Memory–UK OnePlus 12R: 16 GB RAM / 256 GB storage. China OnePlus Ace 3: 12/256 GB, 16/512 GB and 16 GB/1 TB; the three added memory combinations are Chinese configurations, not UK 12R options.
Storage typeUFS 3.1 storage; LPDDR5X RAMLPDDR5X RAM; UFS 3.1 storage. Current UK specifications supersede the original launch release's erroneous UFS 4.0 claim; OnePlus's correction is recorded by TechRadar. China Ace 3: LPDDR5X RAM and UFS 4.0 storage; this regional hardware difference does not change the UK 12R specification.
