So you dont have to flash your 3 year old flagship phone with lineageos just to get them...
So I now, in an attempt to continue using a perfectly functioning device for more than three years, have the rather ridiculous choice between using my phone without security updates, which banks and various apps will consider safe, or using my phone with security updates, which banks and various apps will consider unsafe.
Yet how long will it be until manufacturers simply start disabling devices more than a few years old altogether, or crippling them, in the name of security?
Yep! One major "other thing" is Snapchat, which really sucks since it's a communications/messaging app that can't be used in a Web browser either, so if you ever start to fail SafetyNet, you'd better hope you have some other means of contacting all of your friends on it.
On the Apple side it generally hasn't been so bad (the iPhone SE has gotten 5 years of updates, which is pretty much unheard of in the smartphone world), but Android still remains pretty miserable in this regard. You're lucky if you get one major version upgrade during the life of your phone.
