I would like to have a phone that does not have an "operating system".
well they're little computers, so...
they kind of need a framework to do their computing in.
honestly i don't think it's something you need to be scared about.
if someone is tracking my phone they're going to be bored out of their minds seeing me go to work, to the grocery store, once every couple of months visit a friend, and checking Christian theology discussion boards, looking up things in the Bible, and streaming sermons.
so what?
i mean if you are secretly organizing a rebellion against the government or dealing in kidnap victims or terrorism, maybe you've got something to be concerned over. but as for me, i'm not ashamed of what i do or where i go. a city on a hill cannot be hid - why try?
but i understand your anxiety.
there are a lot of people who spread a lot of anxiety, and many who actually make a lot of money doing so!
my opinion tho is don't be freaked out. you can turn off GPS services and tracking data and things in your phone if you don't want them on, but the thing they're doing with those is trying to show you 'smart' commercials with them, unless you're out committing felonies it's more of an avoid-the-hassle-of-ads thing than anything else. just look through the settings on the phone or get someone you know who is nearby to help you look at them in person. everything that tracks data other than what is necessary for the phone to work as a phone is able to be turned off. the default settings are usually 'on' tho, so it takes a little time to go through setting a device up to be more private.
as a Christian if i'm afraid of being persecuted for my Christianity i think i'm not much of a Christian. apart from that, what am i afraid of? every hidden thing will be made plain, one day.
