip to external storage (sdcard, USB otg etc) and install via "Apply system update option"
    If you are on PC, you can also use adb sideload while being on recovery

    Q2: Why is Mi8 (dipper)/walleye oreo or any other device's build fingerprint and desc props/values are used?
    A2
    : As most of the custom ROM users might be aware that SafetyNet cannot pass with devices own build fingerprint props due to the multiple checks or other aspects which is unknown, done by the OEM/Google which fails hence nowadays devices are generally spoofed with build fingerprint and description props of devices which passes CTS/SafetyNet like from a device with Android Oreo or Pre Android Oreo (walleye oreo; mi8 oreo, etc) or from latest Pixels (like redfin)
    This device as of now uses Mi8 (dipper) build fingerprint and description to pass SafetyNet!
    (In future release: It can change to Pixels or some other device too just to "Pass SafetyNet checks") hence don't consider this as some lame reason to spam or message about.

    Q3: Facing ghost touch issues on your device?
    A3:
    This issue has been recognized by Xiaomi as a fault in their MIUI firmware, I am not yet sure if this is completely a hardware fault or just a firmware fault with specific variants
    I have an Indian 8/128 variant and I never faced such issues.
    Since Xiaomi does not release newer changes done to the kernel source, we are stuck with the initial R source release hence we don't know what changes they made to fix it on MIUI if they ever did
    But, some people have fixed ghost touch issues by :
    * Flashing MIUI 12.0.4.0/12.0.6.0 full MIUI rom, booting to it, setup up everything (like registering the fingerprint, etc), and then moving to custom ROMs.

    [* Using 120hz? (not confirm but 2 users have suggested doing this has solved sluggish touch issues for them)]

    If this method works for you do not update firmware unless you are sure that will work
    This is not a global issue, only a limited number of people face it!
    Also, users have faced ghost touch issues on MIUI 12.5.3.0+ versions aswell, so this is not something custom from related! It is hardware/firmware level

    Do not report bugs with mods or custom kernels.

    You can chat with me on Telegram: https://t.me/kubersharma001chat

    Hey. just wanted to notify you all that I am going to remove the "Smart Charging" feature in future builds, Also I suggest using mods/ modules which simulate similar behavior as the smart charging feature IS NOT RECOMMENDED!
    BECAUSE:

    A bunch of Xiaomi devices (at least vayu, surya etc for sure) (or lets say some QUALCOMM devices in general too) have somewhat buggy PMIC ( i.e Power Management IC) and facing the issue is rare in most scenarios (some can face it without using these features too) till you don't mess power_supply or anything related to PMIC mods or features like smart charging, idle state charging, those Magisk modules for smart charging like ACC or whatever can trigger the PMIC to bug out as well and in that case your battery will be drained, won't charge unless you reboot to bootloader till the time you can. If you don't do that and let it drain (which I remind you might be quicker than usual) it might just go DEAD.

    Ref: https://github.com/lybdroid/poco-x3-pro/issues/1

    Most people might not face the issue, but still, there is a chance, and let's not risk it. I would suggest avoiding draining your battery to 0.

    I am not saying the above-mentioned features or mods are bad or broken but there is a slight chance something bad can happen, so my removal of this feature on vayu is just a safe play till we know something better
    "Be safe than sorry"
    11
    Fixes/Changes done for next build/update:
    - Yellow tint on screen
    - Lowers vibration intensity to a decent level
    - Force volume steps to 25 as some MIUI vendors are forcing this to insane 150 volume steps, yikes.
    - Fix Recents Overview sluggishness
    - Ship GCamGoPrebuilt instead of AOSP camera2
    - Other minor improvements and fixes.

    BTW, Incase anyone wasn't aware you can see last 24 hour active/installs statistics here:
    vayu is now under top10


    Changes for Next update:
    Fixed WFD showing green screen while casting to laptop
