Kill the app causing it. Turn off the notifications. If all else fails, then you're left with the dark side of jail breaking and using a custom ROM.

“What do you want from me, blood?”

I use adguard which blocks ads in all apps but every now and then it gets turned off without me noticing, like once every two weeks, so when I play a game or something and and ad pops up it really feels like this. I never see ads anywhere on my phone or computer so it's like seeing a monster who got past my defences.

When somebody shows me a youtube video on their phone but instead of simply using a browser with ublock they use the app 😭

As long as Android remains linux-based there will be methods of getting rid of anything

"Now someone knows everything about me!"

Some great Ad blocking options:

1. Root+AdAway
2. Use ad blocking DNS
3. Use a VPN with ad blocking

Sucks we live in a world where you have to actively block ads on a phone you paid for with Internet you also pay for, but any one of those options will greatly improve your phone experience.

Me, not knowing where my phone is or the last time I used it:

It also does help to check the app if it uses ads and it's not crippled. Unfortunately most people tend to just jump in because the app looks shiny or because their favorite celebrity uses it.

Firefox on Android is pretty good and you can still install an ad blocker.

Pihole, adaway, firefox+ublock and newpipe. Layered defense.

I would say simply to avoid buying phones from ad-companies, but more generally... if you buy hardware from vendors that respect ownership (i.e. that have user-unlockable bootloaders) then you don't really have to worry about this kind of thing, as even if the company turns evil later, you can probably flash the phone with a 3rd party rom.

Like most others here; I don't see adds on my phone. Now when I use someone else's, or a 'smart' TV or a library computer…

Y’all chrome users?

Would be a shame if Android disabled sideloading entirely like apple.

If you don't review the app permissions in your phone, uses apps from Google Play, don't uses DNS filtering, you even will see personalized ads of products near your home with an "Hello" with your name and your photo.

Privacy is difficult to obtain in Desktop, but mobiles, at least those with a stock OS, are spyware by definition, never good to store important data in these.

Use Firefox or vivaldi and download the adgaurd app from f-droid

My lifetime Adguard licence has lasted for a few phones now. I think it started on the Note 3.

Using RethinkDNS for on-device blocking, but also let it make a wireguard tunnel to my house so I can make use of my PiHole at home.

Which movie is this from?
