You can check this by covering the top ear piece portion of the tab. if your sensor works perfectly screen brightness will get reduced.

I'm using latest Google Android 13 w/GSM GSI. I thought this thread was generic for "any" GSI? Which GSI already has the overlay? Treble?

First of all, ty for the guide. It worked on my SM-T227U (Canadian Cellular Variant)

However, I am struggling with the launcher crashing for the PixelExtended GSI. I cannot access the homescreen and system navigation (gesture nav, 2-button nav, 3-button nav)
I just want to check what you mean by 'same launcher as before'. Is it a special launcher you installed?

Thank you in advance :)

Can you tell me why "battery stats" aren't available in the ROM in the OP?
It's great, apart from this.

    fastboot commands

    fastboot commands. GitHub Gist: instantly...
    gist.github.com gist.github.com

    --info--
    Sam did not provided " fastboot mode" for all devices. only "Odin flashing tool".

    What is the FasdtbootD?

    What is FastbootD? How to Boot to FastbootD Mode

    In this tutorial, we will explain you what is...
    www.droidwin.com www.droidwin.com
    *Limitation of FastbootD
    FastbootD not the same as regular "fastboot", impossible to use fastbootd without " Dynamic partition. etc., dynamic partitions are automatically created, resized, or deleted as needed.

    *FastbootD has access in logical partition like Super Partition.
    ( have odm +product+vendor+system partition inside) , Because dynamic partitions are implemented in userspace, partitions needed by the bootloader can't be made dynamic. For example, boot, dtbo, and vbmeta are read by the bootloader, and so must remain as physical partitions.

    then
    You can't uses by fastbootD performed
    Code: 
     fastboot --disable-verity flash vbmata vbmeta.img

    ✓ Not enough space to resize partition solution
    Solution:
    Removing stock system_ext and/or product from fastbootd is enough, like so:

    ***Don't uses this command

    "fastboot delete-logical-partition product"

    why ?
    the product partition, with around 1.3GB in size isn’t even required by the GSIs.

    then you can delete data on product partition.

    *(Didn't delete product partition itself but deletes only data inside this partition , then android will auto-resize product'spartition.)
    Do this.
    Code: 
     adb reboot fastboot

    Code: 
     fastboot erase product

    set the size of the product partition to 0

    Code: 
     fastboot resize-logical-partition product  0x0

    To verify if the partition size has become 0.

    Code: 
     fastboot getvar all

    If one of the lines shows the below code, then the process is a success.

    Code: 
     (bootloader) partition-size:product:0x0

    partition-product.PNG

    or
    >fastboot erase system_ext
    >fastboot resize-logical-partition system_ext 0x0
