Size of the handset is and will remain an endless discussion as you can read here.
For this and many other reasons (customer expectations) the big phone manufacturers keep on pumping out model by model each month in hopes to suit enough customers to gain win.
After all it’s just a compromise as there are yet no fully customer tailored phones.
In terms of size there is not much that can be done. Blowing up or shrinking palms is just as impossible as doing so with devices. I e.g. simply use my fingers to assure a tight grip. It works just fine for me.
On the other hand I do wonder how come I once in a while meet people having spent money on a new device but not even being satisfies with the size.
So for them obviously other attributes, maybe the OS or else seems to be of higher importance than a perfect fit in their palm.
Also I could read of other individuals who did not purchase the FP2 because it would not meet their size expectations.
Because of such imho secondary requirements the big players always have a reason for pushing the next only slightly different model through their pipeline.
Anyway no matter what’s next, anything coming out after I have enjoyed my FP2 since 3 years would at least have to meet the same technical level, nothing less.
Advancements usually move forward not backward. The only alternative I would consider actually would be a Shiftphone. Technically they are ahead. Still though my FP2 operates just too satisfactory atm.
Btw. size is relative.
