I have an android phone (S7 edge). Before I got this phone, I was a light user of snapchat. On the new phone, Whatsapp, Facebook and Instagram were pre-installed. I set them up, they started working perfectly. I downloaded snapchat. It crashed on login. I literally could not get it to work on my brand new flagship device. That's my reason.

PS: also a millennial here, not very crazy though, regrettably
