Which Android Phone is the least bloated and the most “free”?

As a stock experience, the google pixel phones are unbeatable, pretty much the "reference" edition of android phones. The nothing phone, made by one of 1+'s co-founders, is also fairly clean and has a different set of features.

If you're willing to get your hands dirty, then you can install https://lineageos.org on several brands of phones (https://wiki.lineageos.org/devices/), and if you're willing to ditch android altogether then the grapheneOS project is worth looking into.

The Pixel line of phones supports both lineageOS, grapheneOS, and comes fairly nice stock so I'd wholeheartedly recommend it

I can tell which is the most,which is my Samsung. Thing came pre-loaded with so much hot garbage (and still is). And I bought supposedly mid range one worth ₹ 30K. The most creepy one is something called Ironsource which is an ad service to install random apps or something.

I’d be impressed with an Android phone that actually charges when I plug it into the charger. Every Android phone and tablet I’ve had frequently will be at 10% charge then I plug it in for an hour or 10 hours and come back and it is still at 10% charge.
