OPPO A 6x 4G vs Samsung Galaxy S25 FE
Our Verdict: The Samsung Galaxy S25 FE 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 FE is a 5G phone; the A5 2020 6x 4G maxes out at 4G. The A5 2020 6x 4G has the bigger battery of the two, 6500mAh against 4900mAh, which should mean longer between charges in day-to-day use, and storage goes higher on the S25 FE, up to 512GB against 128GB. The S25 FE is the one to have if you want what it adds, but the A5 2020 6x 4G is the smarter buy if you'd rather keep the money.
The A5 2020 6x 4G is the cheaper one to own: around £257 over a typical contract, £317 less than the S25 FE.
