I know this is a odd thing for most adults / teens, but I prefer to use a dumb phone over a smart phone.
To me a phone is to make calls and send texts, that's all, a dumb phone is cheap and does the job for me, I dislike smart phones though they serve the purpose of a phone, all that extra crap a computer can do, I honestly don't see a point in smart phones, sure there perfect for people without computers, but kind of pointless.
I don't have to worry about my dumb phone being targeted, or worry about it getting some kind of malware.
It's not connected to the internet (usually) and has absolutely no gpses in them, there good for paranoid people.
Doesn't chew all your data on app downloads, and best of all the reason I use them mostly, is they can last weeks without having to be recharged, carry two batteries and your set, no need to worry about dropping them etc.
Although I used to own smart phones, I just don't see the need for them, a dumb phone provides everything a phone needs, smart phones are more like computerized phones.
I don't have to worry about android malware, hijacking my camera, don't have to worry about dropping it, they last a long time even.
