OPPO A 6x 4G vs Samsung Galaxy S25+
Our Verdict: The S25+ leads on camera hardware with a 50MP main sensor to the OPPO A 6x 4G's 13MP, plus a 12MP selfie camera against 5MP, and only the S25+ is a 5G phone; the A5 2020 6x 4G maxes out at 4G. There's more battery in the A5 2020 6x 4G, 6500mAh to 4900mAh, which should mean longer between charges in day-to-day use, and storage goes higher on the S25+, up to 512GB against 128GB. Only pay up for the S25+ if you'll use what it offers; if not, the A5 2020 6x 4G makes more sense.
The A5 2020 6x 4G is the cheaper one to own: around £257 over a typical contract, £618 less than the S25+.
