At this point you should consider that all your devices are compromised or compromisable.
the amount of data gathered by your device's OS , is akin to a surveillance tool. Microsoft, Google and Apple have shown an ever growing appetite to siphoning user data back to their servers. and no consumer really has an extensive view of what is gathered. if you want sovereignty over your device a linux OS you compile yourself from source is the only guarantee you can rely on .
I bought an affordable xiaomi phone. and I was floored by how much data the device is trying to collect and how restrictive this vendor version of android has become. they have replaced stock android apps with their own apps that all try to phone home. you can't even change your ringtone straight from the config panel. it redirects you to xiaomi's propriatary app just to replace the ringtone with one that is already store on the phone. their proprietary shit apps keep filing my firewall's blocklist log.
Unfortunately Lineage OS stopped supporting xiaomi phones at least 2 years back. they only focus on pixel phones now. Xiaomi catalogue is quite big. and the amount of their cheap phones sold is 20 times bigger than pixel. but I guess Lineage is only focused on what phones westerners use.
