Question:

Why does my phone show more available storage after upgrading to One UI 6.0?

Answer:

Before One UI 6.0, Galaxy phones used binary (base 2) units when calculating available storage. This means that 1 byte = 8 bits instead of 1024 bytes = 1 kilobyte (decimal). Due to this difference in notation types, there might be some discrepancies in how much storage space is displayed

<The differences of calculation method>

1. Used GB type of decimal notation : Total storage capacity
2.  Ssed GiB type of binary notation but displayed as GB type of decimal notation : System/Files/Apps storage capacity
• Capacity with GiB type looks larger than GB type

<Notation of Storage space on the device installed or updated with One UI 6.0 (Android U OS)>

•  Old : Binary notation(GiB)
•   1 GiB = 1 * 1024 * 1024 * 1024 bytes

•  New : Decimal notation(GB)
•  1 GB = 1 * 1000 * 1000 * 1000 bytes
