Before You Buy:

The Samsung Galaxy S25 Ultra, while boasting several advancements, has faced criticism for certain aspects that may influence potential buyers.

S Pen Functionality Reduction

A notable change in the S25 Ultra is the removal of Bluetooth capabilities from the S Pen. This decision means the stylus no longer supports features like remote camera control, presentation navigation, or Air Action gestures. Samsung justified this move by citing low user engagement with these functions and aimed to reduce costs. However, the starting price remains at $1,299.99, leading to concerns about value for money. Users who previously relied on these features may find this regression disappointing.

Incremental Hardware Improvements

Critics have pointed out that the S25 Ultra offers minimal hardware upgrades compared to its predecessor, the S24 Ultra. The device retains the same 200MP primary camera and similar telephoto lenses, with the most significant change being a new 50MP ultrawide sensor. While software enhancements, particularly in AI, are evident, the lack of substantial hardware innovation may not justify an upgrade for existing S24 Ultra users.
