Are you privacy conscious, but you realized you don’t actually have any options? You can either use a dumb phone, a ridiculously overpriced iPhone or Google infested Android. There are literally no other options unless you sacrifice everything that makes a smartphone virtually “smart”.
So, you’re stuck with Android with all its Google shit. There is a cure for that. It’s called Blokada and it seems to be so effective Google removed it from GooglePlay because it was “going against their business practices” (which just means it blocked their ads and data hoarding). You can also grab it on F-Droid Android software store and if you still have doubts, you can also check Blokada source code…
How does it work?
In an essence, it works as a local VPN, so you don’t have to root your device. Just install it from its webpage (you’ll have to manually allow installation of a 3rd party app, under Android Oreo it should give you access to controls for this directly with the popup, at least on my Xiaomi Mi5 it does) and fire it up. It’ll connect as VPN service, but it’s not really redirecting traffic anywhere, it’s just a neat trick to filter traffic without having to root the phone.
Blokada is using blacklists just like AdBlock, AdGuard or uBlock. It’ll block ads, trackers and even allow you to change DNS to whatever you like.
It gives you a huge selection of various blacklists as well as DNS servers and also has a whitelist where you can exclude apps from filtering in case they get broken or you want to support the devs of that app specifically by allowing ads.
In general, not many apps have problems with it even though I’ve removed most of predefined whitelist exclusions. Some banking apps may refuse to function when any kind of VPN is enabled and since those apps can’t differentiate from actual VPN or a local VPN like Blokada, you’ll at least know what is causing the problem and you need to turn off Blokada entirely for the time you want to use such apps. Whitelisting doesn’t seem to help since those apps seem to detect VPN of any kind is on and just plain refuse to work properly.
Does it work?
Can’t say for sure other than my battery seems to last for quite a bit longer now, I’m not seeing any ads anywhere, not even on Youtube (could be just that I watch videos without ads), but the notifications do show a lot of trackers being blocked and the number of total blocks is in the thousands after just few days of using Blokada. I guess it’s working alright.
