Honestly, yes. I don’t personaly used Calyx VPN or Riseup because, in my experience, the download and upload speeds are terrible. Calyx is a reputable group, however.

Hey, one option I could think of was the Moto G7 by Motorola. It is slightly bigger than the iPhone 13 mini (6.18 x 2.96 x 0.31 in), but it is supported by Lineage OS.

It’s actually my personal device of choice, and it works pretty well with Lineage. I have smaller hands, so it is perfect too.

Did you ever try looking into this specific model?
