Samsung has recently removed UFS 2.1 from the Galaxy S8 spec sheet. This has happened right after Huawei’s memory substitution scandal on the P10 and P10 Plus. To those that don’t know, Huawei installed different memory chips in the two variants, which resulted in users getting very different read speeds. Seems like Samsung has done the same thing.
During Huawei’s memory substitution scandal, Android Authority reached out to the company, that admitted they are using different memory chips on the P10 and P10 Plus. The two phones feature either LPDDR3 or LPDDR4 RAM with eMMC 5.1, UFS 2.0 or UFS 2.1 for storage.
During the Galaxy S8 launch, Samsung highlighted the use of the UFS 2.1 storage in their new phones. Now Samsung has removed any mention of UFS 2.1 from the Galaxy s8 specification sheet. As it turns out the company is using a mixture of UFS 2.1 and UFS 2.0.
