Am I FLoCed?
FLoC = Federated Learning of Cohorts
“FLoC runs in your browser. It uses your browsing history from the past week to assign you to a group with other “similar” people around the world. Each group receives a label, called a FLoC ID, which is supposed to capture meaningful information about your habits and interests.”

[Android] Upgrade to LineageOS 17.1 – fix audio bluetooth issue
After upgrading to LineageOS 17.1 I wasn’t able to play any audio via bluetooth connection from my Xiaomi Mi 8.
To fix this issue, just go to developer options and disable Bluetooth-AD2P-Hardware-Offload
and reboot your phone.

[Android] Upgrading LineageOS 16.0 to 17.1 on my Xiaomi Mi 8 (dipper)
Install the Android Debug Bridge (ADB)
https://wiki.lineageos.org/adb_fastboot_guide.html
https://github.com/M0Rf30/android-udev-rules#installation
1 2 3 4 | # check if device is found adb devices # reboot into sideload modus adb reboot sideload |
Or manually boot into TWRP recovery, holding Volume Up + Power when the phone is off. Navigate to Advanced
-> ADB Sideload
.
Update MIUI Firmware
If your current MIUI Firmware does not support Android 10, you have to update it first.
Download the newest MIUI Firmware for your device from https://xiaomifirmwareupdater.com/firmware/dipper/.
Flash the new Firmware via TWRP or via ADB sideload.

Download and flash new LineageOS image
I’m using the LineageOS fork LineageOS for microG. Download it from here: https://download.lineage.microg.org/dipper/ (MI 8 = dipper)
The upgrade steps are the same as for the official rom: https://wiki.lineageos.org/devices/dipper/upgrade. In my case only flashing the new image.
