I'm still on my first gen iPhone SE. Thankfully the apps I use are mostly compatible, and I just use web versions for everything else. Have replaced the battery and screen a few times each.

This phone looks like it might be good replacement but it could also be a bit dodgy. I'm going to wait a bit for reviews before considering buying it https://aiphor.com/products/bluefox-nx1-4-0-android-smartpho...
