Similar to you, I don't care about mobile phones anymore. Instead of fancy hardware or features what I care is simple, secure, and private phone (open-source OS). I used to get excited on new models.
Recently a couple of my friends were talking about "Telegram vs Whatsapp." One is better because it has this feature, etc. They asked my opinion too. I don't care which is better, I only use them because I have to use them for contacting family and some friends. I just need the send text and image functionality (and I don't use it for private / secure texting).
