What’s an OEM?
OEM stands for “original equipment manufacturer”. In the smartphone industry, this term refers to companies who manufacture their own phones in their own factories.
Some examples of Android OEMs are Samsung, LG, and NUU Mobile.
What’s an ODM?
ODM stands for “original design manufacturer”. These companies also own factories where they manufacture phones (often in huge quantities).
Then the ODM sells these phones to other companies, who re-brand the devices with their own names and logos.
This is often referred to as “white-labelling”.
