Android is very far from linux desktop. And it is private, its is google services that are bad, therefore we can have things like calyx and graphene os still be private.
Personally, I only care about the code. When I say maybe there are people who worry about walled gardens and cloud providers who take ownership of your data, I am not one of those people. That's not what I actually care about. That's not what I do. What I do is code. What I care about is code.
google through only the web, what a fucking joke. if you have a google account check your activity history. it will list the times you have opened an app.
if you don't have a google account but your phone has google services, don't be afraid that you can't check it, they're still harvesting it.
want to avoid it?
Step 0: don't by samsung. xiaomi neither, they plan to make you unable to execute the next step.
Step 1: unlock your phone. take ownership into your hands. but back up your photos, the 2FA Authenticator app's data and whatever else is important, because it will get deleted.
Step 2: install a privacy oriented custom ROM.
Step 3: profit
keep bank services contained in the firefox browser. if they don't allow access there, switch banks, you'll be better off with a smaller one anyways.
GrapheneOS for google pixel phones, otherwise CalyxOS, DivestOS, maybe even IodéOS. All of these are Android but with better defaults, without irremovable spying garbage, and with some features nowhere else available.
if your phone is not supported by these, check LineageOS. or plan your next phone purchase according to the compatibility list of the above. if you're going for longevity but you don't need a flagship, Fairphone is agood choice, if you can look away from the lack of a JACK.
If all else fails, you can try using whatever the lastest community supported fork of Universal Android Debloater is. It uses ADB to remove bloatware, which bypasses vendor locks on keeping certain apps installed.
Obviously no real replacement for custom ROMs, but it's better than nothing.
I’m a broken record: block Google (or whomever) with network-based blocking (IP and/or DNS), these guys have third-party tracking in virtually every website and app.
Almost every B2C company I've worked at, I've written or had my devs write proxies for whatever trackers we use. The reality is that every company to whom this data matters to figure out their business model will proxy their trackers. If they don't they need to fire their lead engineers.
It's actually pretty easy to disguise this traffic even to the point where you can use the originating server/cdn to interleave the tracking with the content source.
Phones is absolutely a valid point these days, IMO OS > web + web browser in terms of what you can get.
MS and google both know what porn you are looking at. What you buy from your PC etc... MS knows how much time you are spending playing games + has screenshots of all your encrypted conversations etc...
There are so few native desktop apps these days, it's all on the web.
And the browser can glean a lot more about user interaction than just web traffic, like where you hover, what parts of the page you're interacting with, etc.
That's why I said that (combined with phone), Google probably knows more.
