Samsung Galaxy A90 128GB 5G Mobile Phone £289 @ Argos
Nice price on this high-end A series phone with 5G. 1/2 price on RRP though I think it's usually around £400-£450.
Recently confirmed as one of the Samsung phones to get 3 generations of Android OS support (and I believe this phone started out on Android 9).
