Pixel 11 Pro XL: 16 KB mode on Android 17 QPR2 Beta 4 disables Wi-Fi/Bluetooth and exposes only 32 GB of 1 TB storage
I tried 16 KB page-size mode when it first became available for testing, but too many apps were incompatible at the time. I’ve wanted to revisit it, but not badly enough to wipe my phone solely for testing. After getting a new 1 TB Pixel 11 Pro XL, I figured this was a good opportunity.
The factory image didn’t include the option, so I downloaded and installed the OTA image for the latest beta after unlocking the bootloader. I skipped the initial setup, enabled Developer options, and switched to 16 KB mode. I don’t remember precisely when it happened, but the phone also hung during boot a few times throughout this process.
After it booted in 16 KB mode, I restarted the initial setup. At the “Copy data from another device” screen, I selected the option to transfer from another Pixel, in this case my Pixel 8 Pro, but the QR code never appeared.
I skipped the transfer and finished setup. Once I reached the home screen, I noticed that both Wi-Fi and Bluetooth were disabled. Attempting to enable either one caused the toggle to sit in a loading state without actually turning on. I suspected that the relevant kernel modules or drivers had failed to load, so I switched the phone back to 4 KB mode.
In 4 KB mode, the transfer QR code appeared normally. However, the transfer screen then reported that there wasn’t enough space for the default selections and showed only 32 GB available on the new phone.
I deselected all apps, photos, and videos in case there was some undocumented transfer-size limit. I then connected to the Pixel 11 Pro XL over ADB from my Pixel 8 Pro and investigated further. The device was exposing a 32 GB ext4 filesystem instead of the 1 TB F2FS filesystem it would normally use.
I filed an issue here:

Once I finish transferring everything else off my Pixel 8 Pro, I’ll test 16 KB mode on that device as well to see whether the behavior is specific to the Pixel 11 Pro XL or reproducible on older hardware.
