A few words on mobile a "porn"

Why are these new mobile phones so expensive? I can't justify spending $2000 on a mobile phone, not even $500, to be honest. I can book an air ticket to Europe for $2000. I need a simple phone to make and receive calls so does texts. Perhaps WhatsApp might be handy to contact those who aren't living in the list of countries to which Telstra offers free overseas calling. I don't need a phone with a better camera, I have a 42-megapixel camera with a bunch of Carl Zeiss lenses. I don't need much processing power nor ram since I own a few laptops. I might need to install a couple of apps that are needed to assist with my travelling habits. I don't need massive storage, I don't care where would be the fingerprint scanner located at. I don't need cordless charging. I need a simple mobile.

I can't put up with iPhones due to their limited functionalities but they seem to be the way considering their support lifecycle. The Android mobile vendors don't offer security updates and patches beyond two years from the official release date. This makes Android mobiles more vulnerable after 24 months since their release. The iPhones, however, receive updates and security fixes almost up to seven years from their release; making them attractive for blokes like me who'd be fine with limited functionalities but a longer support lifecycle. I'm inclined to buy an iPhone for the extended life support on their firmware alone. The alternative is to buy a cheap Android every two years to keep up with the updates and security fixes. Although I love Androids million times over the phones which have that fruit logo, I hate setting up my mobile on a regular basis. Why can't Android phone manufacturer can't make a phone with extended life support for five years at a minimum?
