Be careful with Xiaomi MIUI Android phones removing security manager related apks (that run apparently as root/system) can break the phone and you need to reset via fastboot or so - Learned it the hard way.

For MIUI using EEA region rom and denying consent / nextdns.io and deleting some apks seems to help. However the gallery app still uploads to Xiaomi servers without consent for some filters - overall it's my last Xiaomi. Lineage might work fine but I wanted to avoid all the complications of unlocking bootloader.

No ads after debloating, it's fast but in the end I felt I can't have trust in Xiaomi.

Still Google sends the most blocked beacons. I'm at 20% blocked requests of all requests for my light phone usage.
