Mobile Phone Technology

In 2010 Samsung released their Galaxy S range of phones as their flagship phone. These phones have, over the years, developed from the small 3g slightly "cheap-feeling" original to the premium device offered in 2025 as the S25. Screens have become bigger, cameras more sophisticated, more powerful processors, more memory, more storage and all together a much more powerful and desirable device. In recent years the new phones have become an evolution from the previous device without a "killer" feature. That is apart from the move from 2G to 3G to 4G and to 5G in 2020 Becasue of this, and due to the high quality of these phones customers are not swapping as often as previously, with a renewal time of (on average) 3 years rather than the previous 2.

Samsung Galaxy S25 Ultra (2025) is again an evolution rather than a revolution from the previous version, with out much reason for an S24 owner to swap; maybe the changes from the S23 or S22 would make the change worthwhile. The focus in the marketing was again on the camera but this time it is AI that drives these cameras. The new cameras with the new software makes these cameras really good. Otherwise this is a great phone. perhaps the main change is the flat fron t screen rather than the previous screen with the curved edges
