I have to replace my current faulty phone. I'm probably going to be restricted to a pre-owned one and looking to spend around £80/£120 but I want one that has a removable battery as I don't appreciate built-in obsolescence !! From what I have seen, a lot of phones that have removable batteries are going to be about 3 years old and have an older OS installed. Some say things like Android 6 updateable to Android 8 etc. I have found that more and more apps will not now run on older OS.
My question is:- can ANY phone be updated to a latest OS or is there a limit on what they can take. Could someone explain to me how I will know what the latest OS a phone can take - what limits its upgradability??
