What Samsung device are you using? My initial thought when I saw the Fold was that it was a gimmick but I'm looking to do some long term travelling and I'm starting to come round to it, especially with Dex thrown in the mix. The RRP is absolutely eye watering though so if I was going to dip my toes in it would probably be with a second hand device.
I'm using a Fold 4, but would've preferred on the Flip series given its smaller footprint. But Samsung made the asinine decision to enable Dex on the Flip series (could be due to thermals?).
Dex actually works starting with the S20 series I believe, with the same feature parity as the latest devices. So you could pickup a cheap used S20 device to try it out.
