I recently had my phone (Galaxy S21) stop charging and the SIM not be recognized anymore. I wasn't able to figure out why for a while until I opened the phone (it is relatively easy as the back is plastic and it bulges out if you blow into the SIM slot, making it easier to remove by hand). Ended up being that an internal cable came loose that connected the bottom board to the main components after I dropped it. It just made me personally very happy that I was able to repair such a minor problem in the grand scheme of things. It really was just "detach the plastic back from the adhesive, unscrew some (~13) screws, reattach the cable, put everything back together". While I'd still love if it weren't that difficult it was all-in-all a very easy fix compared to other things I've done. And yes, while the back still somewhat sticks to the case, is somewhat loose. I probably should replace the adhesive but I use a case anyway so it isn't really a problem. So, it doesn't HAVE to be difficult to disassemble a phone, unless incentivised to do so, it is another revenue stream for manufacturers if they make it so that only they can repair it (pairing components cryptographically, to which they only have the keys to... just give the owner the fucking keys and let them decide...)
