I think it's just the amount of love for game consoles is much higher than phones, where people are a bit complacent.

I do agree it should happen more often.

Consoles have extremely limited variations, less variables to mess with. A ps5 is a ps5, but a Samsung Galaxy 25 isn't the same as a Samsung Galaxy FE25

As someone else pointed out, there's a shit ton of different phones. In 2012 alone, how many different "Samsung Galaxy ...." did samsung release? Wikipedia lists 6

That's 1 company, with 1 brand name in 1 year. Each with different hardware and as of late those phones have been harder and harder to even open. However, there's a handful of models of "PS5" standard, slim, pro. They are also very easy to open requiring regular tools your average joe is likely to have, in fact sony encourages this in case you want to upgrade your SSD. It's a lot harder to keep a system secure if the user can poke and prod the hardware, i mean the Wii's security was literally beaten by tweezers

Good news, a new exploit has been recently found that can unlock the boot loader of several older Sony phones, even the Japanese models which were not unlockable until the discovery!
