Samsung Galaxy A17 4G vs Samsung Galaxy S25

Our Verdict: Start with Galaxy A17 4G if a larger 6.7-inch screen matters most. Galaxy S25 pushes back with up to 512GB of storage, which may matter more day to day. Current contract pricing favours Galaxy A17 4G: roughly £109 over the term, compared with about £400 for Galaxy S25. Deal availability is stronger for Galaxy S25 right now, although the final choice still depends on tariff and storage. Pick Galaxy A17 4G if you want to keep the total cost down, but lean toward Galaxy S25 when you want maximum storage.

Over a full contract, the A17 4G works out around £291 all-in, about £302 less than the S25.
