Two thoughts on that …
- Fairphone told participants of their 25 June 25 launch event in Amsterdam that going for a smaller display (which would be necessary for a significantly smaller device) would be making the device much more expensive. According to them, smaller displays are no longer the “norm” on the market and would have to be ordered from suppliers in much bigger quantities to ever pay off for the phone manufacturer (so Apple can do it because they are able to sell millions and millions of these).
- Don’t know if you already compared the dimensions of Fairphone generations, but the new Fairphone is actually smaller and lighter than its two predecessors FP4 and FP5. It is longer and heavier than your FP2, but width and thickness are actually in FP2 range.
