Key Buying Criteria for Best Phone Under $700
Form Factor and Display Construction
Form factor alters daily phone use. Folding mechanisms allow big screens to fold into compact square shapes for tight pockets. Rigid glass designs offer traditional flat screens with thinner bezels and fewer moving parts.
Samsung Galaxy Zflip7 FE Cell Phone (2025) brings large folding display into sub-$700 market. Samsung Galaxy A57 5G (2026) uses rigid Super AMOLED Plus screen with slim bezels. Buyers wanting simple flat glass should choose traditional designs; buyers needing maximum pocket space benefit from folding panels.
