I currently owns a redmi note 4, Indian version

the hardware is great.

price is good,

but the software it's literally a spyware/adware, even after removing all the chinese crapware and preinstall adware from the stock rom there are still trying to send my data back to there chinese server,since removing some of there system app will crash the stock rom

So if you are thinking of using stock rom, your privacy is at great risk.

You might want to flash a custom rom. LineageOS is quite popular these days.

What app is that for the firewall?

AFwall+

but you have made it irritating for user without privacy pass to vist site that use cloudFlare, creating a environment that force user to install privacy pass.

How are you connecting to these sites?

normal Internet connection , no vpn or proxy, just an ad blocker

me too, and the worst thing is that, i am surfing those side from same ip, browser, location and even the same session,

just open a another site in a new tab and again the same ugly captcha.

It simply mean that cloudFlare is forcefully trying to sell there so called " privacy friendly" browser fingerprinting extension to user.

yeah and that's why i block it assess to internet using afwall+

already participated in the survey.
