I'm on my second iPhone SE; I love the size and simplicity of it but my new (used) one is so faulty and glitchy that I'm getting a refund. So the question becomes: what to replace it with? Another used SE, a used 7 or 8, or should I make the jump to the XR? Friends love their XRs but I'm not a fan of how large they are, and well, it's an investment. Anyone go from the SE to another mid-range model or the X series and have an opinion? I don't play many games and mostly use it for email, text, phone, social media, and -- quite a lot -- as my camera.
