On Friday, Chinese phone brand OnePlus announced it will refund users who have purchased the OnePlus 12R 256GB model, after the company recently confirmed that all models of the OnePlus 12R are equipped with UFS 3.1, not the previously claimed UFS 4.0, the highest level currently available. UFS (Universal Flash Storage) is a high-speed flash storage standard used in smartphones for faster data transfer and access. During the OnePlus 12R launch in January, the company introduced the Trinity Engine, a new set of software algorithms aimed at ensuring fast and smooth operation of phone memory and storage. However, OnePlus mistakenly claimed that the storage enhanced by the Trinity Engine in certain versions would be UFS 4.0, when in fact it is UFS 3.1. Those who purchased the device have been told to contact customer service, with the refund deadline set for March 16, 2024.[[OnePlus Community]
