I have not updated my phone in two years, because I know the update I am going to get will disable call recording functionality. Phone works fine except that I cannot disable the notification about the update that pops up randomly in hope that I'll click to accept by mistake. Also maybe that's why my phone works well as there are no updates that would slow things down.
