Samsung Galaxy A12 vs Samsung Galaxy S24 Ultra
Our Verdict: Same maker, different budgets: the Galaxy A12 is the cheaper option and the Galaxy S24 Ultra the premium one. The S24 Ultra leads on camera hardware with a 200MP main sensor to the A12's 48MP, plus a 12MP selfie camera against 8MP, and only the S24 Ultra is a 5G phone; the A12 maxes out at 4G. The S24 Ultra has the stronger screen, bigger at 6.8" against 6.5" and sharper at 501 PPI, and the S24 Ultra offers up to 1TB of storage versus 128GB on the A12. Only pay up for the S24 Ultra if you'll use what it offers; if not, the A12 makes more sense.
If you'd rather pay up front, the A12 is the cheaper buy at £63 SIM-free.
